Effect of NaCl stress on exoproteome profiles of EB2003A and EL2006H.

Salt stress can affect survival, multiplication and ability of plant growth promoting microorganisms to enhance plant growth. Changes in a microbe's proteome profile is one of the mechanisms employed by PGPM to enhance tolerance of salt stress. This study was focused on understanding changes in the exoproteome profile of EB2003A and EL2006H when exposed to salt stress.

Cell-Free Supernatant (CFS) from EB2004S and EL2006H Cultured at a Range of pH Levels Modulates Potato Plant Growth under Greenhouse Conditions.

Agriculture involving industrial fertilizers is another major human made contributing factor to soil pH variation after natural factors such as soil parent rock, weathering time span, climate, and vegetation. The current study assessed the potential effect of cell-free supernatant (CFS) obtained from EB2004S and EL2006H cultured at three pH levels (5, 7, and 8) on potato (var Goldrush) growth enhancement in a greenhouse pot experiment. The results showed that CFSs obtained from EB2004S and EL2006H cultured at pH 5 significantly improved photosynthetic rates, stomatal conductance, root fresh weight, and whole plant fresh weight.

EL2006H cell-free supernatant enhances growth variables in (maize), L. Merill (soybean) and (potato) exposed to NaCl stress.

Plant growth promoting microorganisms and their derived compounds, such as cell-free supernatant (CFS), enhance plant growth under stressed and non stressed conditions. Such technology is sustainable and environmentally friendly, which is desirable amidst the climate change threat. The current study evaluated the effect of CFS obtained from EL2006H on its ability to enhance mean percentage germination and mean radicle length of corn and soybean, as well as growth parameters of potato, using treatment formulations that consisted of 0.

Secretome Analysis of the Plant Biostimulant Bacteria Strains (EB2004S) and (EL2006H) in Response to pH Changes.

It is well-known that there is a high frequency of plant-growth-promoting strains in and that these can be effective under both stressful and stress-free conditions. There are very few studies of this activity in the case of . In this study, the effects of pH on the secretome (proteins) in the cell-free supernatants of two bacterial strains were evaluated.

, a stem rot disease in potato: Characterization, distribution and management.

Potato ( L.) is one of the most important crops in maintaining global food security. Plant stand and yield are affected by production technology, climate, soil type, and biotic factors such as insects and diseases.

The Coevolution of Plants and Microbes Underpins Sustainable Agriculture.

Terrestrial plants evolution occurred in the presence of microbes, the phytomicrobiome. The rhizosphere microbial community is the most abundant and diverse subset of the phytomicrobiome and can include both beneficial and parasitic/pathogenic microbes. Prokaryotes of the phytomicrobiome have evolved relationships with plants that range from non-dependent interactions to dependent endosymbionts.

Plant Holobiont Theory: The Phytomicrobiome Plays a Central Role in Evolution and Success.

Under natural conditions, plants are always associated with a well-orchestrated community of microbes-the phytomicrobiome. The nature and degree of microbial effect on the plant host can be positive, neutral, or negative, and depends largely on the environment. The phytomicrobiome is integral for plant growth and function; microbes play a key role in plant nutrient acquisition, biotic and abiotic stress management, physiology regulation through microbe-to-plant signals, and growth regulation via the production of phytohormones.

Phylogenetically diverse group of native bacterial symbionts isolated from root nodules of groundnut (Arachis hypogaea L.) in South Africa.

Groundnut is an economically important N-fixing legume that can contribute about 100-190kgNha to cropping systems. In this study, groundnut-nodulating native rhizobia in South African soils were isolated from root nodules. Genetic analysis of isolates was done using restriction fragment length polymorphism (RFLP)-PCR of the intergenic spacer (IGS) region of 16S-23S rDNA.

Identification and characterization of phages parasitic on bradyrhizobia nodulating groundnut ( L.) in South Africa.

In this study, three lytic phages (namely, PRSA-1, PRSA-2 and PRSA-26) were isolated and characterized for their morphology, host range, profile and restriction endonuclease banding pattern of genome size. The susceptible rhizobial isolates were identified by H and II sequence analysis. The results showed that all phages had polyhedral head with non-contractile tail which confirmed their relationship with the family.
