Fig. 3From: 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 μmBack to article page
