Abstract
AbstractThe appropriate timing of the accumulation of biogenic amines is very important during cold acclimation due to their direct protective role and their involvement in the signaling processes. The time course of changes in the amount of six of them was compared during a 3-week acclimation period in a freezing tolerant and a sensitive genotype of rye, barley and wheat. In general, a greater and faster cold-induced increase in biogenic amine content was observed in the tolerant genotypes of the three species compared to the sensitive ones. This change was very quick in the case of putrescine, spermidine and cadaverine reaching a maximum after three days in the freezing-tolerant rye genotype. There was a continuous increase in the spermine and tyramine contents during the whole acclimation period in the tolerant wheat genotype while nearly constant levels were detected in the sensitive one. The amount of these two amines exhibited a positive correlation with the level of freezing tolerance in each of the five sampling points. Based on the correlations, a coordinated adjustment of the level of the six studied biogenic amines occurred during the acclimation period which could contribute to the efficient adaptation to cold. In addition, the earlier induction of the biogenic amine accumulation in the freezing tolerant genotypes may contribute to their better cold acclimation.
