The moss Physcomitrella patens has recently emerged as a powerful genetically tractable model plant system. As a member of the bryophytes, P. patens provides a unique opportunity to study the evolution of a myriad of plant traits, such as polarized cell growth, gametophyte-to-sporophyte transitions, and sperm-to-pollen transition. The availability of a complete genome sequence, together with the ability to perform gene targeting efficiently in P. patens has spurred a flurry of elegant reverse genetic studies in this plant model that address a variety of key questions in plant developmental biology.
藓类植物拟南芥最近成为一种强大的、可遗传操作的模式植物系统。作为苔藓植物的一员，拟南芥为研究一系列植物特征的进化提供了独特的机会，例如极化细胞生长、配子体到孢子体的转变，以及精子到花粉的转变。完整基因组序列的可用性，以及在拟南芥中高效进行基因靶向的能力，激发了该植物模型的一系列优雅的反向遗传学研究，解决了植物发育生物学中的各种关键问题。
