Cold acclimation transcriptome of Brachypodium distachyon exposed to diurnal-freezing

Study focuses on the transcriptional responses to diurnal-freezing that accompany cold acclimation in cereal model B. distachyon. Responses under diurnal-freezing transition from initial stress responses to resumed plant growth. Results highlight transcriptional memory events and a habituation response to cold stress, contributing to scientific understanding of plant adaptation to environmental change.

本研究聚焦于禾本科模式植物二穗短柄草（B. distachyon）中伴随冷驯化过程的昼夜冷冻（diurnal-freezing）转录响应。在昼夜冷冻胁迫下，植物的转录响应会从初始的胁迫应答阶段逐步过渡至恢复植株生长的状态。研究结果揭示了转录记忆（transcriptional memory）事件以及植物对冷胁迫的习服响应，为解析植物适应环境变化的科学机制提供了重要支撑。
