Crops

We address the challenges of enhancing crop yield and crop quality in a changing environment, using a combination of advanced experimental facilities and novel crop modelling techniques. We tackle the big issues of meeting the demands of a growing population without irreversible degradation of natural resources, taking into account climate variability and change and how crop production can adapt to future climates.

Paola Tosi is a Senior Research Fellow. Her main research interests focus on the deposition of storage compounds in grain, particularly cereals, combining research into grain development and the biochemistry of ripening with grain processing quality, nutritional properties.

A large part of her research effort is aimed at understanding the deposition kinetics of storage proteins and of cell wall components, how this relates to the development and differentiation of the various grain tissues and to the amount, distribution and chemical characteristics (particularly polymerizing behaviour) of gluten protein and cell wall polysaccharides in the mature grains.

Increasingly the emphasis of her research is on how environmental effects (biotic and abiotic stresses, crop nutritional inputs) impact on final grain yield, grain processing quality and nutritional characteristics, including macro and micro nutrients bioavailability. These themes are pursued in projects investigating the effect of post anthesis heat stress on grain size and the relationships between genotype, yield and environmental factors on protein distribution in the wheat endosperm, respectively.

Research Title:
PhD in Agriculture, "Harnessing multiple ecosystem services from novel crop rotations"

Research Description:
My research involves the collection of data from a field plot experiment being conducted at the University's Crops Research Unit (CRU) based at Sonning Farm, in Berkshire.

Conducted over a three year period, a number of ecosystem service indicators relevant to arable production have been measured, demonstrating how diverse crop rotations impact and shape multiple ecosystem services.

My PhD is directly related to my previous academic background, and work experience in Ecology. I initially worked as an ecological field assistant for an ecological consultancy, working on mitigation projects for a range of different species from badgers to breeding birds, before moving on to a seasonal ecologist position at an ecological planning and research company where I surveyed protected species, and supervised and trained MSc student interns in the survey techniques that I developed. These placements have really aided my learning and have given me an awareness of the commercial environment and the importance of building relationships.

In addition, it has driven my desire to look at the applied nature of research, and the importance of finding solutions to real world problems.

Career Aspirations:
I would like to work at the interface between science and policy as either a scientist working on an applied area or in a policy role trying to translate science into recommendations and policy options. I am currently an academic fellow at the Parliamentary Office for Science and Technology in the midst of a 3-month placement and really enjoying seeing how scientific evidence can feed into the decision making process.

My passion to pursue such a career path comes from previous worked based accomplishments where I contributed to an Ecological Impact Assessment (EcIA) for great crested newts and hazel dormice, and accumulated over 100 hours of bat survey experience. I really enjoyed the work; it was a great motivator. This coupled with the fact that my PhD studies have highlighted my natural ability to work with statistics make the idea of finding a role that involves communicating statistics, scientific evidence, and putting it all this into practice, very appealing.

Why did you choose Reading?
I became interested in studying for my PhD at Reading when the research group was recommended to me by my Master's supervisor, when I was studying at the University of East Anglia. I heard of the work that my supervisor was conducting, which added to my enthusiasm. The University is also conveniently located; with excellent transport links to get you pretty much anywhere and its attractive campus environment was a key deciding factor, especially as it has recently been awarded its sixth consecutive Green Flag award.

My expectations of Reading have definitely been fulfilled. I am really enjoying my research project and the field work has been really interesting, as is finding answers to real life issues. I have also enjoyed the variety of activities that I have undertaken, and the opportunity to travel and test myself. I have had the chance to attend a number of workshops and more formal courses, which have all been valuable. The University's classes on teaching were particularly good. An experience that has enriched my learning.

I have also had the chance to present my science at a conference, and to participate in some seasonal lecturing in the University's School of Archaeology, Geography, and Environmental Science. I have been a module convener and sessional lecturer for the 2016-2017 Quantitative Analysis of Environmental data course, teaching introductory statistics to under-graduate and post-graduate students. This role has been a principle achievement for me, which involves successfully managing a team, and organising and teaching a module.

I would definitely recommend doing a PhD at the University of Reading. Not only does it open up career paths that would otherwise be unavailable to you, it also provides opportunities to learn skills and gain new experiences, as well as testing your own abilities.

