Abstract: | Background Guar, Cyamopsis tetragonoloba (L.) Taub, is a member of the Leguminosae (Fabaceae) family and is economically the most important of the four species in the genus. The endosperm of guar seed is a rich source
of mucilage or gum, which forms a viscous gel in cold water, and is used as an emulsifier, thickener and stabilizer in a wide
range of foods and industrial applications. Guar gum is a galactomannan, consisting of a linear (1→4)-β-linked D-mannan backbone
with single-unit, (1→6)-linked, α-D-galactopyranosyl side chains. To better understand regulation of guar seed development
and galactomannan metabolism we created cDNA libraries and a resulting EST dataset from different developmental stages of
guar seeds. |
