• Hydrogen peroxide (H2O2) is reported to inhibit biotrophic but benefit necrotrophic pathogens. Infection by necrotrophs can result in a massive accumulation of H2O2 hosts. Little known how pathogens with both growth types are affected (hemibiotrophs). The hemibiotroph, Septoria tritici, infecting wheat (Triticum aestivum) inhibited during the phase, large occurs host reproduction. Here, we infiltrated catalase, or water into phase S. tritici and studied effect infection on physiology get...
An Arabidopsis thaliana gene encoding a homologue of the potato alpha-glucan, water dikinase GWD, previously known as R1, was identified by screening genome and named AtGWD3. The AtGWD3 cDNA isolated, heterologously expressed protein purified to apparent homogeneity determine enzymatic function. In contrast GWD protein, primarily catalysed phosphorylation at C-3 position glucose unit preferably pre-phosphorylated amylopectin substrate with long side chains. mutant, termed Atgwd3,...
Bacterial biofilm represents a major problem in medicine. They colonize and damage medical devices implants and, many cases, foster development of multidrug-resistant microorganisms. Biofilm starts by bacterial attachment to the surface production extracellular polymeric substances (EPS). The EPS forms structural scaffold for dividing cells. layers also play protective role, preventing access antibiotics biofilm-associated aim this work was investigate nanoparticles that could be used...
Abstract The root oncogenic loci ( rol ) C oncogene has been identified as a key player during the plant‐ Rhizobium rhizogenes interaction and is considered to confer resistance plant abiotic stresses, yet underlying mechanisms remain largely elusive. In this study, Arabidopsis plants constitutively overexpressing were produced. Biometric analysis showed that induced diverse phenotypic modifications, including dwarfism, increased number of stem branches (1.3 times more than WT), weak growth,...
Interspecific hybridization is a useful tool in ornamental breeding to increase genetic variability and introduce new valuable traits into existing cultivars. The successful formation of interspecific hybrids frequently limited by the presence pre- post-fertilization barriers. In present study, we investigated nature barriers occurring crosses between Kalanchoë species evaluated possibilities obtaining hybrids. qualitative quantitative analyses pollen tube growth situ were performed...
Abstract Hairy root (HR) cultures are quickly evolving as a fundamental research tool and bio-based production system for secondary metabolites. In this study, an efficient protocol establishment elicitation of anthocyanin-producing HR from black carrot was established. Taproot hypocotyl explants four cultivars were transformed using wild-type Rhizobium rhizogenes. growth performance on plates monitored to identify three fast-growing lines, two originating (lines NB-R 43-R) one explant (line...
Black carrots (Daucus carota ssp. sativus var. atrorubens Alef.) constitute a valuable source of anthocyanins, which are used as natural red, blue and purple food colourants. Anthocyanins phenolic compounds specialised metabolites, accumulation often requires elicitors, act molecular signals in plant stress responses. In the present study, ethephon, an ethylene-generating compound was explored enhancer anthocyanin contents during growth 'Deep Purple' black carrots. The effects ethephon on...
Growth retardation is an important breeding aim and essential part of horticultural plant production. Here, the potential transferring Arabidopsis short internode (shi) mutant phenotype was explored by expressing AtSHI gene in popular ornamental Kalanchoë. A 35S-AtSHI construct produced transferred into eight genetically different cultivars Kalanchoë Agrobacterium tumefaciens. The resulting transgenic plants showed dwarfing phenotypes like reduced height diameter, also more compact...
Reduced growth habit is a desirable trait for ornamental potted plants and can successfully be obtained through Rhizobium rhizogenes transformation in stable heritable manner. Additionally, it also by with Agrobacterium tumefaciens harboring specific genes from R. . The bacterial T-DNA harbors four root oncogenic loci ( rol ) 14 less known open reading frames (ORFs). genes, i.e., A, B, C, D, are conceived as the common denominator compact phenotype other characterized ORFs seem auxiliary but...
Functional investigation of individual Rhizobium rhizogenes oncogene contributes to a deeper understanding the mechanisms underlying R. rhizogenes-plant transformation, which holds potential enhancing plants' abiotic stress resistance. The root oncogenic locus (rol) B gene, key rhizogenes, was reported participate in resistance transformed plants. Yet, remain largely elusive. This study investigated Arabidopsis overexpressing A4-rolB (rolB-OX) for phenotypic modifications and short-term...
Euphorbia pulcherrima, poinsettia, is a non-food and non-feed vegetatively propagated ornamental plant. Appropriate plant height one of the most important traits in poinsettia production commonly achieved by application chemical growth retardants. To produce compact plants with desirable reduce utilization retardants, Arabidopsis SHORT INTERNODE (AtSHI) gene controlled cauliflower mosaic virus 35S promoter was introduced into Agrobacterium-mediated transformation. Three independent...
Betanins have become excellent replacers for artificial red-purple food colourants. Red beet (Beta vulgaris L. spp. vulgaris) known as beetroot, is a rich source of betalains, which major forms are betanin (red to purple) and vulgaxanthin (yellow). Betalains phenolic compounds secondary metabolites, accumulation often triggered by elicitors during plant stress responses. In the present study, pre-harvest applications ethephon (an ethylene-releasing compound) postharvest UV-B radiation were...
Medicinal cannabis (Cannabis sativa L.) is a growing agro-industrial sector with the end product required to be free of pesticides. C. covered by specialized hairs called trichomes, namely, two types non-glandular and three glandular trichomes. Despite great importance biological pest control in medicinal little known about impact trichomes on natural enemies mobility their interaction prey. In current study, employing video recording set-up, we determined Aphidoletes aphidimyza Chrysoperla...
