Ploidy: 2

Phenotype: Reduced cellulose content in roots and shoots; radial swelling of root tips and hypocotyls in plants grown at the restrictive temperature of 31C; small cotyledons and leaves with simpler shaped pavement cells, short bolts, more clustered flowers, abnormal floral morphology, smaller sepals and petals than wild type so that the pistil often protrudes beyond them when the stigma is receptive, distorted pistils; self pollination is rare because shortened stamen filaments placed the anther below the respective stigma and because anther dehiscence is impaired; pollen appears morphologically normal; seeds appear to develop normally if self pollination is assisted.