Research Title:
"Leaf-specific weed control on vegetable crops"

Research Description:
My research is intended to address the concerns surrounding the losses of herbicides in vegetable crops. By applying herbicide droplets directly onto the leaves of weeds, I will better understand how this affects weed control while minimizing herbicide inputs and meeting the demand for more sustainable crop production.

In the past I have worked in several roles that look into and test the impact of pesticides and herbicides on plants in order to better protect them. Seeing the significance of this work has driven me to work on this research project, as I now believe that the future of weed control lies in the use of precision weed control systems. I have drawn on my past experience as a Field Trial Officer at Magma Agricultural Inputs, which has benefitted me considerably when carrying out similar trials with herbicides. I quickly realised that being able to work in a laboratory rather than in a field has made it attainable to take these trials a step further, seeing if manipulating just the weed leaves themselves would have a desired influence.

I started conducting research in April 2015, initially operating in the glasshouses to quantify the volume and number of herbicide droplets that are required to control different types of weeds under controlled conditions. I have since taken my work into the field to test the true significance of these results on cabbages, carrying out the same procedure as before with a range of droplet values.

My results have proven the concept of leaf-specific weed control by herbicide droplet application both in the glasshouses and in the field, achieving results of 92% weed control while reducing herbicides by 85%. I have produced two posters so far on my research, with both being presented in several national and international conferences. As well as this I have released my own paper on the topic, titled; "Dose response relationship of droplet applications for the leaf-specific weed control in vegetable crops".

Career aspirations:
I hope to work in the academic sector, in particular being involved with machinery and software development. This area's strong relations with business would allow me to aid and assist the major agricultural issues at an industrial level, while also allowing me to continue my current research, as I am keen to specialise in the kinetics of herbicides, learning more about the new formulations of pesticides that impact crop yields.

Why did you choose Reading?
I chose Reading as the high quality of the work that was being conducted in the School was evident to me when I was studying for my masters. It inspired me and I decided that this was the best place for me to complete my PhD. The variety of research that was being carried out within the School of Agriculture, Policy and Development fascinated me and I could see why it is one of the leading Universities for Agricultural studies.

Whilst completing my masters I also came across the facilities located in the Crop and Environment Laboratory, but it was the glasshouses that influenced the direction of my research. Through the use of this facility I was able to control all the variables required for me to see the true impact of herbicides on crop yields, whilst also carrying out extremely realistic trials that will carry similar results to the field. The relevance of the equipment to my project and significant applicability of these results to the current real-world situation is what not only helped me shape where to carry out my PhD, but also what to actually research.

The other reason I chose Reading was for its Researcher Development Programme (RRDP). The programme has helped me to continue learning skills in writing, and has also helped me to better manage my project and myself as I conduct the project as it supports all of the work that goes into my research, as well as ensuring that I pass the confirmation of registration so that I am able to concentrate on my work at hand.

Research Title:
"Towards the domestication of the local wild edible yam (Dioscorea hirtiflora) in Zambia"

Research Description:
My research originated from a preliminary study on underutilised roots and tubers that I helped carry out at the Copperbelt University in Zambia where I used to lecture. My research follows on from this, looking specifically at the Dioscorea hirtiflora, a species widely utilised for food and income in Southern Zambia, but the local wild Dioscorea species has yet to be cultivated.

I have divided this study into three thematic areas: socio-economic, agronomy and molecular biology of Dioscorea hirtiflora.

For the socio-economic aspect I will be undertaking household surveys with key stakeholders along the value chain of this species to determine its contribution to livelihoods. Once I've understood its societal impact, I will then determine the best agronomic practice for future production or cultivation of this Dioscorea.

Finally I will evaluate its genetic variation using published microsatellite libraries for other yam species in order to establish where centres of genetic diversity are distributed across Zambia. This will help me to understand its genetic variation, as well as allowing for me to pinpoint those locations for Dioscorea which should be protected from genetic erosion during the domestication process.

My research techniques will be tested at the University of Reading to practice and understand the methodology I will be using, before being taken out into the field in Zambia.

Career Aspirations:
I hope to carry on with my research to help contribute to the development of value chains of local indigenous neglected and underutilised species, also known as orphan crops. My current research has suggested that they could prove vital to the agricultural industry in the future, helping to diversify and adapt smallholder agricultural systems to climate change. This could prove vital to enhancing the quality and yield of food, as well as providing income security for those in communities located in developing countries.

Research Title:
PhD in Breeding for yield and disease resistance in the faba bean.

