Název v původním jazyce

The use of dehydrin 5 in screening for frost tolerance in barley (Hordeum vulgare)

Popis výsledku v původním jazyce

The article discusses the possibility of the use of dehydrin 5 protein (DHN5) accumulation as a selection marker for frost tolerance (FT) in barley. Young barley plants of 21 cultivars of three growth habits (intermediate, winter, spring) were exposed tocold acclimation (CA) under neutral (12 h) photoperiod. DHN5 accumulation was determined by immunoblots and the acquired level of FT was evaluated by direct frost tests. CA led to the induction of DHN5 accumulation and to the increase in FT in all cultivars examined; however, differences in the rate of DHN5 and FT increase between the growth habits occured. After three weeks of CA, a positive linear correlation between the amount of accumulated DHN5 and the acquired level of FT was found, but only whenthe cultivars with contrasting levels of FT (intermediate and winter cultivars versus spring ones) were used for evaluation.
