UgtP levels do not significantly affect cell length or diglucosyl-diacylglycerol levels in carbon-poor media. (a) Cell length distributions of strains BH736 (∆ugtP; P _xyl -ugtP-his) and BH12 (P _ugtP -ugtP-his; P _xyl -ugtP-his) cultured in minimal sorbitol ±0.5% xylose, determined by measuring the distance between the mid-points of adjacent cell wall septa (n = 600, error = SD). (b) Relative diglucosyl-diacylglycerol concentrations of lipid extracts from strains PL522 (WT), PL2102 (∆clpP), BH10 (P _xyl -ugtP-his), BH129 (P _xyl -ugtP-his; ∆clpP) cultured in minimal sorbitol, determined by thin layer chromatography and subsequent densitometric analysis of separated lipids (n = 3, error = SD)
