Fig. 3From: Transcriptome analysis reveals the effect of grafting on gossypol biosynthesis and gland formation in cottonThe gland density in leaves of the high-gossypol cotton plants; A The gland density in different rootstocks and scion of the high-gossypol cotton, f1 is the scion of the ungrafted high-gossypol cotton. B The gland density in different rootstocks and scion of the high-gossypol cotton, f2 is the rootstock of the ungrafted high-gossypol cotton. Different letters indicate differences at P < 0.05, while uppercase letters indicate differences at P < 0.01Back to article page
