The Key Regulators and Metabolic Intermediates of Lignin Response to Low Temperatures Revealed by Transcript and Targeted Metabolic Profiling Analysis in Poplar

open access: yesAgronomy, 2022
Cold stress restricts the growth and development of plants. Lignin plays an important role in stress resistance. However, there are few studies on lignin mechanisms regulation under low-temperature stress. In this study, the contents of both acid-soluble

Cold Temperatures Fire up Circadian Neurons [PDF]

open access: yesCell Metabolism, 2018
Circadian clocks monitor both light and temperature cycles to entrain behavior and physiology to the environment. Recently in Nature, Yadlapalli et al. (2018) identified a subgroup of Drosophila clock neurons that responds to temperature input with changes in intracellular calcium and mediates effects of temperature on circadian entrainment and sleep.
