Isolation and characterization of nine microsatellite markers for Brachypodium sylvaticum (Huds.) Beauv., a recently invasive grass species in Oregon.
The patterns of genetic diversity caused by rapid range expansions following recent colonizations are best observed using highly polymorphic genetic markers. We characterized nine microsatellite markers for Brachypodium sylvaticum, a bunchgrass invasive in the Northwestern United States and native to Eurasia. Loci exhibited from two to 10 alleles, and generally had high F(IS) values. These loci...
متن کاملIsolation and partial characterization of a lectin from a false brome grass (Brachypodium sylvaticum).
A lectin has been isolated from embryos of a false brome grass species (Brachypodium sylvaticum) by affinity chromatography on immobilized N-acetylglucosamine. It is a dimeric protein of two identical subunits of mol.wt. 18 000. Although it resembles cereal lectins with respect to its biochemical and physicochemical properties, it differs structurally in several aspects from wheat-germ-agglutin...
متن کاملEffects of choke disease in the grass Brachypodium phoenicoides
Epichloë species (Clavicipitaceae, Ascomycota) are the causal agents of choke disease of grasses. This disease is characterized by the presence of cylindrical fungal stromata which wrap the immature inflorescences and inhibit the normal development of reproductive tillers. Using phenotypic and molecular characters, as well as mating compatibility tests, the fungus causing choke disease in Brach...
متن کاملUse of Agrobacterium rhizogenes Strain 18r12v and Paromomycin Selection for Transformation of Brachypodium distachyon and Brachypodium sylvaticum
The genetic transformation of monocot grasses is a resource intensive process, the quality and efficiency of which is dependent in part upon the method of DNA introduction, as well as the ability to effectively separate transformed from wildtype tissue. Agrobacterium-mediated transformation of Brachypodium has relied mainly on Agrobacterium tumefaciens strain AGL1. Currently the antibiotic hygr...
متن کاملGrass cell wall feruloylation: distribution of bound ferulate and candidate gene expression in Brachypodium distachyon
The cell walls of grasses such as wheat, maize, rice, and sugar cane, contain large amounts of ferulate that is ester-linked to the cell wall polysaccharide glucuronoarabinoxylan (GAX). This ferulate is considered to limit the digestibility of polysaccharide in grass biomass as it forms covalent linkages between polysaccharide and lignin components. Candidate genes within a grass-specific clade...
