  1. aWSP indicates water soluble glucan polysaccharide
  2. bColumbia genetic background
  3. cWS genetic background
  4. dValues significantly different from wild type after adjustment for multiple comparisons. Any values not so noted were not significantly different from wild type.
  5. Units are mg/g FW. The values shown are the mean and standard deviation from four independent leaf extractions, each of which was assayed in duplicate. Abbreviations are as follows: LD: 16 h light/8 h dark long day diurnal cycle; SD: 8 h light/16 h dark short day diurnal cycle; ND: not determined.
