| dc.description.abstract | Maintenance of growth, development and normal physiological processes remains crucial
for the survival of plants. Plant hormones are described as integrators of external signal
and internal developmental process in plants. They also attribute as mediators of
physiological and developmental adaptation throughout the plant life cycle (Wilkinson et
al.,1997).
It has been well over 50 years since Went and Thimann (1937) published their classical
book Phytohorrnones. At that time, the term phytohorrnone was synonymous to auxin,
although compounds like cell division factors were anticipated to be phytohormones
based on physiological experiments. Since then a number of plant hormones were
discovered and a series of studies concluded that plant hormones are at least partly
responsible for plant growth, development, cell elongation, cell division, differentiation
and stomatal movement in response to environmental stimuli. Plant hormones are
categorized into three groups, known as classical, non-classical and peptide hormones.
Here, Plant Natriuretic Peptide (PNP) will be reviewed as a proposed additional peptide
hormone. | en_US |
