More than bindin divergence: reproductive isolation between sympatric subspecies of a sea urchin by asynchronous spawning
submitted by BraAdrie 1 hour ago
The evolution of reproductive barriers is crucial to the process of speciation. In the Echinoidea, studies have focused on divergence in the gamete recognition protein, bindin, as the primary isolating mechanism among species. As such, the capacity of alternate mechanisms to be effective reproduc...

Connecting the dots of nonlinear reaction norms unravels the threads of genotype-environment interaction in drosophila
submitted by jinnefir 1 hour ago
Two contrasting views can characterize the attitude of many studies towards reaction norms (RN). An “optimistic” view attempts to use a linear model to describe RN variation; and a “pessimistic” view emphasizes RNs complexity without using any model to describe them. Here, we have analyze...

Proteomic changes in response to potassium starvation in the extremophilic yeast Debaryomyces hansenii
submitted by rochilt4ak 1 hour ago
In this work we performed for the first time a proteomic approach to the processes induced by long-term potassium starvation in the halotolerant yeast Debaryomyces hansenii. The proteomic profile under this ionic stress conditions shows that important changes in gene expression take place as an a...

Effects of probiotics, probiotic DNA and the CpG oligodeoxynucleotides on ovalbumin-sensitized Brown-Norway rats via TLR9/NF-κB pathway
submitted by DustJunior 1 hour ago
The aim of the study was to investigate the effect of living probiotics, probiotic DNA and the synthetic oligodeoxynucleotides containing CpG motifs (CpG-ODN) on both immune response and intestinal barrier function in ovalbumin-sensitized rat and the underlying mechanisms. Brown-Norway rats were ...

A one dose experimental cholera vaccine
submitted by omoloa 1 hour ago
The number of cholera vaccine doses required for immunity is a constraint during epidemic cholera. Protective immunity following one dose of multiple Vibrio cholerae (Vc) colonization factors (Inaba LPS El Tor, TcpA, TcpF, and CBP-A) has not been directly tested in even though individual Vc colon...

Lipopolysaccharide O-antigen of Enterohemorrhagic Escherichia coli O157:H7 is required for killing both insects and mammals
submitted by xbb 1 hour ago
Studies of Enterohemorrhagic Escherichia coli (EHEC) infection mechanisms using mammals require large numbers of animals and are both costly and associated with ethical problems. Here we evaluated the pathogenic mechanisms of EHEC in the silkworm model. Injection of a clinically isolated EHEC O15...

Comparative analysis of P2-type remnant prophage loci in Xenorhabdus bovienii and Xenorhabdus nematophila required for xenorhabdicin production
submitted by leno6691 1 hour ago
The xnp1 remnant P2-type prophage of Xenorhabdus nematophila produces xenorhabdicin that is active against closely related species. Xenorhabdicin had not been characterized previously in other Xenorhabdus species. Here we show xenorhabdicin production in six different strains of X. bovienii. The ...
