Sequence and expression variation in the dehydrin6 gene in barley varieties contrasting in response to drought stress

Furthermore, a multiple alignment of coding sequences of Dhn6 genes of the eight barley varieties was conducted. Two types of variation were observed in the UK varieties sequences; a deletion of 62 bp (segment ɸ) and six amino acid substitutions. Accordingly, we speculate that the observed variability in sequence and in expression of Dhn6 could be linked to the adaptability of barley to drought.
