Common bean (Phaseolus vulgaris L.) cultivars with slow seed coat darkening benefit the growers by extending the seed storage period without losses in commercial quality. Seed coat darkening in pinto and carioca seeded common bean is controlled by recessive genes, but it is not known whether these genes are different or not. The objectives of this study were (i) to verify if the gene that controls seed coat darkening in common bean cultivars from different market classes is the same, and (ii) to evaluate the efficiency of the simple sequence repeat (SSR) marker Pvsd-1158 and the single nucleotide polymorphism (SNP) marker PvbHLHp12804 linked to the Sd gene in identifying carioca and mulatinho seeded lines contrasting for seed coat darkening. Seventeen lines were used for genotypic and phenotypic evaluations in two trials, and F2:3 progenies obtained from crosses between one pinto bean line (Sd gene) and two carioca lines that have slow seed coat darkening were used in segregation tests. The result of the two markers was identical and shown 87.5% coincidence with phenotypic data. Only two lines, CNFM 11940 (mulatinho) and TAA Dama (carioca), exhibited slow seed coat darkening and marker alleles related to regular darkening. Therefore, there was recombination between the markers and the Sd gene, or there is another gene causing slow seed coat darkening in these lines. All F2:3 progenies exhibited slow seed coat darkening, indicating that there was no segregation. The two markers are efficient for assisted selection. Results of the genotypic evaluations and the segregation test indicating that the same gene (Sd) is responsible for seed coat darkening in pinto and carioca beans.

Acidic soils are distributed worldwide, predominantly in tropical and subtropical areas,reaching around 50% of the arable soil. This type of soil strongly reduces crop production, mainly because of the presence of aluminum, which has its solubility increased at low pH levels. A well-known physiological mechanism used by plants to cope with Al stress involves activation of membrane transporters responsible for organic acid anions secretion from the root apex to the rhizosphere, which chelate Al, preventing its absorption by roots. In sorghum, a membrane transporter gene belonging to multidrug and toxic compound extrusion (MATE) family was identified and characterized as an aluminum-activated citrate transporter gene responsible for Al tolerance in this crop. Setaria viridis is an emerging model for C4 species and it is an important model to validate some genes for further C4 crops transformation, such as sugarcane, maize, and wheat. In the present work, Setaria viridis was used as a model plant to overexpress a newly identified MATE gene from Brachypodium distachyon(BdMATE), closely related to SbMATE, for aluminum tolerance assays. Transgenic S. viridis plants overexpressing a BdMATE presented an improved Al tolerance phenotype, characterized by sustained root growth and exclusion of aluminum from the root apex in transgenic plants, as confirmed by hematoxylin assay. In addition, transgenic plants showed higher root citrate exudation into the rhizosphere, suggesting that Al tolerance improvement in these plants could be related to the chelation of the metal by the organic acid anion. These results suggest that BdMATE gene can be used to transform C4 crops of economic importance with improved aluminum tolerance.
