Fig 8. CSN functions in the seed germination pathway.

Fig 8

A model indicating the targets of the CSN and CSN5A in the GA- and ABA- regulated seed germination pathway. The CSN complex (or CSN1) promotes germination by facilitating SCF-mediated degradation of RGL2 DELLA repressor. CSN5A, independently from the CSN complex, is involved in the turnover of ABI5, which acts downstream of RGL2. ABI5 appears to have a role in stabilizing RGL2, while RGL2 has been reported to activate ABI5 expression directly and by inducing ABA synthesis.
