- Key message
- By differential screening of the library, we have isolated cDNAs of two genes, designated as Osc4 and Osc6, that are abundantly expressed in anthers containing tetrads and uninucleate microspores, but are not expressed in leaves or roots
- In situ localization of mRNA was carried out on two cDNAs (Osc4 and Osc6) that had been isolated from rice anthers at the microspore stage
- Expression of Osc4 is absent in mature anthers, while Osc6 is present although the expression decays during pollen maturation
- Connection
- OSC4, OsHUB1~MIP1, Histone H2B Monoubiquitination Mediated by OsHUB1 and OsHUB2 Is Involved in Anther Development by Regulating Tapetum Degradation Related Genes in Rice, Anther transcriptome analysis revealed that several key tapetum degradation-related genes including OsC4, OsCP1 and UDT1 were down-regulated in the mutants.

- OsABCG26, OSC4, An ABC transporter, OsABCG26, is required for anther cuticle and pollen exine formation and pollen-pistil interactions in rice, Expression of some key genes involved in lipid metabolism and transport, such as UDT1, WDA1, CYP704B2, OsABCG15, OsC4 and OsC6, was significantly altered in osabcg26 anther, possibly due to a disturbance in the homeostasis of anther lipid metabolism and transport
