Int J Biol Macromol 2022; 217:282-290. [PMID: 35835303 DOI: 10.1016/j.ijbiomac.2022.07.034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Revised: 06/20/2022] [Accepted: 07/05/2022] [Indexed: 11/30/2022]
Abstract
Chemical agents are effective treatment methods for anthracnose induced by pathogenic Colletotrichum gloeosporioides on Stylosanthes. However, excess consumption of chemical agents destroys the environment, synthetic biology was capable of conquering the issue. The antifungal agent is developed by enclosing a bio-synthesized peptide aptamer with layered montmorillonite via electrostatic interaction. Compared with free peptide aptamer, the nanocomposite exhibits higher antifungal activity against Colletotrichum gloeosporioides, further improving the utilization of peptide aptamer. The nanocomposite killed Colletotrichum gloeosporioides by releasing peptide aptamer after they entered the spore. Moreover, montmorillonite enhances the adhesion ability of peptide aptamer via hydrophobic interactions between nanomaterials and leaves, prolonging the extension time of nanocomposite on leaves. Consequently, 0.1 mg of nanocomposite demonstrates a comparable effect to commercial carbendazim (1 %) to prevent anthracnose on leaves of Stylosanthes induced by HK-04 at room temperature. This work demonstrates an alternative to commercial antifungal agents and proposes a versatile approach to preparing environmental-friendly antifungal agents to inhibit fungal infections on crops.

Abstract
Colletotrichum horii is a main causal agent of persimmon (Diospyros kaki) anthracnose and is distributed widely in persimmon-producing areas of the world. Here, we report the first high-quality draft genome sequence of C. horii strain SD010. This will provide a reference for understanding adaptive evolution of genome structure, genes, and population diversity among members of the C. gloeosporioides species complex, and also help in understanding the mechanisms of host-pathogen interactions and improve management strategies of anthracnose.

Identification and Comparison of Colletotrichum Secreted Effector Candidates Reveal Two Independent Lineages Pathogenic to Soybean. Pathogens 2021; 10:pathogens10111520. [PMID: 34832675 PMCID: PMC8625359 DOI: 10.3390/pathogens10111520] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2021] [Revised: 11/16/2021] [Accepted: 11/18/2021] [Indexed: 11/16/2022] Open
Abstract
Colletotrichum is one of the most important plant pathogenic genus of fungi due to its scientific and economic impact. A wide range of hosts can be infected by Colletotrichum spp., which causes losses in crops of major importance worldwide, such as soybean. Soybean anthracnose is mainly caused by C. truncatum, but other species have been identified at an increasing rate during the last decade, becoming one of the most important limiting factors to soybean production in several regions. To gain a better understanding of the evolutionary origin of soybean anthracnose, we compared the repertoire of effector candidates of four Colletotrichum species pathogenic to soybean and eight species not pathogenic. Our results show that the four species infecting soybean belong to two lineages and do not share any effector candidates. These results strongly suggest that two Colletotrichum lineages have acquired the capability to infect soybean independently. This study also provides, for each lineage, a set of candidate effectors encoding genes that may have important roles in pathogenicity towards soybean offering a new resource useful for further research on soybean anthracnose management.

Abstract
AbstractThis is a continuation of a series focused on providing a stable platform for the taxonomy of phytopathogenic fungi and fungus-like organisms. This paper focuses on one family: Erysiphaceae and 24 phytopathogenic genera: Armillaria, Barriopsis, Cercospora, Cladosporium, Clinoconidium, Colletotrichum, Cylindrocladiella, Dothidotthia,, Fomitopsis, Ganoderma, Golovinomyces, Heterobasidium, Meliola, Mucor, Neoerysiphe, Nothophoma, Phellinus, Phytophthora, Pseudoseptoria, Pythium, Rhizopus, Stemphylium, Thyrostroma and Wojnowiciella. Each genus is provided with a taxonomic background, distribution, hosts, disease symptoms, and updated backbone trees. Species confirmed with pathogenicity studies are denoted when data are available. Six of the genera are updated from previous entries as many new species have been described.
