Abstract Since the classic studies of Alexander Flemming, Penicillium strains have been known as a rich source of antimicrobial substances. Recent studies have identified novel metabolites produced by Penicillium sclerotiorum that have antibacterial, antifouling and pharmaceutical activities. Here, we report the isolation of a P. sclerotiorum (LM 5679) from Amazonian soil and carry out a culture-based study to determine whether it can produce any novel secondary metabolite(s) that are not thus-far reported for this genus. Using a submerged culture system, secondary metabolites were recovered by solvent extract followed by thin-layer chromatography, nuclear magnetic resonance, and mass spectroscopy. One novel secondary metabolite was isolated from P. sclerotiorum (LM 5679); the phenolic compound 5-pentadecyl resorcinol widely known as an antifungal, that is produced by diverse plant species. This metabolite was not reported previously in any Penicillium species and was only found once before in fungi (that time, in a Fusarium). Here, we discuss the known activities of 5-pentadecyl resorcinol in the context of its mode-of-action as a hydrophobic (chaotropicity-mediated) stressor.

The increasing movement of exotic pathogens calls for systematic surveillance so that newly introduced pathogens can be recognized and dealt with early. A resource crucial for recognizing such pathogens is knowledge about the spatial and temporal diversity of endemic pathogens. Here, we report an effort to build this resource for Pennsylvania (PA) by characterizing the identity and distribution of Phytophthora species isolated from diverse plant species in PA nurseries and greenhouses. We identified 1137 Phytophthora isolates cultured from clinical samples of >150 plant species submitted to the PA Department of Agriculture for diagnosis from 1975 to 2019 using sequences of one or more loci and morphological characteristics. The three most commonly received plants were Abies, Rhododendron, and Pseudotsuga. Thirty-six Phytophthora species identified represent all clades, except 3 and 10, and included a distinct subgroup of a known species and a prospective new species. Prominent pathogenic species such as P. cactorum, P. cinnamomi, P. nicotianae, P. drechsleri, P. pini, P. plurivora, and P. sp. kelmania have been found consistently since 1975. One isolate cultured from Juniperus horizontalis roots did not correspond to any known species, and several other isolates also show considerable genetic variation from any authentic species or isolate. Some species were isolated from never-before-documented plants, suggesting that their host range is larger than previously thought. This survey only provides a coarse picture of historical patterns of Phytophthora encounters in PA nurseries and greenhouses because the isolation of Phytophthora was not designed for a systematic survey. However, its extensive temporal and plant coverage offers a unique insight into the association of Phytophthora with diverse plants in nurseries and greenhouses.

To the best of our knowledge, this is the first report of TCSV infection of H. wayetii and S. truncata from any location, although other tospoviruses are known to infect these and related plant species. The identification of these two diverse plant species as the first reported natural ornamental hosts of TCSV has implications for TCSV epidemiology and management in ornamental and vegetable crops, which frequently share production space.

Has been done Isolation, Characterization and Secondary Metabolite Endophytic Fungal Isolate from Peronema canescens Jack Leave and Coptosapelta tomentosa Valeton K. Heyne Root. The aim of this research is to know the number of fungal isolates, chromatogram profile and secondary metabolite group of endophytic fungal isolates from P. canencens leaves and C. tomentosa root. Characterization of endophytic fungal isolates was done macroscopically and microscopically. Identification of secondary metabolites endophytic fungal isolates were performed by chemical reaction test and TLC (Thin Layer Chromatography) method with specific spray reagents. The data of this study were obtained based on the number of endophytic fungal that can be isolated, observing macroscopic and microscopic morphological profiles, chromatogram profile and secondary metabolites of each endophytic fungal isolated. The results showed that endophytic fungal that can be isolated from P. canencens leaves four isolates, and two isolates from C. tomentosa root. Morphological profile macroscopic endophytic fungal of the six isolates showed a greenish-colored colony, white gray, clear black. Microscopic profile of each fungal isolate having spores, sprangiosphora, sporangium, conidia, hyphae and stolon. The identified secondary metabolites are: alkaloids, terpenoids, and flavonoids, and polyphenols.

The diet of the Pilliga mouse, Pseudomys pilligaensis, was analysed from 430 faecal samples collected from ~340 individuals across different seasons over a period of five years that included a wild fire and subsequent irruption and sharp decline of the population. The primary food items in all seasons were seeds and fruits from diverse plant species, but the mice also consumed a wide range of other foods, including leaves, invertebrates, fungi and mosses. Invertebrates, the second most abundant type of food item, were eaten in all seasons but, with fungi, increased in winter and spring when consumption of seeds and fruits declined. Mice consumed significantly more fungi and mosses before the wild fire than after it. Diets differed between sites rather little in the proportions of food categories, but greatly in the relative proportions of particular seed types in the seed+fruit category. The population irruption could have been triggered by a high reproductive rate that coincided with higher consumption by females of protein-rich foods such as invertebrates and fungi. Population density collapsed at sites as soil stores of utilisable seeds became depleted, mice surviving where their diet could remain diverse.

Tin (Ficus carica) is one of the plants that was mentioned in the Al-Qur’an (at-Tiin 1-3). The plant has the potential of its leaves that can be used as a medicine. In this research were done two tests that are histochemical test and phytochemical test. The method used is descriptive method and the data is processed by descriptive qualitative. Histochemical analysis aims to determine the profile of secondary metabolite compounds in Tin leaf (Ficus carica); among the metabolites were tested the alkaloid, terpenoid, phenol, flavonoid and lipophilic. The second test is the phytochemical test to the examine flavonoid aglycon present, among the tested it  is anthocyanin, flavones, flavonol and, biflavonil by thin layer chromatography method. The result showed that the histochemical analysis of Tin leaf (Ficus carica) contain secondary alkaloid, phenol, flavonoid and lipophilic.

This study aims to determine how to identify the types of secondary metabolite compounds contained in durian leaves. The study was conducted by an experimental method by identifying secondary metabolite compounds on durian leaves using phytochemical screening. The sample criteria used were the leaf buds and all the leaf strands (except the leaf bones). The results of the study showed that of the three types of durian leaves namely copper, baskets and Sp A. There are several types of secondary metabolite compounds including alkaloids, steroids, and terpenoids. Phytochemical screening analysis was carried out using thin layer chromatography by showing RF values on three types of durian leaves using methanol and ethyl acetate solvents in a ratio of 3: 1. RF value on copper durian is 0.97, bakul durian is 0.95 and Sp durian. A 0.94.
