Isolated thylakoids from halophytic Eutrema salsugineum (Thellungiella salsuginea) produces more H2O2 in comparison to glycophytic Arabidopsis thaliana. The first objective of this study was to verify whether this feature is relevant also to the intact chloroplasts and leaves. Enhanced H2O2 levels in chloroplasts and leaves of E. salsugineum were positively verified with several methods (electr...
The alteration in gene expression that occurs in plants subjected to water shortage has been documented extensively (Skriver and Mundy, 19901, and gene cloning and sequencing has shed some light on the molecular processes that may protect cells from the harmful effects of osmotic stress (Bray, 1991, 1993). Since plant hormones such as ABA and jasmonate are in some cases capable of causing expre...
Soil salinity severely threatens land use capability and crop yields worldwide. An analysis of the molecular mechanisms of salt tolerance in halophytes will contribute to the development of salt-tolerant crops. In this study, a combination of physiological characteristics and iTRAQ-based proteomic approaches was conducted to investigate the molecular mechanisms underlying the salt response of s...
Cellular Na(+)/K(+) ratio is a crucial parameter determining plant salinity stress resistance. We tested the function of plasma membrane Na(+)/K(+) cotransporters in the High-affinity K(+) Transporter (HKT) family from the halophytic Arabidopsis (Arabidopsis thaliana) relative Thellungiella salsuginea. T. salsuginea contains at least two HKT genes. TsHKT1;1 is expressed at very low levels, whil...
Anthropogenic disturbances in nature can be defined by energy and emergy terms. I studied four saline meadows with different protection status to see if they differ in species richness and plant biomass of halophytes and in the level of anthropogenic disturbance. The four studied meadows were located in the Kujawy region, the central part of Poland. The first study area was the reserve of halop...
