Functional plant strategies mediate post-fire ash–precipitation effects on soil–vegetation feedbacks in a dry-valley forest ecosystem: implications for restoration

Trees, Forests and People
Wildfire fundamentally alters forest soil properties and vegetation dynamics through changes in ash deposition and post-fire precipitation, yet the coupled mechanisms governing soil–plant feedbacks remain unclear.

AN ECOLOGICAL SURVEY OF THE WEED FLORA IN THE MAJOR ROOT CROP AREAS IN THE PHILIPPINES

Annals of Tropical Research, 1981
Different root crop-growing areas in the Philippines were surveyed during the wet season to determine the weed species associated with different root and tuber crops, namely, sweet potato, cassava, yam and white potato.

Transformation of Digitaria sanguinalis with XvPer1, a novel antioxidant

, 2002
Digitaria 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.

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).

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.

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.
