Abstract
Photoperiod sensitivity is crucial for soybean flowering, adaptation, and yield. In soybean, photoperiod sensitivity centers around the evening complex (EC) that regulates the transcriptional level of the core transcription factor E1, thereby regulating flowering. However, little is known about the regulation of the activity of EC. Our study identifies how E2/GIGANTEA (GI) and its homologs modulate photoperiod sensitivity through interactions with the EC. During long days, E2 interacts with the blue-light receptor flavin-binding, kelch repeat, F box 1 (FKF1), leading to the degradation of J/ELF3, an EC component. EC also suppresses E2 expression by binding to its promoter. This interplay forms a photoperiod regulatory loop, maintaining sensitivity to photoperiod. Disruption of this loop leads to losing sensitivity, affecting soybean’s adaptability and yield. Understanding this loop’s dynamics is vital for molecular breeding to reduce soybean’s photoperiod sensitivity and develop cultivars with better adaptability and higher yields, potentially leading to the creation of photoperiod-insensitive varieties for broader agricultural applications.
期刊介绍:
Developmental Cell, established in 2001, is a comprehensive journal that explores a wide range of topics in cell and developmental biology. Our publication encompasses work across various disciplines within biology, with a particular emphasis on investigating the intersections between cell biology, developmental biology, and other related fields. Our primary objective is to present research conducted through a cell biological perspective, addressing the essential mechanisms governing cell function, cellular interactions, and responses to the environment. Moreover, we focus on understanding the collective behavior of cells, culminating in the formation of tissues, organs, and whole organisms, while also investigating the consequences of any malfunctions in these intricate processes.
