Abstract

Abstract: The infection types produced by seven different rust strains on genes from the L group of flax were recorded in two different genetic backgrounds at two continuous temperature regimes of 15 and 25 °C. In many comparisons, the rust reaction was not affected by the change of genetic background and temperature. In a few cases, plants heterozygous for one effective and one ineffective L gene exhibited less resistance than plants homozygous for the effective gene. The lower temperature reduced the level of expression of certain L genes in flax conferring resistance to rust, which is opposite to the trend usually observed with temperature sensitive genes in other host-parasite systems. Also, evidence was obtained that the higher temperature may affect the functioning of an inhibitor gene present in certain strains of flax rust.
