Background: Carrot is an important vegetable crop grown worldwide. The major economic problem in carrot cultivation is yellow disease caused by Bactericera trigonica, which induces biotic stress and has the greatest impact on crop productivity. Comprehensive studies on the mechanism of carrot defense response to biotic stress caused by B.

These parameters could serve as indicators of drought tolerance of , a popular horticultural plant worldwide that is very sensitive to drought. The experiment included four treatments: control, drought-stressed plants sprayed with distilled water, drought-stressed plants sprayed with 5 µM MeJA, and drought-stressed plants sprayed with 50 µM MeJA.

To cope with drought, plants have drought tolerance mechanisms at the physiological, biochemical, and molecular levels. In this study, the effects of foliar application of distilled water and methyl jasmonate (MeJA) (5 and 50 µM) on the physiological, biochemical, and molecular responses of during two drought regimes (15 and 5% soil water content, SWC) were investigated.

The aim of this work was to investigate the influence of sodium nitroprusside (SNP), a donor of nitric oxide (NO), on the physiological response of common centaury () shoots grown under stress conditions caused by sodium chloride (NaCl) in vitro. Centaury shoots were first grown on nutrient medium containing different SNP concentrations (50, 100 and 250 μM) during the pretreatment phase.

In this study, the effects of a water-soluble hyper-harmonized hydroxyl-modified fullerene (3HFWC) on cherry tomato seed germination, seedlings growth, physiological response and fruiting was evaluated. Changes in the photosynthetic pigments content, oxidative stress assessment, and aquaporin genes expression in cherry tomato plants were studied after during short- and long-term continuous exposure to 3HFWC nanosubstance (200 mg/L).

MicroRNAs have been shown to have a predictive potential for radiotoxicity. The goal of the study was to test if levels of miRNA in peripheral blood mononuclear cells of glioblastoma patients are associated with toxicity and to identify the peak time point for toxicity.

Abiotic stresses considerably affect production and distribution of phytohormones as the stress signal triggers. The homeostasis of plant hormones is controlled by their de novo synthesis and catabolism.
View Article and Find Full Text PDFAquaporins comprise a large group of transmembrane proteins responsible for water transport, which is crucial for plant survival under stress conditions. Despite the vital role of aquaporins, nothing is known about this protein family in a commercially important horticultural plant, which is sensitive to drought stress. In the present study, attention is given to the molecular characterization of aquaporins in and their expression during drought stress and recovery.

We investigated whether the foliar application of 2mM salicylic acid (SA) can protect potted plants from drought stress. The plants were divided into: watered plants, drought-stressed plants, watered plants treated with SA and drought-stressed plants treated with SA.

In this study, we investigated the effect of soaking bulbs in GA solution (1, 2, and 3 mg L) combined with low-temperature treatment (7 °C) on breaking the dormancy of in vitro bulbs.

Experiment design included three treatments: Control plants-grown under optimal watering (35%-37% of soil moisture content), drought-stressed plants-non-irrigated to reach 15% and 5% of soil moisture content and recovery plants-rehydrated for four days to reach optimal soil moisture content. Drought reduced fresh weight, total leaf area, as well as dry weight of shoots.

In nature, as well as in vitro, they become dormant and require low temperatures for further growth during the next vegetative period. In the present study, using 10 μM of gibberellic acid (GA), or gibberellin biosynthesis (GA) inhibitors-ancymidol (A) and paclobutrazol (P)-the dynamic changes in soluble sugars, fructose and glucose content, fresh weight and sprouting capacity were investigated.

In Serbia, temozolomide was introduced as adjuvant therapy in 2011. The aims of this study were to confirm the safety and efficacy on overall and progression-free survival of the Stupp protocol and evaluate the influence of prognostic factors in one of the largest series of patients with GBM treated over a 2-year period.
