Human malignant melanoma and other solid cancers are largely driven by the inactivation of tumor suppressor genes and angiogenesis. Conventional treatments for cancer (surgery, radiation therapy, and chemotherapy) are ...
Weed management in maize farms is a time-specific activity and requires timely detection of weed infestations. The challenge to early detection of weeds is that many dicotyledonous crops and broad-leaved weeds often display ...
Tree-growing support programs are being implemented widely to enhance farmers’ involvement in land restoration schemes. However, the reasons why farmers will continue to engage in restoration activities when support programs ...
Biosolid applications based on crop nitrogen (N) demand have been widely adopted to attenuate nitrate leaching.
However, due to the dependence of N supply on the mineralization rate and the early release of the majority ...

The term ‘regenerative agriculture’ describes a rehabilitation and conservation approach to farming, which aims to enhance the sustainability of production. The approach consists of an array of practices that focus on the ...
Mercury (Hg) pollution remains an environmental global concern due to its non-degradable and toxic nature. Natural and anthropogenic sources of Hg adversely affect the functioning of aquatic ecosystems and biological ...
Outbreaks of potato blackleg and soft rot caused by Pectobacterium species and more recently Dickeya species across the U.S. mid-Atlantic region have caused yield loss due to poor emergence as well as losses from stem and ...
Pine plantations are the dominant species currently planted within the South African commercial forestry industry. Improvements in bio-economy markets for dissolving wood pulp products have seen an expansion in fast-growing ...
BACKGROUND : Riparian buffers are primarily implemented for their water quality functions
in agroecosystems. Their location in the agricultural landscape allows them to intercept
and process pollutants from immediately ...

Millions of people have been negatively affected by the Covid-19 (SARS-CoV-2) pandemic worldwide. Multiple stages characterize Covid-19 infection, initial stages include common symptoms that are milder in nature (fever, ...
Vegetatively propagated plants like yam are prone to yield losses by viruses as infection tends to build up in successive cycles of propagation. This study aimed to eliminate yam mosaic virus (YMV) from yam using an optimized ...
Badnaviruses infecting sugarcane, collectively called sugarcane bacilliform viruses (SCBVs), are reported worldwide and are responsible for causing leaf fleck disease in sugarcane. SCBVs are genetically heterogeneous members ...
Despite continued wild harvesting, there is limited data that provides estimates on the availability of African edible orchids as a resource, and that identifies the ecological drivers of their dynamics. This study was ...
