A working model for the SlNOR and SlNOR-like1 mediated regulation of tomato pollen development. In detail, SlNOR and SlNOR-like1 positively regulate the ABCG transporter genes SlABCG8/9/23 for transporting sporopollenin precursor, the SlGRP92 gene for pollen exine formation, and the SlCER1 gene for the cuticular wax biosynthesis for pollen exine composition and stamen development. SlNOR and SlNOR-like1 double knockout mutant (nor/nor-like1) exhibit the pollen abortion resulted from the pollen wall collapse and hindered pollen transmission. Positive effects are indicated by arrows.
