Abstract
Penicillium setosum represents a Penicillium species recently described, with little up-to-date information about its metabolic and biological potential. Due to this scenario, we performed chemical and biological studies of P. setosum CMLD18, a strain isolated from Swinglea glutinosa (Rutaceae). HRMS-MS guided dereplication strategies and anti-leukemia assays conducted the isolation and characterization of six compounds after several chromatographic procedures: 2-chloroemodic acid (2), 2-chloro-1,3,8-trihydroxy-6- (hydroxymethyl)-anthraquinone (7), 7-chloroemodin (8), bisdethiobis(methylthio)acetylaranotine (9), fellutanine C (10), and 4-methyl-5,6-diihydro-2H-pyran-2-one (15). From the assayed metabolites, (10) induced cellular death against Kasumi-1, a human leukemia cell line, as well as good selectivity for it, displaying promising cytotoxic activity. Here, the correct NMR signal assignments for (9) are also described. Therefore, this work highlights more detailed knowledge about the P. setosum chemical profile as well as its biological potential, offering prospects for obtaining natural products with anti-leukemia capabilities.

Zubairi T, Jabeen K, Khalid S, Iqbal S. Isolation and molecular characterization of causal agent of blue mold on Allium cepa L. and its control by Pennisetum flaccidum Griseb. Saudi J Biol Sci 2021; 28:6774-6781. [PMID: 34866976 PMCID: PMC8626295 DOI: 10.1016/j.sjbs.2021.07.050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Revised: 07/13/2021] [Accepted: 07/16/2021] [Indexed: 12/02/2022] Open
Abstract
Blue mold pathogen, isolated from infected Allium cepa L., was identified as a Penicillium species through morphological and molecular characterisation. Internal Transcribed spacer (ITS) region of ribosomal DNA (rDNA) was utilised for DNA sequencing. Basic Local Alignment Search Tool (BLAST) analysis has found the maximum similarity index of the fungus to be 82.39% with the Uncultured Penicillium clone (Accession: MF535522). So, the isolated Penicillium specie is the first reported specie of the genus that infects onion. A phylogenetic tree was constructed to establish a relationship of the isolated fungus with the most relevant species reported on GenBank. Extracts of Pennisetum flaccidum Griseb. were evaluated against the isolated fungus as a potential biocontrol agent. Among the five tested methanol concentrations (0.5%, 1%, 1.5%, 2% and 2.5%) of each plant part (root, inflorescence and foliage), 0.5% root extract showed maximum growth retardation, i.e. 89%. For bioassay-guided fractionation, the root extract was partitioned in n-hexane, chloroform, n-butanol and ethyl acetate. Ethyl acetate (1%) was proved to be the most potent one. Phytochemical screening has confirmed the occurrence of terpenoids, tannins, saponins and alkaloids. The applied molecular approach has deduced that the Penicillium specie collected from Pakistan might be novel. This study can be concluded that P. flaccidum contains potent phytochemicals which might be used as antifungal agent against Penicillium species.

Abstract
A Penicillium species isolated during a 1960s study on the ecology of fungi infecting Pinus radiata timber, and subsequently held in an in-house collection in Rotorua, New Zealand, was found to differ morphologically and in growth rate from two closely related Penicillium species. Phylogenetic analysis of the rDNA internal transcribed spacer (ITS), β-tubulin, calmodulin and RNA polymerase II second largest subunit regions (RPB2) confirmed this to be a new species closely related to Penicillium ochrochloron in the Rolfsiorum series of the Lanata-Divaricata section and Aspergilloides sub-genus. Micromorphologically, the new species is characterised by predominantly monoverticilliate and occasional divaricate or biverticilliate conidiophores and smooth-walled subglobose to slightly ovoid conidia with absence of conidiogenesis at 25 °C. This new species is described here as Penicillium rotoruae sp. nov. which has potential applications in biofuel and biorefining industry.

Abstract
In the present study, secondary metabolites produced by an endophytic fungus Penicillium setosum were extracted using colony agar plug and culture broth extraction methods. High resolution LC-MS was used to explore the chemical nature of the secondary metabolites, as well, compare the reliability of the methods. P. setosum was chemotaxonomically distinguished from other members of section Lanata-divaricata, by its ability to produce mycotoxin, patulin and also by the presence of certain phenol-derived compounds, like quercetin, dihydroflavonols (dihydroquercetin and dihydromyricetin), kaempferol, luteolin, while some Penicillium specific compounds such as, citromycetin and andrastin D reveal its similarity towards section Lanata-Divaricata members. For the first time, the presence of dihydroquercetin is remarkably and spectrometrically confirmed from a microbial source. In addition, a few polyketides, anthroquinone compounds, hydrocarbons, and fatty acids were also detected in the culture extract. Being the first report on the production of polyphenolic compounds by an endophytic fungus of Penicillium species, the current research is crucial, and moreover the starin itself is a novel species.
