| Title: PAIR2 is essential for homologous chromosome synapsis in rice meiosis I | | Author: Nonomura K Nakano M Eiguchi M Suzuki T Kurata N | | Journal: J Cell . Sci . Citation: V : 119 ( Pt 2 ) P : 217-25 Year: 2006 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub16410547 Accession (PMID): 16410547 | Matching Sentences:
[ Sen. 1, subscore: 1.00 ]: The PAIR2 gene is required for homologous chromosome synapsis at meiosis I in rice ( Oryza sativa L ) and encodes a HORMA-domain protein that is homologous to Saccharomyces cerevisiae HOP1 and Arabidopsis ASY1 .
[ Sen. 2, subscore: 1.00 ]: Immunocytological and electron microscopic analyses indicate that PAIR2 proteins associate with axial elements ( AEs ) at leptotene and zygotene , and is removed from the AEs of arm regions when homologous chromosomes have been synapsed .
[ Sen. 3, subscore: 1.00 ]: Immunocytology against a centromeric histone H3 variant revealed that PAIR2 remains at centromeres until diakinesis , by which time the homologous centromeres had already been synapsed .
[ Sen. 5, subscore: 1.00 ]: In the pair2-null mutant , homologous chromosome synapsis is completely eliminated .
[ Sen. 6, subscore: 1.00 ]: This study provides the first description of AE-associated protein in monocot plants and indicates that PAIR2 plays an essential role in promoting homologous chromosome synapsis .
[ Sen. 7, subscore: 1.00 ]: However , PAIR2 does not play a role in AE formation , sister chromatid cohesion at centromeres or kinetochore assembly in meiosis I of rice .

| Title: An insertional mutation in the rice PAIR2 gene , the ortholog of Arabidopsis ASY1 , results in a defect in homologous chromosome pairing during meiosis .

[ Sen. 1, subscore: 1.00 ]: To elucidate the genetic system that establishes homologous chromosome pairing in monocot plants , we have isolated an asynaptic mutant of rice , designated pair2 ( homologous pairing aberration in rice meiosis 2 ) , in which 24 completely unpaired univalents are observed at pachytene and diakinesis .
[ Sen. 4, subscore: 1.00 ]: Mature PAIR2 mRNA and several splicing variants were found to be highly expressed in wild-type reproductive it issues , and lower expression was also detected in vegetative it issues .
[ Sen. 5, subscore: 1.00 ]: In situ hybridization and BrdU incorporation experiments revealed that PAIR2 expression is specifically enhanced in male and female meiocytes , but not in those at pre-meiotic S phase or in the pollen maturation stages .
[ Sen. 6, subscore: 1.00 ]: The results obtained in this study suggest that the PAIR2 gene is essential for homologous chromosome pairing in meiosis , as in the case of the genes ASY1 and HOP1 .
[ Sen. 7, subscore: 1.00 ]: The study also suggested the possibility that a highly homologous copy of the PAIR2 gene located on a different chromosome is in fact a pseudogene .

| Title: MER3 is required for normal meiotic crossover formation , but not for presynaptic alignment in rice .

[ Sen. 6, subscore: 3.00 ]: In addition , MER3 does not colocalize with PAIR2 at the beginning of prophase I , but locates on one end of PAIR2 fragments at later stages , whereas MER3 foci merely locate on one end of REC8 fragments when signals start to be seen in early prophase I The normal loading of PAIR2 and REC8 in mer3 implies that their loading is independent of MER3 .
[ Sen. 7, subscore: 2.00 ]: On the contrary , the absence of MER3 signal in pair2 mutants indicates that PAIR2 is essential for the loading and further function of MER3 .

[ Sen. 5, subscore: 2.00 ]: In addition , we showed that although PAIR3 was not required for the initial recruitment of PAIR2 , it was required for the proper association of PAIR2 with chromosomes .

[ Sen. 7, subscore: 1.00 ]: In the absence of OsAM1 , many other critical meiotic components , including PAIR2 , ZEP1 and OsMER3 , could not be correctly installed onto chromosomes .
[ Sen. 8, subscore: 1.00 ]: In contrast , in pair2 , Osmer3 and zep1 mutants , OsAM1 could be loaded normally , suggesting that OsAM1 plays a fundamental role in building the proper chromosome structure at the beginning of meiosis .

[ Sen. 6, subscore: 1.00 ]: Furthermore , fluorescent in situ hybridization experiments on Osrec8 meiocytes demonstrated that the mutation eliminated meiotic centromeric cohesion completely during prophase I and also led to the bipolar orientation of the kinetochores during the first meiotic division and accordingly resulted in premature separation of sister chromatid during meiosis I Immunolocalization analyses revealed that the loading of PAIR2 , PAIR3 , OsMER3 , and ZEP1 all depended on OsREC8 .
[ Sen. 7, subscore: 1.00 ]: By contrast , the presence of the OsREC8 signal in pair2 , pair3 , Osmer3 , and zep1 mutants indicated that the loading of OsREC8 did not rely on these four proteins .
