Given the rising frequency of thermal extremes (heatwaves and cold snaps) due to climate change, comprehending how a plant's origin affects its thermal tolerance breadth (TTB) becomes vital. We studied juvenile plants from three biomes: temperate coastal rainforest, desert and alpine. In controlled settings, plants underwent hot days and cold nights in a factorial design to examine thermal tolerance acclimation.

Convergent and parallel evolution occur more frequently than previously thought. Here, we focus on the evolutionary adaptations of angiosperms to sub-zero temperatures. We begin by introducing the research history of convergent and parallel evolution, defining all independent similarities as convergent evolution.

Temperature fluctuations challenge ectothermic species, particularly tropical fish dependent on external temperatures for physiological regulation. However, the molecular mechanisms through which low-temperature stress impacts immune responses in these species, especially in relation to chromatin accessibility and epigenetic regulation, remain poorly understood. In this study, we investigate chromatin and transcriptional changes in the head kidney and thymus tissues of Nile tilapia (Oreochromis niloticus), a tropical fish of significant economic importance, under cold stress.

Integration of resistance indicators, metabolomes, and transcriptomes to elucidate that there is a positive correlation between disease susceptibility and cold tolerance in tea plants. The flavonoid pathway was found to be the major metabolic and transcriptional enrichment pathway. A key domain NB-ARC was identified through joint analysis, along with analysis of key domains within the NB-ARC protein.
