<i>GmSAUR46b</i> Integrates Light Signals to Regulate Leaf Midrib Thickness and Stem Trichome Density in Soybean.

ABSTRACT: Soybean (Glycine max (L.) Merr.) is a vital crop for the global supply of protein and oil, with its growth and development being regulated by genetic, hormonal, and environmental factors, particularly light and hormone signaling. The Small Auxin-Up RNA (SAUR) gene family plays a crucial role in plant growth regulation; however, the molecular mechanisms by which GmSAUR46 integrates photosynthesis and hormonal networks in soybean remain unclear. In this study, we focused on GmSAUR46b (Glyma.19G182600.1) and employed CRISPR/Cas9-mediated knockout and 35S-driven overexpression lines, alongside wild-type soybean (cv. Williams 82), to investigate its function. RNA sequencing (RNA-Seq) was conducted on shoot apical meristems, stems, and leaves at three de
