| Title: The novel gene HOMOLOGOUS PAIRING ABERRATION IN RICE MEIOSIS1 of rice encodes a putative coiled-coil protein required for homologous chromosome pairing in meiosis .
| | Author: Nonomura K Nakano M Fukuda T Eiguchi M Miyao A Hirochika H Kurata N | | Journal: Plant Cell Citation: V : 16 ( 4 ) P : 1008-20 Year: 2004 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub15031413 Accession (PMID): 15031413 | Matching Sentences:
[ Sen. 1, subscore: 1.00 ]: We have identified and characterized a novel gene , PAIR1 ( HOMOLOGOUS PAIRING ABERRATION IN RICE MEIOSIS1 ) , required for homologous chromosome pairing and cytokinesis in male and female meiocytes of rice ( Oryza sativa ) .
[ Sen. 2, subscore: 1.00 ]: The pair1 mutation , tagged by the endogenous retrotransposon Tos17 , exhibited meiosis-specific defects and resulted in complete sterility in male and female gametes .
[ Sen. 3, subscore: 1.00 ]: The PAIR1 gene encodes a 492-amino acid protein , which contains putative coiled-coil motifs in the middle , two basic regions at both termini , and a potential nuclear localization signal at the C terminus .
[ Sen. 4, subscore: 1.00 ]: Expression of the PAIR1 gene was detected in the early stages of flower development , in which the majority of the sporocytes had not entered meiosis .
[ Sen. 5, subscore: 1.00 ]: During prophase I of the pair1 meiocyte , all the chromosomes became entangled to form a compact sphere adhered to a nucleolus , and homologous pairing failed .
[ Sen. 7, subscore: 1.00 ]: However , chromosomal fragmentation frequent in plant meiotic mutants was never observed in all of the pair1 meiocytes .
[ Sen. 8, subscore: 1.00 ]: These observations clarify that the PAIR1 protein plays an essential role in establishment of homologous chromosome pairing in rice meiosis .

| Title: The rice gene DEFECTIVE TAPETUM AND MEIOCYTES 1 ( DTM1 ) is required for early tapetum development and meiosis .
| | Author: Yi J Kim SR Lee DY Moon S Lee YS Jung KH Hwang I An G | | Journal: Plant J Citation: V : 70 P : 256-70 Year: 2012 Type: MEDLINE | | Literature: oryza Field: abstract Doc ID: pub22111585 Accession (PMID): 22111585 | Matching Sentences:
[ Sen. 7, subscore: 1.00 ]: Transcripts of UDT1 , which functions in tapetum development during early meiosis , were reduced in dtm1 anthers , as were those of PAIR1 , which is involved in chromosome pairing and synapsis during meiosis .
[ Sen. 9, subscore: 1.00 ]: Moreover , transcripts of DTM1 were reduced in msp1 mutant anthers , but not in udt1 and pair1 mutants .
[ Sen. 10, subscore: 1.00 ]: These results , together with their mutant phenotypes , suggest that DTM1 plays important roles in the ER membrane during early tapetum development , functioning after MSP1 and before UDT1 , and also in meiocyte development , after MEL1 and before PAIR1 .

[ Sen. 4, subscore: 1.00 ]: Known meiotic genes , including OsSPO11-1 , PAIR1 , PAIR2 , PAIR3 , OsDMC1 , OsMEL1 , OsRAD21-4 , OsSDS , and ZEP1 , all showed preferential expression in PMCs .
