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...

In grasslands, saprotrophic fungi, including basidiomycetes, are major decomposers of dead organic matter, although spatial distributions of their mycelial assemblages are little described. The aim of this study was to characterise the scale and distribution of saprotrophic fungal communities in a coastal grassland soil using terminal restriction fragment length polymorphism (T-RFLP). Soil fung...

Root rot disease is one of the most serious diseases that significantly reduces plant's productivity, commonly known as collar rot, foot or damping off. The main symptom this condition newly emerging seedlings collapse and die in areas with severe infection, majority may before after emergence. Due to C. Deodara which our state tree, damage caused by it there was urgent need identify study so d...

Internally transcribed spacer (ITS) regions of ribosomal DNA are widely used in reconstructing phylogenies at lower taxonomic levels (see, e.g., Vilgalys and Sun 1994; Baldwin et al. 1995). Ribosomal genes are tandemly repeated, and the paralogs are usually identical due to a poorly understood process of concerted evolution. Proposed mechanisms of concerted evolution include unequal crossing ov...

A total of 198 cereal samples (53 maize, 54 sorghum, 37 paddy and 54 wheat) were collected from 11 districts of Karnataka to understand the percent infection (PI), relative density (RD) and their frequency (Fr) caused by Fusarium spp. All samples were screened by agar plating method using MGA 2.5 agar media and incubated at 25 ± 2 °C for 3-5 days. The study revealed the association of 10 differ...
