Nitric Oxide Induces Autophagy in Roots.

Autophagy is a highly conserved process that degrades damaged macromolecules and organelles. Unlike animals, only scant information is available regarding nitric oxide (NO)-induced autophagy in plants. Such lack of information prompted us to study the roles of the NO donors' nitrate, nitrite, and sodium nitroprusside in this catabolic process in wheat roots.

Mdivi-1 Induced Mitochondrial Fusion as a Potential Mechanism to Enhance Stress Tolerance in Wheat.

Mitochondria play a key role in providing energy to cells. These organelles are constantly undergoing dynamic processes of fusion and fission that change in stressful conditions. The role of mitochondrial fusion in wheat root cells was studied using Mdivi-1, an inhibitor of the mitochondrial fragmentation protein Drp1.

Effect of respiratory inhibitors on mitochondrial complexes and ADP/ATP translocators in the Triticum aestivum roots.

Effective functioning of the mitochondrial complexes of the oxidative phosphorylation (OXPHOS) system is necessary for ATP synthesis. The OXPHOS complexes exist both as individual forms and supercomplexes, whose formation and stability are supported by specific protein and lipid factors. In this paper, we report on the types and activities of OXPHOS complexes and supercomplexes from wheat (Triticum aestivum L.

Mitochondrial morphology and dynamics in Triticum aestivum roots in response to rotenone and antimycin A.

Mitochondria are dynamic organelles, capable of fusion and fission as a part of cellular responses to various signals, such as the shifts in the redox status of a cell. The mitochondrial electron transport chain (ETC.) is involved in the generation of reactive oxygen species (ROS), with complexes I and III contributing the most to this process.
