Regulation of tillering in sorghum: environmental effects.

abstract：BACKGROUND AND AIMS:Covalent linkages between xyloglucan and rhamnogalacturonan-I (RG-I) have been reported in the primary cell walls of cultured Rosa cells and may contribute to wall architecture. This study investigated whether this chemical feature is general to angiosperms or whether Rosa is unusual. * METHODS:Xyl...
