Prof. Dr. Gábor Kalácska - MATE Research
Overview
Gábor Kalácska's main research area is at the intersection of mechanical engineering, farm-engineering, and material science. More specifically, it delves into the investigation of tribological issues associated with the technical reliability of machine systems and their operational lifespan. This encompasses the study of friction and wear in machine components, lubrication, as well as the development and application technology of tribological systems. Within the realm of materials science, the research focuses on the tribological characteristics of polymers and composites. Furthermore, it explores the abrasive processes in farm-engineering and their applications in aerospace (space tribology research).

Publications
The Medicago truncatula nodule-specific cysteine-rich peptides, NCR343 and NCR-new35 are required for the maintenance of rhizobia in nitrogen-fixing nodules
Loss of the nodule-specific cysteine rich peptide, NCR169, abolishes symbiotic nitrogen fixation in the Medicago truncatula dnf7 mutant
Host-secreted antimicrobial peptide enforces symbiotic selectivity in Medicago truncatula
We are also characterizing and analyzing M. truncatula mutants defective in the earlier or later stages of nodule organogenesis: how the rhizobia and the plant communicate to start the interaction and also what happens if a nodule-specific Vacuolar iron Transporter-Like (VTL) protein is not present in the nodule. Differentiation and nitrogen fixation is strictly regulated processes; any step is failed no functional nodule is formed.
The Medicago truncatula Vacuolar iron Transporter-Like proteins VTL4 and VTL8 deliver iron to symbiotic bacteria at different stages of the infection process
Amino Acid Polymorphisms in the VHIID Conserved Motif of Nodulation Signaling Pathways 2 Distinctly Modulate Symbiotic Signaling and Nodule Morphogenesis in Medicago truncatula
Our research is focusing also on the repression of the immune reaction during nodule formation.
Suppression of NB-LRR genes by miRNAs promotes nitrogen-fixing nodule development in Medicago truncatula
NAD1 controls defense-like responses in Medicago truncatula symbiotic nitrogen fixing nodules following rhizobial colonization in a BacA-independent manner
Researching new resistance genes in crop plants and cultivated vegetables is always a is always a crucial topic.
Projects
Tribological research on High-Performance Materials (HPM) and their composites
Engaged in the TéT bilateral Flemish-Hungarian research cooperation, he holds the position of the head of the Hungarian research group. The project involves an investigation into the overload tribological characteristics of various HPM and composite materials in case of different movement conditions.
