Fig. 4From: The diurnal emission of floral scent in Oncidium hybrid orchid is controlled by CIRCADIAN CLOCK ASSOCIATED 1 (CCA1) through the direct regulation on terpene synthaseThe primary structure analysis showing cis-acting elements in TPS promoter region (~ 1375 bp length). The putative CCA1 binding site (CBS), -AGATTTTT- located at -423 ~ -430 bp of TPS promoter was marked by red colorBack to article page
