Tropicibacter oceani sp. nov., a novel sulfur-metabolizing bacteria isolated from the intertidal zone sediment of Chinese Yellow Sea.

In this study, we reported a Gram-stain-negative, rod-shaped, atrichous, and aerobic bacterial strain named YMD87, which was isolated from the intertidal zone sediment of Chinese Yellow Sea. Growth of strain YMD87 occurred at 10.0-40.

A soluble TLR5 is involved in PBLs activation and antibacterial immunity via TLR5M-MyD88-signaling pathway in tongue sole Cynoglossus semilaevis.

In higher vertebrates, there is only a membranal TLR5 (TLR5M), which is crucial for host defense against microbes via MyD88 signaling pathway. In teleost, both TLR5M and soluble TLR5 (TLR5S) are identified, whereas the antibacterial mechanism of TLR5S is largely unknown. In this study, we studied the immune antibacterial mechanism of Cynoglossus semilaevis TLR5S homologue (named CsTLR5S).

Membrane orthologs of TLR5 of tongue sole Cynoglossus semilaevis: Expression patterns, signaling pathway and antibacterial property.

Mammalian toll-like receptor 5 (TLR5) is crucial for recognizing bacterial flagellin and initiating the inflammatory signaling cascades via myeloid differentiation factor 88 (MyD88) signaling pathway, which plays vital roles in innate immune against pathogenic bacteria. Herein, we reported the signaling pathway and antibacterial property of tongue sole (Cynoglossus semilaevis) membrane forms of TLR5 (i.e.

CsIL-11, a teleost interleukin-11, is involved in promoting phagocytosis and antibacterial immune defense.

Interleukin (IL)-11 is a multifunctional cytokine belonging to the IL-6 family, which plays essential roles in immune response. However, much less is known about the immunological functions of IL-11 in teleost. In this study, we investigated the immune properties of a teleost IL-11 homologue (CsIL-11) from tongue sole Cynoglossus semilaevis.

A teleost interleukin-16 is implicated in peripheral blood leukocytes recruitment and anti-bacterial immunity.

Interleukin-16 (IL-16), as a lymphocyte chemoattractant cytokine, plays a crucial role in regulating cellular activities and anti-pathogen immunity. In teleost, the information about the antibacterial effect of IL-16 is scarce. In our study, we examined the immune functions of an IL-16 homologue (CsIL-16) from tongue sole Cynoglossus semilaevis.

Whole-Genome Sequencing of Micrococcus luteus MT1691313, Isolated from the Mariana Trench.

Micrococcus luteus MT1691313 is a Gram-positive bacterium isolated from the deep-sea sediment located at a 4,448-m depth in the Mariana Trench. Here, we report the complete genome sequence of this strain, which has a genome size of 2.32 Mb with a GC content of 72.

Interaction of high seawater temperature and light intensity on photosynthetic electron transport of eelgrass (Zostera marina L.).

The interaction of widely recognized causes of eelgrass decline (high seawater temperature and limited light intensity) on photosynthetic electron transport was investigated via chlorophyll fluorescence technique. High seawater temperature combined light intensity significantly increasing the relative maximum electron transport rate (rETR); at critical temperature of 30 °C, the rETR increased with the enhancement of light intensity, indicating the elevation of overall photosynthetic performance. Based on the magnitude of effect size (η), light intensity was the predominant factor affecting the performance index (PI), indicating that photosystem II (PSII) was sensitive to light intensity.
