Characterization of the termini of linear plasmids from Nectria haematococca...
SummaryThe mitochondria of isolate FS37 from Nectria haematococca mating population I (Fusarium solani f. sp. cucurbitae) contain two linear plasmids, pFSCI and pFSC2, of 9.2 and 8.3 kbp, respectively....
View ArticleEffect of chitinase antisense RNA expression on disease susceptibility of...
AbstractChitinases accumulate in higher plants upon pathogen attack are capable of hydrolyzing chitin-containing fungal cell walls and are thus implicated as part of the plant defense response to...
View ArticleStrain specificity in transformation of alfalfa by Agrobacterium tumefaciens
AbstractProduction of transgenic alfalfa plants by Agrobacterium-mediated transformation requires Agrobacterium infection and regeneration from tissue culture. Variation in alfalfa (Medicago sativa L.)...
View ArticleAlfalfa (Medicago sativa L.) resistance to the root-lesion nematode,...
AbstractAlfalfa (Medicago sativa) varieties with antibiosis-based resistance to the root-lesion nematode (Pratylenchus penetrans), a migratory endoparasite of many crops, have been developed by...

AbstractStrains of Streptomyces were tested for their ability to reduce population densities of the root-lesion nematode (RLN), Pratylenchus penetrans, in roots of alfalfa (Medicago sativa) in growth...
View ArticlePlant improvement for tolerance to aluminum in acid soils – a review
AbstractDevelopment of acid soils that limit crop production is an increasing problem worldwide. Many factors contribute to phytotoxicity of these soils, however, in acid soils with a high mineral...

AbstractThe activity of constitutive promoters was compared in transgenic alfalfa plants using two marker genes. Three promoters, the 35S promoter from cauliflower mosaic virus (CaMV), the cassava vein...
View ArticleTransgenic alfalfa secretes a fungal endochitinase protein to the rhizosphere
AbstractTransgenic plants containing a chimeric gene construct that facilitates the exudation of proteins from roots offer novel approaches for modification of the rhizosphere and production of...
View ArticleAlfalfa ( Medicago sativa L.)
SummaryA protocol for rapid, highly efficient transformation of alfalfa is described. Leaf explants from growth chamber-grown plants of a highly regenerable genotype are surface-sterilized, the margins...
View ArticleTranscriptome profiling identified novel genes associated with aluminum...
AbstractOligonucleotide microarrays corresponding to over 16,000 genes were used to analyze changes in transcript accumulation in root tips of the Al-sensitive Medicago truncatula cultivar Jemalong...

AbstractA floral organ mutant was observed in transgenic Medicago truncatula Gaertn. plants that had two separate stigmas borne on two separate styles that emerged from a single superior carpel...
View ArticlePhysiological and molecular characterization of aluminum resistance in...
AbstractBackgroundAluminum (Al) toxicity is an important factor limiting crop production on acid soils. However, little is known about the mechanisms by which legumes respond to and resist Al stress....
View ArticleMedicago truncatula as a Model for Dicot Cell Wall Development
AbstractWe have initiated a genome-wide transcript profiling study using the model legume Medicago truncatula to identify putative genes related to cell wall biosynthesis and regulatory function in...

AbstractBackground and aimsEnhanced aluminum (Al) resistance has been observed in dicots over-expressing enzymes involved in organic acid synthesis; however, this approach for improving Al resistance...
View ArticleEffect of wheel traffic and green manure treatments on forage yield and crown...
AbstractHarvesting alfalfa damages crowns and increases the opportunity for entry of pathogens. Incorporation of green manures into soil increases population density of streptomycetes with broad...
