Drought-Induced Changes in Protein Patterns of <i>Brassica napus</i> var. <i>oleifera</i> Roots

Abstract

Drought-induced changes in two-dimensional silver stained protein patterns of Brassica napus L. var. oleifera M. root system were detected both at quantitative and qualitative levels. Particularly, 13 new polypep- tides of low molecular weight were evidenced in the drought-stressed tap root, 12 of which were also present in the short tuberized roots, a specific drought-induced root type. The reversibility of these modifications, ob- served after 3 days rehydration, suggests that they might be involved in drought tolerance.
