PHYTOCHROME A controls the DNA damage response and cell death tolerance within the Arabidopsis root meristem.

Plant, cell & environment - 1 May 2024

Huerta-Venegas Pedro Iván, Raya-González Javier, Ruíz-Herrera León Francisco, López-Bucio José

Abstract excerpt

The DNA damage response avoids mutations into dividing cells. Here, we analysed the role of photoreceptors on the restriction of root growth imposed by genotoxic agents and its relationship with cell viability and performance of meristems. Comparison of root growth of Arabidopsis WT, phyA-211, phyB-9, and phyA-211phyB-9 double mutants unveiled a critical role for phytochrome A (PhyA) in protecting roots from...
