Fig. 6From: A small multigene hydroxyproline-O-galactosyltransferase family functions in arabinogalactan-protein glycosylation, growth and development in ArabidopsisRoot hair length and density reduced in the galt3, galt4, and galt6 mutants. a WT, galt1, galt3, galt4, and galt6 plants were grown on MS agar plates for 10 days. Bar = 1 mm. b Quantification of root hair length and c root hair density of the galt mutants. Asterisks indicate significantly reduced root hair length and density compared with WT controls according to Dunnett’s test (*P <0.05; **P <0.01; n >300)Back to article page
