title: Genome reprogramming and small interfering RNA in the Arabidopsis germline.
abstract: The movement of mobile small RNA signals between cells has garnered much interest over the last few years, and has recently been extended to germ cells during gamete development. Focusing on plants, we review mobile RNA signals that arise following reprogramming in the germline, and their effect on transposable element silencing on the one hand and on meiotic and apomictic germ cell fate on the other. A potential role for reprogramming and small RNA in hybrid formation and speciation is proposed.
