LITERATURE
in developing barley endosperm, isoform UXE3 mRNA levels peak at a time when UDP-alpha-D-xylopyranose synthase transcripts also reach a maximum and when arabinoxylan biosynthesis is initiated
in developing barley endosperm, isoforms UXE1 mRNA levels peak at a time when UDP-alpha-D-xylopyranose synthase transcripts also reach a maximum and when arabinoxylan biosynthesis is initiated. Transcript levels for the UXE1 gene are about 4fold higher at 9 days after pollination than in the syncytial and cellularization stages
isoform UXE2 transcript abundance is moderate during the syncytial stage of endosperm development (2-6 days after pollination) but decreases to undetectable levels beyond 6 days after pollination
