Phytohormones Act as Information-Bridges between Light and Temperature Signaling Transduction Pathways

Abstract:

To survive an ever-changing environment, plants must respond to changes in the environment constantly and evolve great plasticity to adapt these changes whilst maintaining developmental and growth processes. Light and temperature are two major factors among numerous environmental stimuli. Their regulations are involved in various developmental and metabolic processes. Moreover, studies have revealed that light and temperature regulate physiological processes like seed germination, hypocotyl elongation and flowering synergistically. This indicates connection exists between these two stimuli response. In this study, we adopted microarry analysis and bio-informatics approaches to identify the relationship between light and temperature sensing pathways. The results of these works, combined with literature research results, shown that multiple hormone-synthesis and -transport genes respond to both light and temperature stimuli, and phytohormones shore up the relationship between light and temperature signaling transduction pathway.
