#Unit 6. System Physiology – Plant

In the presence of brassinolide, the activated phosphatase BSU1 dephosphorylates BIN2 and promotes its degradation by the 26S proteasome system, thus blocking its activity. BES1 and BZR1

are then dephosphorylated by PROTEIN PHOSPHATASE2A

(PP2A), and the active forms of BES1 and BZR1 move into the nucleus where they regulate the expression of brassinolide response genes

Parity rules were given by Erwin Chargaff

I. Rule of complementarity 

II. Rule of Equal amount applies more closely to introns than to exons

III. Cluster rule – Purines in nontemplate strand applies more closely to Exons
