[Researches on the relative expression of HQT gene in different organs of Lonicera japonica].

To reveal the correlation between HQT gene and the biosynthesis of chlorogenic acid in Lonicera japonica. RT-PCR was used to measure the relative expression of HQT gene and reference gene Actin, and agarose gel electrophoresis was used to analyse the PCR results. The brightness of Actin gene strips of different organs was properly similar to each other,but the brightness of HQT gene strips was significantly different. HQT gene strips of alabastrum were the brightest,the brightness of HQT gene strip of leaves took the second place, and the brightness of HQT gene strips of stems was very faint. This result was in accordance with the content of chlorogenic acid in different organs of Lonicera japonica. The expression of HQT gene with the biosynthesis of chlorogenic acid has necessary relation with Lonicera japonica.
