New Heat Sensing Gene to Help Crops Battle Climate ChangeApril 7, 2021
The researchers modified a completely temperature-insensitive mutant Arabidopsis to make it reactive to temperature again. Upon examining the genes of the twice-mutated plant, they found a new gene, RCB, with products that work closely with HEMERA, the first gene they discovered to stabilize the heat-sensing function. These genes are distributed in the nucleus and chloroplasts. Both genes work together to control a group of master gene regulators that serve multiple functions such as reacting to temperature, growth, flowering, and greening of plants.
The discovery of the second gene could help researchers develop heat-tolerant plants that can endure the adverse effects of climate change.
