Changes in RCA and catalase proteins in response to heat stress.

<p>Proteins from the first supernatants (S) and last pellets (P) isolated from wild type (WT) and <i>chip</i>, <i>nbr1</i> and <i>rpn1a</i> mutants collected at indicated hours (h) under heat stress were subjected to SDS-PAGES and probed with anti-RCA (A) or anti-catalase (B) monoclonal antibody.
