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 ...
Irrigators are increasingly challenged to maintain or even increase production using less
water, sometimes of poorer quality, and often from unconventional sources. This paper describes
the main features of a newly ...
BACKGROUND : Phytochemicals and their derivatives/analogues represent over 50% of the current medicines worldwide in clinical use. Despite a significant contribution to the total bioactive natural plant products, aquatic ...
Accurate maps of tree species distributions are necessary for the sustainable management of
forests with desired ecological functions. However, image classification methods to produce species
distribution maps for ...
The marine sponge Neopetrosia exigua is known as a goldmine of novel compounds, yet its
pharmacological activities remain poorly characterised. Herein, this study investigates the bioactivities
of N. exigua collected ...

Facilitation is an interaction where one species (the benefactor) positively impacts another (the beneficiary). However, the reciprocal effects of beneficiaries on their benefactors are typically only documented using ...
A multi-tiered transcriptional network regulates xylem differentiation and secondary cell wall (SCW) formation in plants, with evidence of both conserved and lineage-specific SCW network architecture. We aimed to elucidate ...
Lucerne is regarded as the best legume crop for forage to be cultivated in South Africa. It is commonly used to produce good quality hay. It also plays an important role in soil conservation, regeneration, and crop rotation ...
