From: Anther dehiscence is regulated by gibberellic acid in yellow lupine (Lupinus luteus L.)
A Localization of secondary thickening (SecThick) within endothecial cell walls of yellow lupine anthers. Transverse sections were stained with toluidine blue. Anthers were photographed by light microscopy. B The function of typical lignin (CAD, CINNAMYL ALCOHOL DEHYDROGENASE) and cellulose (IRX1/CesA8, IRREGULAR XYLEM1/Cellulose synthase A catalytic subunit 8; IRX6/COBL4, COBRA-like4; IRX8/GAUT12, GAlactUronosylTransferase12) biosynthesis-related genes [15, 18, 36, 37]. C Transcriptional activity of investigated genes (related to LlACT) during late anther development (LAD) and after gibberellic acid treatment (LAD + GA3, 100 μM). Data are the mean ± SE of three biological replicates, each with two technical replicates. Letters represent statistically significant differences at p < 0.05 (one-way ANOVA followed by Tukey’s honest significant difference test). Scale bars = 25 μm
