Table I. Cell wall sugar composition of leaf blades and epidermal peels from csld1 mutant and nonmutant plants.

Alcohol-insoluble residues were prepared from both whole-leaf blade sections and isolated epidermal strips of greenhouse-grown plants identified as mutant or wild type by PCR of a segregating family. Analysis of noncellulosic cell wall sugars was done at the Complex Carbohydrate Research Center at the University of Georgia. Values for noncellulosic sugars are given as mol %, with se in parentheses. Cellulose content was estimated based on remaining weight after the hydrolysis of hemicelluloses and lignin. Cellulose content is given as weight percentage of alcohol-insoluble cell wall fraction, with se in parentheses. None of the differences between csld1 mutant and wild-type samples were statistically significant at P < 0.05 (n = 4 for each sample). nd, Not detected; nt, not tested.
