Quatrano RS, McDaniel SF, Khandelwal A, Perroud PF, Cove DJ: Physcomitrella patens: mosses enter the genomic age. Curr Opin Plant Biol. 2007 Apr;10(2):182-9. Epub 2007 Feb 8.
The sequenced genome of the moss Physcomitrella patens provides a powerful tool for comparative analyses of land plant genomes. In parallel, several tools for studying gene function have been developed in P. patens, including RNA interference, inducible promoters and gene targeting, a unique attribute of this plant system. The results of these initiatives are now being realized. For example, transcriptomic analyses illustrate commonalities among plant lineages in gene content, structure, and regulation. Transgenic studies show that the regulatory factors ABSCISIC ACID INSENSITIVE3 (ABI3) and LEAFY (LFY) have molecular functions that are conserved between moss and angiosperms, in spite of the fact that they function in non-homologous tissues. Future work in P. patens will contribute to our understanding of the molecular basis of plant development and evolution. |
