ANALYSIS OF FLAVONOID-BIOSYNTHESIS GENE EXPRESSION IN THE FLOWERS OF MAJOR LILY CULTIVARS
Flavonoids biosynthesis pathway mostly determines the flower colour pheno-types in plants. This study was carried out to determine the presence and expression rates of the flavonoids biosynthesis-related genes in major lily cultivars. Primers of major colour genes were prepared by comparing the homologous genes of other species like sorghum, onion, and rice, and used for RT- PCR of eight lily cultivars. The results of transcriptional rate analyses showed that, in pink-flowering lily cultivars like, Pirax, red-flowering cultivar Atika, yellow-flowering cultivar Gironde, and white cultivar Siberia, all the genes tested were expressed. However, F3H and DFR genes were not expressed in yellow-flowering cultivar Yelloween. In white-flowering cultivars Samarinde Richmond and White Elegance, gene expressions varied among cultivars, especially in the genes CHS, F3H and ANS. We assume that the results on the presence and/or expression rates of the major flavonoid-biosynthesis genes shall be useful in the hybridization and transformation breeding in lilies for flower colour modification.
