During Brassinosteroid (BR) signal transduction pathway two forms exist,1) In absence of Brassinolide2) In presence of Brassinolidea) BKI1 is phosphorylated and dissociates from the plasma membraneb) BRI1 phosphorylation, and promotes BRI1–BAK1 heterodimerization, bringing their cytoplasmic domains together for interaction, transphosphorylationc) BRI1 and BAK1 can form homodimers and both undergoes endocytosis and recyclingd) BIN2 kinases Phosphorylate transcriptional factor BES1 and BZR1 and these Phosphorylated proteins are shortlived and are degraded in the proteasomee) BSK proteins activate BSU1 phosphatase which dephosphorylated BIN2 is degraded by the proteasome systemf) In absence of BIN2, dephosphorylated transcriptional factor BES1 and BZR1 form heterodimers with different transcription factors and bind E-box sequences to activate genes.Find out the correct match with in absence and presence of BL in BRs signal transduction pathway -triyambak.org
