Plant hormones

Plant hormones have been studied for more than a century because they have been heavily implicated in the control of plant growth and development. For many years, they have been considered to fall into five classes: auxins, cytokinins, gibberellins, abscisic acid and ethylene. More recently, a variety of additional classes such as brassinosteroids have been added and it seems likely that more w...

Bacteria-host communication: the language of hormones.

The interbacterial communication system known as quorum sensing (QS) utilizes hormone-like compounds referred to as autoinducers to regulate bacterial gene expression. Enterohemorrhagic Escherichia coli (EHEC) serotype O157:H7 is the agent responsible for outbreaks of bloody diarrhea in several countries. We previously proposed that EHEC uses a QS regulatory system to "sense" that it is within ...

The Five "Classical" Plant Hormones.

It is 60 years since Went and Thimann (1937) published their classic book Phytohormones. At that time, the term phytohormone was synonymous with auxin, although the existente of other phytohormones, such as cell division factors, was anticipated on the basis of physiological experiments. It is impressive that aside from some confusion about the structure of auxin, many of the basic phenomena of...
