| General Description |
1.The mutant has an abnormal accumulation of unique sterol intermediates. 2.CPH is C-24 sterol methyltransferase. 3.The mutant plants display obvious cell expansion and division defects visible by light microscopy after the globular stage of embryogenesis. |
| Organ Specificity | |
| Impact on Wall | The mutant plants have incomplete cell walls and aberrant cell wall thickenings in embryonic and post-embryonic tissues. |
| Impact on Sugar Composition |
1. The mutant has ectopic callose and lignin deposits. 2. The mutant exhibits a deficiency in cellulose. |
