HY5 and ABI5 transcription factors physically interact to fine tune light and ABA signaling in Arabidopsis.

Plant molecular biology - 1 Sept 2021

Bhagat Prakash Kumar, Verma Deepanjali, Sharma Deepika, Sinha Alok Krishna

Abstract excerpt

KEY MESSAGE: Cross-talk between light and ABA signaling is mediated by physical interaction between HY5 and ABI5 Arabidopsis. Plants undergo numerous transitions during their life-cycle and have developed a very complex network of signaling to integrate information from their surroundings to effectively survive in the ever-changing environment. Light signaling is one of the crucial factors that govern the plant...