Research Description:
Plant breeding is a very challenging and promising research field and the ever increasing human population needs a significant increase in food production. In fact, such issues that are underlying in global food security are amongst the most pressing in international politics.

My project addresses the instability of yield potential of elite spring bean varieties in high rainfall conditions due to Ascohyta blights, a disease of worldwide distribution that can cause between 15-35% yield losses under certain weather conditions. Considering problems in Northern Europe and meeting challenges of Irish faba bean producers, this research aims to combine Ascohyta disease resistance and yield from autumn planting using a modified recurrent selection scheme.

Career Aspirations:
I see myself working on several research programs either in academia or private institutes/laboratories. By completing my PhD project in this particular area of research, I hope my contributions will provide me with all the appropriate knowledge required to pursue a breeder or geneticist career path.

Expected Completion Date:
February 2020

Country of Origin:
Greece

Why did you choose Reading?
During the last year of my MSc studies, I participated in a three month Erasmus placement programme in Dijon, France, where I became a member of the French National Institute of Agricultural Research (INRA). It gave me the opportunity to collaborate with some great researchers and to be a part of an integral scientific team involved with the molecular lab research undertaken.

That experience changed my career aspirations and inspired my search for a PhD.

The University of Reading is ranked amongst the top research led universities, so it became very attractive to me; especially as much of Reading's world class research is focused on the global issues that affects us as a society, both now and in the future, which is wholly relevant to my own PhD project research area.

In addition, hearing about the Reading Researchers Developing Programs (RRDP) was reassuring, as it provides such vast support, even at PhD level, in terms of the wide range of training sessions, workshops and activities that are designed to help researchers like myself to carry out research effectively, professionally, and ultimately to be successful in my on going career.


Would you recommend a PhD to other students?
Embarking on a PhD is a big decision but I would highly recommend a PhD to those who have an irrational enthusiasm for science and research, enjoy being in challenging situations and have that desire to invent whilst enjoying the teaching-learning process.

So if you have an ambition to achieve something significant and feel a PhD could improve your life and future career, I believe starting a PhD is the key to do this.

Research Title:

'Plant growth regulators and water use in different Rice cultivars.'

Research description:

My research investigates the impact of water scarcity on crop production, which is a major concern for agricultural production in many parts of the world.

Rice, which is a staple crop, is one of the most inefficient crops in its consumption of water. It consumers approximately 40% of the world's irrigation water, and 30% of the world's freshwater resources. Therefore, research to find appropriate solutions to overcome this problem are necessary. Plant growth regulators (PGRs) or plant hormones, which regulate plant development or adaptations to environmental cues, could be used to improve the water use efficiency in rice. Manipulating plant hormones, either endogenously or exogenously, could alter the plant architecture, by increasing the root length of plants to allow them to access water at depth for a longer period of time, and increase their tolerance to drought conditions. To address this, the effects of treating rice seeds with plant hormones on root and shoot development and subsequent drought tolerance are being investigated within my research.

Career aspirations:

On completion of my PhD I hope to continue working within academic research, especially within the field of root systems of crops. My ambition to work on root systems stems from previously being involved with two research programmes to develop Wheat and Sorghum, through selecting, breeding, and adapting new genotypes for arid environments.

Root systems of crops have had little surrounding research, so my research will investigate the differences between plant roots, such as primary length, lateral numbers, total length and the distribution of the root system in the soil. This information will then be useful to plant breeders to allow them to select the best genotypes according to their root system, or avoid genotypes with poor root systems. I am also interested in continuing my investigations into the link between the root system, drought and final yield.

Why did you choose Reading?

Reading has a great worldwide reputation in the area of research I was interested in. It was actually the only university I applied to do a PhD.

Please outline the different kinds of learning experience that you feel you have most benefited from.

This is a difficult one as there was just so many. Given the broad nature of my PhD research and the fact it was part of a European project, I had the chance to undertake a variety of activities including; working in the lab; the field; travelling abroad to present at international conferences and participating in outreach activities. I was able to learn and benefit from all of these opportunities.

Would you recommend a PhD to other students, if so why?

I would definitely recommend a PhD if people enjoy research and are working on a topic which they really like. Doing a PhD is a great opportunity to learn new skills, develop critical think and is an overall great experience. You do have to love what you do as it will take over your life for those three-four years though!
