| 초록 | Transcription factors play important role in many biological pathways including plant secondary metabolism. Floral scent is a complex trait of biological and applied significance. Flower volatiles are prominent for attract the visitors and pollinators to ensure the fertilization. Cymbidium Cultivar ‘Sael Bit’ flowers are highly fragrant and small size green and light yellow flowers. MYB (myeloblastosis) TFs play positive role in floral scent regulation. However, little is known about the MYB transcriptional regulation of floral scent biosynthesis. Due to importance of the plant biology we need to isolate the floral scent MYB TFs in this plant. In the present work, we isolated and cloned full length cDNA of Cymbidium Cultivar ‘Sael Bit’ MYB1 from the petal. MYB encodes 840bp open reading frame and 278 amino acids by functional characterization. In q-RT-PCR expression analysis MYB TF showed highest expression in petal and column compared to sepal and labellum. Petal is major source for scent production in many plants. Moreover this MYB gene expressed various flower developmental stages, which as highly expressed at initial flowering stage. The terpene synthase encoding myrcene synthase (MES), gene expressed through MYB TF regulation. According to these results we suggested that R2R3-MYB TF involved through regulation of terpenoid genes in floral scent profile. In further we will focus on regulation model through floral scent in Cymbidium Cultivar ‘Sael Bit’. | ||
