Accumulation of Dehydrins and ABA-Inducible Proteins in Wheat Seedlings during Low-Temperature Acclimation

Accumulation of Dehydrins and ABA-Inducible Proteins in Wheat Seedlings during Low-Temperature... Using one-dimensional SDS-PAGE and immunochemical methods, we detected the presence and estimated the content of dehydrins and ABA-inducible (RAB) polypeptides in etiolated seedlings of four spring and three winter wheat (Triticum aestivum L.) cultivars differing in frost hardiness. We hardened three-day-old seedlings at 4°C for nine days or grew them at 22°C for a day (control seedlings). We established that heat-stable cold-regulated (COR) polypeptides with mol wts of 209, 196, 169, 66, 50, and 41 kD, which are characteristic of hardened wheat seedlings, were homologous to polypeptides from a dehydrin family and polypeptides with mol wts of 209, 196, 66, 50, and 41 kD were immunologically related to RAB-proteins. We supposed that these COR polypeptides were involved in the prevention of local protein dehydration and denaturation during hypothermia. Analysis of the relative content of COR proteins revealed a close correlation between the cultivar frost hardiness and the concentration of these proteins. It seems evident that different accumulation of dehydrins and RAB polypeptides in different cultivars of a single species is one of the causes for different plant frost hardiness.
