“…183) and furanone derivatives 443–445 (ref. 184) were also obtained from various species of Aspergillus . Other Aspergillus strains were the sources of diphenolic compound 446 (as a racemate), 185 macrolide 447 , 186 quinoline alkaloid 448 , sesquiterpenoids 449–451 (the last a known synthetic compound) 187 and meroterpenoids 452–454 , austineol A and precalidodehydroaustin (the last two for which the absolute configurations were determined as 455 and 456 respectively).…”

Aims:The control of Xanthomonas citri subsp. citri (X. citri), causal agent of citrus canker, relies heavily on integrated agricultural practices involving the use of copper-based chemicals. Considering the need for alternatives to control this disease and the potential of fungi from extreme environments as producers of bioactive metabolites, we isolated and identified a bioactive compound from Penicillium sp. CRM 1540 isolated from Antarctica marine sediment. Methods and Results:The potential of compound as an antibacterial agent against X. citri was assessed through in vitro and greenhouse experiments. Molecular taxonomy indicates that this fungus is a possible new species of Penicillium. Results revealed 90% bacterial inhibition in vitro at 25 µg ml -1 and a decrease in 75.37% of citrus canker symptoms emergency in vivo in treated leaves of Citrus sinensis (L.)Osbeck considering the number of lesions per cm 2 (p < 0.05) in comparison with the control. The structure of the active agent was identified as penicillic acid based on a detailed spectroscopic analysis. Conclusion:Penicillic acid can be an alternative against citrus canker.

“…Thus far, scientists have isolated numerous natural products with antitumor, antibacterial, and other biological activities from marine organisms [ 12 , 15 , 16 , 17 , 18 , 19 ]. Modern pharmacological studies also demonstrate that many marine biological metabolites show good effects on killing phytopathogenic bacteria, which possibly can be used for developing biological fungicides [ 20 , 21 , 22 , 23 , 24 ]. In fact, at the present, marine organisms have become an important resource for developing new biological fungicides to control plant diseases.…”

Plant diseases have been threatening food production. Controlling plant pathogens has become an important strategy to ensure food security. Although chemical control is an effective disease control strategy, its application is limited by many problems, such as environmental impact and pathogen resistance. In order to overcome these problems, it is necessary to develop more chemical reagents with new functional mechanisms. Due to their special living environment, marine organisms have produced a variety of bioactive compounds with novel structures, which have the potential to develop new fungicides. In the past two decades, screening marine bioactive compounds to inhibit plant pathogens has been a hot topic. In this review, we summarize the screening methods of marine active substances from plant pathogens, the identification of marine active substances from different sources, and the structure and antibacterial mechanism of marine active natural products. Finally, the application prospect of marine bioactive substances in plant disease control was prospected.
