旗叶衰老是小麦产量的重要决定因素，因为籽粒灌浆过程中叶片的衰老是协调发生的。然而，旗叶花后早期衰老的生物学过程尚不清楚。本研究利用高通量RNA测序技术研究了小麦的早期衰老。共鉴定出4887个差异表达基因（deg），任何表现出剧烈表达变化的基因都与特定的生物过程有关。层次聚类分析暗示NAC基因与旗叶花后衰老之间的潜在关系。此外，大量的基因与合成有关；运输;多种植物激素（JA， ABA， IAA， ET， SA， BR和CTK）的信号表达差异，并鉴定出许多与ABA和IAA相关的deg。研究结果揭示了旗叶早期衰老的分子过程，为今后提高小麦产量提供了有益的信息。
Flag leaf senescence is an important determinant of wheat yield, as leaf senescence occurs in a coordinated manner during grain filling. However, the biological process of early senescence of flag leaves post-anthesis is not clear. In this study, early senescence in wheat was investigated using a high-throughput RNA sequencing technique. A total of 4887 differentially expressed genes (DEGs) were identified, and any showing drastic expression changes were then linked to particular biological processes. A hierarchical cluster analysis implied potential relationships between NAC genes and post-anthesis senescence in the flag leaf. In addition, a large set of genes associated with the synthesis; transport; and signaling of multiple phytohormones (JA, ABA, IAA, ET, SA, BR, and CTK) were expressed differentially, and many DEGs related to ABA and IAA were identified. Our results provide insight into the molecular processes taking place during the early senescence of flag leaves, which may provide useful information in improving wheat yield in the future.
