Expression analyses of meiotic and structural maintenance of chromosome genes in wild-type and mms21-1 flowers. Quantitative PCR was used to measure transcript levels of meiotic genes in buds RNA isolated from wild-type and mms21-1 mutant plants. (A) Expression analysis of select synapsis, recombination in wild-type and mms21-1 plants. (B) Expression analysis of select cohesin, condensin, SMC5/6 complex and SMC-like genes in wild-type and mms21-1 plants. Data presented here represent three biological replicate experiments. Each quantitative RT-PCR was repeated at least three times on each biological replicate. Bars are averages ± SE.
