“…Among the aerial regions of grass species, the culm followed by leaf harbored most anamorphic and teleomorphic ascomycetes. Similar observations were also made in other studies (Amritha et al 2012;D'souza and Bhat 2013). In addition to this, apart of fungal isolates failed to sporulate by any of the methods tested and such of them were identified as morphotypes or operational taxonomic units (OTUs).…”

Antimicrobial and antioxidant activities and chemical profiling of Curvularia tsudae endophytic in Cynodon dactylon (L.) Pers

There is a growing body of evidence that endophytic fungal metabolites possess important biological activities. Cynodon dactylon (L.) Pers., a well-known grass species with potential medicinal properties, is under-explored for the diversity of endophytic fungal species and their metabolites. We report here the diversity of endophytic fungi in the culm, leaf and inflorescence of Cynodon dactylon when cultured on moist blotter (MB), potato dextrose agar (PDA) and malt extract agar (MEA). Species richness, Shannon and Simpson diversity and evenness indices showed that PDA followed by MEA supported the growth of the largest number of fungal species. Amongst four fungal species tested, Curvularia tsudae was selected for further studies on antimicrobial and antioxidant activities. The mycelial mat (MM) and culture filtrate (CF) of PD broth grown Curvularia tsudae extracted with ethyl acetate and methanol, respectively, were subjected to antimicrobial assay against five bacterial and four fungal test isolates. Results indicated that the ethyl acetate extract of CF had moderate activity against Enterococcus faecalis, Escherichia coli, Pseudomonas fluorescence and Staphylococcus aureus whereas the methanolic MM extract showed high to moderate activity to Aspergillus flavus, A. niger and Fusarium oxysporum. Cyclic voltammetric analysis of ethyl acetate extract showed very good antioxidant activity and the extract contained coumarins when determined by HPLC. High-resolution orbitrap LC-MS of ethyl acetate extract revealed the presence of metabolites with antimicrobial and antioxidant and other biological activities. Finding of the present study suggested that Curvularia tsudae could be exploited for pharmaceutical applications.

“…The mitosporic fungi specifically the class of the Hyphomycota has been considered as the most predominant group in the majority of the plants colonized by the mycoendophytes, it is justified by a lot of studies (Seena and Sridhar 2004;Khan et al 2007;Mangunwardoyo et al 2012;Jena and Tayung 2013;Han et al 2013;Sharma and Kumar 2013;Shi et al 2013;Suciatmih and Rahmansyah 2013;D'souza and Bhat 2013). The nature of dominance of the ISSN 2166-0379 2020 Hyphomycetes can be assigned to their capacity to colonize their host quickly while producing abundant asexual spores (Jena and Tayung 2013).…”

Schinus molle is an arborescent plant that is common in North Africa. It has insecticidal and pharmaceutical activities that are assigned to some active compounds. Harmel is a cosmopolitan species extensively distributed in the world and very common in Algeria especially in the Sahara. This plant is very rich in alkaloids of the β-carbolines group of which most important are harmine. It has pharmaceutical and agrochemical virtues. Endophytic fungi were isolated from aerial part (leaves and fruits) of Peruvian peppertree (S. molle L.) Anacardiaceae and for the first time of the Harmel (Peganum harmala L.) Tetradiclidaceae.Twenty three mycotaxa were identified whose eleven isolated from S. molle and twelve isolated from the second plant. The vast majority are included in mitosporic group (Deuteromycota). The frequency of colonization or infection (FC%) at leaves of the two plants species is significant comparatively to the fruits.

“…In addition to these taxonomic studies, ecological studies were also carried out on litter colonisers and endophytes in plant species from the forests of the Western Ghats in Goa, which included palm trees species, such as Calamus thwaitesii. C. urens, and Elaeis guineensis [433,434].…”

Over the past three decades, a wealth of studies has shown that palm trees (Arecaceae) are a diverse habitat with intense fungal colonisation, making them an important substratum to explore fungal diversity. Palm trees are perennial, monocotyledonous plants mainly restricted to the tropics that include economically important crops and highly valued ornamental plants worldwide. The extensive research conducted in Southeast Asia and Australasia indicates that palm fungi are undoubtedly a taxonomically diverse assemblage from which a remarkable number of new species is continuously being reported. Despite this wealth of data, no recent comprehensive review on palm fungi exists to date. In this regard, we present here a historical account and discussion of the research on the palm fungi to reflect on their importance as a diverse and understudied assemblage. The taxonomic structure of palm fungi is also outlined, along with comments on the need for further studies to place them within modern DNA sequence-based classifications. Palm trees can be considered model plants for studying fungal biodiversity and, therefore, the key role of palm fungi in biodiversity surveys is discussed. The close association and intrinsic relationship between palm hosts and palm fungi, coupled with a high fungal diversity, suggest that the diversity of palm fungi is still far from being fully understood. The figures suggested in the literature for the diversity of palm fungi have been revisited and updated here. As a result, it is estimated that there are about 76,000 species of palm fungi worldwide, of which more than 2500 are currently known. This review emphasises that research on palm fungi may provide answers to a number of current fungal biodiversity challenges.
