“…In order to explore possible correlations between pathogen resistance in plants and the rhizosphere microbiome composition, we selected the most resistant (IAC Milenio) and most susceptible (IAC Alvorada) bean cultivars for detailed analysis. The resistant cultivar IAC Milenio used in our experiments is derived from a cross between two cultivars, one being a sibling line of the susceptible cultivar IAC Alvorada (Carbonell et al, 2014). Although they are genetically related, we hypothesized that even small changes in the genome of the Fox-resistant cultivar may affect rhizosphere community assembly.…”

The rhizosphere microbiome has a key role in plant growth and health, providing a first line of defense against root infections by soil-borne pathogens. Here, we investigated the composition and metabolic potential of the rhizobacterial community of different common bean (Phaseolus vulgaris) cultivars with variable levels of resistance to the fungal root pathogen Fusarium oxysporum (Fox). For the different bean cultivars grown in two soils with contrasting physicochemical properties and microbial diversity, rhizobacterial abundance was positively correlated with Fox resistance. Pseudomonadaceae, bacillaceae, solibacteraceae and cytophagaceae were more abundant in the rhizosphere of the Fox-resistant cultivar. Network analyses showed a modular topology of the rhizosphere microbiome of the Fox-resistant cultivar, suggesting a more complex and highly connected bacterial community than in the rhizosphere of the Fox-susceptible cultivar. Metagenome analyses further revealed that specific functional traits such as protein secretion systems and biosynthesis genes of antifungal phenazines and rhamnolipids were more abundant in the rhizobacterial community of the Fox-resistant cultivar. Our findings suggest that breeding for Fox resistance in common bean may have co-selected for other unknown plant traits that support a higher abundance of specific beneficial bacterial families in the rhizosphere with functional traits that reinforce the first line of defense.

“…The common bean (Phaseolus vulgaris L.) is a very important culture for Brazilians nutrition since it is an important source of proteins, carbohydrates and naturally rich in mineral nutrients (Carbonell et al, 2014). The average productivity and consumption are 1.6 t ha -1 and 16 kg person -1 year -1 respectively, and its cultivation occurs in all regions of the country, in different times of the year, using different planting systems, being especially cultivated by family farming (Companhia Nacional de Abastecimento -CONAB, 2019).…”

“…Lately, the culture has become more visible among the great grain farmers of the country that make use of advanced technology such as phytosanitary control, mechanical harvest and irrigation. However, the production is still unstable due to various factors, including environmental stresses (Carbonell et al, 2014;Gonçalves et al, 2019). The characterization of different varieties becomes important to identify materials less susceptible to stressful conditions, which is critical to food security.…”

Waterlogging effects upon the phenological phases of common bean cultivar BRSMG-Uai

et al. 2020

Common bean (Phaseolus vulgaris L.) is an important source of protein and carbohydrates, besides being rich in several mineral nutrients. In a flooding situation, the low availability of oxygen may result in hypoxia or anoxia condition. Therefore, this study aimed to evaluate the responses of the common bean cultivar BRSMG-Uai subjected to hypoxia in different phenological phases, analyzing its responses in terms of growth, productivity, carbon and nitrogen metabolism. Thus, seeds of common beans were germinated and when the seedling reached growth stage V1, they were transferred to plastic boxes containing 40L of nutritive solution with steady aeration. Distinct series of plants were exposed to air-restriction on their roots for nine days, in three different phenological phases V3/V4, R6 and R7. Samples were collected for biochemical and growth analyses in a completely random design (n=6). The plants subjected to low availability of oxygen presented a reduction in bean number, displaying the greatest loss in productivity in V3/V4, conferring the highest sensitivity to hypoxia in this phase. On the other hand, there was an increase in sugar concentration in leaves, and it was also possible to observe an increase in hydrogen peroxide in leaves and roots, concomitant with a decrease in superoxide dismutase activity in all phenological phases. There was also an increase in ascorbate peroxidase activity in roots in R6, as well as in nitrate reductase activity. We conclude that the cultivar BRSMG-Uai presents sensitivity to low oxygen availability, and the phenological phaseV3/V4 is the most critical for it.

“…Recommendation of new cultivars in Brazil is mainly based on their agronomic traits, such as pest and disease resistance and yield (Carbonell et al 2014, Lima et al 2014, Melo et al 2014, Ramalho et al 2016. Nevertheless, species for human consumption, like dry bean, must receive the approval of producers and also of consumers.…”
