| contents | Beyond taxonomy: prospects for understanding morphological diversity in the grasses (Poaceae) Elizabeth A. Kellogg Biología Poaceae taxonomy phylogeny development gene expression The grass family (Poaceae) is unusually well known taxonomically, with over 10,000 describedspecies. These are characterized and classified according to a variety of morphological characters, particularthose of the inflorescence and the spikelet but also a wealth of micromorphological and molecularycharacters. Much data on the family is accessible electronically. Available phylogenies haveidentified 12 major lineages that are classified as subfamilies; within these subfamilies, especially forsubfamily Panicoideae, the phylogeny is becoming increasingly clear. Developmental studies focus onthe activity and fate of meristems throughout the plant, and illustrate how adult morphology arises.Analyses of quantitative trait loci (QTL) verify that some taxonomic characters are controlled by distinctgenes, thus supporting their use in taxonomy. Studies of gene expression identify several genes,including LEAFY HULL STERILE1 2006 artículo científico 0011-6793 https://www.redalyc.org/articulo.oa?id=66944101 en http://www.redalyc.org/revista.oa?id=669 Darwiniana application/pdf Instituto de Botánica Darwinion Darwiniana (Argentina) Num.1 Vol.44 |
