Pestalotiopsis sensu lato , commonly referred to as pestalotiopsis-like fungi, exhibit a broad distribution and are frequently found endophytes, saprobes pathogens across various plant hosts. The taxa within fungi classified into three genera viz. Pseudopestalotiopsis Neopestalotiopsis based on the conidial colour of their median cells multi-locus molecular phylogenies. In course biodiversity investigation focusing total 12 fungal strains were identified. These be associated with stromata Beauveria Ophiocordyceps Tolypocladium in regions Taiwan from 2018 2021. evaluated morphologically phylogenetic analyses ITS (internal transcribed spacer), tef1-α (translation elongation factor 1-α) tub2 (beta-tubulin) gene conducted for genotyping. results revealed seven well-classified one tentative clade . One novel species, manyueyuanani four new records, N. camelliae-oleiferae haikouensis P. chamaeropis hispanica reported first time Taiwan. addition, formosana an unclassified strain identified, similarities phylogeny morphology. However, data obtained present study suggest that currently recommended loci species delimitation do not deliver reliable or adequate resolution tree topologies. in-vitro mycelial growth rates selected these had optimum temperature 25 °C, but ceased at 5 °C 35 while all grew faster under alkaline than acidic neutral pH conditions. This provides assessment entomopathogenic taxa.

Опубликована: Май 24, 2023

During our investigations of the microfungi on medicinal plants in Thailand, five isolates Diaporthe were obtained. These identified and described using a multiproxy approach, viz. morphology, cultural characteristics, host association, multiloci phylogeny ITS, tef1-α, tub2, cal, his3, DNA comparisons. Five new species, afzeliae, D. bombacis, careyae, globoostiolata, samaneae, are introduced as saprobes from plant hosts, Afzelia xylocarpa, Bombax ceiba, Careya sphaerica, member Fagaceae, Samanea saman. Interestingly, this is first report species these plants, except Fagaceae member. The morphological comparison, updated molecular phylogeny, pairwise homoplasy index (PHI) analysis strongly support establishment novel species. Our also revealed close relationship between zhaoqingensis chiangmaiensis; however, evidence PHI test comparison indicated that they distinct findings improve existing knowledge taxonomy diversity well highlight untapped potential for searching fungi.

Novel endophytic pestalotioid species associated with Itea in Thailand

Frontiers in Cellular and Infection Microbiology, Год журнала: 2025, Номер 15

Опубликована: Апрель 3, 2025

Endophytic fungi are a well-known fascinating host-associated fungal group that can enhance plant growth and fitness by producing various bioactive secondary metabolites. They an excellent source of industrial enzymes for potential metabolite synthesis, which is useful in green agriculture, biotechnology, pharmaceuticals. Itea valuable genus since it naturally contains rare sugar; however, endophytic associated this host have not yet been documented. In the present study, 11 strains were isolated primarily identified as pestalotioid taxa based on morphological characteristics exhibited vitro. Eleven Pestalotiopsis-like from healthy leaves, stems, roots japonica I. riparia Chiang Mai Province, Thailand. Species delimitation was morphology, multiloci phylogeny concatenated ITS, tub2, tef1-α sequence data, nucleotide polymorphism analyses. Neopestalotiopsis iteae Pseudopestalotiopsis proposed new species riparia, respectively. chrysea, N. haikouensis, Pestalotiopsis jinchanghensis described records riparia. Owing to conspecific relationship identically pairwise comparison sufficient gene regions, several synonymized including cercidicola terricola umbrinospora zhaoqingensis P. jinchanghensis. The updated phylogenetic trees, comparisons, descriptions herein provided discussed taxonomic placements these records. This study first investigate endophytes Thailand, reveals intra- interspecific relationships species, need be further reevaluated because ambiguous taxa.
