Salt-sensitive and salt-tolerant barley varieties differ in the extent of potentiation of the ROS-induced K+ efflux by polyamines

Popis výsledku v původním jazyce

Generation of high levels of polyamines and reactive oxygen species (ROS) is common under stress conditions. Our recent study on a salt-sensitive pea species revealed an interaction between natural polyamines and hydroxyl radicals in inducing non-selective conductance and stimulating Ca2+-ATPase pumps at the root plasma membrane (I. Zepeda-Jazo, A.M. Velarde-Buendía, R. Enríquez-Figueroa, B. Jayakumar, S. Shabala, J. Mu?iz, I. Pottosin, Polyamines interact with hydroxyl radicals in activating Ca2+ and K+ transport across the root epidermal plasma membranes, Plant Phys. 157 (2011) 1?14). In this work, we extended that study to see if interaction between polyamines and ROS may determine the extent of genotypic variation in salinity tolerance. This work was conducted using barley genotypes contrasting in salinity tolerance. Similar to our findings in pea, application of hydroxyl radicals-generating Cu2+/ascorbate mixture induced transient Ca2+ and K+ fluxes in barley roots. Putrescine and
