Endolysin LysEF-P10 shows potential as an alternative treatment strategy for multidrug-resistant Enterococcus faecalis infections.

Phage-derived lysins can hydrolyse bacterial cell walls and show great potential for combating Gram-positive pathogens. In this study, the potential of LysEF-P10, a new lysin derived from a isolated Enterococcus faecalis phage EF-P10, as an alternative treatment for multidrug-resistant E. faecalis infections, was studied.

The Bacteriophage EF-P29 Efficiently Protects against Lethal Vancomycin-Resistant and Alleviates Gut Microbiota Imbalance in a Murine Bacteremia Model.

is becoming an increasingly important opportunistic pathogen worldwide, especially because it can cause life-threatening nosocomial infections. Treating infections has become increasingly difficult because of the prevalence of multidrug-resistant strains. Because bacteriophages show specificity for their bacterial hosts, there has been a growth in interest in using phage therapies to combat the rising incidence of multidrug-resistant bacterial infections.

Therapeutic effect of Pseudomonas aeruginosa phage YH30 on mink hemorrhagic pneumonia.

Hemorrhagic pneumonia caused by Pseudomonas aeruginosa remains one of the most costly infectious diseases among farmed mink and commonly leads to large economic losses during mink production. The objective of this study was to investigate the potential of using phages as a therapy against hemorrhagic pneumonia in mink. A broad-host-range phage from the Podoviridae family, YH30, was isolated using the mink-originating P.

Characterization of Enterococcus faecium bacteriophage IME-EFm5 and its endolysin LysEFm5.

Due to the worldwide prevalence of antibiotic resistant strains, phages therapy has been revitalized recently. In this study, an Enterococcus faecium phage named IME-EFm5 was isolated from hospital sewage. Whole genomic sequence analysis demonstrated that IME-EFm5 belong to the Siphoviridae family, and has a double-stranded genome of 42,265bp (with a 35.

Identification and characterization of HolGH15: the holin of Staphylococcus aureus bacteriophage GH15.

Holins are phage-encoded hydrophobic membrane proteins that spontaneously and non-specifically accumulate and form lesions in the cytoplasmic membrane. The ORF72 gene (also designated HolGH15) derived from the genome of the Staphylococcus aureus phage GH15 was predicted to encode a membrane protein. An analysis indicated that the protein encoded by HolGH15 potentially consisted of two hydrophobic transmembrane helices.

Combination Therapy of LysGH15 and Apigenin as a New Strategy for Treating Pneumonia Caused by Staphylococcus aureus.

Pneumonia is one of the most prevalent Staphylococcus aureus-mediated diseases, and the treatment of this infection is becoming challenging due to the emergence of multidrug-resistant S. aureus, especially methicillin-resistant S. aureus (MRSA) strains.

Therapeutic effect of the YH6 phage in a murine hemorrhagic pneumonia model.

The treatment, in farmed mink, of hemorrhagic pneumonia caused by multidrug-resistant Pseudomonas aeruginosa strains has become increasingly difficult. This study investigated the potential use of phages as a therapy against hemorrhagic pneumonia caused by P. aeruginosa in a murine hemorrhagic pneumonia model.

A regulatory gene induces trichome formation and embryo lethality in tomato.

Trichomes are universal biological structures originating from the aerial epidermis, which serve as an excellent model to study plant differentiation at the cell level. Although the pathway regulating trichome formation in the Rosids has been well characterized, only very recently a few genes were identified for trichome initiation in the Asterids. In this study, we cloned Woolly (Wo), essential for trichome formation in tomato.

A multiple stress-responsive gene ERD15 from Solanum pennellii confers stress tolerance in tobacco.

Wild species often show more tolerance to environmental stress factors than their cultivated counterparts. An early responsive-to-dehydration gene was cloned from a drought- and salt-tolerant wild tomato Solanum pennellii (SpERD15). SpERD15 transcript accumulated differentially in different organs, and was remarkably induced by dehydration, salinity, cold and treatment with plant growth regulators.

Overexpression of SlGMEs leads to ascorbate accumulation with enhanced oxidative stress, cold, and salt tolerance in tomato.

GDP-Mannose 3',5'-epimerase (GME; EC 5.1.3.

Over-expression of microRNA169 confers enhanced drought tolerance to tomato.

Plant miRNA regulates multiple developmental and physiological processes, including drought responses. We found that the accumulation of Sly-miR169 in tomato (Solanum lycopersicum) was induced by drought stress. Consequently, Sly-miR169 targets, namely, three nuclear factor Y subunit genes (SlNF-YA1/2/3) and one multidrug resistance-associated protein gene (SlMRP1), were significantly down-regulated by drought stress.

Expression of artificial microRNAs in tomato confers efficient and stable virus resistance in a cell-autonomous manner.

Expression of artificial microRNAs (amiRNAs) in plants can target and degrade the invading viral RNA, consequently conferring virus resistance. Two amiRNAs, targeting the coding sequence shared by the 2a and 2b genes and the highly conserved 3' untranslated region (UTR) of Cucumber mosaic virus (CMV), respectively, were generated and introduced into the susceptible tomato. The transgenic tomato plants expressing amiRNAs displayed effective resistance to CMV infection and CMV mixed with non-targeted viruses, including tobacco mosaic virus and tomato yellow leaf curl virus.

Transcriptional profiles of drought-responsive genes in modulating transcription signal transduction, and biochemical pathways in tomato.

To unravel the molecular mechanisms of drought responses in tomato, gene expression profiles of two drought-tolerant lines identified from a population of Solanum pennellii introgression lines, and the recurrent parent S. lycopersicum cv. M82, a drought-sensitive cultivar, were investigated under drought stress using tomato microarrays.
