Evolutionary theory predicts that sexually antagonistic mutations accumulate differentially on the X chromosome and autosomes in species with an XY sex-determination system, with effects (masculinization or feminization of the X) depending on the dominance of mutations. Organisms with alternative modes of inheritance of sex chromosomes offer interesting opportunities for studying sexual conflic...
Effective translation of research findings from laboratory to agricultural fields is essential for the success of biocontrol or growth promotion trials employing beneficial microorganisms. The rhizosphere is to be viewed holistically as a dynamic ecological niche comprising of diverse microorganisms including competitors and noxious antagonists to the bio-inoculant. This study was undertaken to...
Antagonistic phenotypic plasticity may strongly influence trait evolution in tightly interacting predator-prey pairs as well as the role that trait plasticity plays in community dynamics. Most work on trait plasticity has focused on single predator-prey pairs, but prey must often contend with multiple predators in natural environments. Hence, a better understanding of the evolutionary and ecolo...
Sodium taurocholate is able to produce a decrease in permeability and to antagonize NaCl. This confirms the hypothesis that antagonistic relations can be predicted from studies on the permeability of pure substances.
We compared the ability of cellular and viral Jun (c-Jun and v-Jun) to transactivate target genes. c-Jun and v-Jun bind specifically to 12-O-tetradecanoylphorbol-13-acetate responsive elements [TREs, also called activator protein 1 (AP-1) motifs]. However, whereas c-Jun activates TRE-controlled promoters, v-Jun represses them. Cotransfection of the two Jun proteins reduces c-Jun-dependent trans...
Angiotensin II (Ang II) is a critical effector in the renin-angiotensin system (RAS), which modulates cardiovascular homeostasis, and the matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinases (TIMPs) related metabolism of extracellular matrix (ECM). Angiotensin(1-7) [Ang(1-7)] is another bioactive peptide in the RAS and is considered to have opposite effects to Ang...
the present investigation was carried out to isolate and characterize antagonistic bacteria against wilt causing fungal pathogen i.e. fusarium oxysporum, from the rhizosphere of tomato. fifty-six bacterial strains were isolated from the rhizosphere soil samples of healthy tomato fields, collected from different locations of faridabad district, haryana, india. out of these, ten isolates were fou...
The nuclear farnesoid X receptor (FXR) is a ligand activated transcription factor and acts as cellular sensor for bile acids. In this role, FXR is a highly important liver protector and FXR inhibition by antagonists or knockout has shown several deleterious effects. A recent report characterized non-steroidal anti-rheumatic drugs (NSAIDs) such as ibuprofen or diclofenac as FXR antagonists and l...
antibiotics are the best known products of actinomycete. over 5,000 antibiotics have been identified from the cultures of gram positive and gram-negative organisms, and filamentous fungi, but only about 100 antibiotics have commercially been used to treat human, animal and plant diseases. the genus, streptomycete, is responsible for the formation of more than 60% of known antibiotics. bacterial...
