From: Characterization of the Gh4CL gene family reveals a role of Gh4CL7 in drought tolerance
Analyses of lignin contents and the expression level of genes related to lignin biosynthesis. a-b Comparison of lignin contents in Gh4CL7-OE Arabidopsis plants (a) and in Gh4CL7-silencing cotton plants (b). c Stem sections from the TRV:Gh4CL7 and TRV:00 cotton plants stained with phloroglucinol-HCl. d The relative expression levels of genes related to lignin biosynthesis. Data were represented as the mean ± SE of three biological replicates; asterisks indicate levels of significance based on t-test (* P < 0.05, ** P < 0.01)
