Genbank accession number
- Key message
- Map-based cloning demonstrated that TIP3 encodes a conserved PHD-finger protein and further study confirmed TIP3 functioned as a transcription factor with transcriptional activation activity
- The tip3 mutant displayed smaller and pale yellow anthers without mature pollen grains, abnormal Ubisch body morphology, no pollen wall formation as well as delayed tapetum degeneration
- Moreover, TIP3 can physically interact with TDR which is a key component of the transcriptional cascade in regulating tapetum development and pollen wall formation
- Taken together, our results reveal an unprecedented role of TIP3 in regulating Ubisch bodies and pollen exine formation, which presents a potential tool to manipulate male fertility for hybrid rice breeding
- TIP3 is preferentially expressed in the tapetum and microspores during anther development
- Furthermore, disruption of TIP3 changed the expression of several genes involved in tapetum development and degradation, biosynthesis and transport of lipid monomers of sporopollenin in tip3 mutant
- Connection
- TDR, TIP3, TDR INTERACTING PROTEIN 3 encoding a PHD-finger transcription factor regulates Ubisch bodies and pollen wall formation in rice., Here, we characterized and isolated a male sterility mutant of TDR INTERACTION PROTEIN 3 (TIP3) in rice
- TDR, TIP3, TDR INTERACTING PROTEIN 3 encoding a PHD-finger transcription factor regulates Ubisch bodies and pollen wall formation in rice., Moreover, TIP3 can physically interact with TDR which is a key component of the transcriptional cascade in regulating tapetum development and pollen wall formation
- OsMYB80~BM1, TIP3, The MYB transcription factor Baymax1 plays a critical role in rice male fertility, BM1 can physically interacts with bHLH protein TIP2, EAT1, and PHD (plant homeodomain)-finger member TIP3, respectively
