Abstract

Cold acclimation in plants involves the expression of many genes and gene families. The present study reports the expression analysis of three members of the blt14 gene family in barley. Gene-specific antisense oligonucleotides were used as probes in northern experiments so as to follow independently the expression of individual members of the gene family. Each clone revealed different accumulation kinetics when a spring and a winter cultivar were compared, suggesting that the different regulatory mechanisms leading to mRNA accumulation of an individual member of the blt14 gene family are genotype-dependent. In a collection of Hordeum spontaneum genotypes both qualitative and quantitative polymorphisms were found for the accumulation of blt14-related mRNAs, although no clear relationships were found between blt14 expression and frost resistance.
