个人简介
Currently, my research team of postdoctoral associates is investigating the molecular and biochemical bases of the interactions of crop plant photosynthesis with the rapid changes that are occurring in the atmosphere and on diverse strategies to improve photosynthetic efficiency.
Improving photosynthetic efficiency. The yield potential (Yp) of a grain crop is the seed mass per unit ground area obtained under optimum growing conditions without weeds, pests and diseases. It is determined by the product of the available light energy and by the genetically determined properties: the efficiency of light capture (Ei), the efficiency of the conversion of the intercepted light into biomass (Ec) and the proportion of biomass partitioned into grain (η). Plant breeding brings η and Ei for some crops close to their theoretical maxima, leaving Ec, primarily determined by photosynthesis, as the only remaining major prospect for improving Yp. Numerous potential routes of increasing Ec by improving photosynthetic efficiency are explored, ranging from altered canopy architecture to lower the energetic cost of photorespiration by engineering new pathways. Collectively and in combination, these changes could improve Ec and, therefore, Yp by more than 50%. Because some changes could be achieved by transgenic technology, the time of the development of commercial cultivars could be considerably less than by conventional breeding and potentially, within 10–15 years
