“…In this work, we examined both the endophytic and epiphytic fungal populations in the orchid to fully consider the great microbiological richness associated to this plant. We found that the leaf was the tissue with the greatest diversity of epiphytes, while the root exhibited the highest diversity of endophytic genera, in accordance with the significant microbial interactions that occur in these plant tissues and with previous reports (Vendramin et al, 2010 ; Sudheep and Sridhar, 2012 ; Bunch et al, 2013 ; Chen et al, 2013 ). However, we also found that other tissues like the pseudobulb showed a considerable diversity for both epiphytic and endophytic isolates, supporting the notion that other tissues should also be considered in this type of studies.…”

“…In this study we identified 63 genera, 30 of which have already been reported as orchid endophytes (McCormick et al, 2004 ; Albores et al, 2005 ; Chen et al, 2011 ; Jiang et al, 2011 ; Sudheep and Sridhar, 2012 ; Sawmya et al, 2013 ; Tao et al, 2013 ). Some of these endophytes have shown beneficial effects, like the antibacterial activity of Alternaria sp.…”

Stanhopea tigrina is a Mexican endemic orchid reported as a threatened species. The naturally occurring microorganisms present in S. tigrina are unknown. In this work, we analyzed the diversity of endophytic and epiphytic culturable fungi in S. tigrina according to morphological and molecular identification. Using this combined approach, in this study we retrieved a total of 634 fungal isolates that presented filamentous growth, which were grouped in 134 morphotypes that were associated to 63 genera, showing that S. tigrina harbors a rich diversity of both endophytic and epiphytic fungi. Among these, the majority of the isolates corresponded to Ascomycetes, with Trichoderma and Penicillium as the most frequent genera followed by Fusarium and Aspergillus. Non-ascomycetes isolated were associated only to the genus Mucor (Mucoromycota) and Schizophyllum (Basidiomycota). Identified genera showed a differential distribution considering their epiphytic or endophytic origin, the tissue from which they were isolated, and the ability of the orchid to grow on different substrates. To our knowledge, this work constitutes the first study of the mycobiome of S. tigrina. Interestingly, 21 fungal isolates showed the ability to produce gibberellins. Almost half of the isolates were related to the gibberellin-producer genus Penicillium based on morphological and molecular identification. However, the rest of the isolates were related to the following genera, which have not been reported as gibberellin producers so far: Bionectria, Macrophoma, Nectria, Neopestalotiopsis, Talaromyces, Trichoderma, and Diplodia. Taken together, we found that S. tigrina possess a significant fungal diversity that could be a rich source of fungal metabolites with the potential to develop biotechnological approaches oriented to revert the threatened state of this orchid in the near future.

Endophytic fungi associated with roots of epiphytic orchids in two Andean forests in Southern Ecuador and their role in germination

et al. 2020

Orchids are known to establish complex relationships with endophytic fungi throughout their life cycle, and particularly during germination of their reserves-deprived seeds. Characterizing generalist or specialist interactions between orchids and associated fungi is key to supporting orchid conservation efforts. Here, endophytic fungi associated with roots of epiphytic orchids were studied in two montane Andean forests in Southern Ecuador. Orchid root samples were collected from ten ~500 m2 plots distributed between two neighboring forests. Endophytic fungi associated with these roots were then isolated, cultured, and identified by sequencing of rDNA markers. In total, 52 pure isolates were recovered from the roots of 10 orchid species. These isolates were classified into nine taxonomic groups except for one isolate that remained unclassified. Most fungal isolates were found in roots of up to two different orchid species; however, Coprinellus radians was found in the roots of all sampled orchids. The potential of C. radians to promote germination of orchid seeds was tested in a separate assay using seeds from two orchid species different than those found in the experimental forest plots. Of the two C. radians isolates tested, one improved germination in the two orchids evaluated to a level about half of that observed in seeds germinated in nutrient-rich medium (Phytamax) and above the null germination observed in plates without the fungus. Together, these results revealed a generalist relationship between C. radians and all the studied epiphytic orchids and the potential role of this fungus as a promoter of orchid seed germination. Key Words: Agaricales, Epidendrum, symbiotic germination

Pohon asam (Tamarindus indica) sangat sesuai untuk peneduh dan lanskaping karena bentuk tajuknya rindang, daunnya kecil-kecil, rantingnya kuat dan tidak mudah patah. Tujuan dari penelitian ini adalah untuk mengetahui populasi pohon asam di sepanjang Jl. Raya Socah-Arosbaya, Kabupaten Bangkalan. Survei dilaksanakan pada Juni-Agustus 2018 dengan metode purposive sampling mulai dari jalan raya Socah dengan koordinat 7°05'48.6"LS 112°42'44.3"BT sampai Jalan raya Gebang Arosbaya yang berada di koordinat 6°58'57.3"LS 112°47'38.0"BT. Hasil penelitian menunjukkan populasi pohon asam sepanjang Jl. Raya Socah-Arobaya hanya ada 102 tanaman (5.03%) dengan indeks biodiversitas sebesar 0.1509. Pohon asam perlu dilestarikan karena selain bernilai sejarah juga sebagai tempat endemik anggrek Vanda limbata dan kepentingan penelitan biologi di lahan kering.Kata Kunci: Bangkalan, indeks biodiversitas, peneduh, pohon asam, Tamarindus indicaPopulation Diversity of tamarind (Tamarindus indica L.) populations in Socah-Arosbaya Highway, Bangkalan District and Conservation Strategies ABSTRACTThe tamarind tree (Tamarindus indica) is very suitable for shade and landscape because the the canopy is shady, the leaves are small, the branches are strong and not easily broken. The purpose of this study was to determine the tamarind tree population along Socah-Arosbaya highway, Bangkalan district. The survey was done in June-August 2018 with purposive sampling method, starting from Socah highway with coordinates 7°05'48.6"S 112°42'44.3"E to Gebang Arosbaya highway located at coordinates 6°58'57.3"S 112°47'38.0"E. The results showed the tamarind tree population along Socah-Arobaya highway there are only 102 plants (5.03%) with a diversity index was 0.1509. Tamarind trees need to be conserved because in addition to historical value as well as a place of Vanda limbata orchids and the importance of biological research on dry land.
