摘　　要：Given the increase in global climate change,reconciling the increasing demand for food production with dwindling water resources poses a formidable challenge.To ensure sustainable rice production and global food security,a thorough exploration of the genetic mechanism that underlies the delicate balance between growth and drought tolerance in rice is imperative.The sessile nature of plants has driven their adaptive evolution,enabling them to regulate gene expression and exhibit physiological and developmental plasticity in response to environmental changes[1].Alternative splicing(AS),a prevalent phenomenon in plants,plays a crucial role in the regulation of posttranscriptional gene expression[2].AS serves as an essential mechanism involved in both developmental processes and stress responses[3–5].
