Inhibition of root growth by spermidine is not due to enhanced production of ethylene

Autor: Marina de Agazio, Elvira Rea, Giovanna di Monte

Publikováno v: Plant Science. 108:121-124

Pretreatment of 3-day-old maize seedlings with spermidine induces an enhancement of ethylene production from roots compared to control tissues with no effect on 1-aminocyclopropane-1-carboxylate oxidase activity and 1-aminocyclopropane-1-carboxylic a

Spermidine Pretreatment or Root Tip Removal in Maize Seedlings: Effects on K+ Uptake and Tissue Modifications

Autor: Rodolfo Federico, Fabrizio De Cesare, Riccardo Angelini, Marina de Agazio, Stefano Grego

Publikováno v: Journal of Plant Physiology. 140:741-746

Summary Three-day-old maize seedlings were transferred to fresh growth solution with or without spermidine (Spd), or had the primary root tip removed and were then transferred to fresh growth solution. Spd pretreatment resulted in 50 % inhibition of

In order to further study a previously observed relationship between polyamine (PA) content and changes in irradiation, we examined the level of free and bound PAs, the activity of transglutaminase (TGase, EC 2.3.2.13) and chlorophyll fluorescence in
