The aim of this study was to examine the effects of ABA deficiency on tomato leaf response under severe drought stress. Therefore, ABA-mutant (flacca) and wild type (Ailsa Craig) were selected for research and in the stage of second flower truss anthesis plants were exposed to severe water deficit. The effects of severe drought on wild-type leaves and flacca mutant showed that, as a result of reduced ABA concentrations, flacca plants were exposed to a higher degree of stress than wild-type leaves, which had a negative impact on the examined physiological and biochemical parameters. Severe drought caused stomatal closure, decreased water potential, specific leaf area, and chlorophyll concentrations in the leaves in both genotypes, but this was more pronounced in the mutant. Wild-type plants have accumulated more vitamin C and ABA and have a higher total antio...

Here their effects on potato yield (Y) and water use efficiency (WUE) in the field grown potato was presented. PRDI and PRD plants were irrigated by 70% water of full irrigation (FI) during almost all season although in the last 3 weeks the amount of water in RDI and PRD was reduced to 50%. At harvest, the effects of RDI, PRD and FI on total (Y) marketable yield (MY) and WUE was measured. These ...
The effect of different irrigation regimes and the application of kaolin on stomatal conductance ... more The effect of different irrigation regimes and the application of kaolin on stomatal conductance and leaf water potential of pepper (Capsicum annuum L.) and tomato (Lycopersicon esculentum Mill.), is discussed in the paper.The experiment was set up by a completely randomized block system with three replications. The peppers were observed in three, and tomatoes in two treatments of irrigation regimes. The kaolin treatments of both crops were: a) control without kaolin (C) and 5% kaolin suspension (K).The results of these studies show that the application of deficit irrigation treatments and kaolin treatment have no statistically significant effect on stomatal conductance and leaf water potential of pepper and tomato plants

Results confirmed differences in the expression of the investigated genes under the investigated treatments, during treatment duration as well as between investigated WT and flacca plants. The most significant differences between WT and flacca were found under PRD treatment. The similar expression pattern of all genes in the WT plants could indicate synergistic signaling pathways for ABA and ethylene. In flacca, reduced NCED and significant EIL1 expression might reflect the increase in ethylene production, which could influence the ABA signaling and production that occurred under PRD. Drought also induced an increase in ABA content that is most expressed in flacca under RDI.

The fruit growth analysis showed that the slower fruit growth rate and development resulted in smaller flacca fruits in comparison to the wild-type fruits. The comparison of the temporal dynamics of cell wall peroxidase activity and ABA content in our experiment indicated an opposite relationship during fruit development. Proteomic analysis and the down-regulation of most proteins from carbon and amino acid metabolism, the translation and processing of proteins, energy metabolism and cell wall-related metabolism in the flacca fruits compared to the wild type, indicated reduced metabolic flux which reflected...

The seismic data sample the oceanic lithosphere extending between the Romanche Transform Fault to the Charcot Fracture Zone. Refraction data were collected during the ILAB-SPARC experiment. The provided refraction data were recorded on 25 Ocean Bottom Seismometer (OBS data) instruments (from 25 to 50) and span source-receiver offsets from ~-100 km to 100 km. Reflection (multichannel seismic - MCS data), we provide are sorted as CMP gathers that were used to produce seismic sections for imaging layer 2A. The data were collected during two experiments, using different survey geometries: 1) ILAB_SPARC_CMP.segy (in 5 parts): collected during ILAB_SPARC experiment in 2018, sample the region south of the Chain Fracture Zone. The maximum source-receiver offset is ~6 km. Note that the provided data were int...
