Quantitative trait loci for root morphology traits under aluminum stress in common bean (Phaseolus vulgaris L.)

Autor: López Marin, H.D. Rao, Idupulapati M. Blair, Matthew W.

Aluminum (Al) toxicity is a major limiting factor of crop production in acid soils, which are found mostly in developing countries of the tropics and sub-tropics. Common bean (Phaseolus vulgaris L.) is particularly sensitive to Al toxicity; and development of genotypes with better root growth in ...

Phenotypic evaluation of interspecific recombinant inbred lines (RILs) of Phaseolus species for aluminium resistance and shoot and root growth response to aluminium–toxic acid soil

Autor: Butare, Louis Rao, Idupulapati M. Lepoivre, Philippe Cajiao V., César Hernando Polanía Perdomo, José A. Cuasquer, Juan B. Beebe, Stephen E.

Aluminium (Al) toxicity limits common bean productivity in acid soil regions of the tropics. To improve Al resistance of common bean, Al-sensitive Phaseolus vulgaris (SER16) was crossed to Al-resistant P. coccineus (G35346-3Q) to create 94 F5:6 recombinant inbred lines (RILs) of the pedigree SER1...

Role of phosphoenolpyruvate carboxylase in the adaptation of a tropical forage grass to low-phosphorus acid soils

Autor: Begum, Hasna Hena Osaki, Mitsuru Nanamori, Masahito Watanabe, Toshihiro Shinano, Takuro Rao, Idupulapati M.

As Brachiaria hybrid cv. ‘Mulato’ has adapted to acid soils with extremely low phosphorus (P) contents, its low-P-tolerance mechanisms were investigated and compared with those of wheat (Triticum aestivum L.) and rice (Oryza sativa L. cv. ‘Kitaake’). Among the three plant species, the highest P-u...

Internal mechanisms of plant adaptation to aluminum toxicity and phosphorus starvation in three tropical forages

Autor: Watanabe, Toshihiro Osaki, Mitsuru Yano, Hiromi Rao, Idupulapati M.

Many tropical forage grasses and legumes grow well in acid soils, adapting to excess aluminum (Al) and phosphorus (P) starvation stresses by using mechanisms that are still unclear. To determine these mechanisms, responses to Al toxicity and P starvation in three tropical forages were studied: tw...

Aluminum stress inhibits accumulation of phosphorus in root apices of aluminum-sensitive but not aluminum-resistant brachiaria cultivar

Autor: Wenzl, Peter Mayer, Jorge Edgard Rao, Idupulapati M.

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...

Spatial aluminium sensitivity of root apices of two common bean (Phaseolus vulgaris L.) genotypes with contrasting aluminium resistance

The initial response of plants to aluminium (Al) is an inhibition of root elongation. In the present study, short and medium-term effects of Al treatment (20??M) on root growth and Al accumulation of two common bean (Phaseolus vulgaris L.) genotypes, VAX-1 (Al-sensitive) and Quimbaya (Al-resistan...

Simulating infertile acid soils with nutrient solutions: The effects on Brachiaria species

Autor: Wenzl, Peter Mancilla, LI Mayer, Jorge Edgard Albert, R. Rao, Idupulapati M.

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...
