Many trace metals are essential micronutrients, but also potent toxins. Due to natural and
anthropogenic causes, vastly different trace metal concentrations occur in various habitats …

Strigolactones are rhizosphere signals and phytohormones that play crucial roles in plant
development. They are also well known for their role in integrating nitrate and phosphate …

Abstract Trehalose 6-phosphate (Tre6P), the intermediate of trehalose biosynthesis, is an
essential signal metabolite in plants, linking growth and development to carbon status. The …

Under the natural environment, nutrient signals interact with phytohormones to coordinate
and reprogram plant growth and survival. Sugars are important molecules that control …

Sugars have a central regulatory function in steering plant growth. This review focuses on
information presented in the past 2 years on key players in sugar-mediated plant growth …

For almost a century the plant hormone auxin has been central to theories on apical
dominance, whereby the growing shoot tip suppresses the growth of the axillary buds below …

Phytochrome-interacting factors (PIFs) are members of the Arabidopsis thaliana basic helix-
loop-helix family of transcriptional regulators that interact specifically with the active Pfr …

Auxin plays important roles during the entire life span of a plant. This small organic acid
influences cell division, cell elongation and cell differentiation, and has great impact on the …

Plant growth and development has to be continuously adjusted to the available resources.
Their optimization requires the integration of signals conveying the plant metabolic status, its …

Plant responses to atmospheric carbon dioxide will be of great concern in the future, as
carbon dioxide concentrations ([CO2]) are predicted to continue to rise. Elevated [CO2] …
