发育阶段之间的过渡时间是植物形态的关键决定因素。在藓类小立碗藓中，从原丝体到配子体的转变是一个特别重要的步骤，因为它导致植物体从二维到三维生长的变化。细胞分裂素（CK）促进了这一转变，但其机制尚不清楚。此前有报道称，P.叶柄上叶片（BOP）基因（PpBOP）的专利同源物在CK下游起作用以促进向配子体的转变。为了进一步了解PpBOP在控制这种转变中的作用，我们对PpBOP基因进行了功能分析。我们同时破坏了P中所有三个PpBOP基因的功能。然而，在使用CRISPR技术的专利中，在配子体或孢子体生长阶段期间在三重突变体中没有观察到异常表型。CK处理没有改变三突变体的相变。我们认为PpBOP基因在控制P.在正常条件下的专利开发。我们认为，BOP基因不参与控制发育过程中的brabetes和其他基底土地植物，但可能在生理过程中发挥作用，如在防御反应。
The timing of the transition between developmental phases is a critical determinant of plant form. In the mossPhyscomitrella patens, the transition from protonema to gametophore is a particularly important step as it results in a change from two-dimensional to three-dimensional growth of the plant body. It is well known that this transition is promoted by cytokinin (CK), however, the underlying mechanisms are poorly understood. Previously, it was reported thatP. patensorthologs ofBLADE-ON-PETIOLE(BOP) genes (PpBOPs) work downstream of CK to promote the transition to gametophore. To further understand the role ofPpBOPs in the control of this transition, we performed functional analyses ofPpBOPgenes. We simultaneously disrupted the function of all threePpBOPgenes inP. patensusing CRISPR technology, however, no abnormal phenotypes were observed in the triple mutant during either the gametophytic or the sporophytic growth stages. CK treatment did not alter the phase change in the triple mutant. We conclude thatPpBOPgenes are unnecessary in the control ofP. patensdevelopment under normal conditions. We propose thatBOPgenes are not involved in the control of developmental processes in bryophytes and other basal land plants, but may function in physiological processes such as in the defense response.
