| 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. |
