[The frequencies of the low-molecular-weight alanine-rich cold shock proteins genes and variation of their primary structure in plants of temperate climate].

Polymerase chain reaction (PCR) was used to study the frequencies of the gene of a low-molecular-weight alanine-rich cold shock protein in plants of temperate climate. This gene was demonstrated to be specific for the family Cruciferae. Its variability in this family was studied.
