Arabidopsis	At3g27730	DNA helicase required for crossover formation, complete synapsis of homologous chromosomes and bivalent formation during meiosis.	Two meiotic crossover classes cohabit in Arabidopsis: one is dependent on MER3,whereas the other one is not.; 2005; DOI: 10.1016/j.cub.2005.02.056; PMID: 15854901; https://pubmed.ncbi.nlm.nih.gov/15854901/ | The Arabidopsis ROCK-N-ROLLERS gene encodes a homolog of the yeast ATP-dependent DNA helicase MER3 and is required for normal meiotic crossover formation.; 2005; DOI: 10.1111/j.1365-313x.2005.02461.x; PMID: 16045469; https://pubmed.ncbi.nlm.nih.gov/16045469/
Rice	Os02g0617500	DNA helicase required for crossover formation, complete synapsis of homologous chromosomes and bivalent formation during meiosis.	MER3 is required for normal meiotic crossover formation, but not for presynaptic alignment in rice.; 2009; DOI: 10.1242/jcs.049080; PMID: 19470578; https://pubmed.ncbi.nlm.nih.gov/19470578/ | ZIP4 in homologous chromosome synapsis and crossover formation in rice meiosis.; 2012; DOI: 10.1242/jcs.090993; PMID: 22393242; https://pubmed.ncbi.nlm.nih.gov/22393242/
