Stress and Polyamine Metabolism
The polyamines (PAs) putrescine (Put), spermidine (Spd) and spermine (Spm) (Fig. 1) have been shown to be involved in a variety of plant growth and developmental processes, including cell division, vascular differentiation, root initiation, shoot formation, flower initiation and development, fruit ripening and senescence and embryoid formation in tissue cultures (Evans and Malmberg, 1989; Galst...
متن کاملStress and polyamine metabolism in fungi
Fungi, as well as the rest of living organisms must deal with environmental challenges such as stressful stimuli. Fungi are excellent models to study the general mechanisms of the response to stress, because of their simple, but conserved, signal-transduction and metabolic pathways that are often equivalent to those present in other eukaryotic systems. A factor that has been demonstrated to be ...
متن کاملRecent Advances in Polyamine Metabolism and Abiotic Stress Tolerance
Global warming is an alarming problem in agriculture and its effect on yield loss has been estimated to be five per cent for every degree centigrade rise in temperature. Plants exhibit multiple mechanisms like optimizing signaling pathway, involvement of secondary messengers, production of biomolecules specifically in response to stress, modulation of various metabolic networks in accordance wi...
متن کاملPolyamine metabolism and signaling in plant abiotic stress protection
Polyamines (PAs) are small polycationic compounds present in all living organisms. Compelling evidences indicate a role for PAs in plant protection against stress. During the recent years, genetic, molecular and ‘omic’ approaches have been undertaken to unravel the role of PAs in stress signaling. Overall, results point to intricate relationships between PAs, stress hormone pathways and ROS sig...

PEGG, ANTHONY E., AND PETER P. MCCANN. PoZyamine metabohsm and function. Am. J. Physiol. 243 (Cell Physiol. 12): C212-C221, 1982.Polyamines are ubiquitous organic cations of low molecular weight. The content of these amines is closely regulated by the cell according to the state of growth. The reactions responsible for the biosynthesis and interconversion of the polyamines and their precursor p...
