It is well known that nutrient availability controls plant development. Moreover, plant development is finely tuned by a myriad of hormonal signals. Thus, it is not surprising to see increasing evidence of coordination between nutritional and hormonal signaling. In this opinion article, we discuss how nitrogen signals control the hormonal status of plants and how hormonal signals interplay with...

Plant growth regulators are hormone-like chemicals that occur naturally in plants, and play a central role in their growth and development. Five major classes of plant growth regulators have been identified as plant hormones, but scientists believe that there are more waiting to be discovered. The five growth hormones include auxins, gibberellins, cytokinins, abscisic acid, and ethylene. Collec...

Being sessile organisms, plants usually have little control over their immediate growth environment. Responses to environmental and developmental factors need to be rapid and finely coordinated to trigger the necessary morphological and metabolic changes that ensure plant survival and growth. Many of these adaptive responses are mediated by plant hormones. Recent work has shown that ubiquitin-m...

The diverse effects of the plant hormone ethylene on development and growth are shaped by the actions of a master regulator of transcription, EIN3.

Plant hormones play an important role in plant response to abiotic stresses, by both stimulation of defence pathways and regulation of plant growth and development. The key hormone in the response to stresses associated with dehydration is abscisic acid (ABA). Its levels were followed during the response to salinity or drought in two species differing in their stress tolerance – radish and toba...

Phytohormones act in concert to coordinate plant growth and the response to environmental cues. Gibberellins (GAs) are growth-promoting hormones that recently emerged as modulators of plant immune signaling. By regulating the stability of DELLA proteins, GAs intersect with the signaling pathways of the classical primary defense hormones, salicylic acid (SA) and jasmonic acid (JA), thereby alter...
