The significance of root exudates as belowground defense substances has long been
underestimated, presumably due to being buried out of sight. Nevertheless, this chapter of …

Terrestrial plants have two to four times more ATP-binding cassette (ABC) transporter genes
than other organisms, including their ancestral microalgae. Recent studies found that plants …

Glyphosate is the most widely used herbicide in world agriculture and for general vegetation
control in a wide range of situations. Global and often intensive glyphosate selection of very …

The plant hormone auxin promotes cell expansion. Forty years ago, the acid growth theory
was proposed, whereby auxin promotes proton efflux to acidify the apoplast and facilitate the …

Long before its chemical identity was known, the phytohormone auxin was postulated to
regulate plant growth. In the late 1800s, Sachs hypothesized that plant growth regulators …

ABC transporters constitute one of the largest protein families found in all living organisms.
ABC transporters are driven by ATP hydrolysis and can act as exporters as well as …

The plant hormone auxin controls numerous aspects of plant growth and development by
regulating the expression of hundreds of genes. SMALL AUXIN UP RNA (SAUR) genes …

Dichlorophenoxyacetic acid (2, 4‐D) was the first synthetic herbicide to be commercially
developed and has commonly been used as a broadleaf herbicide for over 60 years. It is a …

The ABC superfamily comprises both membrane-bound transporters and soluble proteins
involved in a broad range of processes, many of which are of considerable agricultural …

Iron (Fe) deficiency-induced chlorosis is a major nutritional disorder in crops growing in
calcareous soils. Iron deficiency in fruit tree crops causes chlorosis, decreases in vegetative …
