Follicle-stimulating hormone receptor (FSHR), which mediates the functioning of FSH, plays a central role in reproduction. We investigated bovine FSHR gene polymorphisms and analyzed their relationships with pregnancy rates after embryo transfer and with hormone concentrations on the day of embryo transfer. One reported SNP of FSHR, G-278A, located in the 5'-upstream region, was analyzed and th...
Cell-to-cell communication, or quorum-sensing (QS), systems are employed by bacteria for promoting collective behaviour within a population. An analysis to detect QS signal molecules in 43 species of the Halomonadaceae family revealed that they produced N-acyl homoserine lactones (AHLs), which suggests that the QS system is widespread throughout this group of bacteria. Thin-layer chromatography...
background: luxi is a component of the quorum sensing signaling pathway in vibrio fischeri responsible for the inducer synthesis that is essential for bioluminescence. methods: homology modeling of luxi was carried out using phyre2 and refined with the galaxyweb server. five models were generated and evaluated by errat, anolea, qmean6, and procheck. results: five refined models were generated b...
Quorum sensing (QS) is the ability of microbes to sense and respond to their own population density, which typically results in cooperative activity (Fuqua et al., 1994). This form of microbial communication is important to agriculture and human health as they often participate in the regulation of genes important for host interactions. The classic example of QS in bacteria is performed by the ...

Rhodobacteraceae strain PD-2 was isolated from the marine microalga Prorocentrum donghaiense. It has algicidal activity toward its host and could produce N-acylhomoserine lactone signals. Here, we present the draft genome of strain PD-2, which contains 5,227,214 bp with an average GC content of 66.19%. There were 4,864 encoding gene sequences and two clusters of luxI and luxR homologues identif...
Here, we report the whole-genome sequences and annotation of five oligotrophic bacteria from two sites within the Lechuguilla Cave in the Carlsbad Caverns National Park, NM. Three of the five genomes contain an acyl-homoserine lactone signal synthase ortholog (luxI) that is involved in cell-to-cell communication via quorum sensing.
Agrobacterium tumefaciens P4 is a quorum-sensing-signal-producing bacterium that has been isolated from the tobacco rhizosphere. This strain belongs to genomospecies 1 of the A. tumefaciens complex; it is avirulent on various putative host plants, devoid of the Ti plasmid, and contains a luxI homolog on the At plasmid.
Here, we report a draft 5.25-Mb genome sequence of Pseudoalteromonas sp. 520P1, a marine violacein-producing bacterium isolated from the Pacific coast of Japan. Genome annotation by BLAST searches revealed the presence of one acylhomoserine lactone (AHL) synthase (luxI) and five AHL receptor protein (luxR) gene homologs.
