- 详细技术说明
- A novel variant of Rubisco activase (RCA) with greater activity at elevated temperatures. The RCA variant was identified in wild Australian rice (Orzya australiensis), in which we have shown that it produces more thermally stable complexes up to 42 degrees C, contrasting with RCA from common commercial rice, O. sativa, which forms unstable complexes above 36 degrees C. Photosynthetic activity in O. sativa is halved at 45 degrees (cf. 28 degrees C), whereas photosynthesis rates in plants with our heat-tolerant variant of RCA remains stable.
This technology could be applied to many crops to maintain current yields in traditional growing areas into the future, despite predicted increasing average temperatures from climate change. The technology could also be used to expand the current growing areas of heat-sensitive crops into hotter and more arid zones traditionally considered unsuitable for temperate crops.
