Polysaccharides were extracted from wheat suspension culture and cultivated cells. Gaz-liquid chromatography of wheat suspension culture allowed identifying the composition of polysaccharides that were found to contain arabinose, xylose, galactose, glucose, and a little amount of mannose and rhamnose. In dried cultivated cells the polysaccharide structure consisted mainly from arabinose, xylose, and galactose. It was found that the percentage of the amount of monosaccharides was positively correlated with the concentration of 2,4-D at the suspension media.
Although there is low precipitation in Kazakhstan, rice is grown in regions serviced by irrigation canals. And breeding has begun in order to reduce the cost of importing glutinous rice. To develop glutinous rice cultivars efficiently, we need information on the haplotypes of Wx and Alk genes that affect eating quality. We investigated the haplotypes and amylopectin chain-length distribution in the first glutinous rice breeding lines developed in Kazakhstan. Such information could be useful to other countries starting glutinous rice breeding using parents possessing variation in Wx and Alk haplotypes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
