title: Screening of Arabidopsis thaliana stems for variation in cell wall polysaccharides.
abstract: A high-throughput method is described by which Arabidopsis thaliana stems can be screened for variation in cell wall composition after hydrolysis with Driselase or trifluoroacetic acid (TFA). Driselase, a mixture of fungal enzymes, hydrolyses cellulose (to glucose) and all the major matrix polysaccharides (to monosaccharides and/or characteristic disaccharides); TFA hydrolyses the matrix polysaccharides, but not cellulose, to monosaccharides. Two different wild-type ecotypes, Columbia and Wassilewskija, showed only minor differences in wall carbohydrate composition. A small number of T-DNA-tagged populations that were screened contained individuals in which the proportion of cellulose, xyloglucan or xylan differed quantitatively from the wild-type. Differences from the wild-type were also observed in the susceptibility of the hemicelluloses to hydrolysis by Driselase, probably reflecting differences in wall architecture.
