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 …

Fleshy fruit acidity is an important component of fruit organoleptic quality and is mainly due
to the presence of malic and citric acids, the main organic acids found in most ripe fruits. The …

The non-protein amino acid γ-aminobutyric acid (GABA) has been proposed to be an
ancient messenger for cellular communication conserved across biological kingdoms. GABA …

Deciphering the mechanism of malate accumulation in plants would contribute to a greater
understanding of plant chemistry, which has implications for improving flavor quality in crop …

Background Agricultural production is often limited by low phosphorus (P) availability. In
developing countries, which have limited access to P fertiliser, there is a need to develop …

Stomatal pores are formed by pairs of specialized epidermal guard cells and serve as major
gateways for both CO2 influx into plants from the atmosphere and transpirational water loss …

Stomatal guard cells are widely recognized as the premier plant cell model for membrane
transport, signaling, and homeostasis. This recognition is rooted in half a century of research …

This review evaluates the importance of root exudates in determining rhizosphere bacterial
community structure. We present evidence that indicates that:(1) the direct influence of root …

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 …

In response to drought stress the phytohormone ABA (abscisic acid) induces stomatal
closure and, therein, activates guard cell anion channels in a calcium-dependent as well as …
