Antifungal Activity of Phyllospheric Bacteria Isolated from against .

Peru is one of the leading countries that produce and export specialty coffees, favorably positioned in the international markets for its physical and organoleptic cup qualities. In recent years, yellow coffee rust caused by the phytopathogenic fungus stands out as one of the main phytosanitary diseases that affect coffee culture yields. Many studies have demonstrated bacteria antagonistic activity against a number of phytopathogen fungi.

Role of AZO16M2 in Phosphate Solubilization and Ex Vitro Acclimatization of var. Valery.

AZO16M2, was characterized for its phosphate solubilization capacity to improve the establishment and survival of var. Valery seedlings under ex-acclimation. Three phosphorus sources (Rock Phosphate (RF), Ca(PO) and KHPO) and two types of substrate (sand:vermiculite (1:1) and Premix N°8) were selected.

Plant Growth Promoting Bacteria and Arbuscular Mycorrhizae Improve the Growth of var. Zutano under Salt Stress Conditions.

In Peru, almost 50% of the national agricultural products come from the coast, highlighting the production of avocado. Much of this area has saline soils. Beneficial microorganisms can favorably contribute to mitigating the effect of salinity on crops.

Draft Genome Sequence of Bacillus halotolerans IcBac2.1, a Strain with Potential as a Phytopathogen Control Agent.

Several species of the genus are used as plant growth-promoting bacteria. In particular, species of the subtilis group are known as good antagonists of phytopathogenic fungi. Here, we report the draft genome sequence of a rhizospheric strain with promising abilities as a biocontrol agent.

Effects of Rhizobia Isolated from Coffee Fields in the High Jungle Peruvian Region, Tested on L. var. Red Kidney.

Soils in the high jungle region of Peru continuously face erosion due to heavy rain, which leads to significant nutrient losses. Leguminous plants may provide a sustainable solution to this problem due to their ability to fix atmospheric nitrogen with the help of symbiotic rhizospheric microbes that reside in their root nodules and help restore soil fertility. The aim of this study was to isolate native rhizobial strains that can form functional nodules in red kidney beans to help improve their growth, development, and yield in field conditions.

Plant microbiota modified by plant domestication.

Human life became largely dependent on agricultural products after distinct crop-domestication events occurred around 10,000 years ago in different geographical sites. Domestication selected suitable plants for human agricultural practices with unexpected consequences on plant microbiota, which has notable effects on plant growth and health. Among other traits, domestication has changed root architecture, exudation, or defense responses that could have modified plant microbiota.

Bioprospection of native psychrotolerant plant-growth-promoting rhizobacteria from Peruvian Andean Plateau soils associated with .

The Peruvian Andean Plateau, one of the main production areas of native varieties of , is exposed to abrupt decreases in environmental temperature, affecting crop production. Plant-growth-promoting rhizobacteria that tolerate low temperatures could be used as organic biofertilizers in this region. We aimed to bioprospect the native psychrotolerant bacteria of the quinoa rhizosphere in this region that show plant-growth-promoting traits.

Identification of the symbiosis island of Bradyrhizobium paxllaeri LMTR 21.

The complete symbiosis island (SI) of Bradyrhizobium paxllaeri LMTR 21, a mutualistic symbiont of the legume Phaseolus lunatus, was identified and analyzed. The SI was 646 kb in size, had lower G+C content than the genome average, and encoded not only nodulation and nitrogen fixation functions but also those for hydrogen uptake, vitamin and phytohormone biosynthesis, molybdenum transport, nonribosomal peptide synthesis, and type III secretion. Additionally, two divergent nodA genes were encoded in the SI.

Draft Genome Sequence of Rhizobium sophoriradicis H4, a Nitrogen-Fixing Bacterium Associated with the Leguminous Plant Phaseolus vulgaris on the Coast of Peru.

The genome sequence of H4, a nitrogen-fixing bacterium isolated from the common bean () in Peru, is reported here. The genome assembly revealed a 6.44-Mbp genome which was distributed into 95 contigs, with and values of 293 kbp and 9, respectively.

Complete Genome Sequence of the Symbiotic Strain Bradyrhizobium icense LMTR 13, Isolated from Lima Bean (Phaseolus lunatus) in Peru.

The complete genome sequence of LMTR 13, a root nodule bacterium isolated from the legume , is reported here. The genome consists of a circular 8,322,773-bp chromosome which codes for a large and novel symbiotic island as well as genes putatively involved in soil and root colonization.

Characterization and potential of plant growth promoting rhizobacteria isolated from native Andean crops.

Bacteria isolated from soil and rhizosphere samples collected in Peru from Andean crops were tested in vitro and in vivo to determine their potential as plant growth promoters and their ability to induce systemic resistance to Alternaria alternata in tomato plants. The isolates were identified by sequencing their 16S ribosomal RNA gene. Test for phosphate solubilization, and indolacetic acid were also carried out, together with in vitro antagonism assays in dual cultures towards the plant pathogens Fusarium solani, A.

Evaluation of plant growth promoting activity and heavy metal tolerance of psychrotrophic bacteria associated with maca ( Walp.) rhizosphere.

The high Andean plateau of Peru is known to suffer harsh environmental conditions. Acidic soils containing high amount of heavy metals due to mining activities and withstanding very low temperatures affect agricultural activities by diminishing crop quality and yield. In this context, plant growth promoting rhizobacteria (PGPR) adapted to low temperatures and tolerant to heavy metals can be considered as an environment-friendly biological alternative for andean crop management.
