Abstract

Cellulose, an abundant, crystalline polysaccharide, is central to plant morphogenesis and to many industries. Chemical and ultrastructural analyses together with map-based cloning indicate that the RSW1 locus of Arabidopsis encodes the catalytic subunit of cellulose synthase. The cloned gene complements the rsw1 mutant whose temperature-sensitive allele is changed in one amino acid. The mutant allele causes a specific reduction in cellulose synthesis, accumulation of noncrystalline β-1,4-glucan, disassembly of cellulose synthase, and widespread morphological abnormalities. Microfibril crystallization may require proper assembly of the RSW1 gene product into synthase complexes whereas glucan biosynthesis per se does not.

Glucan was extracted with ammonium oxalate from three separate batches of rsw1 purified in the supernatant after precipitation of pectins overnight with 2% cetyltrimethylammonium bromide. Glucose in trifluoroacetic acid hydrolysates was quantified against inositol internal standard by gas chromatography electron-impact–mass spectrometry (GC-MS) (Fisons MD800) of alditol acetates [
