Characterization of a nitrogen-fixing bacterial strain from the roots of Digitaria sanguinalis
Canadian Journal of Microbiology, 1976Rates of nitrogen fixation of 3 to 10 g of N2 fixed per hectare per day were associated with root systems of Digitaria sanguinalis. A Gram-negative motile aerobic bacterial strain that was capable of N2 fixation was isolated from a washed root sample of one of these plants. Optimal growth and N2 fixation occurred at a pH of about 6.5, a temperature of

Omics analysis reveals key genes mediating herbicide resistance in Digitaria sanguinalis
Pesticide Biochemistry and PhysiologyDigitaria sanguinalis (L.) Scop is recognized as one of the most problematic agricultural weeds, with chemical control remaining a crucial management strategy. However, increased selection pressures have led to the emergence of resistant populations that reproduce and establish themselves as dominant communities, thereby severely jeopardizing crop ...

Postemergence Control of Large Crabgrass (Digitaria sanguinalis) with Herbicides
Weed Science, 1991Four field locations were used to compare environmental factors on efficacy of four postemergence grass herbicides in Kentucky bluegrass and bermudagrass turf. Imazaquin, BAS 514, and tridiphane were compared to fenoxaprop-ethyl, a registered herbicide, for postemergence control of large crabgrass.

AbstractUnderstanding host–pathogen evolutionary dynamics needs characterisation and quantification of processes occurring at many spatiotemporal scales. With this aim, the effects of smut on a naturally infected population of the summer annual Digitaria sanguinalis were followed for 4 years in an uncropped field.

Digitaria sanguinalis seedling development pattern: Relationship with seed origin
Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2013In the context of a long-term study of the pathosystem Digitaria sanguinalis–Ustilago syntherismae, seeds were collected over several years from a naturally infested field. Two different patterns of germination were found depending on the embryonic organ that first emerges: radicle or coleoptile. The mean frequencies of each pattern of germination were

Interaction of Bromoxynil and Postemergence Graminicides on Large Crabgrass (Digitaria sanguinalis)
Weed Technology, 1998The effect of bromoxynil on large crabgrass control by clethodim, sethoxydim, fluazifop-P, fluazifop-P plus fenoxaprop-P, and quizalofop-P was evaluated in 1996 and 1997 in bromoxynil-tolerant cotton and in fallow areas. Bromoxynil at 560 g ai/ha reduced large crabgrass control 4 weeks after treatment (WAT) when mixed with labeled rates of fluazifop-P,

Pesticide Biochemistry and Physiology
Weed resistance to a range of herbicides has rapidly evolved, often with different mechanisms of action. The resulting uninhibited growth of weeds poses demonstrable threats to crop production and sustainable agriculture. Digitaria sanguinalis (L.) Scop., a troublesome weed in corn and other agricultural fields, has developed resistance to herbicides ...

Transformation of Digitaria sanguinalis with XvPer1, a novel antioxidant
2002Digitaria sanguinalis, a widespread African grass, was micropropagated from immature inflorescences. Embryogenic calli generated was transformed with XvPerl using the Biolistic gene gun. XvPer 1 shares high similarity to a recently discovered group of antioxidants, the 1-Cys PRX's. A homologue was shown to be absent in D.
