Effect of biotic and abiotic stresses on volatile emission of Achillea collina Becker ex Rchb

This study describes the application of headspace solid-phase microextraction (HS-SPME)-gas chromatography/mass spectrometry (GC/MS) to characterise the volatile fingerprint changes of Achillea collina, induced by aphids' infestation, mechanical damage and jasmonic acid (JA) treatment. The volatile organic compound profiles of A. collina, Prunus persica and Pisum sativum infested by Myzus persicae were also compared. Several changes were observed between control, infested, mechanically damaged and JA-treated plants, and new inducible volatile organic compounds (IVOCs) were emitted in response to biotic or abiotic stresses. Some of these were in common for all stresses and other compounds were in common only for two types of stress. Conversely some IVOCs were emitted only in response to the specific stimuli. The results suggested that there were species-specific and common IVOCs emitted by A. collina, P. persica and P. sativum in response to M. persicae infestation. In conclusion, HS-SPME-GC/MS seems to be a reliable analytical approach to study in vivo plant reaction to external stimuli

Multi-Gene Phylogeny and Morphology Reveal Haplohelminthosporium gen. nov. and Helminthosporiella gen. nov. Associated with Palms in Thailand and A Checklist for Helminthosporium Reported Worldwide

Palms (Arecaceae) are substrates for a highly diverse range of fungi. Many species are known as saprobes and many are important plant pathogens. Over the course of our studies of micro-fungi from palms in Thailand, two new taxa were discovered. Morphological characteristics and phylogenetic analyses of combined ITS, LSU, SSU, and tef1-α sequence data revealed their taxonomic positions within Massarinaceae. There are currently ten genera identified and accepted in Massarinaceae, with the addition of the two new genera of Haplohelminthosporium and Helminthosporiella, that are introduced in this paper. Each new genus is provided with a full description and notes, and each new taxon is provided with an illustration for the holotype. A list of identified and accepted species of Helminthosporium with morphology, host information, locality, sequence data, and related references of Helminthosporium reported worldwide is provided based on records in Species Fungorum 2021. This work provides a micro-fungi database of Haplohelminthosporium, Helminthosporiella, and Helminthosporium which can be modified and validated as new data come to light

Checklist, typification details, and nomenclature status of ascomycetous fungi originally described in Sri Lanka.

Despite being a biodiversity-rich country, Sri Lanka’s fungal diversity remains largely unexplored. In the 19th century, British mycologists conducted extensive research, leading to the identification of more than 1,800 fungal taxa, including ascomycetous and basidiomycetous species. However, the majority of these taxa have not been revisited since their initial description, and molecular evidence is lacking. Moreover, a significant number of fungal taxa have been deemed invalid or illegitimate, indicating the need for a nomenclatural revision. To address this knowledge gap, this review provides a comprehensive list of ascomycetous taxa (including both lichen-forming and non-lichenized) that were originally described in Sri Lanka. Names are listed according to the original names which were included in the protologue. In the cases where species have been transferred to other genera, the current names and new classifications are provided. The typification details, nomenclature status, and classification are also presented. This checklist will serve as a valuable resource for the future epitypification of old taxa, as much of the existing information is poorly documented and scattered

Serpulanines A to C, N‑Oxidized Tyrosine Derivatives Isolated from the Sri Lankan Fungus <i>Serpula</i> sp.: Structure Elucidation, Synthesis, and Histone Deacetylase Inhibition

Serpulanines A (<b>1</b>), B (<b>2</b>), and C (<b>3</b>) have been isolated from extracts of the rare Sri Lankan macrofungus <i>Serpula</i> sp. The structures of <b>1</b>, <b>2</b>, and <b>3</b> were elucidated by a combination of spectroscopic and single-crystal X-ray diffraction analyses. Serpulanines A (<b>1</b>) and B (<b>2</b>) both contain the rare (<i>E</i>)-2-hydroxyimino hydroxamic acid functional group array. A proposed biogenesis for serpulanine B (<b>2</b>) suggests that its (<i>E</i>)-2-hydroxyimino hydroxamic acid moiety arises from a diketopiperazine precursor. Synthetic serpulanine A (<b>1</b>) inhibited class I/II histone deacetylases in murine metastatic lung carcinoma cells with an IC₅₀ of 7 μM
