Effects of Downregulation of CCoAOMT Expression on Lignin Biosynthesis in Tobacco

<正> Antisense CCoAOMT cDNA of Chinese white poplar( Populus tomentosa) was transformed into tobacco W38 mediated by Agrobacterium tumefaciens. The results of PCR, PCR-Southern and Northern dot analysis indicated that the antisense CCoAOMT cDNA was integrated in the genome of the transgenic tobacco and expressed at transcriptional level. The basal stems of the 3-month-old transgenic plants growing in the
