Gene Details:

• MSU gene ID: LOC_Os02g57520
• RAPdb gene ID: Os02g0820800
• Gene Symbol: PTC2
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• PTC2 showed persistent tapetal cells and abnormal pollen wall patterning including absent nexine, collapsed bacula and disordered tectum.
• The defective tapetal PCD phenotype of PTC2 was similar to that of a PCD delayed mutant, ptc1, in rice, while the abnormal pollen wall patterning resembled that of a pollen wall defective mutant, tek, in Arabidopsis thaliana.
• Based on these data, we propose a model explaining how PTC2 affects anther and pollen development.
• The characterization of PTC2 in tapetal PCD and pollen wall patterning expands our understanding of the regulatory network of male reproductive development in rice and will aid future breeding approaches.
• Levels of anther cutin monomers in PTC2 anthers were significantly reduced, as was expression of a series of lipid biosynthetic genes.
• PTC2 transcript and protein were shown to be present in the anther after meiosis, consistent with the observed phenotype.
