Engineering doi: 10.1016/j.eng.2023.08.015

Abstract: Botrytis cinerea (B. cinerea) is a devastating phytopathogenic fungus that exploits light cues to optimizeHere, we identify a novel light-signaling component in B. cinerea, BcCfaS, which encodes a putative cyclopropanea number of previously unknown fungal lipids and many BcCfaS-regulated lipids are identified in B. cinerea

Frontiers of Agricultural Science and Engineering 2018, Volume 5, Issue 2,   Pages 262-270 doi: 10.15302/J-FASE-2017166

Abstract: Four kinds of antifungal compounds from an extract of A21 with molecular masses of 883.56, 897.59, 947.55, and 961.58 Da were characterized as the members of fusaricidin-type of antibiotics according to LC-MS analysis. Fusaricidins isolated from culture filtrate displayed high antagonistic activity against several plant fungal pathogens, especially , the causal agent of gray mold. The fusaricidins biosynthetic gene cluster (BGC) from A21 was cloned by PCR and comparative cluster analysis revealed that gene , the 3′ boundary of the fusaricidin BGC in strain PKB1, was not present in fusaricidin BGC of A21, indicating that is not necessary for fusaricidin synthesis. Fusaricidin extract from A21 significantly reduced gray mold disease incidence and severity on tomato. The mRNA levels for three patho-genesis-related proteins (PRs) revealed that treatment of tomato leaves with fusaricidin extract induced the expression of PR genes to different levels, suggesting that one reason for the reduction of gray mold infection by fusaricidin is induction of PR proteins, which lead to increased resistance to pathogens. This is the first report of the application of fusaricidins to control tomato gray mold and the comparative cluster analysis provides important molecular basis for research on fusaricidin biosynthesis.

Transformation of triclosan by a novel cold-adapted laccase from

Yuanyuan Shi, Deyang Kong, Jiayang Liu, Junhe Lu, Xiaoming Yin, Quansuo Zhou

Frontiers of Environmental Science & Engineering 2017, Volume 11, Issue 3, doi: 10.1007/s11783-017-0927-5

Abstract: This work investigated the transformation of triclosan (TCS) by laccase produced by a pathogen isolated from rotten tomato. The pathogen was characterized as sp. FQ, belonging to subphylum . The laccase exhibited cold-adaptation with relatively high activity at 20°C. The laccase could effectively transform TCS. Approximately 62% TCS could be removed at dose of 1.0 unit·mL in 120 min. The reaction rate appeared to be to the concentration of the substrate, suggesting the laccase activity remained stable during the reaction. Transformation products of TCS were analyzed by mass spectrometry and it was revealed that TCS dimers were formed via radical coupling pathways. During this process, laccase catalyzed oxidation of TCS to form a radical intermediate is the rate limiting step. However, this step can be reversed by humic acid. Overall, the laccase showed great potential in the treatment of phenolic contaminants. Since laccase is widely presented in natural environment, this study also revealed an important pathway involved in the transformation of phenolic contaminants in the environment.

Frontiers of Agricultural Science and Engineering 2021, Volume 8, Issue 4,   Pages 635-644 doi: 10.15302/J-FASE-2020343

Abstract: The antifungal effectiveness of extracts of five medicinal plant species was determined. The inhibitory activity of extracts of , , , and were evaluated against the mycelial growth of the plant pathogenic fungi , , and . All plant extracts were prepared at 60°C using solvents (either water, 50% ethanol ( ), 95% ethanol ( ), ethyl acetate or petroleum ether). Fungicidal effects of all plants tested were confirmed. Different extracts from the same plant species gave different degrees of inhibition. All aqueous extracts had weak or no activity on all fungi tested. Ethyl acetate and 95% ethanol extracts from rhizomes gave greater inhibition and a broader spectrum inhibition than the other extracts. may have potential as a new natural fungicide and may be used for the preservation of agricultural and forestry products such as fruits and vegetables.

Frontiers of Agricultural Science and Engineering 2018, Volume 5, Issue 2,   Pages 271-279 doi: 10.15302/J-FASE-2018214

Abstract: This study reports a strain of CCTCC-SBW0162 with potential to enhance biocontrol activity against gray mold pathogen, , and with a pivotal role in tomato ( ) plant growth enhancement. A total of 254 isolates were screened by antagonistic assay. Of these, 10 were selected for greenhouse experiments based on their greater inhibition of . The antagonistic assay and greenhouse experiments indicated that CCTCC-SBW0162 gave the highest inhibition rate (90.6%) and disease reduction (80.7%). Also, to study the possible mechanism associated with antifungal activity of CCTCC-SBW0162 against , molecular docking was used to assess the interactions between CCTCC-SBW0162-derived metabolites, and pathogencity and virulence related proteins of . The molecular docking results indicated that the combination of harzianopyridone, harzianolide and anthraquinone C derived from CCTCC-SBW0162 could synergistically improve antifungal activity against through the inhibition/modification of pathogenicity and virulence related proteins. However, this computerized modeling work emphasized the need for further study in the laboratory to confirm the effect derived metabolites against the proteins of and their interactions.
