OsDMC1 is the rice homologue of the yeast DMC1 gene. Here, we analyzed the function of OsDMC1 in meiosis using an RNA interference approach. The OsDMC1–RNAi lines grew normally during their vegetative phase but showed spikelet and pollen sterility. The sterility phenotypes were associated with down-regulated OsDMC1 transcript and protein levels mediated by RNAi. Further cytological observations of male meiocytes revealed that knock-down of OsDMC1 led to defects in bivalent formation and… 
OsDMC1 Is Not Required for Homologous Pairing in Rice Meiosis1[OPEN]
TLDR
Results suggest that during meiosis, OsDMC1 is dispensable for homologous pairing in rice, which is quite different from the DMC1 homologs identified so far in other organisms.
Functional conservation of the meiotic genes SDS and RCK in male meiosis in the monocot rice
TLDR
The results suggest that the functions of SDS and RCK are likely conserved in flowering plants, because rice and Arabidopsis, respectively, are members of monocots and eudicots, two largest groups of flowering plants.
Mutation of the rice gene PAIR3 results in lack of bivalent formation in meiosis.
TLDR
The results suggest that PAIR3 plays a crucial role in homologous chromosome pairing and synapsis in meiosis, and is preferentially expressed in reproductive organs, especially in pollen mother cells and the ovule tissues during meiosis.
OsAM1 is required for leptotene-zygotene transition in rice
TLDR
In the absence of OsAM1, many other critical meiotic components, including PAIR2, ZEP1 and OsMER3, could not be correctly installed onto chromosomes, and in contrast, in pair2, Osmer3 and zep1 mutants, Os AM1 could be loaded normally, suggesting that OsAM 1 plays a fundamental role in building the proper chromosome structure at the beginning of meiosis.
The rice gene DEFECTIVE TAPETUM AND MEIOCYTES 1 (DTM1) is required for early tapetum development and meiosis.
TLDR
RNA in-situ hybridization analyses 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 after PAIR1.
Analysis of the impact of the absence of RAD51 strand exchange activity in Arabidopsis meiosis
TLDR
The results show no significant effect of the absence of RAD51 strand-exchange activity on meiotic crossing-over rates or patterns in different chromosomal regions or across the whole genome of Arabidopsis, strongly supporting the argument that DMC1 catalyses repair of all meiotic DNA breaks, not only non-sister cross-overs.
desynaptic5 carries a spontaneous semi-dominant mutation affecting Disrupted Meiotic cDNA 1 in barley
TLDR
An exonic insertion in the positional candidate ortholog of Disrupted Meiotic cDNA 1 (HvDMC1) on chromosome 5H of des5 is identified, indicating the value of non-knockout mutations for dissection of the control of recombination in the early stages of meiosis.
The dmc1 Mutant Allows an Insight Into the DNA Double-Strand Break Repair During Meiosis in Barley (Hordeum vulgare L.)
TLDR
The results indicated that DMC1 is required for the DSB repair, crossing-over and proper chromosome disjunction during meiosis in barley.
XRCC3 is essential for proper double-strand break repair and homologous recombination in rice meiosis.
TLDR
The results suggest that XRCC3 plays critical roles in both DSB repair and homologous chromosome recombination during rice meiosis.
University of Dundee desynaptic 5 carries a spontaneous semi-dominant mutation affecting Disrupted Meiotic cDNA 1 in barley
Despite conservation of the process of meiosis, recombination landscapes vary between species, with large genome grasses such as barley (Hordeum vulgare L.) exhibiting a pattern of recombination that

Isolation and characterization of OsDMC1, the rice homologue of the yeast DMC1 gene essential for meiosis
TLDR
Southern blot analyses revealed that OsDMC1 is one of two DMC1 homologues present in rice, and was expressed at high-levels in reproductive organs, low- levels in roots, and undetectable levels in leaves and seedlings.
The Rice OsRad21-4, an Orthologue of Yeast Rec8 Protein, is Required for Efficient Meiosis
TLDR
Observations suggest that OsRad21-4 is essential for efficient meiosis, and the identification revealed that the rice genome has 4 RAD21-like genes that share lower than 21% identity at polypeptide levels, and each is present as a single copy in this genome.
The Arabidopsis MALE MEIOCYTE DEATH1 gene encodes a PHD-finger protein that is required for male meiosis.
TLDR
The results suggest that MMD1 may be involved in the regulation of gene expression during meiosis and that the mmd1 mutation triggers cell death in male meiocytes.
Random Chromosome Segregation without Meiotic Arrest in Both Male and Female Meiocytes of a dmc1 Mutant of Arabidopsis
TLDR
The data demonstrate that AtDMC1 function is crucial for meiosis in Arabidopsis, and that meiosis can be completed in theArabidopsis dmc1 mutant, which is not the case for mouse or some yeast mutants.
The mouse RecA-like gene Dmc1 is required for homologous chromosome synapsis during meiosis.
TLDR
The mouse Dmc1 protein was detected in leptotene-to-zygotene spermatocytes, when homolog pairing likely initiates, and random spread of univalent axial elements without correct pairing between homologs was revealed.
The Arabidopsis AtRAD51 gene is dispensable for vegetative development but required for meiosis.
TLDR
It is suggested that RAD51 function is essential for chromosome pairing and synapsis at early stages in meiosis in Arabidopsis, and major aspects of meiotic recombination seem to be conserved between yeast and plants, especially the fact that chromosome Pairing and Synapsis depend on the function of SPO11 and RAD51.
Cell Biological Characterization of Male Meiosis and Pollen Development in Rice
TLDR
Multiple stages of male meiosis in rice are described in detail from analysis of rice chromosome spreading with staining of 4′,6-diamidino-2-phenylindole to facilitate studies of rice meiosis and pollen development using molecular genetic and cell biological approaches.
Two rice DMC1 genes are differentially expressed during meiosis and during haploid and diploid mitosis
TLDR
Cloned two rice homologues of yeast DMC1, a meiosis-specific gene required for recombination between homologous chromosomes, suggest that D MC1B, either alone or in combination with DMC2A, contributes to recombination during meiosis and during haploid and diploid mitosis.
Meiotic prophase arrest with failure of chromosome synapsis in mice deficient for Dmc1, a germline-specific RecA homolog.
TLDR
A null mutation is generated in the Dmc1 gene in mice and it is shown that homozygous mutant males and females are sterile with arrest of gametogenesis in the first meiotic prophase.
Isolation and characterisation of the RAD51 and DMC1 homologs from Arabidopsis thaliana
TLDR
The isolation of two genes belonging to the RAD51 and DMC1 families from Arabidopsis thaliana indicated that not only AtRAD51 but also AtDMC1 are regulated during the cell cycle, with S-phase-specific induction.
