A zinc finger transcription factor HvATF1 regulates aluminum tolerance in barley.

Journal of Experimental Botany, 2020
Aluminum (Al) toxicity is a major abiotic stress restricting crop production in acid soils. To detoxify Al stress, plants adopt internal and external mechanisms of Al tolerance.

The role of solute transporters in aluminum toxicity and tolerance

Physiologia Plantarum, 2020
The prevalence of aluminum ions (Al3+) under acidic soil conditions inhibits primary root elongation and hinders plant growth and productivity. Al3+ alters the membrane potential, displaces critical ions in the apoplast and disrupts intracellular ionic concentrations by targeting membrane‐localized solute transporters.

Screening of grape genotypes for aluminum tolerance and evaluation on selecting indices

Soil science and plant nutrition (Tokyo), 2020
Grape is intolerant of aluminum. This intolerance leads to severe aluminum poisoning when the plants are cultivated in acidic soil, resulting in a decline in their yield and quality.

INHERITANCE OF ALUMINUM TOLERANCE IN WHEAT

Canadian Journal of Genetics and Cytology, 1978
Aluminum tolerant and aluminum sensitive wheat (Triticum aestivum L. em Thell) cultivars representing different parental backgrounds were used to study the inheritance of response to aluminium. F1, F2, F3, and backcross generations from crosses of four soft red winter wheat cultivars were grown in nutrient solutions containing 8 ppm aluminum.

Effect of aluminum stress on the expression of calmodulin and the role of calmodulin in aluminum tolerance

Journal of Bioscience and Bioengineering, 2016
Calmodulin (CaM) is a calcium ion-binding protein that regulates a variety of cellular functions through its downstream target proteins. Previous studies have reported that overexpression of CaM enhances tolerance to stress, including resistance to salt, heat, cold, drought and plant pathogens.

Increased bound putrescine accumulation contributes to the maintenance of antioxidant enzymes and higher aluminum tolerance in wheat.

Environmental Pollution, 2019
The accumulation of bound and conjugated polyamines (PAs) is an important protective trait in plants under adverse environmental conditions. However, their role in plant responses to aluminum (Al) stress remains largely unknown.

Organic acid excretion from roots: a plant mechanism for enhancing phosphorus acquisition, enhancing aluminum tolerance, and recruiting beneficial rhizobacteria

Soil science and plant nutrition (Tokyo), 2018
The beneficial effects of organic acids (OAs) excretion from plant roots were first proposed as being associated with the mechanism of superior phosphorus utilization by the cluster roots of white lupin (Lupinus albus L.), and these effects are now ...

Biotechniques for improving acid aluminum tolerance in alfalfa

Plant Cell Reports, 1993
Alfalfa (Medicago sativa L.), cultivars ARC, Regen Y and Saranac were selected in vitro in a recently developed acid/aluminum toxic media. The new media produced higher initiation rates and higher fresh callus weights than those obtainable with the media described by Meredith and Connor for the selection of aluminum resistant variants in Nicotiana ...

Making Plants Aluminum Tolerant

Science, 1997
Aluminum toxicity is a major problem to agricultural crops, affecting some 30% to 40% of the world9s arable lands and reducing yields by as much as 80%. Now, Mexican researchers have come up with a possible genetic-engineering fix. They report on page 1566 of this issue of Science that they were able to make tobacco and papaya plants ...

Modification of DNA Checkpoints to Confer Aluminum Tolerance

Trends in Plant Science, 2017
Although aluminum (Al) toxicity represents a global agricultural problem, the biochemical targets for Al remain elusive. Recently identified Arabidopsis mutants with increased Al tolerance provide evidence of DNA as one of the main targets of Al. This insight could lead the way for novel strategies to generate Al-tolerant crop plants.
