Abstract/Contents: | Provides an in-depth discussion of gene mapping within grasses, including the following topics: definitions of macrocolinearity and synteny; microcolinearity; the importance of synteny among the grasses; the case of the gibberellic acid-insensitive (GAI) dwarves in plants: toward mapping in silico; on using "family" rather than "species" as a model genetic system; convergence in a phylogenetic tree marks an experimental oppportunity; the grass hybrids database: http://128.32.88.35/GRASSWEB/; really wide crosses between grasses: chromosome addition lines; the consequences of rounds and rounds of duplications and breakpoints: the importance of consolidation of chromosomes before colinearity comparisons; and the mechanical basis for Darwinian evolution. Concludes that "most data support and notes refute the general conclusion that grasses share 'alleles' of the ancestral grass genome rearranged in blocks that remain long enough to reconstruct, by the process of consolidation, useful syntenic relationships." Also notes that "it would be ironic to say the least if our most specialized and vulnerable wild species become extinct before we are able to understand and value their alleles." |
