The occurrence and possible function of hydroxycinnamoyl acid amides in plants
In recent years polyamines have been shown to participate in various aspects of plant growth processes [1, 2, 4, 5, 14, 28, 67, 68, 69, 71]. In general, free putrescine, spermidine and spermine wereExpand

Stress‐induced changes in polyamine and tyramine levels can regulate proline accumulation in tomato leaf discs treated with sodium chloride
The effect of salt stress on proline (Pro) accumulation and its relationship with the changes occurring at the level of polyamine (PA) metabolism and tyramine were investigated in leaf discs ofExpand

Salt stress-induced proline accumulation and changes in tyramine and polyamine levels are linked to ionic adjustment in tomato leaf discs
Abstract The changes induced in the levels of proline, tyramine and polyamines in response to salt (NaCl) shock treatments were studied using tomato ( Lycopersicon esculentum Mill.) leaf discsExpand
