Journal Article 2002

Aluminum stress stimulates the accumulation of organic acids in root apices of Brachiaria species

Autor: Wenzl, Peter Chavez, Alba L. Patiño, Gloria M. Mayer, Jorge Edgard Rao, Idupulapati M.

Aluminum‐resistant Brachiaria decumbens Stapf cv. Basilisk (signalgrass) and closely related, but less resistant Brachiaria ruziziensis Germain & Evrard cv. Common (ruzigrass) both accumulated high concentrations of aluminum (Al) in roots. Approximately two thirds of the total Al was complexed by...

Root adaptations to soils with low fertility and aluminium toxicity

Autor: Rao, Idupulapati M. Miles, John W. Beebe, Stephen E. Horst, Walter J.

BACKGROUND Plants depend on their root systems to acquire the water and nutrients necessary for their survival in nature, and for their yield and nutritional quality in agriculture. Root systems are complex and a variety of root phenes have been identified as contributors to adaptation to soils w...

Root traits and their potential links to plant ideotypes to improve drought resistance in common bean

Autor: Polanía Perdomo, José A. Poschenrieder, Charlotte Rao, Idupulapati M. Beebe, Stephen E.

Drought stress limits growth and yield of crops, particularly under smallholder production systems with minimal use of inputs and edaphic limitations such as nitrogen (N) deficiency. The development of genotypes adapted to these conditions through genetic improvement is an important strategy to a...

Biological nitrification inhibition (BNI): is it a widespread phenomenon?

Autor: Subbaraoa, Guntur V. Rondón, Marco Antonio Ito, O. Ishikawa, T. Rao, Idupulapati M. Nakahara, K. Lascano, Carlos E. Berry, W.L.

Regulating nitrification could be a key strategy in improving nitrogen (N) recovery and agronomic N-use efficiency in situations where the loss of N following nitrification is significant. A highly sensitive bioassay using recombinant luminescent Nitrosomonas europaea, has been developed that can...

Intracellular distribution and binding state of aluminum in root apices of two common bean (Phaseolus vulgaris) genotypes in relation to Al toxicity

Autor: Rangel Becerra, AF Rao, Idupulapati M. Horst, Walter J.

The role of the intracellular distribution and binding state of aluminum (Al) in Al toxicity, using Al exchange and Al fractionation methodologies, were studied in two common bean (Phaseolus vulgaris L.) genotypes differing in Al resistance. These two genotypes are characterized by a similar init...

A comparative study on plant growth and root plasticity responses of two Brachiaria forage grasses grown in nutrient solution at low and high phosphorus supply

Autor: Louw-Gaume, A Rao, Idupulapati M. Gaume, A Frossard, Emmanuel

Brachiaria forage grasses are widely used for livestock production in the tropics. Signalgrass (Brachiaria decumbens cv. Basilisk, CIAT 606) is better adapted to low phosphorus (P) soils than ruzigrass (B. ruziziensis cv. Kennedy, CIAT 654), but the physiological basis of differences in low-P ada...

Alteration of cell-wall porosity is involved in osmotic stress-induced enhancement of aluminium resistance in common bean (Phaseolus vulgaris L.)

Autor: Yang, Z Eticha, D Rao, Idupulapati M. Horst, Walter J.

Aluminium (Al) toxicity and drought are the two major abiotic stress factors limiting common bean production in the tropics. Using hydroponics, the short-term effects of combined Al toxicity and drought stress on root growth and Al uptake into the root apex were investigated. In the presence of A...
