Abstract Plant growth promoting rhizobacteria (PGPRs) play significant roles in improving plant growth. Likewise, Mycorrhizal Helper Bacteria (MHB) enhance AM fungi fitness by promoting spore germination and providing protection against pathogens. This PGPR and MHB synergistic association can be exploited to introduce …

ABSTRACT Arbuscular mycorrhizal fungi are gaining prominence in agriculture because of their role in enhancing crop nutrient uptake and stress tolerance. Soil management practices, however, may pose a non‐optimal environment for arbuscular mycorrhizal (AM) fungal functioning. The impact of crop rotation and …

Taxonomic identification of arbuscular mycorrhizal (AM) fungal spores extracted directly from the field is sometimes difficult because spores are often degraded or parasitized by other organisms. Single-spore inoculation of a suitable host plant allows for establishing monosporic cultures of AM fungi. This …

The influence of fire regimes on soil microbial diversity in montane grasslands is a relatively unexplored area of interest. Understanding the belowground diversity is a crucial stepping-stone toward unravelling community dynamics, nutrient sequestration, and overall ecosystem stability. In this study, metabarcoding was …

Anthropogenic activities have contributed to the increased atmospheric concentration of greenhouse gases, which are an important contributor to climate change. From 1940 to 2004, global emissions increased by 70%, and projections suggest a continual increase by 2050 due to agriculture, forestry, and …

Xylanases are glycoside hydrolases (GH) that degrade β-1,4-xylan, a linear polysaccharide found as hemicellulose in cell wall of plants. Endoxylanase (Endo-1,4-β-xylanase, EC 3.2.1.8) randomly catalyses xylan to produce varying short xylooligosaccharides (XOS). This study aimed to determine the characteristics of a partially …

The South African forestry industry covers approximately 1.3 million hectares and is dependent on exotic pine and eucalypt species. Nursery seedlings are not inoculated with ectomycorrhizal (ECM) fungi. This investigation assessed levels of naturally occurring ECM colonisation of Pinus patula seedlings from …
