Nitrogen (N) is the most important soil nutrient for common beans; the main sources are mineral N fertilizers and symbiotic N fixation (SNF). The common bean (Phaseolus vulgaris) is a N fixing species... ... |
 Author(s): GOUVEIA, J. J. de S.; SILVA, M. V. G. B.; PAIVA, S. R.; OLIVEIRA, S. M. P. de The identification of regions that have undergone selection is one of the principal goals of theoretical and applied evolutionary genetics. Such studies can also provide information about the evolutio... ... |
