Project title :Harnessing the power of plant social interactions to breed better rice. 



Increasing the amount of food we get from crop plants (their “yield”) is essential to feed the world’s growing population. However, given the biodiversity crisis increasing the area planted is not a long-term solution, and so we need to create more efficient and productive crop plants. Unfortunately, evolved changes of yield for most crops have plateaued, which is a huge problem. Simultaneously, we need to breed plants that are more resistant to variation in nutrient availability to help maintain robust food supplies in countries with different planting conditions and as climates change.

When selecting for increased yields, the correlated evolution of increased competitive interactions can completely stop the expected evolutionary change in total yield, as plants selected for increased production may cause their neighbours to produce less through increased resource competition. Such competitive interactions are underpinned by “indirect genetic effects” (IGEs), which refer to the genes of one plant influencing the characteristics of its neighbours.

When IGEs prevent yield increases, plant breeders face a huge waste of time and resources. Understanding how important IGEs are, which life stages they manifest, the conditions that influence their importance, and the genes underlying any negative competitive effects is therefore essential for breeding crop plants that can feed tomorrow’s populations. However, while appreciation is growing about how much plants interact and even communicate with their neighbours, IGEs are still very much underappreciated.

Selection that accounts for and reduces negative competitive effects should give progeny that produce higher yields from the same resources, i.e., they are more efficient. By estimating IGEs in scenarios where different key nutrients are limited (e.g., nitrogen, phosphorus), we can identify which nutrients are most limiting when plants compete. We can then explore the mechanisms through which plants compete for these limiting nutrients and then devise approaches to develop crops that are more resilient to conditions where these nutrients are at a low level.

This project will use the understanding of IGEs to investigate how we can develop strains of rice with increased yields, efficiency, and resilience to variation in nutrient availability. Rice is a really important plant to study this in as it is a staple crop for billions of people and is known to interact and compete with neighbouring plants. The student will conduct a series of controlled experiments using the extensive collection of rice cultivars at the University of Aberdeen. They will measure morphological and physiological traits in each plant and use this information to estimate direct and indirect genetic effects, how IGEs contribute to evolutionary change, and related questions. Using this information, the student will design selection regimes to produce new rice strains that will help feed the world.

Informal enquiries would be welcomed for a discussion. Please contact Dr David Fisher () for further Information.



This 42 Month PhD project is part of the Anthony & Margaret Johnston Centre for Doctoral Training in Plant Sciences at the University of Aberdeen.
This opportunity is open to UK and International students and includes full funding to cover tuition fees and a stipend at the UKRI rate (£16,062 For the 22/23 academic year).
Funding for international students does not cover visa costs (either for yourself or for accompanying family members), immigration health surcharge or any other additional costs associated with relocation to the UK.
The expected start date is October 2022.



Essential: A 2:1 UK Honours degree (or Equivalent) in a relevant subject ( Plant sciences related degree OR evolutionary biology related degree).

If previous background in plant sciences, then a keen interest to learn tools from evolutionary biology. If background in evolutionary biology, then keen interest to learn botany. In either case a passion for both discovering fundamental aspects of the natural world and applying our insights to solve important applied problems.

Desired: Experience with or knowledge of quantitative genetics, plant breeding, conducting experiments in controlled conditions, plant resource use.
