In Vitro Evaluation of the Biosurfactant Produced by Serratia ureilytica UTS with Antifungal and Nematicidal Activity Against Nacobbus aberrans.

In the present study, the nematicidal and fungicidal activity of the biosurfactant (BS) produced by the strain Serratia ureilytica UTS was evaluated. The highest mortality of J2 juveniles of the nematode Nacobbus aberrans was 92.3% at a concentration of 30 mg/mL.

In Vivo Production, Development and Storage of (Nematoda: Rhabditida) in (Lepidoptera: Pyralidae).

Entomopathogenic nematodes have been used in biological control for some time and are an alternative for the control of insect pests, but during their implementation, situations have arisen that can be improved. These vary with each species and include their production and storage. , an entomopathogenic nematode (EPN), was monitored for its performance when produced in vivo, as well as its development using larvae, using the MC5-2014 strain isolated from soil samples in the municipality of Tepalcingo, Morelos, México.

Plasmids of the incompatibility group FIB occur in Klebsiella variicola from diverse ecological niches.

Plasmids play a fundamental role in the evolution of bacteria by allowing them to adapt to different environments and acquire, through horizontal transfer, genes that confer resistance to different classes of antibiotics. Using the available in vitro and in silico plasmid typing systems, we analyzed a set of isolates and public genomes of K. variicola to study its plasmid diversity.

A Versatile Peroxidase from the Fungus Confers Abiotic Stress Tolerance in Transgenic Tobacco Plants.

White-rot fungi are efficient lignin degraders due to the secretion of lignin peroxidase, manganese peroxidase, laccase, and versatile peroxidase (VP) on decayed wood. The VP is a high-redox-potential enzyme and could be used to detoxify reactive oxygen species (ROS), which accumulate in plants during biotic and abiotic stresses. We cloned the gene and expressed it via the transformation procedure in transgenic tobacco plants to assay their tolerance to different abiotic stress conditions.

(Nematoda: Rhabditida) isolated in sugar cane soils in Mexico with potential to be used as entomopathogenic nematode.

A survey of entomopathogenic nematodes was conducted in sugar cane crops in a total of 14 soils, and positive results were obtained for strain MC5-2014 in the municipality of Tepalcingo, Morelos, in soil with a sandy loam texture and a pH of 6.4. Species determination was performed via morphological and morphometric techniques by searching for a tubular stoma with a swollen cylindrical pharyngeal body and a metacorpus in the basal part.

Enhanced Tolerance against a Fungal Pathogen and Insect Resistance in Transgenic Tobacco Plants Overexpressing an Endochitinase Gene from .

In this study we cloned a chitinase gene (), from isolated from the corpse of a lepidopteran, which is an important sugarcane pest. The chitinase gene amplified from the genome was cloned into the transformation vector p2X35SChiC and used to transform tobacco ( L. cv Petit Havana SR1).

Draft Genome Sequences of Endophytic Isolates of Klebsiella variicola and Klebsiella pneumoniae Obtained from the Same Sugarcane Plant.

Endophytic KvMx2 and KpMx1 isolates obtained from the same sugarcane stem were used for whole-genome sequencing. The genomes revealed clear differences in essential genes for plant growth, development, and detoxification, as well as nitrogen fixation, catalases, cellulases, and shared virulence factors described in the pathogen.

Draft Genome Sequence of Arthrobacter chlorophenolicus Strain Mor30.16, Isolated from the Bean Rhizosphere.

Bacteria of the genus Arthrobacter are commonly found in the soil and plant rhizosphere. In this study we report the draft genome of Arthrobacter chlorophenolicus strain Mor30.16 that was isolated from rhizosphere of beans grown in Cuernavaca Morelos, Mexico.

Isolation and characterization of functional insertion sequences of rhizobia.

Rhizobia are a group of bacteria that form nodules on the roots of legume host plants. The sequenced genomes of the rhizobia are characterized by the presence of many putative insertion sequences (IS) elements. However, it is unknown whether these IS elements are functional and it is therefore relevant to assess their transposition activity.
