Arabidopsis thaliana COPT transporters function in hormone metabolism and in metal stress

2017

Proper copper (Cu) homeostasis is required by living organisms to maintain essential cellular functions. In the model plant Arabidopsis thaliana, the high affinity Cu transporters (COPT) family play a key role in Cu transport under Cu deficiency conditions. In this thesis, we are going to study how affect an altered Cu transport to hormone metabolism and other metal homeostasis using different copt mutants. Plant hormone act as major endogenous cues that regulates morphological, physiological and molecular adaptive responses to environmental changes. Abscisic acid (ABA) is involved in plant responses to non-optimal environmental conditions, including nutrient availability. Since Cu is an im…
