“…These proteins may protect hyphae of saprophytes from chitinases released in root exudates [ 54 ], which are present in the rhizosphere. Moreover, Aspergillus oryzae [ 55 ] and A. niger [ 56 ] can behave as endophytes and, as well as saprophytes. A. niger and Neurospora crassa , well-known saprophytes, can also behave as plant pathogens under certain conditions [ 57 , 58 ].…”

Fungal LysM effector proteins can dampen plant host–defence responses, protecting hyphae from plant chitinases, but little is known on these effectors from nonpathogenic fungal endophytes. We found four putative LysM effectors in the genome of the endophytic nematophagous fungus Pochonia chlamydosporia (Pc123). All four genes encoding putative LysM effectors are expressed constitutively by the fungus. Additionally, the gene encoding Lys1—the smallest one—is the most expressed in banana roots colonised by the fungus. Pc123 Lys1, 2 and 4 display high homology with those of other strains of the fungus and phylogenetically close entomopathogenic fungi. However, Pc123 Lys3 displays low homology with other fungi, but some similarities are found in saprophytes. This suggests evolutionary divergence in Pc123 LysM effectors. Additionally, molecular docking shows that the NAcGl binding sites of Pc123 Lys 2, 3 and 4 are adjacent to an alpha helix. Putative LysM effectors from fungal endophytes, such as Pc123, differ from those of plant pathogenic fungi. LysM motifs from endophytic fungi show clear conservation of cysteines in Positions 13, 51 and 63, unlike those of plant pathogens. LysM effectors could therefore be associated with the lifestyle of a fungus and give us a clue of how organisms could behave in different environments.

“…These results were caused by the different nutritional content in each media. PDB is media widely used for fungal growth to produce antibiotics (Margino 2008;Elfita et al 2012). The same situation also happened in the rice washing water used for fungal growth (Thiruvengadam et al 2018).…”

Abstract. Soesanto L, Mugiastuti E, Manan A. 2021. The use of alternative liquid media for propagation of pathogenic fungi and their effect on weeds. Biodiversitas 22: 719-725. Weeds cause high yield losses and are controlled by chemical, physical and mechanical control. Weed pathogenic fungi could be used as a biological control agent. However, the propagation media of them are still a higher cost, therefore, the new alternative and inexpensive media for weed pathogenic fungi propagation are required. The propagation of weed pathogenic fungi in liquid media in-vitro used randomize completely design consisted of three pathogenic weed fungi, i.e., Chaetomium sp., Fusarium sp., and Curvularia lunata and three liquid media, i.e., PDB, rice washing water, and tofu liquid waste. The in-planta tests used split-plot design used weed pathogenic fungi multiplied in the best formula from in-vitro results (rice washing water) and control as the main plot and four weeds, i.e., Cyperus kyllingia, Cynodon dactylon, Portulaca oleracea, and Ageratum conyzoides as subplot. The variables observed were conidia density, incubation period, disease intensity, number of leaves, and weed height. The results showed that rice washing water and tofu liquid waste were suitable media for the propagation of the weed pathogenic fungi. Chaetomium sp. was virulent fungi against broad leaves weeds, especially A. conyzoides. This fungus can be promoted to manufacture organic herbicides against the weed.

“…Results from the detection and identification process showed that Aspergillus niger was the dominant species. This is based on the black colony that grew on the medium (Elfita et al, 2012). Kurniawan et al (2008) reported that Aspergillus niger was one of the fungi isolated from corn seeds.…”

The importation of corn seeds may inadvertently introduce seed-borne fungi like Aspergillus niger. One potential method to control this pathogen was fumigation with sulfuryl fluoride. The objectives of this applied research were to obtain effective concentration and exposure time of sulfuryl flouride as a fumigant to control seedborne fungi and to its physiological impact on corn seeds. Aspergillus niger was isolated from corn seed samples, grew it in potato dextrose agar, and used it for in vitro studies. Parameters observed were isolates’ growth inhibition. In vivo studies were conducted using corn seed samples infected by Aspergillus niger. Sulfuryl fluoride was applied at the concentration of 30, 40, 50, and 60 g/m3 and 24, 48, 72, and 96 hour of exposure time. Results showed that sulfuryl fluoride concentration of 40 g/m3 for 48 hours at 26-32°C is the only effective concentration against A. niger in vitro but all of the treatment did not significantly affect A. niger in vivo. Concentration of 30, 40, 50, 60 g/m3 for 24 hours does not affect the quality of the seed.
