Накратко на български

Ензимът Rubisco activase в пшеницата се изследва с цел повишаване на устойчивостта му към високи температури. Това помага за запазване на фотосинтезата и добивите от зърно при честите горещи вълни, за да се осигури храната за растящото население.

Highly Efficient and Thermotolerant Wheat

Issue being addressed The world is facing more frequent and extreme heat waves. This will have a detrimental impact on important food crops like wheat that are susceptible to heat stress. One of the most susceptible parts of a plant to heat stress is photosynthesis, the ability of the plant to make sugars from water and carbon dioxide fixed from the atmosphere. If photosynthesis is impaired then growth and yield of crops will also be impaired and food production will decline, a major problem considering the need of humans to feed a growing world population. Importance to society Wheat along with rice would be one of the greatest contributors to human calorie uptake across the world. Wheat is a selectively bread temperate grass and as such is not able to sustain photosynthesis, growth and yield when temperatures are much above 35 degrees celsius. Considering wheat is grown in temperate climates in Europe, Russia and North America, and such regions are expected to face higher average and more extreme and frequent heat waves, the ability of wheat to maintain current or improved levels of yield will heavily depend on the ability of the crop to withstand these periods of heat stress. In other words, without improved heat stress tolerance of wheat growth and yield the ability of humans to meet the growing food intake of the global human population will be difficalt. Objectives of project One of the key components of the susceptibility of photosynthesis to heat stress is an enzyme named Rubisco activase (Rca) which allows the carbon dioxide fixing enzyme Rubisco to stay functional. The key objective of the project was to enhance the thermal stability of the Rca enzyme in wheat so that wheat photosynthesis, growth and ultimately yield will be less susceptible to heat stress.

Цел на проекта

Meeting the needs for a growing food security in a changing climate is currently one the key challenges for agricultural research, particularly theimpact of heat waves on food production. Photosynthesis is arguably the greatest contributor to crop yield and its reduction will severely affect foodproduction. Photosynthesis is highly susceptible to even moderately elevated temperatures and susceptibility can be in large part attributed to the enzyme Rubisco activase (RCA), one of the least thermostable photosynthesis proteins and the principal activation partner for the photosynthetic core enzyme Rubisco, that drives carbon fixation and hence growth. Considering the susceptibility of RCA to moderate and severe heat stress and its important role in photosynthesis, the need to improve its thermostability is paramount. In this project, we intend to manipulate RCA in order to enhance the photosynthetic performance, and therefore yield potential, of wheat. We intend to achieve this through sourcing and transfer of heatstable variants of RCA from relatives of wheat that have evolved in hot climates. We will identify the genetic diversity responsible for improving the thermostability of RCA through a combination of comparative bioinformatics, newly developed and refined high throughput Rubisco activation assays. State-of-the-art mutational techniques will be used to further modify wheat RCA to create RCA variants with superior thermostability and optimal activity. Improved variants of wheat RCA will be incorporated into elite wheat germplasm by means of genetic modification and breeding programs. This highly refined, technologically advanced and interdisciplinary approach has the potential to dramatically improve yield production in wheat under future climate scenarios. Furthermore, gains to the technical skill-set and the industrial setting of the research will further the fellow`s objective of having a successful scientific research career in industry.
