These results demonstrate that RPN1a may be involved in trichome development through the GA and CK signaling pathways.
Title: RPN1a, a subunit of the 26S proteasome, controls trichome development in Arabidopsis.
Mutations in the Arabidopsis 26S proteasome regulatory subunit RPN1a suppressed edr2-associated phenotypes. the rpn1a mutant showed enhanced susceptibility to virulent and avirulent pathogens. RPN1a plays an important role in defense responses.
Title: RPN1a, a 26S proteasome subunit, is required for innate immunity in Arabidopsis.
Data indicate that overexpression of microtubule regulatory protein WDL3 (At3g23090) inhibited etiolated hypocotyl growth in regulatory particle non-ATPase subunit-1a mutant (rpn1a-4; At2g20580) plants but not in wild-type seedlings.
Title: Light-regulated hypocotyl elongation involves proteasome-dependent degradation of the microtubule regulatory protein WDL3 in Arabidopsis.
RPN1a is required for all developmental processes regulated by the 26SP, and it does not have a specific function in embryo development.
Title: The Arabidopsis 26S proteasome subunit RPN1a is required for optimal plant growth and stress responses.
RPN1 activity is essential during embryogenesis, where it might participate in the destruction of a specific set of protein substrates.[RPN1a]
Title: The RPN1 subunit of the 26S proteasome in Arabidopsis is essential for embryogenesis.
