| The involvement of RNases in senescence, abscission and programmed cell death processes in plants. |
The T2 RNases are highly conserved enzymes, found in a wide variety of organisms but their specific biological functions are largely unknown. The function and regulation of T2-RNases in senescence, PCD and biotic/abiotic stress is investigated. The possible involvement of these RNases in regulation of RNA stability is explored.

| The Biological and Genetic Basis for Postharvest Chilling Injury Development in Stored Fruits |
Crops stored at low temperature may suffer chilling injury resulting with physiological disorders/decay. Research is performed to investigate the physiological, biochemical, molecular and genetic basis for fruit sensitivity/tolerance to chilling stress in fruits and identify biological mechanisms/genes which have a role in determining fruit chilling sensitivity/tolerance.

| Physiology and biotechnology of potato starch |
Potato, one of the most important starch crops, widely used as a staple food throughout the world. Starch, the major storage compound in potato tubers, ranging from 10% to 25% of its fresh weight. Its accumulation is a complex developmental process that depends mainly on genetic factors. In this project we will use omics combined with target genomics (CRISPR/Cas9) and biochemistry methods to study starch synthesis and degradation in pre and postharvest potato tubers.

| Molecular aspects of regulation of mycotoxin biosynthesis by Penicillium expansum in colonized fruits |
Penicillium expansum is a destructive phytopathogen that causes decay in a wide range of fruits and vegetables. During colonization, the fungus produces large amounts of the mycotoxin patulin. The overall goal of this proposal is to identify critical host and pathogen factors that mechanistically modulate P. expansum genes and pathways to control activation of patulin production and virulence in host. The elucidation of such mechanisms will stimulate new approaches to postharvest disease control, as patulin reduction could result in reduced fungal capability to decay fruit during storage and present improved health outcomes for consumers.

| Developing edible probiotic biofilm as a source for novel healthy food generated by probiotic Bacilli |
Live probiotic bacteria grown in biofilm mode of growth could provide a platform for developing a quality food that would provide essential components as well as vitamins for host organism and may reduce intestinal colonization by pathogens. To ensure its beneficial effects, microorganisms structured into the probiotic biofilm would survive the passage through the upper gastrointestinal tract, and subsequent chemical ingestion processes until they reach their target organ. Thus, we aim to developing novel approach for generating probiotic healthy food through symbiotic interactions between probiotic Bacilli during probiotic biofilm formation, which antagonize establishment of pathogenic bacteria.

| Investigation mode of interaction during formation of multispecies biofilm by probiotic Bacilli |
We study complex interactions that take place within symbiotic biofilms formed by the probiotic Bacilli. We have noticed that there is notable induction in biofilm formation by B. subtilis cells during their growth along with lactic acid bacteria (LAB). Apparently, signaling molecules emerged during cellular metabolism of LAB are somehow involved in triggering biofilm formation process by B. subtilis cells. Our initial metabolic profiling indicates about production of several molecules that could be used for induction in biofilm formation by B. subtilis cells. Thus, we investigate different molecules produced during the symbiotic interactions, which could play a role in generating multispecies biofilm community by B. subtilis and LAB.

| Developing novel antimicrobial approach improving quality of dairy food |
This approach involves inhibition of the signal transduction pathway for biofilm formation. We found a way to inhibit specifically biofilm formation by downregulating expression of extracellular matrix genes. Moreover, we discovered that by mitigating biofilm formation bacteria become very sensitive to heat treatment. This finding contributes to the development of novel effective pasteurization procedures for milk and its products. We are currently collaborating with different food companies to implement this new technology into industrial settings.

| Developing new probiotics |
Live probiotic bacteria obtained with food are thought to reduce intestinal colonization by pathogens. To ensure their beneficial effects, these organisms must survive processing and storage of food, its passage through the upper gastrointestinal tract (GIT), and subsequent chemical ingestion processes until they reach their target organ. However, there is considerable loss in viability of probiotic bacteria in the acidic conditions of the stomach and the high bile concentration in the small intestine. We aim therefore to develop live-encapsulation approach through symbiotic interactions between probiotic Bacilli that antagonize establishment of pathogenic bacteria.
