Phosphorus (P) is an essential nutrient for plants and is acquired from the rhizosphere solution as inorganic phosphate. P is one of the least available mineral nutrients, particularly in highly weathered, tropical soils, and can substantially limit plant growth. The aim of this work was to study a possible effect of root morphology and the expression pattern of related candidate genes on P efficiency in maize. Our field phenotyping results under low and high P conditions enabled us to identify two contrasting genotypes for P acquisition efficiency that were used for the root traits studies. Root morphology was assessed in a paper pouch system to investigate root traits that could be involved in P acquisition efficiency. The genes, Rtcs, Bk2 and Rth3, which are known to be involved in root morphology, showed higher expression in the P efficient line relative to the P inefficient line. Overall, root traits showed high heritability and a low coefficient of variation. Principal component analysis revealed that out of the 24 root traits analysed, only four root traits were needed to adequately represent the diversity among genotypes. The information generated by this study will be useful for establishing early selection strategies for P efficiency in maize, which are needed to support subsequent molecular and physiological studies. |

Abstract: The objective of this work was to characterize banana and plantain genotypes and to identify the most promising for flour production. Sixteen plantain genotypes and four banana cultivars were evaluated for dry matter content and flour yield. The obtained flours were characterized by color (L*, C*, and h*) and by moisture, total and resistant starch, ash, protein, lipid, and fiber contents. A low genetic variability was observed among plantains for the evaluated physicochemical and nutritional characteristics. The Chifre de Vaca, Comprida, Terra Ponta Aparada, Trois Vert, Terrinha, and Terra Maranhão plantains showed the highest dry matter contents and flour yield. The Chifre de Vaca, Comprida, Curare Enano, Mongolo, Trois Vert, and Terra Maranhão plantains and the 'Pacovan', 'Prata Anã', 'BRS Platina', and 'BRS SCS Belluna' bananas had resistant starch levels above 60%. The flour from 'BRS SCS Belluna' presented the highest contents of ash, protein, and fiber, as well as the lowest caloric value. Considering dry matter content, flour yields, and resistant starch, the Chifre de Vaca, Comprida, Trois Vert, and Terra Maranhão plantains are the best options to produce flour. From a nutritional point of view, 'BRS SCS Belluna' is a good option for producing flour rich in resistant starch, mineral, protein, and fiber contents. Resumo: O objetivo deste trabalho foi caracterizar genótipos de bananas e plátanos e identificar os mais promissores para a fabricação de farinha. Dezesseis genótipos de plátanos e quatro cultivares de banana foram avaliados quanto ao teor de matéria seca e ao rendimento em farinha. As farinhas obtidas foram caracterizadas quanto à cor (L*, C* e h*) e aos teores de umidade, amido total e resistente, cinzas, proteínas, lipídeos e fibras. Observou-se baixa variabilidade genética entre os plátanos para as características físico-químicas e nutricionais avaliadas. Os plátanos Chifre de Vaca, Comprida, Terra Ponta Aparada, Trois Vert, Terrinha e Terra Maranhão apresentaram maiores teores de matéria seca e melhor rendimento em farinha. Os plátanos Chifre de Vaca, Comprida, Curare Enano, Mongolo, Trois Vert e Terra Maranhão e as bananas 'Pacovan', 'Prata Anã', 'BRS Platina' e 'BRS SCS Belluna' apresentaram teores de amido resistente acima de 60%. A farinha de 'BRS SCS Belluna' apresentou maiores teores de cinzas, proteína e fibras, bem como menor valor calórico. Ao se considerar matéria seca, rendimento em farinha e teor de amido resistente, os plátanos Chifre de Vaca, Comprida, Trois Vert e Terra Maranhão são as melhores opções para produzir farinha. Do ponto de vista nutricional, a banana 'BRS SCS Belluna' é uma boa opção para produção de farinha com altos teores de amido resistente, minerais, proteínas e fibras.
