Nondestructive assessment of water content and stress in plants is an important component the rational use crop irrigation management precision agriculture. Spectral measurements light reflectance UV/VIS/NIR region (350–1075 nm) from individual leaves were acquired under a rapid dehydration protocol for validation remote sensing soybean plants. Four gravimetrical approaches leaf used: relative (RWC), foliar as percent total fresh mass (FWCt), dry (FWCd), equivalent thickness (EWT). Leaf...
We assessed the photosynthetic responses of eight wheat varieties in conditions a simulated heat wave transparent plastic tunnel for one week. found that high temperatures (up to 38 °C at midday and above 20 night) had negative effect on functions plants provided differentiation genotypes through sensitivity heat. Measurements gas exchange showed led 40% decrease activity average comparison control, with an unequal recovery individual after release from stress. Our results indicate ability...
The impact of severe drought stress (13% soil moisture) on the physiological responses, metabolic profile, and pathogenesis-related (PR) proteins in wheat above- below-ground biomass after 20 days treatment was studied. Drought depleted growth, assimilation pigments, majority free amino acids shoots (but proline increased considerably, +160%). On contrary, root growth parameters were elevated, did not decrease, indicating investment metabolites into roots under water deficiency. Mineral...
To assess the reliability and sensitivity of non-invasive optical methods to detect early effects water deficit in field, we analyzed time-series measurements obtained a dry season representative collection wheat genotypes grown small-plot field trials, non-irrigated irrigated variants. Despite progressive significant yield loss, indicated very minor changes chlorophyll content or canopy cover. This corresponded well insignificant differences spectral reflectance normalized difference...
Plant viruses threaten agricultural production by reducing the yield, quality, and economical benefits. Tomato mosaic virus (ToMV) from genus Tobamovirus causes serious losses in quantity quality of tomato production. The management plant protection is very difficult, mainly due to vector-less transmission ToMV. Resistant breeding generally has low effectiveness. most practical approach use a rapid diagnostic assay virus’ presence before symptoms occur plants, followed eradication...
The in vitro cell cultures derived from the grapevine (Vitis vinifera L.) have been used for production of stilbenes treated with different biotic and abiotic elicitors. red-grape cultivar Váh has elicited by natural cellulose Trichoderma viride, wall homogenate Fusarium oxysporum synthetic jasmonates. sodium-orthovanadate, known as an inhibitor hypersensitive necrotic response plant cells able to enhance release secondary metabolite into cultivation medium, was elicitor. Growth content...
Plant genomes are unique in an intriguing feature: the range of their size variation is unprecedented among living organisms. Although polyploidization contributes to this variability, transposable elements (TEs) seem play pivotal role. TEs, often considered intragenomic parasites, not only affect genome host, but also interact with other genes, disrupting and creating new functions regulatory networks. Coevolution plant TEs has led tight regulation TE activity, growing evidence suggests...
In recent years, high throughput sequencing (HTS) has brought new possibilities to the study of diversity and complexity plant viromes. Mixed infection a single with several viruses is frequently observed in such studies. We analyzed virome 10 tomato sweet pepper samples from Slovakia, all showing presence potato virus Y (PVY) infection. Most datasets allow determination nearly complete sequence single-variant PVY genome, belonging one recombinant strains (N-Wi, NTNa, or NTNb). However,...
Phaseolus vulgaris alphaendornavirus-1 (PvEV-1, family Endornaviridae ) was identified by ribodepleted total RNA high-throughput sequencing in the virome of two bean plants ( Phaseouls L.) grown a garden western Slovakia. Two nearly complete PvEV-1 genomes (ca. 14.06 kb, named PV1 and PV2) were assembled, showing 99.9% nucleotide identity, while their identity with reference genome (NC_039217) reached 98.4%. primer pairs spanning viral helicase encoding region sequence upstream RNA-dependent...
Toxic metal pollutants such as cadmium disrupt all stages of plant development. Flax (Linum usitatissimum L.) has demonstrated the ability to tolerate and accumulate high amounts cadmium, making it suitable for phytoremediation. Within-species variability tolerance uptake needs be examined in controled conditions assess multiple beneficial, or even required traits use phytoremediation programs. In this study, 31 flax cultivars were screened their germinate grow presence a sublethal...
A remarkable portion of crop genetic diversity is represented by landraces and obsolete cultivars, that have not yet been integrated into the collections resources in genebanks. Fortunately, they are still maintained small farmers rural areas. Their acquisition an important goal for collecting expeditions, followed evaluation their background. Molecular markers powerful tools to evaluate effectiveness new variants. This approach was used common bean landraces, were collected through...
Euonymus species from the Celastraceae family are considered as a source of unusual genes modifying oil content and fatty acid composition vegetable oils. Due to possession encoding enzyme diacylglycerol acetyltransferase (DAcT), plants can synthesize accumulate acetylated triacyglycerols. The gene europaeus (EeDAcT) DAcT was identified, isolated, characterized, modified for cloning genetic transformation plants. This has unique nucleotide sequence amino composition, different orthologous...
Two projects: Conservation and use of genetic resources non-traditional crops, related wild species for food agriculture; Characterization evaluation diversity wheat their relatives utilising in breeding involve research into rare endangered the territory Slovakia. In Slovakia, many threatened plant occur. this group plants, Aegilops cylindrica Host Arctous alpina (L.) Nied are also listed. They registered Red Data Book To locate occurrences these species, we have used a GPS system. article,...
