Background Plants depend on their root systems to acquire the water and nutrients
necessary for their survival in nature, and for their yield and nutritional quality in agriculture …

Acid soil is a worldwide problem to plant production. Acid toxicity is mainly caused by a lack
of essential nutrients in the soil and excessive toxic metals in the plant root zone. Of the toxic …

Despite significant progress in increasing agricultural production, meeting the changing
dietary preferences and increasing food demands of future populations remain significant …

Since the publication of the third edition of the Handbook of Plant and Crop Stress,
continuous discoveries in the fields of plant and crop environmental stresses and their …

ESTIMATES of the global carbon dioxide balance have identified a substantial'missing
sink'of 0.4–4.3 Gt per year1. It has been suggested that much of this may reside in the …

Aluminum (Al) tolerance in Arabidopsis is a genetically complex trait, yet it is mediated by a
single physiological mechanism based on Al-activated root malate efflux. We investigated a …

Low pH, aluminum (Al) toxicity, and low phosphorus (P) often coexist and are
heterogeneously distributed in acid soils. To date, the underlying mechanisms of crop …

Acid soil syndrome causes severe yield losses in various crop plants because of the
rhizotoxicities of ions, such as aluminum (Al3+). Although protons (H+) could be also major …

Clearing of natural vegetation for pastures and the deliberate introduction of African grasses
constitute significant threats to the biological diversity of the tropics, subtropics, and warm …

Selection of modern varieties has typically been performed in standardized, high fertility
systems with a primary focus on yield. This could have contributed to the loss of plant genes …
