Mushroom associated microbes could be utilized to improve crop productivity providing nutrients, plant growth promoting substances, production of hydrolytic enzymes and protecting plant from biotic and abiotic stress. An endophyte designated as KUFC101 was isolated from fruit body of Pleurotus ostreatus and identified as Porostereum umbrinoalutaceu...

Fusarium incarnatum‐equiseti species complex infects a wide variety of food crops. Six fungal isolates were isolated from rotted roots of Dolichos lablab (hyacinth bean), Trichosanthes dioica (pointed gourd), Momordica dioica (spiny gourd), Capsicum frutescens (chilli) and Pisum sativum (garden pea), and identified as Fusarium spp., belonging to Fu...

Deciphering effector genes of plant‐pathogenic fungi is key to understanding their role in pathogenicity because acquisition of such genes through horizontal transfer may result in emergence of new pathogenic races. A full‐length (837 bp) Six1 gene has been cloned and sequenced from the genome of Fusarium oxysporum FPo isolated from roots of wilted...

The present study explores phytohormones production of Fusarium soil isolate and also their production under the condition of heavy metal stress. Fusarium sp. was recovered from an agricultural field of Murshidabad district in West Bengal, India. by soil dilution plate technique on selective pentachloronitrobenzene (PCNB) medium and was later ident...

The current study reports the effect of various cultural parameters on the gibberellic acid (GA) by Fusarium sp. isolated from an agricultural field of Murshidabad district in West Bengal, India. Gibberellin is one of the principal plant growth regulators that influence the overall developmental processes in angiosperms. The Fusarium sp. was isolat...

Macrofungal explorations of different temperate forests in the West Kameng district of Arunachal Pradesh, India, were undertaken. Thorough examination of these collections revealed a new member of Lactarius sect. Uvidi. We present Lactarius indoviolaceus sp. nov. with illustrated macro-and micro-description, phylogenetic analysis, and comparison wi...

Exploration of molecular structure of β-tubulin is key to understand mechanism of action of carbendazim since its activity depends on strong binding to β-tubulin. Resistance against the fungicide is often associated with mutation in β-tubulin gene. A full-length (1619 bp) β-tubulin gene has been cloned and sequenced from a carbendazim resistant and...

Carbendazim resistance in phytopathogenic Fusarium species is being an immense problem in agricultural practices. Carbendazim exerts fungicidal activity through preventing cell division of target fungi and by binding to β-tubulin, a major component of microtubule. Several point mutations in the β-tubulin gene contribute to carbendazim resistance. A...

Emergence of fungicide resistant phytopathogens under changing environmental condition is a serious problem in agriculture. Four Fusarium oxysporum isolates were isolated from four wilted crop plants (tomato, potato, pea and grass pea) and identified through conidial morphology and rDNA sequence analysis. Sensitivity of carbendazim and thiophanate...

The synthesis, structural investigation, spectral properties and DNA binding aspects of three dimetallic complexes, [Cu2(L²)2(H2O)2]∙H2O (1), [Ni2(L²)2(H2O)2] (2) and [Zn2(L²)2(H2O)2] (3), based on carboxylate containing new asymmetric tripodal ligand, 3-(carboxymethyl-pyridin-2-ylmethyl-amino)-propionic acid (H2L²) are reported. All the complexes...

Four Fusarium solani isolates were isolated from four agricultural soil samples of Murshidabad district, West Bengal, India and identified through morphological characterization and rDNA sequence analysis. Their carbendazim sensitivity were tested through radial growth assay and conidia germination assay. ED50 value calculated by regressing the mea...

Cellulase has tremendous industrial application. Fusarium spp. should be exploited as commercial source of cellulase. Three F. solani, three F. oxysporum and one F. chlamydosporum isolates have been recovered from soil, identified through rDNA sequence analysis and their cellulolytic activities have been characterized based on carboxymethylcellulos...

Background: Increasing concentration of toxic metals like cadmium (Cd) in the environment due to anthropogenic activities is one the serious global concern since these metals accumulate in soil and are often ʻbiologically magnifiedʼ and enter into the human body through food chain, leading to several diseases. Application of metal resistant plant g...

Demand of plant resources especially for food is increasing day by day due to population explosion. To protect plants from pathogen attack both in the field and during storage, several control measures have been adopted. Chemical control, such as use of fungicides has some limitations including environment pollution, residual toxicity and developme...

Rhizobium BICC 651, a fast-growing strain isolated from root nodule of chickpea (Cicer arietinum L.), produced a catechol siderophore to acquire iron under iron poor condition. A Tn5-induced mutant (B153) of the strain, BICC 651 impaired in siderophore biosynthesis was isolated and characterized. The mutant failed to grow on medium supplemented wit...
