Abstract

Plant adaptations to several abiotic stresses are manifested in the synthesis and accumulation of biochemical components in the cytoplasm acting as osmoregulators. The paper makes a short review of recent researches on the contributions of proline and protein as indicators of resistance to several biotic (virus, fungus) and abiotic stresses (salinity, drought, heavy metals, mineral stress etc.). In all these stress situation there is an increase in the accumulation of proline in bean (Phaseolus vulgaris L.). The contribution of protein to resistance to these stresses is not well established in bean.
