TL;DR: It is concluded that bean plants at P-deficient conditions increase the activities of phosphatases and phytases in nodules, which may constitute an adaptive mechanism for N2-fixing legumes to tolerate P deficiency, by increasing the utilisation of the scarce P within the nodules.

TL;DR: The establishment of a profuse root system during pod setting, associated with the continuous N and P acquisition during early pod filling, seems to be relevant for higher grain yields of common bean.

TL;DR: O metodo da intersecao subestimou os valores de area e comprimento nas raizes finas e o metodo fotoeletrico quantifica a area com um medidor eletronico foram comparados na determinacao do compriment, area superficial e raio medio radicular.

TL;DR: The results indicate that wild bean genotypes are not more tolerant to low P soils, but the genotypic variation observed suggests these materials as a source of genetic diversity for nutritional breeding programs.

TL;DR: 'Negro Argel' presented lower reductions in stem biomass at the end of growth cycle, in leaf area duration, and in grain yield, demonstrating a higher drought tolerance, whereas Carioca was the cultivar most sensitive to water stress.
