Abstract
The expression profile of key carotenoid biosynthesis genes (ZmPSY1, ZmPSY2, ZmLcyE) was determined in the dynamics of cold stress and post-stress recovery in the leaves of Zea mays L. plants of four cold-resistant (breeders' data) inbred lines: L-5580-1, L-6097-1, L-5254-3 and L-5272-6. It has been shown that under normal growing conditions the expression level of all three genes in the L-5580-1 line is significantly higher compared to other lines. It was revealed that low-temperature exposure affects the trends of gene expression fluctuations in a similar way between the lines. It was determined that in the dynamics of stress, the leaves of L-5580-1 plants are characterized by coordination of the co-expression pattern of the ZmPSY1 and ZmPSY2 genes with changes in the carotenoid content.
