The phosphorus (P) content of whole roots and root apices has been reported to increase under aluminum (Al) stress, particularly in Al-sensitive plant varieties. We investigated the impact of Al toxicity on the P content of root apices of two tropical forage cultivars of the Brachiaria genus, gro...
We summarize progress made towards the development of tools and knowledge that aid the genetic improvement of aluminum (Al) resistance in two of CIAT’s (International Center for Tropical Agriculture) commodity crops; common bean (Phaseolus vulgaris L.) and brachiariagrasses (Brachiaria spp. Grisi...
Understanding the distribution of genetic diversity within and among individuals, populations, species and gene pools is crucial for the efficient management of germplasm collections. Molecular markers are playing an increasing role in germplasm characterization, yet their broad application is li...
Aluminum toxicity limits plant growth in acid soils. Because of their advanced state of weathering, acid soils of the tropics also tend to be deficient in nutrients. A realistic assessment of plant adaptation to these soils would therefore require Al-toxic conditions under which growth is simulta...
