Kavaka Volume 48 (2)

From the Editor's Desk

The year 2017 mark the centennial year of birth of Late Professor S. B. Saksena of Dr. Hari Singh Gour University, Sagar (M.P.), who has been a legendry mycologist in the league of Late Professor K. S. Thind of Panjab University, Chandigarh and Late Professor C. V. Subramanian of CAS in Botany, Guindy Campus, Chennai. The present issue of Kavaka is dedicated to his memory by Mycological Society of India in honour of the significant contributions made by him to the Indian Mycology, in recognition of which, like his other contemporaries, Dr. Saksena earned international fame. Decision to this effect was taken by the executive of the Mycological Society of India, which was later ratified in the general body meeting of MSI at Jaipur. I take it as a personal pride to be associated with the commemorative volume being released by Mycological Society of India on this auspicious day of the completion of the centennial year of his birth.

The genus Saksenaea was first discovered from India in 1953 from the forest soils of Sagar (Madhya Pradesh) by Late Professor S.B.Saksena of Dr. Hari Singh Gour University, Sagar (M.P.) and named after his Ph.D. supervisor, Prof. R.K.Saksena of Allahabad University, Allahabad. Incidentally the same fungus was discovered by Farrow around this time in 1954 from Barro Colorado Island from the soils of Panama region. The fungus was once thought to be limited in distribution has now been reported from various places from India and abroad. Because of its  unique sporangial characters and non-motile spores in a columellate sporangium it was placed in the order Mucorales of the Division Zygomycota. Ellis and Hesseltine (1974) created a new family Saksenaeaceae for the genus. However, Kirk et al. (2008) have placed the genus in the family Radiomycetaceae. The taxonomic status of the family has been critically evaluated. In 1976, Azello et al published an important paper in which the fungus was found to be serious human pathogen. From 1976 to 2017, more than 50 research papers have been published on the pathogenic nature of the fungus causing severe cutaneous, sub-cutaneous and rhino-orbital-cerebral infections on humans as well as animals. In 2010, Alvarej et al. published a paper based on molecular phylogeny and proposed two more species of this genus. The paper closes with a discussion on the origin of Zygomycetes and the possible origin of Zygomycetes from Chytridiaceous ancestors such as Nowakowskiella whose sporangia look very similar to Saksenaea and also based on biochemical parameters of Chytridiomycetes and Zygomycetes.

KEY WORDS : Saksenaea, Taxonomy, pathogenic aspects and phylogeny.

Fungi represent an important and highly diverse group of eukaryotic microbes on earth. They play a vital role in ecosystem by driving biogeochemical cycling and nutrient uptake eventually influencing the ecological fitness. As compared to bacterial counterpart of microbiome the knowledge about fungi is still lacking from a mycobiome perspective which represents the total fungal biota in the environment. Fungi are widely distributed across all major biomes on earth. However, global fungal diversity patterns are determined by abiotic factors, geographical location, climate change and other environmental factors. With advances in high throughput sequencing platforms fungal biodiversity has been unraveled at a greater depth. This has shed light on fungal community dynamics and its contrasting features from microbiome perspectives. Additionally, a growing body of evidence suggests inter and intra-kingdom interactions and possible role of mycobiome as an integral part of the human welfare. In this article, the mycobiome is discussed in context of its association and significance in major biomes of earth.

Keywords: Fungi, biomes, next generation sequencing, mycobiome, microbiome

Fresh bark pieces of Mimusops elengi Linn. were used for the isolation of fungal endophytes using standard methods. Mimusops elengi is a small to a large evergreen medicinal plant found all over the different parts of India. Seventy one endophytic fungi belonging to ascomycetes (11.27%), coelomycetes (39.44%) and hyphomycetes (49.29%) were isolated from 200 segments of Mimusops elengi collected from Dr. H. S. Gour University campus in Sagar District, Madhya Pradesh, India. The identification of these fungi was confirmed by the BLAST search of sequences of the ITS1-5.8S-ITS2 rDNA region against the NCBI/GenBank data and compared with deposited sequences for identification purpose. Sixteen different fungal species belonging to 16 genera viz. Botryosphaeria mamane, Chaetomium globosum, Rhytidhysteron sp., Phoma putaminum, Pestaliopsis sp., Colletotricum gleosporoides, Phomopsis sp., Acremonium sp., Alternaria alternata, Beltraniella portoricensis, Cladosporium cladosporioides, Curvularia lunata, Fusarium chlamydosporum, Myrothecium verrucaria, Nigrospora oryzae and Torula herbarum were isolated. The most frequently isolated endophytes were Cladosporium cladosporioides (22.53%), Pestaliopsis sp.,(19.71%), Phomopsis sp., (9.86%) and Chaetomium globosum (8.45%). This study shows that a great number of endophytic fungi exist in the samples obtained from bark samples of M. elengi.

