background: although aberrant protamine (prm) ratios have been observed in infertile men, the mechanisms that implicit the uncoupling of prm1 and prm2 expression remain unclear. to uncover these mechanisms, in this observational study we have compared the prm1/prm2 mrna ratio and mrna contents of two regulatory factors of these genes. materials and methods: in this experimental study, sampling ...
Barley powdery mildew resistance (PM-R) genes control different infection phenotypes against avirulent strains of Blumeria graminis f. sp. hordei (Bgh). A subset of seven Pallas isolines, containing the PM-R genes Mla1, Mla12, Mlg, Mlk, Mlp and mlo5, revealed fast-, intermediateand slow-acting infection phenotypes. Scanning electron microscopy revealed the extent of Bgh development on each geno...
Eukaryotic ribosomes are made of two components, four ribosomal RNAs, and approximately 80 ribosomal proteins (r-proteins). The exact number of r-proteins and r-protein genes in higher plants is not known. The strong conservation in eukaryotic r-protein primary sequence allowed us to use the well-characterized rat (Rattus norvegicus) r-protein set to identify orthologues on the five haploid chr...
During infection, pathogens secrete an arsenal of molecules, collectively called effectors, key elements of pathogenesis which modulate innate immunity of the plant and facilitate infection. Some of these effectors can be recognized directly or indirectly by resistance (R) proteins from the plant and are then called avirulence (AVR) proteins. This recognition usually triggers defense responses ...
Background and Objective: Pseudomonas aeruginosa is an opportunistic pathogen causing nosocomial burn infections. Disease results from the production of numerous virulence factors, some of which are injected directly into the eukaryotic host cells via the type III secretion system (T3SS).The aim of this study was to determine the prevalence of cytotoxins encoding exoT, exoY, exoS and exoU genes...
