Celery (Apium graveolens) can be considered as a model plant for studying pectin-enriched primary cell walls. In addition to parenchyma cells with xyloglucan-deficient walls, celery petioles contain collenchyma, mechanical tissue thickened walls of similar composition. This study presents comprehensive analysis these tissues at both early and late developmental stages, integrating data on polysaccharide yield, composition, localization, transcriptome analysis. Our results reveal that young...
Contractile cell walls are found in various plant organs and tissues such as tendrils, contractile roots, tension wood. The tension-generating mechanism is not known but thought to involve special wall architecture. We previously postulated that could result from the entrapment of certain matrix polymers within cellulose microfibrils. As reported here, this hypothesis was corroborated by sequential extraction analysis retained microfibrils wood normal hybrid aspen (Populus tremula × Populus...
A positive effect of flaxseed mucilage (FSM) addition (at concentrations 0.1, 0.2, and 0.4%) to MRS milk whey nutrient medium on the survival, auto-aggregation, hydrophobicity, adhesive, antioxidant properties L. bulgaricus, fermentum AG8, plantarum AG9 was shown. It found that AG 8 strain became less sensitive 7% NaCl (the cell survival rate in experiment with 0.4% increased by 10% compared control). Cultivation presence FSM led an increase especially case AG8 (from 60 85%) 50 80%) strains,...
The exopolysaccharides (EPS) produced by lactic acid bacteria (LAB) and released into fermented milk play a protective role from stress factors as well improve emulsifying thickening properties of the product, reduce syneresis, increase elasticity. Here we report relationship between properties, composition, microstructure EPS six different strains lactobacilli (L. bulgaricus five isolated silage). presence fructose together with negative-charged uronic was found to significant in changing...
Disruption of cholinesterases and, as a consequence, increased levels acetylcholine lead to serious disturbances in the functioning nervous system, including death. The need for rapid administration an antidote restore esterase activity is critical, but practical implementation this often difficult. One promising solution may be development delivery systems that will release drug only when are elevated. This approach ensure timely and minimize side effects associated with uncontrolled...
In the present study, we identified exopolysaccharides of harmful phytopathogenic bacterium Pectobacterium atrosepticum SCRI1043 and characterized molecular structure these polymers. The synthesis target polysaccharides was shown to be induced under starvation conditions. Moreover, intensive accumulation occurred during colonization by bacteria xylem vessels infected plants, where microorganisms formed specific 3D "multicellular" structures-bacterial emboli. Thus, polymers are likely...
Abstract Representatives of Pectobacterium genus are some the most harmful phytopathogens in world. In present study, we have elucidated novel aspects plant– atrosepticum interactions. This bacterium was recently demonstrated to form specific ‘multicellular’ structures – bacterial emboli xylem vessels infected plants. our work, showed that process formation these includes pathogen‐induced reactions plant. The colonisation plant by P. is coupled with release a pectic polysaccharide,...
The phytopathogenic bacterium Pectobacterium atrosepticum (Pba), one of the members soft rot Pectobacteriaceae, forms biofilm-like structures known as bacterial emboli when colonizing primary xylem vessels host plants. initial extracellular matrix is composed plant’s pectic polysaccharides, which are gradually substituted by Pba-produced exopolysaccharides (Pba EPS) “mature”. No information about properties Pba EPS and their possible roles in Pba-plant interactions has so far been obtained....
