The interactions of crops with root-colonizing endophytic microorganisms are highly relevant to agriculture, because endophytes can modify plant resistance pests and increase crop yields. We investigated the between host Zea mays fungus Trichoderma virens at 5 days postinoculation grown in a hydroponic system. Wild-type T. two knockout mutants, deletion genes tv2og1 or vir4 involved specialized...

Abstract An interesting specimen of Ficus L. was collected from the Idukki district Kerala. Based on detailed examination with protologues, literatures and type specimens, plant identified as virens Aiton var. dispersa Chantaras. This is first report occurrence this taxon in India. A description, photographs, illustrations, comparison allied taxa identification key are provided.

samples were collected from soil and as well from phyllosphere of rice plant and subjected to dilution plate technique on rbsf trichoderma selective medium. a total of 202 trichoderma isolates were obtained from rice fields at different geographical locations distributed all over mazandaran province. single spore isolates were obtained and genomic dna extracted from all the isolates using dna e...

Fungi have a plethora of chitinases, which can be phylogenetically divided into three subgroups (A, B and C). Subgroup C (sgC) chitinases are especially interesting due to their multiple carbohydrate-binding modules, but they have not been investigated in detail yet. In this study, we analyzed sgC chitinases in the mycoparasites Trichoderma atroviride and Trichoderma virens. The expression of s...

Abstract Models of speciation in African rain forests have stressed either the role of isolation or ecological gradients. Here we contrast patterns of morphological and genetic divergence in parapatric and allopatric populations of the Little Greenbul, Andropadus virens, within different and similar habitats. We sampled 263 individuals from 18 sites and four different habitat types in Upper and...

Transitions from sexual to asexual reproduction are often coupled with elevations in ploidy. As a consequence, the importance of ploidy per se for the maintenance and spread of asexual populations is unclear. To examine the effects of ploidy and asexual reproduction as independent determinants of the success of asexual lineages, we sampled diploid sexual, diploid asexual, and triploid asexual E...
