Proteins in npRNP sediments from control (c),
pre-induced (p), stressed (s), and recovered (r) tomato cells. A,
Schematic representation of heat-stress treatment and isolation of
npRNPs. B, Coomassie blue staining of proteins isolated from different
cytoplasmic RNP sediments after SDS-PAGE. C, Immunoblots of RNP
sediments probed for HSP70, small HSPs, HsfA2, the proteasome C2
subunit, and tubulin, respectively.
