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...

Bu çalışmada, Verticillium dahliae’nın gelişimi üzerine bazı fungal (Trichoderma harzianum, Trichoderma virens, asperellum, viride) ve maya (Saccharomyces cerevisiae) biyolojik kontrol etmenleri ile vermikompost salisilik asit organik maddelerin etkisi araştırılmıştır. Çalışma in vitro vivo koşullarda yürüyülmüş vitro’da antagonizmin derecesi yüzde olarak engelleme oranı belirlenmiştir. In inhi...

Members of genus Trichoderma are known worldwide for mycoparasitism. To gain a better insight into the organization and evolution of their genomes, we used an in silico approach to compare the occurrence, relative abundance and density of SSRs in Trichoderma atroviride, T. harzianum, T. reesei, and T. virens. Our analysis revealed that in all the four genome sequences studied, the occurrence, r...

In this study, effects of single and combined applications biocontrol agents; Trichoderma spp. (T. atroviride, T. virens) plant growth promoting rhizobacteria (Pseudomonas koreensis, Bacillus subtilis) on growth, wilt disease severity caused by Verticillium dahliae defence-related enzymes (peroxidase, polyphenol oxidase, phenylalanine ammonium lyase β-1,3 glucanase) eggplant, were investigated....

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...

Pigeonpea is one of the important pulse crop Madhya Pradesh, a State India. The plant gets infected by pathogen Fusarium udum causing wilt disease, which major constraints in production and productivity pigeonpea. present study aimed to carry out vitro condition assess possible use biocontrol consortia field conditions. Six Trichoderma viz., T1- T. viride + harzianum (JC-I), T2- virens (JC-2), ...

application of antagonistic agents in the rhizosphere of plants is an important approach in control of soil-borne pathogens. establishment and persistence of biocontrol agents in the soil is a major concern in biological control. this study aimed to determine the effect of plant debris of oak forests on activity of pseudomonas fluorescens and trichoderma vierns against meloidogyne javanica in t...
