context_page_description: Polyamines are small, positively charged, organic molecules that are ubiquitous in all living organisms. These are considered as one of the oldest group of substances known in biochemistry. There are three common types of polyamines, putrescine, spermidine, hermospermine according to structure, universal distribution in all cellular compartments, and presumed involvement in physiological activities. Polyamine is found in all cellular compartments and physiological activities due to their simple structures. The function of polyamine is very diverse in that it performs a key macromolecule to cellular membrane. Because of their essential roles in plant, mutation of polyamines can cause critical damage on plants. Furthermore, some polyamines like putrescine inhibit biosynthetic activities in plants. The activity of polyamines can be categorized to some parts due to its signalling and growing activity.
context_section_description: Polyamines, which are the key compounds in plant physiology, play essential role in cell proliferation, growth and differentiation. They also carry out significant effects on embryo/fetus proliferation, implantation, embryonic diapause, placentation, angiogenesis and fetal development.
