Ethylene is a gaseous phytohormone and the first of this hormone class to be discovered. It
is the simplest olefin gas and is biosynthesized by plants to regulate plant development …

Adventitious roots are plant roots that form from any nonroot tissue and are produced both
during normal development (crown roots on cereals and nodal roots on strawberry [Fragaria …

Background Adventitious root (AR) formation in excised plant parts is a bottleneck for
survival of isolated plant fragments. AR formation plays an important ecological role and is a …

Background Stress-induced hormones are essential for plants to modulate their microbiota
and dynamically adjust to the environment. Despite the emphasis of the role of the …

The demand for increased crop productivity and the predicted challenges related to plant
survival under adverse environmental conditions have renewed the interest in research in …

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 …

Abscisic acid (ABA) increases reactive oxygen species (ROS) in guard cells to close
Arabidopsis (Arabidopsis thaliana) stomata. In tomato (Solanum lycopersicum), we find that …

Ethylene represents an important regulatory signal for root development. Genetic studies in
Arabidopsis thaliana have demonstrated that ethylene inhibition of root growth involves …

Lateral root (LR) formation, the production of new roots from parent roots, is a hormone-and
environmentally-regulated developmental process in higher plants. Physiological and …

Soil flooding, which results in a decline in the availability of oxygen to submerged organs,
negatively affects the growth and productivity of most crops. Although tomato (Solanum …
