Relationship between osmotic stress and the levels of free, conjugated and bound polyamines in leaves of wheat seedlings



Relationship between osmotic stress and the levels of free, conjugated and bound polyamines in leaves of wheat seedlings



Plant Science 166(5): 1261-1267



The changes in content and form of polyamines (PAs) in the leaves of two wheat (Triticum aestivum L.) cultivar seedlings, differing in drought tolerance, were investigated under osmotic stress. Yumai No. 18 (drought-tolerant) showed marked increases of free-spermidine (free-Spd) and free-spermine (free-Spm) levels in leaves after polyethylene glycol (PEG) 6000 treatment for 7 days, while Yangmai No. 9 (drought-sensitive) showed a significant increase of free-putrescine (free-Put) level.
