Mesoderm represents the evolutionary youngest germ layer and forms numerous novel tissues in bilaterian animals. Despite the established conservation of the gene regulatory networks that drive mesoderm differentiation (e.g. myogenesis), mechanisms of mesoderm specification are highly variable in distant model species. Thus, broader phylogenetic sampling is required to reveal common features of ...
Transitions from sexual to asexual reproduction are often associated with polyploidy and increased chromosomal plasticity in asexuals. We investigated chromosomes in the freshwater ostracod species Eucypris virens (Jurine, 1820), where sexual, asexual and mixed populations can be found. Our initial karyotyping of multiple populations from Europe and North Africa, both sexual and asexual, reveal...
Accidental pollution incidents are common in the marine environment and are often caused by oil-related activities. Here the potential of such an incident to disrupt reproduction in two polychaete species is investigated, using an environmentally relevant preparation of weathered Forties crude oil, i.e. the water accommodated fraction (WAF). Oocytes were collected and exposed to three concentra...
The present study evaluated the removal efficiency of two dyes, Congo red (CR) and malachite green (MG), using either fresh or dry fungal biomass species Trichoderma (T. virens T. viride) activated carbon. After 24 h, CR obtained with was higher than that For MG dye, average carbon (99%) those viride virens. Experimental results for showed a good correlation Langmuir isotherms. adsorption rates...
Understanding metal toxicity to benthic systems is still an ecotoxicological priority and, although numerous biomarkers exist, a multi-biomarker and endpoint approach with sediment as the delivery matrix combined life-history relevant exposure timescales missing. Here we assess potential by measuring suite of endpoints after exposing ecologically important polychaete Alitta(Nereis)virens spiked...
The investigation was carried out at the laboratory of Plant Pathology Department, SASRD, Nagaland University (NU), Medziphema Campus, Nagaland, India during year kharif (August-October, 2020) to evaluate antagonistic potentiality Trichoderma spp. (T. harzianum, T. asperellum and virens) against three diseases pigeonpea viz. Alternaria leaf spot (Alternaria alternata), Collar rot (Sclerotium ro...
Dieback disease caused by L. theobromae has destroyed nutmeg plantations in Aceh Selatan. Until now, effective control not been found, while farmer continue to use pesticides that have a negative impact on the environment. Therefore, biological is an alternative environmentally friendly being promoted. The purpose of this researth was dieback inducing resistance using three spesies Trichoderma ...
Metal coordination chemistry is common in biology, with many proteins containing metal ion-based structural motifs or catalytic centers. An interesting example of nature’s use coordinate bonding to create a proteinaceous material found the Alitta virens marine worm jaw. Inspired by Zn+2 cross-linked polymers A. virens, we have extended cross-linking preceramic polymers. Commercially available S...
Sugar beet cyst forming nematode (Heterodera schachtii) is one of the most important pathogens of the sugar beet in Iran. For biological control of Heterodera schachtii, 10 isolates of Trichoderma related to two species T. harzianum and T. virens were examined in laboratory and green house on eggs and cysts for two years. Results obtained from the laboratory assay showed that isolates of Tricho...
