| Abstract |
Programmed cell death (PCD) was induced by the Yariv reagent in Nicotiana tabacum cv. Bright Yellow-2 cell suspension. The analyses of proteins extracts by 2-D electrophoresis clearly show massive protein degradation which was mainly due to cysteine protease activity. In contrast, some proteins remained unchanged up to 72 h after PCD induction. Peptide mass fingerprints of these proteins, obtained by MALDI-TOF, identified calreticulin, heat shock protein (HSP) 60, HSP70, malate dehydrogenase and mitochondrial ATP synthase beta-subunit. |
