Appl Microbiol Biotechnol 2022; 106:2927-2935. [PMID: 35416486 DOI: 10.1007/s00253-022-11914-1] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Revised: 03/30/2022] [Accepted: 04/02/2022] [Indexed: 02/06/2023]
Abstract
A new meroterpenoid, taladrimanin A (1), was isolated from a marine-derived fungus Talaromyces sp. HM6-1-1, together with eleven biogenetically related compounds (2-12). A plausible biosynthetic pathway for the meroterpenoids (1-4) was proposed. The planar structure of 1 was assigned by HRESIMS and NMR. Its relative configuration was established by quantum chemical NMR calculation of two possible isomers and analyzed by DP4 + method. Finally, X-ray diffraction unambiguously confirmed the relative configuration and revealed the absolute configuration of compound 1. 2-12 were assigned by comparing their NMR data with those reported in the literature. 1 was the first drimane-type meroterpenoid with a C10 polyketide unit bearing an 8R-configuration. In the bioactive assay, 1 exhibited antitumor activity against gastric cancer cells MGC803 and MKN28; it also inhibited the colony formation and induced apoptosis in MGC803 cells both in a concentration-dependent manner. Additionally, 1 displayed selective antibacterial activity against Staphylococcus aureus 6538P, and low activities towards strains of Vibrio parahaemolyticus and Escherichia coli in this study. KEY POINTS: • Twelve compounds were obtained from Talaromyces sp., including four meroterpenoids, one of which was new. • The new compound taladrimanin A (1) inhibits the growth of gastric cancer cells MGC803 and MKN28 as well as the pathogenic bacteria Staphylococcus aureus 6538P. • The biosynthetic pathway of the meroterpenoids was proposed.

Endophytic Colonization by the Entomopathogenic Fungus Beauveria Bassiana Affects Plant Volatile Emissions in the Presence or Absence of Chewing and Sap-Sucking Insects. FRONTIERS IN PLANT SCIENCE 2021; 12:660460. [PMID: 34381470 PMCID: PMC8350324 DOI: 10.3389/fpls.2021.660460] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/29/2021] [Accepted: 06/11/2021] [Indexed: 05/31/2023]
Abstract
Entomopathogenic fungi are gaining acceptance in Integrated Pest Management (IPM) systems as effective and environmental safety biological control agents to protect a great variety of crops against pest insects. Many of these insect-pathogenic fungi can establish themselves as endophytes and thereby may induce the plant immune system. The activation of plant defenses by the fungal endophytic colonization can have a direct impact on herbivores and plant pathogens. An integral component of many plant defense responses is also the release of volatile organic compounds, which may serve as an indirect defense by attracting the natural enemies of herbivores. Here we investigated the effect of endophytic colonization by the entomopathogenic fungus Beauveria bassiana on the volatile emission by melon and cotton plants, either unharmed or after being damaged by sap-sucking aphids or leaf chewing caterpillars. We found that when the plants are colonized by B. bassiana they emit a different blend of volatile compounds compared to uncolonized control plants. Some of the emitted compounds have been reported previously to be released in response to herbivory and have been implicated in natural enemy attraction. Several of the compounds are also known to have antimicrobial properties. Therefore, endophytic colonization by B. bassiana might help to not only direct control insect pests but also increase the resistance of plants against agronomically important pests and phytopathogens.

Abstract
Covering: up to April 2020Fungal benzene carbaldehydes with salicylaldehydes as predominant representatives carry usually hydroxyl groups, prenyl moieties and alkyl side chains. They are found in both basidiomycetes and ascomycetes as key intermediates or end products of various biosynthetic pathways and exhibit diverse biological and pharmacological activities. The skeletons of the benzene carbaldehydes are usually derived from polyketide pathways catalysed by iterative fungal polyketide synthases. The aldehyde groups are formed by direct PKS releasing, reduction of benzoic acids or oxidation of benzyl alcohols.
