It is clear that cassava wild relatives are a reservoir of useful genes to be transferred to the cultivated species Manihot esculenta. However, the number of traits already identified is low when compared with the existent diversity. In this work, cassava wild relatives accessions of the Manihot anomala, M. caerulescens, M. dichotoma, M. flabellifolia, M. glaziovii, M. jacobinensis, M. peruviana and M. tomentosa were evaluated for disease incidence and severity in different regions of Brazil. Seedlings planted in Sao Miguel das Matas (SSM), Tancredo Neves (TN) and Cruz das Almas (CA), in the Bahia State and in Petrolina (PT) in the Pernambuco State were evaluated monthly from 6 to 12 month after planting. All the diseases observed are common to the cultivated cassava. In Bahia the incidence of anthracnose, rust, brown leaf spot (BLS), white leaf spot and diffuse leaf spot was observed. In PT, the disease incidence was limited to sporadic lesions of BLS. BLS was the most frequent and severe disease, with the highest values registered in SMM. TN and CA. Regardless of the region, accessions of M. glaziovii were most susceptible and M. flabellifolia most resistant to BLS. Accessions with high levels of resistance for all the diseases evaluated were identified, except in M. glaziovii where all the accessions were highly susceptible to BLS and anthracnose. As far as we know this is the first survey of disease incidence and severity in cassava wild species in Brazil. |

Abstract: Bacillus spp. are widely marketed and used in agricultural systems as antagonists to various phytopathogens, but it can also benefit the plant as plant growth promoters. Therefore, the longer presence of the bacterium in the rhizosphere would result in a prolonged growth-promoting benefit, but little is yet known about its persistence in the rhizosphere after seed coating. The objectives of this study were to evaluate the tomato growth promotion mediated by Bacillus licheniformis FMCH001 and Bacillus subtilis FMCH002 and the survival rate of these bacteria both in shoots and in the rhizosphere. The Bacillus strains used throughout this study were obtained from Quartzo® produced by Chr. Hansen. The application of a mixture of B. subtilis and B. licheniformis (Quartzo®) at concentrations 1 × 108, 1 × 109, and 1 × 1010 CFU mL-1, as well as the application of B. subtilis and B. licheniformis individually at concentration 1 × 108 CFU mL-1, increased fresh and dry masses of shoot and root system, volume of root system, and length of roots of tomato plants when compared to control. Both Bacillus strains produced IAA after 48 h of in vitro. Bacillus colonies obtained from plant sap were morphologically similar to colonies of B. subtilis and B. licheniformis strains and were detected in inoculated on plants and not detected in control ones. A similar pattern was obtained through DNA-based detection (qPCR). Therefore, B. subtilis and B. licheniformis were able to produce auxin, promote tomato growth, and colonize and persist in the rhizosphere.
