Kavaka Volume 48 (1)

From the Editor's Desk

While releasing the 46 volume of Kavaka being transactions of Mycological Society of India, I promised to add efficiency to the editorial process by initiating online manuscript submission and processing. In the beginning of the year 2017 an independent portal http://www.kavaka.fungiindia.co.in
was started so as to initiate the manuscript processing through open journal system (OJS). With the cooperation of the contributors the editorial office has started receiving manuscripts through this newly started portal. All the manuscripts to be included in Volume 49 scheduled for release in December, 2017 are being processed through open Journal system. The members of Mycological Society of India are requested to avail this facility. For this purpose the website can be assessed either directly or through the portal available on the homepage of the official website of Mycological Society of India (http://www.fungiindia.co.in). Before submitting the manuscript the contributor is required to register which is an obligatory requirement. My sincere thanks are due to all the authors of the articles and the reviewers for their cooperation in various ways without which timely release of the journal would not have been possible.

ABSTRACT
The horizontally transmitted fungal endophytes, especially the members of Ascomycota , establish endosymbiotic relationship with plants of all lineages. Endophytes are universal in their occurrence and have been reported from plants from different habitats. Their ability to elaborate an array of secondary metabolites showing different desirable biological activities has resulted in studying these fungi for technological use. It is imperative that we conduct basic studies to acquire information about the biology of endophytes to harness more profitably their technological traits.

ABSTRACT
This study outlines the pattern of colonization and co-occurrence of saprophytic fungi on woody litter of Avicennia officinalis tree species in Nethravathi mangrove. Two types of woody litter (naturally and artificially submerged) during two seasons (monsoon and summer) were assessed. Natural woody litter consists of 57 fungal species, while it was 34 species in submerged woody litter. Composition of fungi was a mosaic of typical marine and terrestrial fungi. Higher number of fungi (teleomorphs, anamorphs and core-group species) was found in natural than submerged wood, so also during monsoon than summer. Eight species (Aniptodera sp., Lignincola laevis, Lulworthia grandispora, Savoryella lignicola, S. paucispora, Tricladium linderi, Tirispora sp. and Zalerion varia) were common to natural and submerged wood in both seasons. The Shannon diversity was higher during monsoon than summer irrespective of type of wood assessed. The co-occurrence of fungi per wood was maximum up to 8 and 11 species during monsoon in submerged and natural wood, respectively. The pattern of three fungal species co- occurrence was also similar to overall colonization on woody litter. In both wood types, three species co-occurrence was the highest in both seasons. Per cent co-occurrence of 20 core-group species showed dominance in natural than in submerged wood, so also during monsoon than summer. Single species occurrence of core-group fungi on woody litter was as low as 0% (16 core-group fungi on either of wood or season) and 12% (Lignincola laevis). The core-group fungus L. laevis co-occurred up to a maximum of 72% during summer in natural wood which reveals its compatibility and accommodating ability with other associated fungi. Overall, this study reveals that the colonization and co-occurrence of fungi on woody litter in mangroves are dependent on the type of woody litter as well as the monitoring season.

ABSTRACT
In view of application of laccase in bioremediation of textile dyes, a total of six endophytic fungi were isolated from needle of healthy Gymnosperm plant,Cupressus torulosa D. Don of Garhwal, Himalayan region. The colonization rate of these fungi on PDA was higher for various sampling sites in S1 (90) >S2(60) > S3 (40) but colonization rate of fungi in KMM was S3(73) > S1(60)> S2(40). All endophytic fungi were screened for laccase assay as it plays a crucial role in detoxification of toxic dye for human health. Out of six fungi only one endophytic fungus known as KCT34 showed significant laccase activity in solid and liquid media. Initial screening on the malt extract agar plates supplemented with 200 mg L−1 of each Congo red, Rosebangal, Orange G and Rhodamine B dye showed that KCT34 was able to decolorize all of the four dyes. Quantitative analysis of the dye decolorization showed that KCT34 was able to decolorize textile dyes efficiently and dye decolorization percentage was maximum on 16th day with percentage ranging from 90.45% for Congo red, 87.91% for Rose bangal, 85.81% for Orange G and 54.39% for Rhodamine B. Molecular identification of the fungal isolate KCT34 using primer ITS1 and ITS4 showed 99% sequence similarity with Daldinia sp, an Ascomycetous fungus. The ability to decolorize different types of textile dyes by the isolated Daldinia sp. suggested a possible application of fungal endophytes in the decolorization of dyestuff effluents from textile, food and aquaculture industries.

ABSTRACT
Around 30 different mangrove species have been screened for fungal endophytes from different geographical locations that have revealed that the genera of fungi isolated from terrestrial plants are also present in the mangroves, especially, Phomopsis, Phyllosticta, Sporormiella, etc. Species belonging to mangrove Rhizophora from different geographical locations, have been studied for fungal endophytes. Mangrove fungal endophytes have been studied for the production of bioactive compounds, which has resulted in recording of a wide array of compounds having antibiofilm, anticancer, antimicrobial, antioxidant, antiviral and insecticidal activities. An appraisal has been presented on these aspects in this paper.

Keywords: Endophytes, bioactive compounds, mangroves, Rhizophora

ABSTRACT
A nonpathogenic mutant of Botrytis cinerea was obtained by insertional mutagenesis using Agrobacterium tumefaciens mediated transformation. The mutant (Bcnpm) was deficient in expression of a predicted protein unique to B. cinerea. No disease symptoms were observed on tomato plants inoculated with Bcnpm. Bcnpm exhibited reduced ability to penetrate and colonize leaf tissue as compared to its wild type (WT). The concentration of oxalic acid was considerably reduced in Bcnpm. The tomato plants inoculated with Bcnpm provoked lesser oxidative damage in terms of H 2 O 2 production and lipid peroxidation. The magnitude of defence response elicited by Bcnpm was far lesser than that from WT. Bcnpm inoculated plants possessed lower concentration of phenols and reduced activities of defence and antioxidative enzymes. Additionally, qRT-PCR analysis revealed lesser transcript levels of some defence related genes in Bcnpm as compared to WT. It was further observed that pre-inoculation of tomato plants with Bcnpm offered protection to plants challenged with biotic stress. The mechanism behind this protective ability could be induced resistance which might have resulted in priming the plant defence response.
