Description | DMC1 protein is essential for catalyzing homologous renaturation and strand exchange events during homologous recombination mediated DNA repair. The catalytic reaction is coupled to ATP hydrolysis that determines the rates of the reaction system. It is expressed at the time of pollen (male) meiosis only. In RNAi experiments the pollen meiosis did not show any aberration from premeiotic interphase to middle zygotene stages. However meiotic process was affected from late zyogotene and pachytene stages onwards. Non-viable pollens were observed in RNAi lines leading to male sterility. |
