Phialomyces macrosporus decreases anthracnose severity on coffee seedlings by competition for nutrients and induced resistance

Phialomyces Macrosporus Reduces Cercospora Coffeicola Survival on Symptomatic Coffee Leaves

“…saprobes in cucumber plants infected with Pythium ultimum and found that the biocontrol isolates were able to take up the nutrients in the plant tissue more efficiently than was the pathogen, confirming that competition for nutrients is an important mechanism in this biocontrol pathosystem. Rodríguez et al (2016) recently confirmed this hypothesis by determining that the niche overlap index between P. macroscoporus and Colletotrichum gloeosporioides was 100%, i.e., all nutrients the pathogen uses, the biocontrol agent also does and surviving in the necrotrophic tissue provoked by the pathogen.…”

“…Furthermore, they can withstand sudden variations in temperature and humidity and sustain biological control in such environment, which turn them promising biological control agents (Köhl et al, 1995). Currently, saprobe fungi have been used as a biological agent for coffee disease control (Botrel et al, 2018;Rodríguez et al,2016). Therefore, we hypothesize that saprobe fungi might inhibit C. coffeicola growth in crop residues and its production antifungal compounds and cell-wall degrading enzyme may play a role in the pathogen displacement.…”

Phialomyces macrosporus: Chemical Constituents, Antimicrobial Activity and Complete NMR Assignments for the 7,7′‐Biphyscion

“…[35,36] However, this compound is most notably recognized because of its cytotoxicity, teratogenicity and mutagenicity. [37 -40] Since the fungus P. macrosporus is being studied as a promising biocontrol agent in plants of agricultural interest, [15,41] our results suggest that it will be necessary to review this purpose since we detect that this fungus produces a compound with harmful activities and, therefore, its use must be such that it does not cause any risk to the society.

“…One of that microorganism, the fungus Phialomyces macrosporus , was used by us as a template to the production of gold microtubes obtained through the calcination of self‐assembled gold nanoparticles deposited onto its hyphae, as well as MOFs (metal organic framework) . Even though this fungus had been discovered in 1964 by Misra and Talbot, there are few studies on this species and also on this genus, having only one Japanese patent describing six polyketides ( Figure ) that inhibited intercellular adhesion molecule‐1 (ICAM‐1) expression…”

“…[8] One of that microorganism, the fungus Phialomyces macrosporus, was used by us as a template to the production of gold microtubes obtained through the calcination of self-assembled gold nanoparticles deposited onto its hyphae, [9] as well as MOFs (metal organic framework). [10] Even though this fungus had been discovered in 1964 by Misra and Talbot, [11] there are few studies on this species and also on this genus, [12][13][14][15] having only one Japanese patent describing six polyketides ( Figure 1) that inhibited intercellular adhesion molecule-1 (ICAM-1) expression. [16] Therefore, the aims of the present study were to investigate the production of secondary metabolites of P. macrosporus cultivated on sterilized rice and potato dextrose broth and their biological potential, which led to the isolation of the anthraquinone chrysophanol (1), the bianthraquinone 7,7'-biphyscion (2), the ergochrome secalonic acid D (3), the polyol mannitol (4) and the disaccharide trehalose (5) (Figure 2).…”
