Abstract

In the course of the experiments, studies were made on the effect of low temperature on rRNA processing. The two wheat lines in this work differed from each other only as regards frost resistance. It was proved that in the case of the weakly frost resistant line quantitative and qualitative changes took place in the rRNA maturation process as the result of low temperature. During cold treatment the last precursors (1.4 and 0.9 MD) of the two stable cytoplasmic rRNAs (1.3 and 0.7 MD) accumulated at the expense of the stable rRNA fractions. This accumulation increased as cold treatment proceeded. In the line with good frost resistance this change could not be demonstrated. The results indicate that in the poorly resistant line the cold treatment had an inhibitory effect on the last step in the maturation process, i.e. at low temper attire this process is unable to proceed to completion.
