Abstract: | Cell wall is a key structure of the plant organism engaged in numerous functions, and plants spend enormous resources on cell wall formation. Cell wall components are the most widespread organic substances on the Earth. However important is assembling plant cell wall polysaccharides, this process has been insufficiently studied by the methods of molecular genetics; in particular, too little is known of the genes that code for the relevant enzymes (glycosyltransferases, GT). The review addresses the current situation by expounding on GT classification, describing the characteristics of enzymes that synthesize cell wall polysaccharides, and summing up the existing knowledge of already identified and putative cellulose and callose synthases and GT localized in the Golgi apparatus. The methodology for searching and characterizing new genes that participate in cell wall formation is under discussion.__________Translated from Fiziologiya Rastenii, Vol. 52, No. 3, 2005, pp. 443–462.Original Russian Text Copyright © 2005 by Gorshkova, Nikolovski, Finaev. |
