Genetic diversity for aluminum tolerance in sorghum

Theoretical and Applied Genetics, 2007
Genetic variation for aluminum (Al) tolerance in plants has allowed the development of cultivars that are high yielding on acidic, Al toxic soils. However, knowledge of intraspecific variation for Al tolerance control is needed in order to assess the potential for further Al tolerance improvement. Here we focused on the major sorghum Al tolerance gene,

A NAC transcription factor represses a module associated with xyloglucan content and regulates aluminum tolerance.

Plant Physiology
The transcriptional regulation of aluminum (Al) tolerance in plants is largely unknown, although Al toxicity restricts agricultural yields in acidic soils..

Mechanisms of Aluminum Tolerance

2010
Aluminum (Al) toxicity limits agricultural productivity over much of the world’s arable land by inhibiting root growth and development. Affected plants have difficulty in acquiring adequate water and nutrition from their soil environments and thus have stunted shoot development and diminished yield.

Growth and aluminum tolerance of maize roots mediated by auxin- and cytokinin-producing Bacillus toyonensis requires polar auxin transport

, 2020
Plant Growth Promotion Rhizobacteria (PGPR) control plant development by modulation of their phytohormone activities. To probe how PGPR trigger plant growth and mitigate stress induced by aluminum (Al), the beneficial effect of Bacillus toyonensis strain

Breeding for Aluminum Tolerance

2012
Aluminum (Al) toxicity is one of the greatest limitations to agriculture in acid soils, principally in the tropical regions. In these areas, crop management practices, including massive application of limestone, were adopted for the implementation of commercial agriculture.

Aluminum effects on photosynthesis and elemental uptake in an aluminum‐tolerant and non‐tolerant wheat cultivar

Journal of Plant Nutrition, 1995
Abstract The effects of aluminum (Al) on photosynthesis and elemental uptake were studied in two wheat cultivars (Triticum aestivum L. cvs Yecora E, Nestos) differing in their tolerance to Al. Concentrations of calcium (Ca), magnesium (Mg), potassium (K), and iron (Fe) in the plant tissues of both cultivars grown in nutrient solutions (pH 4.5 ...

Differential aluminum tolerance in some tropical rice cultivars. II. mechanism of aluminum tolerance

Journal of Plant Nutrition, 1993
Abstract Ten‐day‐old seedlings of 22 rice (Oryza sativa L.) cultivars were subjected to aluminum (Al) stress in nutrient solutions with an initial pH of 4.0±0.1. The rice cultivars exhibited a wide range of response by changing the rhizosphere pH, and the uptake and efficiency ratio (ER) of utilization of nutrients both in the presence (222 μM Al) and ...

The formate dehydrogenase enhances aluminum tolerance of tobacco

Journal of Genetics, 2023
The formate dehydrogenase (FDH) is regarded as a universal stress protein involved in various plant abiotic stress responses. This study aims to ascertain GmFDH function in conferring tolerance to aluminum (Al) stress. The bioinformatics analysis demonstrates that GmFDH from Tamba black soybean (TBS) encodes FDH. Quantitative reverse transcription-PCR (

Evaluation of Aluminum Tolerance in Rice

Journal of Crop Improvement, 2006
Abstract The objectives of the present work were to adjust the method for identifying genetic variability in rice through the use of minimal solution in hydroponic culture, and to identify the most important level and character for the study. The experiment consisted of the response evaluation of 18 rice genotypes to three levels of aluminum treatment.

Aluminum tolerance in sorghum

1987
Aluminum (Al) tolerance in sorghum (Sorghum bicolor (L.) Moench) was studied in nutrient solution, The relative seminal root lengths of lines from the World Collection (IS Numbers) and other sources suggested that a reasonable amount of genetic variation apparently exists in sorghum for tolerance to Al toxicity, The estimates of general and specific ...
