Apple leaf characteristics are the most important vegetative growth and development traits. The apple rhizosphere is also indirectly responsible for development. It provides roots with elements compounds that improve roots’ shoots’ application of exogenous plant regulators such as strigolactones (SLs) has become one main trends improving enhancing microbiome. This study aimed to investigate eff...

The understanding of the dynamic of soil-borne diseases is related to the microbial composition of the rhizosphere which is the key to progress in the field of biological control. Trichoderma spp. is commonly used as a biological control agent. The use of next generation sequencing approaches and quantitative PCR are two successful approaches to assess the effect of using compost as substrate f...

Hyperaccumulators are plants that can extract heavy metal ions from the soil and translocate those ions to the shoots, where they are sequestered and detoxified. Hyperaccumulation depends not only on the availability of mobilized metal ions in the soil, but also on the enhanced activity of metal transporters and metal chelators which may be provided by the plant or its associated microbes. The ...

Environmental concerns have led to the need of sustainable use of natural resources. The conventional agriculture caused considerable impacts on soils and waters. It is important to change certain agricultural managements to environmental cleaner techniques. The sustainable agriculture has pointed many approaches and techniques to reduce environmental impact. One of those strategies is the util...

atmospheric nitrogen fixation as an exclusive phenomenon is accomplished by nitrogenase enzyme of prokaryotic microorganisms namely diazotrophs including bacteria, actinomycets and cyanobacteria. nitrogen fixation is accomplished as form of symbiotic, associative and free-living systems. in free-living systems nitrogen is fixed without the help of plants. azotobacter, the first diazotroph was d...

Mimosa acutistipula var. ferrea (Fabaceae) is endemic to ferruginous tropical rocky outcrops in the eastern Amazon, also known as canga. Canga are often associated with mining activities and target of protection rehabilitation projects. M. stands out this biodiversity hotspot high growth rates, even rehabilitating minelands (RMs). However, little about diversity soil microorganisms interacting ...
