Leaf yellowing genes can be controlled, a solution to the yellow leaf problem

A research group in Japan recently announced that they have discovered the genetic genes that control leaf yellowing in plants caused by long-term drought. The research results are expected to be applied to improving the quality and yield of crops.

A joint research group composed of Researcher Kazuo Shinozaki of the Environmental Resources Science Research Center at RIKEN in Japan, Professor Kazuko Shinozaki of the Graduate School of Agricultural and Life Sciences at the University of Tokyo in Japan, and Researcher Kazuo Nakashima of the Japan International Research Center for Agricultural Sciences used NAC (NAM, ATAF and CUC) genes, one of the plant-specific transcription factors, to study abscisic acid. They used a plant model a href=https://www.zhifujing.org/special/wa/ target=_blank class=infotextkey>frogand created a large-scale gene family composed of at least 00 NAC genes, then selected 7 genes related to stress responses (SNAC-As) from the NAC gene group, and produced 7 types of mutants in which all SNAC-As genes were disrupted. Through careful analysis, the researchers discovered the related genes through which the SNAC-As transcription factor group controls yellowing under abscisic acid treatment conditions.
