Aluminum (Al) is the third most ubiquitous metal in the earth's crust. A decrease in soil pH
below 5 increases its solubility and availability. However, its impact on plants depends …

Plants confront multifarious environmental stresses widely divided into abiotic and biotic
stresses, of which heavy metal stress represents one of the most damaging abiotic stresses …

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 …

Aluminum (Al) is the most prevalent element in the earth crust and is toxic to plants in acidic
soils. However, plants can address Al toxicity through external exclusion (which prevents Al …

The transition zone (TZ) of the root apex is the perception site of Al toxicity. Here, we show
that exposure of Arabidopsis thaliana roots to Al induces a localized enhancement of auxin …

While the proposal that γ-aminobutyric acid (GABA) acts a signal in plants is decades old, a
signaling mode of action for plant GABA has been unveiled only relatively recently. Here, we …

During the last 50 years, it has been shown that abiotic stresses influence plant growth and
crop production greatly, and crop yields have evidently stagnated or decreased in …

The phytohormone ethylene is known to mediate a diverse array of signaling processes
during abiotic stress in plants. Whereas many reports have demonstrated enhanced …

The signaling role for γ-Aminobutyric acid (GABA) has been documented in animals for over
seven decades. However, a signaling role for GABA in plants is just beginning to emerge …

Microorganisms colonizing the plant rhizosphere and phyllosphere play crucial roles in plant
growth and health. Recent studies provide new insights into long-distance communication …
