abstract = {Unfavorable environmental conditions limit plant growth and
require extensive adaptation for survival. During abiotic
stress, production of reactive oxygen species (ROS) can
increase and create additional oxidative stress for the
plants. Mitochondria regulate cellular energy homeostasis
and redox balance by integrating metabolic pathways that are
important in adaptive responses to stress conditions. In
mitochondria, over-reduction of the electron transport chain
is the primary reason for ROS accumulation, which can be
reduced by protecting and stabilizing the electron flow. To
reveal the function of genes encoding members of the
mitochondrial electron transport in stress responses, we are
characterizing 13 Arabidopsis thaliana mutants carrying
mutations in genes encoding such proteins. When compared to
wild type several mutants showed morphological and
physiological changes under abiotic stress conditions.
Phenotypic differences in tolerance to drought and salinity
were revealed through in vitro germination and growth tests,
as well as by complex phenotyping of soil-grown plants.
Several mutants showed altered tolerance to osmotic,
oxidative and salt stress. In some cases, we found a strong
correlation between the mutations and the photosynthetic
activity and energy production.},
