Article Abstract
In this work, we report an analysis of the draft genome of the blueberry ( spp. var. Biloxi) growth-promoting endophyte , strain COPE52. The genome of COPE52 consists of a single 5,806,513 bp replicon, with a 35.1% G + C content. Strain COPE52 was strongly affiliated to species, based on species delimitation cut-off values established for average nucleotide identity (> 95-96%), genome-to genome distance calculator (> 70%) and phylogenomic analysis. The RAST genomic annotation of the COPE52 strain revealed a total of 5979 total genes, including 5631 protein-coding genes, 11 rRNA genes, 5 ncRNAs, 81 tRNA genes, and 251 pseudogenes. To further validate the in silico analysis results, experiments were carried out to detect the production of indoleacetic acid, protease activity, and the emission of volatiles like acetoin, 2,3-butanediol and dimethyl disulphide as potential plant growth-promoting mechanisms. COPE52 also showed antifungal action against the grey mould phytopathogen, , during in vitro bioassays. In addition, inoculation with strain COPE52 promoted growth biomass and chlorophyll content in blueberry plants ( spp. var. Biloxi) under greenhouse conditions. To our knowledge, this is the first study showing genomic and experimental evidence of as plant growth-promoting bacteria (PGPB).
var. Besser, a perennial herb of the Araceae family, was first reported in the Shen Nong's Herbal Classic and is widely distributed in southern China (Li 1979). It is important in traditional Chinese medicine for treating heart, stomach, and brain ailments (Lam et al.

Pseudo-nitzschia harmful algal blooms have recently caused elevated domoic acid in coastal environments of the Northeast United States. In 2017, the toxigenic species P. australis was observed in Narragansett Bay, Rhode Island, a temperate estuarine ecosystem, for the first time since 2009 when DNA monitoring for Pseudo-nitzschia species began.
Recently, species clustering within has been identified as complex, encompassing validly published names, including and , with some strains potentially delineating new species. In this study, genomes of strains isolated from a bacterial heart rot outbreak in pineapple ( var. ) on Oahu, Hawaii, along with two strains from pineapple in Malaysia, were sequenced.

Rice is an important agricultural crop that faces serious challenges from pathogens, pests, and weeds during growth stages. Meanwhile, these organisms would interact with each other to increase the level of destruction. The previous studies showed that barnyard grass (Echinochloa spp) could be used as a temporary host to increase infestation of small brown planthopper (SBPH, Laodelphax striatellus), which is one of the main polyphagous pests.
* A genome-wide study using RNA-seq methods identified 13,778 differentially expressed genes in the Mexican avocado variety over 21 days of infection, revealing six clusters linked to specific biological processes.
* The research also found that 8 out of 57 identified miRNAs respond to fungal infection, regulating 569 target genes, marking a pioneering exploration of miRNAs in avocado defense responses.
