Rice anther development relatedproteins identified in ubiquitinome.

MSU ID	Gene name	Protein ID	Modified sequence	Function in anther development	Ref.
LOC_Os01g68870	MSP1	B8A868	_ATENFSK(gl)VHIIGDGGFGTVYK_	The msp1 mutation results in an excessive number of male sporocytes, the disorganized formation of anther wall layers, and the loss of tapetum layer.	[52]
LOC_Os07g41360	UAM3	B8B8B1	_ASCISFK(gl)DSACR_	UAM3 knockdown transformants have abnormal pollen cell wall and exine.	[53]
LOC_Os10g33250	WDA1	B8BHF1	_VTMTNK(gl)QDYHLLKPEIPETVADNLSFSK_	The wda1 mutant shows defects in the biosynthesis of very-long-chain fatty acids and pollen exine formation.	[54]
LOC_Os08g41950	OsMADS7	P0C5B0	_YQK(gl)CSYAGPETAVQNR_	The OsMADS7 and OsMADS8 knockdown transformants show thin anthers and other severe phenotypes.	[55]
LOC_Os03g19520	NRL2	A2XFV6	_HLDHK(gl)NVLYDPQIK_	The nrl2 mutant shows abnormal tapetum degeneration and microspore development, and other severe phenotypes.	[56]
LOC_Os01g56330	OsDRUS2	B8ANY8	_TTNILLDEK(gl)WVAK_ _GLHYLHTGAK(gl)HTIIHR_ _K(gl)GILDQIVDPHLK_ _PALNPTLAK(gl)EEVSLAEWALHCQK_ _EHLYK(gl)TQNAPLSWR_	The DRUS1 and DRUS2 are two closely related receptor-like kinases. The drus1-1 drus2 double knockout mutant shows extreme dwarfism and sterile spikelets.	[57]
LOC_Os03g21540	OsDRUS1	B8ANY8	_TTNILLDEK(gl)WVAK_ _GLHYLHTGAK(gl)HTIIHR_ _K(gl)GILDQIVDPHLK_ _PALNPTLAK(gl)EEVSLAEWALHCQK_
