The nucleotide sequence of a geminivirus from Digitaria sanguinalis

Virology, 1987
The encapsidated single-stranded circular DNA of a geminivirus isolated from Digitaria sanguinalis has been sequenced. The data obtained are consistent with there being one DNA circle of 2701 nucleotides. Comparison of the nucleotide sequence with those of maize streak virus (MSV) and wheat dwarf virus showed 64 and 47% DNA homology, respectively.

A Geminivirus, Serologically Related to Maize Streak Virus, from Digitaria sanguinalis from Vanuatu

Journal of General Virology, 1986
SUMMARY Electron microscopy of purified particles of a virus found in Dig#aria sanguinalis from Vanuatu (formerly New Hebrides) indicated that it is a geminivirus. Preparations of virus particles contained one coat protein of tool. wt. about 27 500 and circular and linear single-stranded DNA about 2350 nucleotides in length.

Interference of large crabgrass (Digitaria sanguinalis) with snap beans

Weed Science, 2003
Abstract Field experiments were conducted to determine the effect of large crabgrass densities of 0.5 to 8 plants m−1 of row and emergence time on snap bean yield. Large crabgrass was planted either along with snap beans (early) or when the first trifoliate leaf of snap beans was opening (late).

Target-site mutation and enhanced metabolism endow resistance to nicosulfuron in a Digitaria sanguinalis population

Pesticide Biochemistry and Physiology, 2023
Digitaria sanguinalis is a competitive and annual grass weed that commonly infests crops across the world. In recent years, the control of D. sanguinalis by nicosulfuron has declined in Hebei Province, China. To determine the resistance mechanisms of D. sanguinalis to nicosulfuron, a population of D.

Crabgrass (Digitaria sanguinalis) Allelochemicals That Interfere with Crop Growth and the Soil Microbial Community

Journal of Agricultural and Food Chemistry, 2013
Three chemicals, veratric acid, maltol, and (−)-loliolide, were isolated from crabgrass and their structures were identified by spectroscopic analysis. The chemicals were detected in crabgrass root exudates and rhizosphere soils, and their concentrations ranged from 0.16 to 8.10 μg/g.

Importancia de la autopolinización en Digitaria sanguinalis

2017
Se realizaron dos experimentos para establecer el nivel de autopolinización de plantas de Digitaria sanguinalis. Para prevenir la polinización cruzada, las inflorescencias fueron tapadas. En la fase de senescencia se recolectaron las inflorescencias, se contaron los racimos espiciformes, se midió su longitud y se contaron y pesaron las espiguillas con ...

Demography of Digitaria sanguinalis: Effect of the emergence time on survival, reproduction, and biomass

Weed Biology and Management, 2010
Knowledge of weed population dynamics is crucial for designing effective weed management practises. A field experiment was carried out at Torre Marimon (near Barcelona, north‐eastern Spain) in 2006 and 2007 in order to study the effects of the seedling emergence time on Digitaria sanguinalis fitness.
