Copper ore mining and processing release hazardous post-flotation wastes that are difficult for remediation. The studied tailings were extremely rich in Cu (1800 mg kg-1) and contaminated with Co and Mn, and contained very little available forms of P, Fe, and Zn. The plants growing in tailings were distinctly enriched in Cu, Cd, Co, Ni, and Pb, and the concentration of copper achived the critic...

A 50-yr study at Fairbanks, AK, was started in 1984 to determine soil seed longevity of 17 weed species. Seeds were buried in mesh bags 2and 15-cm deep and were recovered 0.7, 1.7, 2.7, 3.7, 4.7, 6.7, 9.7, 19.7, and 24.7 yr later. Viability was determined using germination and tetrazolium tests. By 24.7 yr after burial (YAB), no viable seeds were found for common hempnettle, flixweed, foxtail b...

Bois noir (BN) grapevine disease is associated with ‘Candidatus Phytoplasma solani’ (CaPsol), a pathogen complex ecology including multiple insect vectors and plant hosts. A key point to improve the effectiveness of BN control strategies consists in determining epidemiological role ground-cover weeds. The present study employed multidisciplinary approach, based on application spatial (spatial a...

Field experiments were conducted to study weed population shifts in long-term conservation tillage systems. The objectives of this study were to determine weed community abundance, diversity and composition on conventional tillage (CT), minimum tillage (MT), no-tillage with paraplow (ZT) and no-tillage (NT) systems, and to identify species that are associated with specific tillage systems. The ...

Juglanin (Jug) is obtained from the crude extract of Polygonum aviculare, exerting suppressive activity against cancer cell progression in vitro and in vivo. Juglanin administration causes apoptosis and reactive oxygen species (ROS) in different types of cells through regulating various signaling pathways. In our study, the effects of juglanin on non-small cell lung cancer were investigated. A ...

Greenhouse and laboratory studies were conducted to determine the identity and pathogenicity of Diaporthe– Phomopsis species complex recovered from eight weed species. The identifications of the eight isolates representing four taxa, including two apparently undescribed species of Phomopsis, were based on colony features in pure culture, morphology of alpha or beta-conidia, and internal transcr...

Antimicrobial resistance (AMR) has now emerged as a global public health crisis, requiring the discovery of new and novel antimicrobial compounds, that may be precursors future therapeutic antibiotics. Chinese Herbal Medicine (CHM) comes with rich pedigree holistic empirical usage in Asia for last 5000 years. Extracts Anemarrhena asphodeloides Bunge, Angelica sinensis (Oliv.) Diels, Dianthus su...
