The plant Chloranthus japonicus Sieb is known for its anticancer properties and mainly distributed in China, Japan, and Korea. In this study, we firstly investigated the diversity and antimicrobial activity of the culturable endophytic fungi from C. japonicus. A total of 332 fungal colonies were successfully isolated from 555 tissue segments of the medicinal plant C. japonicus collected from Qinling Mountains, China. One hundred and thirty representative morphotype strains were identified according to ITS rDNA sequence analyses and were grouped into three phyla (Ascomycota, Basidiomycota, Mucoromycota), five classes (Dothideomycetes, Sordariomycetes, Eurotiomycetes, Agaricomycetes, Mucoromycetes), and at least 30 genera. Colletotrichum (RA, 60.54%) was the most abundant genus, followed by Aspergillus (RA, 11.75%) and Diaporthe (RA, 9.34%). The Species Richness Index (S, 56) and the Shannon-Wiener Index (H′, 2.7076) indicated that C. japonicus harbored abundant fungal resources. Thirteen out of 130 endophytic fungal ethyl acetate extracts exhibited inhibitory activities against at least one pathogenic bacterium or fungus. Among of these, F8158, which was identified as Trichoderma cf. harzianum, exhibited good antagonistic capacities (the percent inhibition of mycelial growth ranged from 47.72~88.18) for different pathogens and has a potential application in biological control. In addition, it is noteworthy that the strain F8157 (Thanatephorus cucumeris, an opportunistic pathogen) showed antibacterial and antifungal activity, which is reported firstly in this study, and should be investigated further. Taken together, these results indicated that the endophytic fungi from C. japonicus may be of potential interest in screening bio-control agents and discovering of new bioactive compounds.

“…Many enzymes, such as catalase, polyphenoloxidase, and peroxidase, among others, demonstrate the capacity to decompose reactive oxygen species (Mittler, 2002). Changes in this enzymatic system of antioxidants are one of the first plant responses to pathogenic invasion, as revealed by Silva et al (2017) when evaluating the resistance induced by Trichoderma on manioc plants subjected to Table 1. Comparison between the group means of orthogonal constants and the anthracnose disease severity and enzymatic activities in leaves of the cowpea cultivar "sempre-verde" (Vigna unguiculata (L.) Walp.)…”

J. M. Silva, M. B. C. L. Medeiros, J. T. C. Oliveira, E. V. Medeiros, C. M. Souza-Motta, and K. A. Moreira. 2018. Resistance inducers and biochemical mechanisms in the control anthracnosis on cowpea. Cien. Inv. Agr. 45(3): 290-300. Different responses are observed in plants after infection by pathogens. The usage of systemic inducers, whether biotic or abiotic,has the function to increase the enzymatic production of the plant defense system. In that sense, our present research aims to evaluate the disease severity of anthracnose in the cowpea cultivar "sempre-verde" infected with Colletotrichum lindemuthianum URM 5771 and subjected to both biotic and abiotic resistance inducers, as well as evaluate the enzymatic activity of plant defense. The experiment was performed in a greenhouse with a completely randomized splitplot design with six treatments: four abiotic plant resistance inducers, acibenzolar-S-methyl, β-aminobutyric acid, chitosan, and salicylic acid; one biotic inducer, the filamentous fungi Trichoderma aureoviride URM 5158; and a control with only water. The plant leaves were sampled at four time points, 4, 8, 12 and 20 days after inoculation with the plant pathogen, to measure the enzymatic activity of β-1,3-glucanase, catalase, peroxidase, polyphenoloxidase, and protease. The abiotic inducers acibenzolar-S-methyl, β-aminobutyric acid, and chitosan and the biotic inducer presented the highest potential in reducing the anthracnose caused by C. lindemuthianum URM 5771 in cowpea plants by showing the lowest values of injury severity over time. The disease progression showed a proportionate shift in enzymatic activity in that the inducers salicylic acid and T. aureoviride URM 5158 promoted the highest enzymatic activity when compared to the other inducers. High correlations between the enzymatic activity of peroxidase and polyphenoloxidase and anthracnose severity were observed in cowpea plants. The use of abiotic and biotic resistance inducers presents high potential for anthracnose control in cowpea plants; however, more studies should be carried out covering different environments, plant cultivars and climatic conditions.

“…contributes to biological control because of the ability to compete for nutrients and space (Harman, Herrera‐Estrella, Horwitz, & Lorito, ). Da Silva, de Medeiros, da Silva et al () indicated that Trichoderma aureoviride Rifai URM 5158 and T. hamatum (Bonord.) Bainier URM 6656 were efficient antagonists against cassava black root rot through different mechanisms.…”

The objective of the present study was to evaluate the natural suppressive capacity of soils from forest, and monocropping and intercropping systems, against root rot, caused by Scytalidium lignicola, in a greenhouse experiment. We used soils from a tropical dry forest (FOR) and two intercropping and two monoculture systems. The first intercrop was maize and beans (CORNCOWP), and the second intercrop was cassava, pigeon peas and beans (CASPIGPCOWP). The first monoculture was beans, and the second was passion fruit. The intercropping soils showed a higher capacity to suppress black root rot in cassava than the monoculture because such soils were able to reduce disease severity by about 50%. Bean soil in the monoculture showed less microbial biomass carbon than in the intercrop, with means of 10.05 and 38.2 mg/kg, respectively. The higher density of bacteria and fungal populations, microbial biomass, urease and arylsulphatase activities correlated with a decrease in disease severity. Soils from the intercrops produced changes in soil quality, primarily in the population and density of microorganisms, enzymatic activities, total organic carbon and nutrients, reducing disease severity in cassava plants. These effects were validated by multivariate principal component analysis and showed three distinct groups: one FOR, one intercropping and one monocropping. The majority of vectors were in the direction of FOR and intercropping soils. We have provided some of the first data related to the beneficial effects of intercropping on the suppression of black root rot in cassava, which is validated through different attributes.
