She's the boss: signaling in pollen tube reception
چکیده انگلیسی

In angiosperms, the sperm cells are carried within the pollen tubes (male gametophytes) to the female gametophyte so that double fertilization can occur. The female gametophyte exerts control over the male, with specialized cells known as synergids guiding the pollen tubes and controlling their behavior when they enter the female gametophyte so that the sperm cells can be delivered to the egg and central cell. Upon pollen tube arrival at the ovule, signal transduction cascades mediated by receptor-like kinases are initiated in both the synergid and the tip of the pollen tube, leading to synergid cell death and pollen tube rupture. In this review, we discuss the role of these receptors and of newly discovered members of the pollen tube reception pathway.


► Synergid cells of the female gametophyte control pollen tube behavior.
► FERONIA, NORTIA, LORELEI, and ZmES4 are female components of PT reception.
► ANXUR1/2 and KZM4 are male components of PT reception.
