The Arabidopsis 26S proteasome subunit RPN1a is required for optimal plant growth and stress responses.

Plant & cell physiology - 1 Sept 2009

Wang Songhu, Kurepa Jasmina, Smalle Jan A

Abstract excerpt

The current literature offers contradictory results regarding the role of the proteasome subunit RPN1a in Arabidopsis development. Here we show that plants lacking RPN1a are viable and have increased cell sizes, decreased heat shock tolerance, increased oxidative stress tolerance and other phenotypes characteristic for 26S proteasome subunit mutants. These results strengthen our contention that most of the...
