Abnormal 'wrinkled' cell walls and retarded development of transgenic Arabidopsis thaliana plants expressing endo-1,4-beta-glucanase (cell) antisense.

摘要: Transgenic Arabidopsis thaliana plants expressing cell antisense exhibit reduced levels of mRNA and protein compared with wild-type plants. The former display significant alterations in their phenotype. have shorter stems roots are mechanically weaker than counterparts. In plants, the wall structure is markedly disrupted: both fluorescent confocal microscopy scanning electron revealed `wrinkled' walls, thus indicating that CEL1 plays an important role relaxation during growth expansion. number xylem elements per bundle smaller wild-type. addition, interfascicular fibers significantly less lignified former. It suggested A. thaliana, abnormal deposition affected by depletion associated not only growth, but also differentiation process vascular supporting tissues.
