[Prokaryotic expression and in vitro enzyme activity analysis of flavonol synthase in Chrysanthemum morifolium cv. 'Hangju'].

We cloned flavonol synthase gene (named as CmFLS) by RACE from Chrysanthemum morifolium cv. 'Hangju' based on transcriptome database. Sequencing results showed that 1 235 bp sequence was acquired with the largest open reading frame (ORF) of 1 008 bp, which encoded 335 amino acids.

[Cloning and expression analysis of and quantification of downstream products in under flooding stress].

To investigate the effects of the expression of flavonoid 3' hydroxylase gene ( and active ingredients in under flooding stress, we cloned F3'H from Hangju (temporarily named ) and conducted bioinformatics analysis. During the flower bud differentiation stage, we flooded the and then used the Real-time PCR to detect the relative expression of ; Finally, active ingredients of the inflorescence were measured by HPLC.The sequencing results showed that 1 562 bp sequence was acquired with the largest open reading frame of 1 527 bp, which encoded 508 amino acids.
