ANALYSIS OF FLAVONOID-BIOSYNTHESIS GENE EXPRESSION IN THE FLOWERS OF MAJOR LILY CULTIVARS

J. Liu, Y.S. Ryu, B.J. Ahn
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, F3’H 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.
