Macrophomina phaseolina is a soil-borne phytopathogenic fungus that causes charcoal rot in several plant species, including sorghum. We constructed a draft genome of M. phaseolina isolate BRIP 70780a from sorghum, using long-read native DNA from MinION sequencing, which was error-corrected using short-read Illumina MiSeq reads. The draft genome, consisting of 22 contigs with an N50 of 4,257,441 bp, 99.3% complete benchmarking universal single-copy orthologs, and 14,471 genes, is a valuable resource to aid future studies in population genomics and molecular diagnostic marker development for rapid detection of the pathogen.

In the last decades, intensive crop management has involved excessive use of pesticides or fertilizers, compromising environmental integrity and public health. Accordingly, there has been worldwide pressure to find an eco-friendly and safe strategy to ensure agricultural productivity. Recently, Plant Growth-Promoting (PGP) rhizobacteria are receiving increasing attention as suitable biocontrol agents against agricultural pests. In the present study, 22 spore-forming bacteria were selected among a salt-pan rhizobacteria collection for their PGP traits and their antagonistic activity against the plant pathogen fungus Macrophomina phaseolina. Based on the higher antifungal activity, strain RHFS10, identified as Bacillus vallismortis, was furtherly examined and cell-free supernatants assays, column purification, and tandem mass spectrometry employed to purify and preliminarily identify the antifungal metabolites. Interestingly, the minimum inhibitory concentration assessed for the fractions active against M. phaseolina, resulted 10 times lower and more stable than the one estimated for the commercial fungicide pentachloronitrobenzene. These results suggest the use of B. vallismortis strain RHFS10 as a potential Plant Growth Promoting Rhizobacteria to efficiently control phytopathogenic fungus M. phaseolina, in alternative to chemical pesticides.

ABSTRACT Leaves, stems, roots and inflorescence of the asteraceous weed Circium arvense were extracted in methanol for two weeks. Methanol was evaporated in a rotary evaporator. Different concentrations (1, 2, 3, 4 and 5%) of methanolic extracts were prepared, and their antifungal activities were studied against Macrophomina phaseolina, using malt extract broth as growth medium. In general, extracts of all plant parts showed antifungal activities to variable extents. The highest antifungal activity occurred due to methanolic extract of leaves, followed by stem and root extracts, resulting in 10-74%, 6-57% and 11-39% reduction in fungal biomass over control, respectively. Inflorescence extract showed the least antifungal activity, resulting in 2-30% reduction in fungal biomass over control. There was a linear and inverse relationship between extract concentrations and fungal biomass for extracts of all the four parts. GC-MS analysis showed that there were 10 compounds in most effective methanolic leaf extract. Among these, 10-octadecanoic acid, methyl ester (26.442%), 2H-1-benzopyran, 6,7-dimethoxy-2-2-dimethyl (20.195%), hexadecanoic acid, methyl ester (15.752%) and 9,12-octadecadienoic acid (Z,Z)-, methyl ester (12.628%) were predominant compounds in the extract that may be responsible for antifungal activity. This study concludes that methanolic leaf extracts of C. arvense can be used for the management of M. phaseolina.