Key words: Fungal endophytes, bark samples, Mimusops elengi, medicinal plants.

Twenty three species belonging to ten genera of fungi were isolated by two methods from three saltern soils of southern India. Species of Aspergillus were the most common fungi present in these samples. Three of these fungi, viz. Aspergillus sp. 3, A. terreus, and a sterile fungus (SF2) were further studied for their salt tolerance, production of some extracellular enzymes and bioactive metabolites as influenced by external salt concentration. The fungi were halotolerant and not halophilic and two of them could grow on 20% NaCl medium. Extracellular enzyme production was influenced by salt in these fungi. Some enzymes were produced through a range of salt concentration (0 to 18 %), some enzymes showed more activity in the presence of salt and a few enzymes were salt-induced. Antialgal and antifungal metabolites were elaborated only in the presence of salt.

KEY WORDS : Extremozymes, halotolerant, salt tolerant fungi

Phosphorus is an important nutrient required for plant growth, yield and adaptability to different ecological conditions. Many Indian soils are  deficient in phosphorus. The organic form of available phosphorus is meagre and mineral phosphorus such as rock phosphate is found in large quantities. The mineral phosphorus needs to be solubilized by varied groups of microorganisms, thus making 'P' available for crop plants and forestry. This review presents information on role of phosphate solubilizing fungi and microbes for sustainable agriculture and agro-forestry.

KEYWORDS: Agriculture, agroforestry, fungi, microbes, phosphorus, rock phosphate.

Thermophilic moulds are capable of degrading plant organic residues at elevated temperatures by secreting a large array of hydrolases. These moulds produce cellulolytic enzymes in submerged as well as solid substrate fermentations. Cellulases from these moulds have been characterized, which display a high thermostability, catalytic activity and fast rate of reactions as compared to their mesophilic counterparts. Their optimal activities lie in the range of 50-70 o C and pH of 3.0-6.0 with molecular masses between 40 and 240 kDa. The genes encoding cellulolytic enzymes of the moulds have been cloned and expressed in both homologous and heterologous systems. Cellulolytic enzymes of thermophilic moulds have been shown to be efficient in plant biomass degradation. The applicability of cellulases in a number of biotechnological processes such as the production  of biofuels, food and animal feeds, detergents and paper pulp processing has been demonstrated.

Seasonal occurrence of marine ascomycetes and anamorphic marine fungi in mangroves of Godavari and Krishna deltas, East coast of India was studied. The results showed more percentage occurrence of ascomycetes during dry period and more anamorphic fungi during wet period and converse was true in dry and wet periods for respective groups where the percentage occurrence was less than the usual. Among the various environmental factors studied such as maximum and minimum air temperatures, relative humidity, salinity, surface water temperature and average monthly rainfall only average monthly rainfall showed an effect on the species richness and abundance of ascomycetes and anamorphs. No or low rain fall favored higher percentage of ascomycetes and a good rainfall has favored an increase in the anamorphic fungi and a decrease in ascomycetes.

Key words: Seasonality, Ascomycetes, anamorphic marine fungi, Rhizophora spp., Avicennia spp.

The discipline 'aquatic hyphomycetology' with exciting historical background addresses the biology and ecology of a specific group of mycota adapted to stream ecosystems. The major attractions of these fungi are production of characteristic conidia (mainly staurosporous and scolecosporous) and wide geographic distribution. Their important ecological functions include breakdown and mineralization of plant lignocellulosic substrata and the transfer of energy to higher trophic levels in streams. The global proportion of life sustaining freshwater amounts to 2.75% with only 0.01% present as surface water in diverse habitats. Therefore, occurrence, distribution and role of aquatic hyphomycetes in freshwater food webs are of immense significance. In addition to field studies in streams, these fungi serve as model community for mesocosm and microcosm experiments to address many ecological issues. Many species of aquatic hyphomycetes remain unknown and are yet to be explored.
There are many unsettled questions on their occurrence, distribution, adaptations and functions. In the current global scenario (climate change, global warming and pollution), the role of aquatic hyphomycetes in streams is highly valuable to understand their ecosystem services to enforce conservation strategies. This contribution is a general account of the inventory, approaches, boundaries, ecological services and future challenges concerning aquatic hyphomycetes.
