Quantitative trait loci (QTLs) affecting sugar composition
of the cell walls of maize (Zea mays) pericarp were
mapped as an approach to the identification of genes involved in cereal
wall biosynthesis. Mapping was performed using the IBM (B73 × Mo17) recombinant inbred line population. There were statistically
significant differences between B73 and Mo17 in content of xylose
(Xyl), arabinose (Ara), galactose (Gal), and glucose. Thirteen QTLs
were found, affecting the content of Xyl (two QTLs), Ara (two QTLs),
Gal (five QTLs), Glc (two QTLs), Ara + Gal (one QTL), and Xyl + Glc
(one QTL). The chromosomal regions corresponding to two of these,
affecting Ara + Gal and Ara on maize chromosome 3, could be aligned
with a syntenic region on rice (Oryza sativa)
chromosome 1, which has been completely sequenced and annotated. The
contiguous P1-derived artificial chromosome rice clones covering
the QTLs were predicted to encode 117 and 125 proteins, respectively.
Two of these genes encode putative glycosyltransferases, displaying
similarity to carbohydrate-active enzyme database family GT4
(galactosyltransferases) or to family GT64 (C-terminal domain of animal
heparan synthases). The results illustrate the potential of using
natural variation, emerging genomic resources, and homeology within the
Poaceae to identify candidate genes involved in the essential process
of cell wall biosynthesis.
