Flavonoids are a special category of hydroxylated phenolic compounds having an aromatic
ring structure. Quercetin is aspecial subclass of flavonoid. It is a bioactive natural compound …

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

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 …

Variation in xylem vessel diameter is one of the most important parameters when evaluating
plant water relations. This review provides a synthesis of the ecophysiological implications …

Auxin is a plant hormone involved in an extraordinarily broad variety of biological
mechanisms. These range from basic cellular processes, such as endocytosis, cell polarity …

The old observation that plants preferentially synthesize flavonoids with respect to the wide
range of phenylpropanoid structures when exposed to high doses of UV-B radiation has …

The decade since the publication of the third edition of this volume has been an era of great
progress in biology in general and the plant sciences in particular. This is especially true …

Adventitious root (AR) formation in cuttings is a multiphase developmental process, resulting
from wounding at the cutting site and isolation from the resource and signal network of the …

In this review, we summarize the different biosynthesis-related pathways that contribute to
the regulation of endogenous auxin in plants. We demonstrate that all known genes …

Abscisic acid (ABA) metabolism, perception, and transport form a triptych allowing higher
plants to use ABA as a signaling molecule. The molecular bases of ABA metabolism are …
