Aluminum (Al) is the most abundant metal in the earth's crust, but its availability depends on
soil pH. Despite this abundance, Al is not considered an essential element and so far no …

Aluminum (Al) toxicity in acid soils is a significant limitation to crop production worldwide, as
approximately 50% of the world's potentially arable soil is acidic. Because acid soils are …

The role of γ-aminobutyric acid (GABA) as a signal in animals has been documented for
over 60 years. In contrast, evidence that GABA is a signal in plants has only emerged in the …

▪ Abstract Acid soils significantly limit crop production worldwide because approximately
50% of the world's potentially arable soils are acidic. Because acid soils are such an …

Aluminum (Al) toxicity is the major factor limiting crop productivity on acid soils, which
comprise up to 40% of the world's arable lands. Also, many native and crop plants exhibit …

Aluminum (Al) is the most abundant metal in the earths crust, comprising about 7% of its
mass. Since many plant species are sensitive to micromolar concentrations of Al, the …

▪ Abstract The rhizosphere is the zone of soil immediately surrounding plant roots that is
modified by root activity. In this critical zone, plants perceive and respond to their …

Aluminum (Al) toxicity is the primary factor limiting crop production on acidic soils (pH values
of 5 or below), and because 50% of the world's potentially arable lands are acidic, Al toxicity …

The major constraint to plant growth in acid soils is the presence of toxic aluminum (Al)
cations, which inhibit root elongation. The enhanced Al tolerance exhibited by some …

Abstract Background Aluminium (Al) toxicity is the most important soil constraint for plant
growth and development in acid soils. The mechanism of Al-induced inhibition of root …
