  • Key message
    • The pollen grains of dcm1 are proved to be defective in exine formation
    • Furthermore, peripheral callose surrounding the dcm1 pollen mother cells (PMCs) also disappeared untimely around pachytene
    • The zinc finger protein DCM1 is required for male meiotic cytokinesis by preserving callose in rice.
    • We demonstrated that meiotic cytokinesis defect in dcm1 is caused by prematurely dissolution of callosic plates
    • Together, we propose that DCM1 plays an essential role in male meiotic cytokinesis by preserving callose from prematurely dissolution in rice
