Abstract
Plants and their microbiomes, including plant growth-promoting bacteria (PGPB), can work as a team to reduce the adverse effects of different types of stress, including drought, heat, cold, and heavy metals stresses, as well as salinity in soils. These abiotic stresses are reviewed here, with an emphasis on salinity and its negative consequences on crops, due to their wide presence in cultivable soils around the world. Likewise, the factors that stimulate the salinity of soils and their impact on microbial diversity and plant physiology were also analyzed. In addition, the saline soils that exist in Mexico were analyzed as a case study. We also made some proposals for a more extensive use of bacterial bioinoculants in agriculture, particularly in developing countries. Finally, PGPB are highly relevant and extremely helpful in counteracting the toxic effects of soil salinity and improving crop growth and production; therefore, their use should be intensively promoted.

Abstract
Sustainable agriculture requires the recruitment of bacterial agents to control diverse plant diseases such as bacterial endophytes. Bacterial endophytes colonize and inhabit internal plant tissues without causing any apparent damage. Within the plant, these bacteria exert multiple beneficiary effects, including direct stimulation of plant growth by the action of phytohormones or the production of metabolites. However, bacterial endophytes also protect their plant host through biocontrol pathogens or by inducing plant innate immune system. The present work makes a systematic and in-depth review on the current state of endophytic bacterial diversity, their plant colonization strategies, and their potential roles as protective agents against plant diseases during pre- and post-harvest stages of crop productivity. In addition, an exploration of their beneficial effects on sustainable agriculture by reducing/eliminating the use of toxic agrochemicals was conducted. Finally, we propose diverse effective strategies for the application of endophytic bacteria as biological agents during both pre- and post-harvest stages, with the aim of protecting crop plants and their agricultural products.

Abstract
BACKGROUND Staphylococcus aureus is one of the main microorganisms that causes bovine mastitis, and its well-known virulence characteristics and interactions with the environment are used to aid the design of more efficient therapies. OBJECTIVES To determine whether the virulence traits, such as antibiotic resistance and biofilm-forming and internalization abilities, of S. aureus isolated from bovine mastitis are related to dairy production system types. METHODS The study was performed in the Mexican states of Guanajuato and Michoacan. Semi-intensive dairy farms (SIDFs) and family dairy farms (FDFs) (454 and 363 cows, respectively) were included. The 194 milk samples from mastitis affected quarters were collected and 92 strains of S. aureus were isolated and identified by biochemical and molecular tests. Antibiotic resistance, biofilm and internalization assays were performed on 30 randomly selected isolated strains to determine virulence traits, and these strains were equally allocated to the 2 dairy production systems. RESULTS All 30 selected strains displayed a high degree of resistance (50%-91.7%) to the antibiotics tested, but no significant difference was found between SIDF and FDF isolates. S. aureus strains from SIDFs had an average biofilm forming capacity of up to 36% (18.9%-53.1%), while S. aureus strains from FDFs registered an average of up to 53% (31.5%-77.8%) (p > 0.05). Internalization assays revealed a higher frequency of internalization capacity for strains isolated from FDFs (33.3%) than for those isolated from SIDFs (6.7%) (p > 0.05). fnbpA gen was detected in 46.6% of FDF strains and 33.3% of SIDF strains, and this difference was significant (p < 0.05). CONCLUSIONS Our findings show that the virulence traits of S. aureus isolates analyzed in this study, depend significantly on several factors, such as phenotype, genotype, and environmental conditions, which are significantly related to dairy production system type and daily management practices.

Abstract
En este trabajo investigamos la presencia, diversidad y relaciones filogenéticas de genes asociados a la tolerancia al arsénico (As) en 37 cepas del género Bacillus, aisladas de tapetes microbianos localizados en pozas termales en Araró, Michoacán, México. Se diseñaron oligonucleótidos específicos para la amplificación por PCR de los genes arsB (bomba de expulsión de arsenito) y arsC (arsenato reductasa), ACR3 (transportador de arsenito) y aoxB (arsenito oxidasa) del género Bacillus, detectando únicamente los genes arsB y arsC en 21 de las 37 cepas analizadas (56.7% del total). Los análisis tipo Blastx demuestran una alta identidad (84-100%) con bombas de expulsión de arsenito (ArsB) y proteínas arsenato reductasas (ArsC) de diversas cepas de los géneros Bacillus, Paenibacillus, Psychrobacter y Planococcus. Dichos análisis se confirmaron a través de la construcción de filogenias de los genes arsB y arsC. La detección de los genes arsB y arsC en cepas de Bacillus se correlacionó con valores de hipertolerancia al As, los cuales correspondieron a 32 y 128 mM de arsenito (III) y arsenato (V), respectivamente. Finalmente, los genes arsB y arsC identificados en cepas de Bacillus podrían ser un mecanismo de resistencia al arsénico en un ambiente acuático extremo, como las pozas termales de Araró.

Abstract
This work describes a novel rolling-circle replicating (RCR) plasmid pBMBt1 from Bacillus thuringiensis subsp. darmstadiensis (INTA Mo14-4) encoding an insecticidal crystal protein-like gene. pBMBt1 (6700 bp) contains three ORFs and their putative transcription initiation sites and Shine-Dalgarno sequences were localized. ORF1 encodes a 34.6 kDa protein which showed identity with the protein CryC53 from B. thuringiensis subsp. cameroun (24.6%), the Cry15Aa insecticidal crystal protein from B. thuringiensis subsp. thompsoni (21.9%) and the Mtx3 protein from Bacillus sphaericus (27.8%). The ORF2 (52.3 kDa) showed a 74% identity with the Mob protein coded by pUIBI-1 from B. thuringiensis subsp. entomocidus and 64% identity with the Mob protein of pBMY1 from Bacillus mycoides; both Mob proteins belong to the pMV158 superfamily. To evaluate the Mob protein, the plasmid pHTMob14-4 was constructed. This plasmid shows transfer frequencies of 9.1x10(-6) in B. thuringiensis subsp. israelensis (4Q7Gm(R)). The ORF3 (23.6 kDa) gene product is homologous to the Rep protein from the plasmid pBMYdx of B. mycoides (37.6%). A putative double-strand origin with significant homology to that of B. thuringiensis plasmids, and an ssoA-type single-strand origin were also identified. Detection of single-stranded pBMBt1 DNA replicating intermediaries suggests that replication occurs via the rolling-circle mechanism.

Abstract
This work describes a novel plasmid encoding resistance to lincomycin in a staphylococcal isolate associated with mastitis infection from dairy cows. The cryptic plasmid pBMSa1 (2750 bp) of Staphylococcus aureus SA35 was subcloned and sequenced. Two ORFs (ORF1 and ORF2) were identified, and their putative transcription initiation and Shine-Dalgarno sequence were localized. ORF1 encodes a 334-residue protein almost identical to the putative Rep proteins of previously sequenced S. aureus rolling-circle-replicating plasmids. ORF2 encodes a 162-amino acid protein sharing a high degree of homology with LinA proteins (lincosamide O-nucleotidyltransferases) described in a variety of S. aureus strains. Intracellular single-stranded pBMSa1 DNA replicating intermediaries were detected, suggesting replication via the rolling-circle mechanism. A putative double-strand origin with significant homology to that of pC194 and a ssoA-type single-strand origin homologous sequence were also identified.
