General Description 1. rsh mutant is a germination-defective agravitropic mutant with severely defective root, shoot, and hypocotyl and a vitreous appearance throughout.
2. The rsh mutant is cytokinesis defective;it has abnormal cell shapes and the cell growth in rsh appears to be in random directions.
3. RSH encodes a hydroxyproline-rich glycoprote-type cell wall protein.
Organ Specificity 1. RSH gene product is localized to the cell wall.
2. RSH is expressed throughout the plant.
