Rhizobacteria are valuable sources of compounds that can be used for the integrated management of diseases in rice. Here, we aimed to explore the metabolism and organize and annotate the metabolites of Bacillus sp. and Serratia marcescens isolates using molecular networking and evaluate their fungicidal effects against Magnaporthe oryzae and Bipolaris oryzae. We obtained bacterial extracts after 6 and 16-h incubation via liquid?liquid extraction using ethyl acetate as solvent. We performed UHPLC-MS analysis and data processing using molecular networking and conducted biological assays in rice plants. Using the Global Natural Product Social spectral libraries, we annotated the following compounds: austinoneol, Phe-Pro, N-acetyl-l-leucine, Leu-Gly, Ile-Leu, Phe-Pro, 2,5-piperazinedione, 3-(1H-indol-3-methyl)-6-methyl-cyclo(d-Trp-l-Pro), and cholic acid. Results of the biological assays showed that the bacterial extracts reduced the mycelial growth of both pathogens in all treatments compared to the control. In the greenhouse setup, 8 days after the challenge for leaf gray spot and leaf blast, all treatments affected up to 4.4% of the leaf area, with an area under disease progress curve of 13.24, showing significant difference compared to the control, which affected 23% of the leaf area, with an AUDPC of 44.65. Our study provides potential new sources of natural products to be applied in the integrated management of rice. |

Zephyranthes sylvatica is a beautiful lily, endemic from the Brazilian Caatinga. Although it has a great ornamental potential, little is known about this species, especially regarding its seeds germination process. Aiming to characterize the germination of Z. sylvatica seeds, we studied its imbibition curve, optimum temperature and substrate for germination and seedling emergence, osmotic and salt stress tolerance, as well as the tolerance to frosting/ defrosting, which indicates long term cryostorage potential. The germination of Z. sylvatica presents a triphasic model of imbibition, in which the primary root protrusion occurs after 72 hours of imbibition. The ideal conditions for evaluating seed germination of Z. sylvatica is 25 °C, in paper rolls. These seeds are highly tolerant to osmotic stress, but not to salt stress. Z. sylvatica seeds can be cryopreservated without loss of germination and seed vigor. |
