Nuclear protein phosphatases with Kelch-repeat domains modulate the response to brassinosteroids in Arabidopsis

Article Abstract:

Bsu1-ID that encodes a nuclear-localized serine-threonone protein phosphatase with an N-terminal Kelch-repeat domain is identified as a dominant suppressor of bri1 in Arabidopsis. The findings indicate that BSE1 is subject to antagonistic phosphorylation and dephosphorylation reactions in the nucleus, which fine-tune the amplitude of the response to BL.

The geminivirus nuclear shuttle protein is a virulence factor that suppresses transmembrane receptor kinase activity

Article Abstract:

The characterization of new LRR-RLK family members as virulence targets of the geminivirus nuclear shuttle protein (NSP) is described. NSP interacts specifically with three LRR-/RLKs, NIK1, NIK2, and NIK3, through an 80-amino acid region that encompasses the kinase active site and A-loop.

The Arabidopsis det3 mutant reveals a central role for the vacuolar H(sup)+-ATPase in plant growth and development

Article Abstract:

Results demonstrate that in det3 mutant of Arabidopsis DET3 gene codes for subunit C of the vacuolar ATPase. Data further reveal that alteration in the assembly of this ATPase affects hypocotyl elongation indicating that ATPase controls cell elongation and meristem activity.
