How plants weigh the mechanisms of growth and drought tolerance.

Drought stress is the main factor affecting plant growth and development, and it is also one of the important factors restricting agricultural production.
therefore, understanding how plants weigh growth and development and stress resistance or tolerance in arid conditions, and improving plant resistance, is the focus of attention around the world.
The XieQi Research Group of the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences applied the positive genetic method to filter to the dtm1 mutation, which is obviously drought-tolerant, and the drought-tolerant mechanism of dtm1 is not the usually known ABA dependence mechanism, and its drought-tolerant d'ethometer is caused by the decrease in pore density caused by CDKC;2 mutation.
meanwhile, mutants are significantly erstwhile and seed harvests increase due to increased cell division, suggesting that the mutation improves plant growth and resilience.
further studies have shown that CDKC;2 regulates the expression of genes associated with cell cycle and pore development.
therefore, the study reveals how plants balance the mechanisms of growth and drought tolerance, while providing theoretical guidance for biotechnology to improve plant drought tolerance and growth.
the findings were published online June 16 in the journal Plant Journal (DOI: 10.1111/tpj.13609).
