BRs (brassinosteroids), an endogenous hormone in plants, regulate cellulose accumulation, cell elongation and plant growth. Propiconazole (PCZ) is effective inhibitor of BR biosynthesis. DCB (2,6-Dichlorobenzonitrile) can inhibit the synthesis affects chemical composition walls. Celery one important leafy vegetable Apiaceae family with rich dietary fiber (including cellulose). The petioles leng...

We investigated the influence of different conditions (light composition and plant growth regulators (PGRs) in culture media) on morphophysiological parameters Stevia rebaudiana Bertoni vitro vivo. Both PGRs light spectra applied were found to significantly affect morphogenesis. During micropropagation stage S. rebaudiana, optimal growth, with a multiplication coefficient 15, was obtained an MS...

Seed germination and postgerminative growth are regulated by a delicate hormonal balance. Abscisic acid (ABA) represses Arabidopsis thaliana seed germination and postgerminative growth, while brassinosteroids (BRs) antagonize ABA-mediated inhibition and promote these processes. However, the molecular mechanism underlying BR-repressed ABA signaling remains largely unknown. Here, we show that the...
