Scheme of pathways for matrix polysaccharide precursors. Bar charts represent relative metabolites levels and relative transcripts levels of enzymes involved in sugar-nucleotide interconversation in developing fibers between Li
NILs. Error bars indicate standard deviation from three biological replicates. Asterisks represent significant difference between lines. Abbreviations: PGI, phosphoglucose isomerase; PGM, phosphoglucomutase; UGP, UDP-D-glucose pyrophosphorylase; UDP-GclA-4-Ep, UDP-glucuronic acid 4-epimerase; Fructose-6-P, fructose-6-phosphate; Glucose-6-P, glucose-6-phosphate; Glc-1-P, glucose-1-phosphate; UDP-Glc, UDP-glucose; UDP-GlcA, UDP-glucuronic acid; UDP-GalA, UDP-galacturonic acid; UDP-Xyl, UDP-xylose; UDP-Ara, UDP-arabinose; and UDP-Api, UDP-apiose.
