Annotated Information
Function
Please input function information here. MICROSPORE AND TAPETUM REGULATOR1 (MTR1) is a rice fascilin glycoprotein protein. It may act as an extracellular adhesion molecule in male reproductive development by regulating the cell-to-cell communication between reproductive cells and their adjacent somatic cells.
- an essential gene for programmed tapetal cell fate and pollen formation in rice.
- is required for both the development of the diploid anther wall cells and maturation of the postmeiotic haploid microspores.
- effect the deposition of sporopollenin precursors on the surface.
Mutation and Phenotype
Please input Mutation and Phenotype information here.
mtr1 shows normal vegetative and nonreproductive floral organ development, but has smaller and pale-yellow anthers that fail to produce viable pollen grains.(A: wiletype; B: mtr1)
The result of (DAPI) stain show that start from stage 9 mtr1 microspores show slow development, did not seem to go through mitosis, and were eventually aborted. Transverse section analysis showe mtr1 anther wall layers were less degenerated than wild-type and microspores were collapsed.transmission electron microscopy (TEM) and scanning electron microscopy (SEM) of the anther show mtr1 tapetal cells were highly vacuolated and microspores were irregularly shaped with less deposition of sporopollenin precursors on the surface. And, at stage 7 and 8b, when wild-type tapetal cells showed TUNEL-positive nuclei. However, the mtr1 tapetal cells had no detectable TUNEL signals. Several rice tapetum-expressed genes, which are known to be involved in tapetal function and degeneration, displayed abnormal expression patterns in mtr1 .
