Among the 2–13 amino acids located between the two CXC motifs, there may be other Cys and/or His residues (Fig. Mucor is a genus of fungi that consists of approximately 50 species [1]. ADVERTISEMENTS: Coenocytic fungi which lack motile cells and produce zygospore as the sexual spore are placed under phylum Zygomycota. Scer, Saccharomyces cerevisiae; Spom, Schizosaccharomyces pombe; Cort, Candida orthopsilosis; Calb, Candida albicans; Cgla, Candida glabrata; Ylip, Yarrowia lipolytica; Vpol, Vanderwaltozyma polyspora; Zpar, Zygosaccharomyces parabailii; Rmuc, Rhodotorula mucilaginosa; MT, metallothionein. Oliveira Jr. et al. Ascomycetes fungi (anamorphic and teleomorphic) usually cause soft-rot decay of wood with soft brown appearance and cracked and checked when dry (Nilsson et al., 1989; Blanchette, 1995). Oyster mushrooms, meadow mushrooms and button mushrooms all have different scientific classifications. Most infections reported list M. circinelloides and similar species such as M. indicus, M. ramosissimus, M. irregularis an… However, the results of Roller and Covill [28] demonstrated that the fungus Mucor racemosus, whose cell walls are composed of chitosan, was inhibited at a concentration of chitosan 1 g × L−1, on contrary to Allan and Hadwiger [11] proposition, which included strains of Mucor spp. For example, the PLA−CNC/graphene film at a ratio 50/50 exhibited an increase of 8% and 11% in the Young's modulus and tensile strength, respectively, compared with film, in which PLA was blended with the organic surfactant Triton X-100 [162]. Decaying fruits become “juicy” within which are abundant spores of the fungus (Li et al. However, for Rhizopus rot, the mycelia are interwoven with stolons with dark sporangiophores and black sporangia. ML bootstrap support values greater than 70% are shown near the nodes. Cuero et al. Reproduced from E.N. (2015). Aromatic amino acids (Phe, Tyr, and Trp) and His residues are also present in these fungal MTs. Deuteromycetes? Both amino acid blocks present a similar pattern which can be summarized as CXC(X)2–13CXC. 19. Saksenaea Fill in the blanks in regards to the common characteristics of Zygomycetes as a whole: Species confirmed with pathogenicity studies are marked with #. This does not correspond to the taxonomic division to which these yeast genera belong. On the other hand, as reported by Oliveira Jr. et al. The sporangium is non-apophysate with pigmented and ornamented zygosporangial walls. Some species are of biotechnological importance such as biofuel, enzyme, terpernoid production and biotransformation while other species cause mucoromycosis in immunosuppressed humans (Nguyen et al. Mucor species are commonly isolated from soil, dung, insect, and fruits (Benny 2008). Minimum inhibitory concentrations (MICs) of the chitosans with different DP (degree of polymerization) and different FA (fraction of acetylation) against Alternaria alternata, Botrytis cinerea, and Rhizopus stolonifer. 2016; Michailides and Spotts 1990). Ito et al. The zygospore typically results from the complete fusion of the two gametangia during gametangial copulation. 2014; Nguyen and Lee 2018). The use of five markers (ITS, rpb1, tsr1, mcm7 and cfs) phylogeny by Wagner et al. Mucor rot often develops by infecting punctured wounds and cracks on the surface of the fruit, stem end or calyx of the host. They commonly reside in soils, on plants and even in the digestive systems of various animals. By continuing you agree to the use of cookies. 2017). They are mostly saprophytic fungi which mostly grow on stable bread, jam As with most MTs, tryptophan residues are practically absent in fungal MT molecules, except in the zygomycete Mucor racemosus CuMT (CUP1), which has one Trp residue. The initial symptoms of Mucor rot are similar to plant diseases caused by green mold, blue mold, and sour mold. (A) Multiple alignment (T-Coffee program) from seven selected filamentous fungi MT sequences. The type species are in bold. The genus Mucor belongs to the zygomycotan order Mucorales. Asexual reproduction Asexual reproduction takes place by formation of asexual spores like sporangiospores, chlamydospore, oidia. Reserve food material of fungi is [BHU 1992, 94, 2000; KCET 1998; MP PMT 2000; CBSE PMT 2000; Orissa JEE 2004, 05] A) Starch done clear Voucher strains are also in bold. He isolated Aspergillus flavus, A. fumigatus, A. glaucus, A. niger, A. ochraceopetaliformis, and Emericella nidulans. Single-walled carbon nanotubes functionalized with herbal extract of Hempedu bumi displayed a zone of inhibition >1.0 cm against the pathogen A. niger [165]. About 2% of His residues forms the amino acid composition of both yeast and filamentous fungi MTs. Table 17.2 lists the MICs of chitosan samples against fungi A. alternata, B. cinerea, and R. stolonifer. Mucor species especially M. fragilis, M. irregularis, M. piriformis and M. racemosus often cause postharvest diseases such as Mucor rot and soft rot.
