Leaf blight caused by Calonectria spp. is one of the most destructive diseases to affect Eucalyptus nurseries and plantations. These pathogens mainly attack Eucalyptus, a tree with a diversity of secondary metabolites employed as defense-related phytoalexins. To unravel the fungal adaptive mechanisms to various phytoalexins, we examined the genome of C. pseudoreteaudii, which is one of the most aggressive pathogens in southeast Asia.

Ribosomally synthesized and post-translationally modified peptides (RiPPs) are a highly diverse group of secondary metabolites (SM) of bacterial and fungal origin. While RiPPs have been intensively studied in bacteria, little is known about fungal RiPPs. In Fungi only six classes of RiPPs are described.

Soil microflora and their diversity study are now modern trends to know the proper soil health. Greater diversity of fungi in soil indicates better health of soil. In this experiment agricultural soil, barren land and garden soil were taken for their micromycoflora study and the diversity of microfungi were analysed by Simpson index and compared among the three types of soil. Total 563 colonies were isolated from the 38 soil samples collected from three different ecosystem types. Sixty eight (68) different species belonging to 31 genera were recorded.

Fungi have diverse biotechnological applications in, among others, agriculture, bioenergy generation, or remediation of polluted soil and water. In this context, culture media based on color change in response to degradation of dyes are particularly relevant; but measuring dye decolorisation of fungal strains mainly relies on a visual and semiquantitative classification of color intensity changes.

Dry root rot caused by Rhizoctonia bataticola (Taub.) Butler is emerging as a serious biotic constraint for chickpea production. It is soil borne fungal pathogen. The losses in chickpea due to Rhizoctonia bataticola may be as high as 60 per cent. The eight isolates of Rhizoctonia bataticola were collected from different districts of Maharashtra. The genomic DNA of 8 isolates of Rhizoctonia bataticola isolated from fresh mycelium of fungus grown in Potato Dextrose Broth solution and subjected to amplification with RAPD marker for diversity analysis.

Through composting process, biosolid wastes are gradually transformed into compost material which can be used as soil fertilizer. Among microorganisms involved in composting process, fungi play important roles because they break down complex substrates, such as ligno-cellulose. Recently, PCR-DGGE technique has been considered as a useful tool for analysis of fungal diversity in environmental samples.

Intra- and interspecific polymorphisms among fungal pathogens that cause wilt and root rot on chickpea were investigated by using 30 RAPD (random amplified polymorphic DNA) and 20 ISSR (inter-simple sequence repeats) primers. UPGMA (unweighted pair group method with arithmetic average) cluster analysis of RAPD and ISSR datasets using Dice’s coefficient differentiated all fungal isolates from each other and revealed considerable genetic variability between the isolates.

Antifreeze proteins are structurally diverse polypeptides that have thermal hysteresis activity and have been discovered in many cold-adapted organ-isms. Of these, fungal antifreeze protein has been purified and partially characterized only in a species of psychrophilic basidiomycete, Typhula ishikariensis.
