Advances in the Molecular Mechanisms of Abscisic Acid and Gibberellins Functions in Plants 2.0

<p>Gibberellins (GA) and abscisic acid (ABA) are two phytohormones that regulate in an antagonistic way plant growth as well as several developmental processes from seed maturation and germination to flowering time through hypocotyl elongation and root growth. In general ABA and GA inhibit and promote respectively cell elongation and growth. Consequently this mutual antagonism between GA and ABA governs many developmental decisions in plants. In addition to its role as a growth and development modulator ABA is primarily known for being a major player in the response and adaptation of plants to diverse abiotic stress conditions including cold heat drought salinity or flooding. Remarkably different works have also recently pointed to a function for GA in the control of some biological processes in response to stress. The selection of research and review papers of this book mostly focused on ABA covers a wide range of topics related to the most recent advances in the molecular mechanisms of ABA and GA functions in plants.</p>
