摘要
Global warming impacts crop production and threatens food security.Elevated temperatures are sensed by different cell components.Temperature increases are classified as either mild warm temperatures or excessively hot temperatures,which are perceived by distinct signaling pathways in plants.Warm temperatures induce thermomorphogenesis,while high-temperature stress triggers heat acclimation and has destructive effects on plant growth and development.In this review,we systematically summarize the heat-responsive genetic networks in Arabidopsis and crop plants based on recent studies.In addition,we highlight the strategies used to improve grain yield under heat stress from a source-sink perspective.We also discuss the remaining issues regarding the characteristics of thermosensors and the urgency required to explore the basis of acclimation under multifactorial stress combination.
