From: Anther dehiscence is regulated by gibberellic acid in yellow lupine (Lupinus luteus L.)
A Rupture of the septum (Se) and stomium (St) cells in the first and second late anther developmental (LAD) stages of yellow lupine; C Progressive degeneration of septum cells in the first and third LAD stages. All transverse sections were stained with toluidine blue. Anthers were photographed by light microscopy. B, D Expression profile of LlQRT2 (QUARTET2) and LlPCS1 (PROMOTION OF CELL SURVIVAL1) in relation to LlACT (ACTIN) during different stages of LAD, as well as after GA3 application (LAD + GA3, 100 μM). P – pollen grain. 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 HSD test). Scale bars = 10 μm
