摘　　要：In flowering plants,the two sperm cells are passive cargo transported into the ovule by pollen tubes (Zhang et al.,2017).Therefore,the precise guidance of pollen tubes is critical for successful double fertilization (Dresselhaus and Franklin-Tong,2013).A series of male-female interactions are required to guarantee the spatiotemporal regulation of pollen tube guidance because during growth,pollen tubes continuously interact with different female tissues (Zhong et al.,2017;Zhong and Qu,2019).In the past two decades,there has been tremendous progress in elucidating the molecular mechanisms of pollen tube guidance regulation,mostly using Arabidopsis thaliana as a model system (Johnson et al.,2019).
