Abstract: The rhizosphere microbiome plays a key role in plant protection against soil-borne pathogens. Plant breeding for resistance against soil-borne pathogens can alter the rhizosphere microbiome. However, most studies have focused on bacterial and fungal communities, leaving the role of the virus and viroids unassessed. Here, we tested the influence of resistance breeding on the composition of rhizosphere viruses and viroids. By analyzing metatranscriptomes from the rhizosphere of common bean (Phaseolus vulgaris) cultivars with varying resistance to the soil-borne pathogen Fusarium oxysporum, we recovered sequences representing 78 and 23 novel populations of viruses and viroids, respectively. We compared the abundances of these infectious agents across the different cultivars and found that the Fusarium-resistant cultivar harbored >1.2 times more viroids and a more different composition of viroids and viruses than less resistant plants. Given their role in interfering with host metabolism and their potential influence on plant-fungi associations, our study suggests that changes in the rhizosphere infectome are an important consideration in breeding for resistance against soil-borne pathogens. |

Biomass sorghum [Sorghum bicolor (L.) Moench] has unique characteristics that allow its use as a feedstock for bioenergy production. This study aimed to analyse the growth and accumulation of biomass and lignocellulosic compounds in photoperiod-sensitive biomass sorghum genotypes and to evaluate interactions with the environment at different phenological stages using the absolute and relative crop growth rates. Four photoperiodsensitive biomass sorghum genotypes were evaluated over two crop years and two sites in the state of Minas Gerais, Brazil. It was mensured agronomic and technological traits. The mean performance of the genotypes were adjusted using logistic and polynomial regression models, and the absolute (CGR) and relative (RCGR) growth rates were subsequently estimated. The environment (site and/or crop year) influenced the trait expression regarding plant height, cellulose and lignin accumulation. The genotypes at Sete Lagoas site matured earlier, with a greater plant height and greater accumulation of biomass and lignocellulosic compounds, except lignin, over a shorter period compared to Lavras site. Across genotypes and environments, CGRs with a peak inflection at approximately 90 days after sowing (DAS) were observed for growth and biomass production, but a decrease starting at 30 DAS was observed in the CGRs for lignocellulosic compounds and in the RCGRs for growth, biomass production and lignocellulosic compounds. In addition, at both sites, the crop could be harvested earlier, at approximately 120 DAS in Sete Lagoas and 150 DAS in Lavras, given the high biomass production, dry matter percentage above 30% and high content of lignocellulosic compounds.
