“…Interestingly, two VOCs, methyl prop-2-enoate (MA) and methyl propionate (MP), exhibited significant antifungal activities. These molecules inhibited fungal growth by more than 81% for both fungi [14]. Despite the unique ability of methyl prop-2-enoate (MA) and methyl propionate (MP) to inhibit a large spectrum of pathogens, their mechanisms of action still remains poorly studied.…”

This study evaluated the antifungal effects of various volatile organic compounds (VOCs) against two common pathogens: Fusarium culmorum and Cochliobolus sativus. Among the various VOCs, methyl propanoate (MP) and methyl prop-2-enoate (MA) exhibited remarkable antifungal effects under different experimental conditions (direct or indirect contact) and at different concentrations (500–1000 μM). In addition, the type of antifungal effect (fungistatic or fungicidal) appeared to be strongly correlated with the VOC concentrations. Additional tests revealed that both molecules increased membrane permeability of pathogenic spores, which resulted in a decreased efflux of K+ ions into the intracellular medium.

“…Among them, compounds with cytotoxic capacity against cancer cells and other diseases, such as taxol, podophyllotoxin, camptothecin, and vinca alkaloids have also been found (Gouda et al, 2016;Uzma et al, 2018). But, they are also capable of producing various mixtures of carbon-based compounds, which are known as volatile organic compounds (VOCs) with a direct application as pesticides (Kaddes et al, 2019).…”

Biological Control of Plant-Parasitic Nematodes by Filamentous Fungi Inducers of Resistance: Trichoderma, Mycorrhizal and Endophytic Fungi

2020

Plant-parasitic-nematodes represent a major threat to the agricultural production of different crops worldwide. Due to the high toxicity of chemical nematicides, it is necessary to develop new control strategies against nematodes. In this respect, filamentous fungi can be an interesting biocontrol alternative. The genus Trichoderma, mycorrhizal and endophytic fungi are the main groups of filamentous fungi studied and used as biological control agents (BCAs) against nematodes as resistance inducers. They are able to reduce the damage caused by plant-parasitic nematodes directly by parasitism, antibiosis, paralysis and by the production of lytic enzymes. But they also minimize harm by space and resource-competition, by providing higher nutrient and water uptake to the plant, or by modifying the root morphology, and/or rhizosphere interactions, that constitutes an advantage for the plant-growth. Besides, filamentous fungi are able to induce resistance against nematodes by activating hormone-mediated (salicylic and jasmonic acid, strigolactones among others) plant-defense mechanisms. Additionally, the alteration of the transport of chemical defense components through the plant or the synthesis of plant secondary metabolites and different enzymes can also contribute to enhancing plant defenses. Therefore, the use of filamentous fungi of the mentioned groups as BCAs is a promising durable biocontrol strategy in agriculture against plant-parasitic nematodes.

“…from C. sinensis include several sesquiterpenes, namely azulene, cis/trans-α-bergamotene, cedrene, (Z)-β-farnesene, farnesene epoxide, α-himachalene, α-longipinene, thujopsene, 2,4,6-trimethyl-1,3,6-heptatriene, 2-methyl-5,7-dimethylene-1-8-nonadiene, and cis-Z-bisabolene epoxide [61]. Mixtures of these compounds have a possible biotechnological application for the mycofumigation of fruits, proposed for the control of CBS and various post-harvest pathogens [90][91][92]. Concerning VOCs, another possible investigational subject consists in assessing if any endophyte of citrus plants is able to produce compounds occurring in the typical aroma spread by flowers and fruits of these plants, which are exploited by the pharmaceutical and the perfume industries.…”

Endophytic Fungi of Citrus Plants

Besides a diffuse research activity on drug discovery and biodiversity carried out in natural contexts, more recently, investigations concerning endophytic fungi have started considering their occurrence in crops based on the major role that these microorganisms have been recognized to play in plant protection and growth promotion. Fruit growing is particularly involved in this new wave, by reason that the pluriannual crop cycle likely implies a higher impact of these symbiotic interactions. Aspects concerning occurrence and effects of endophytic fungi associated with citrus species are revised in the present paper.Agriculture 2019, 9, 247 2 of 13 similar but fast-growing, and producing conidia embedded within a thicker mucoid sheath [4][5][6][7][8]. The latter, characterized as a different species (Phyllosticta capitalensis), are known to be ubiquitous as endophytes in woody plants, having been reported from at least 70 botanical families [6,9,10]. Guignardia endophyllicola, treated as a separate species in a work also emphasizing its widespread endophytic occurrence [11], is at present recognized as a synonym. Differences between the two sister species also concern their metagenetic cycle. In fact, it has been ascertained that P. citricarpa is heterothallic, while P. capitalensis is homothallic [8]. This consolidated taxonomic distinction supports the exclusion from quarantine measures of plant material harbouring P. capitalensis. To this purpose, several rapid PCR assays have been developed [12][13][14][15][16][17][18][19][20]. The applicative use of these assays has enabled to exclude the presence of the pathogen in New Zealand, unlike what was previously assumed [21], and has supported the hypothesis of the possible endophytic occurrence of P. citricarpa in asymptomatic Citrus spp., as pointed out by several investigations (Table 1). Moreover, the two species have been clearly differentiated on account of their enzymatic profiles, with a higher expression of amylases, endoglucanases, and pectinases in P. citricarpa, suggesting a likely involvement of these enzymes in the pathogenic aptitude of the CBS agent [22]. Differences in terms of pathogenesis-related proteins have been confirmed after the genome sequencing of the two species, disclosing a higher number of coding sequences in P. citricarpa (15,206 versus 14,797). Such a difference has been interpreted considering the presence of growth and developmental genes involved in the expression of pathogenicity [23].The issue of detection of contaminated material imported from areas where the pathogen is endemic has also prompted investigations concerning the assortment of Phyllosticta spp. able to colonize citrus plants in either symptomatic or latent courses. Several revisions have been published [17,24], and novel species characterized, which consistently enlarge the citrus-associated consortium within this widespread genus. Particularly, the pathogenic P. citriasiana from south-east Asia [25], P. citrichinaensis from China [26], P. citrimaxima from Thailand...
