Differential Antioxidant Response to Supplemental UV-B Irradiation and Sunlight in Three Basil Varieties.

Three basil plant varieties ( var. Genovese, × , and var. ) were grown under moderate light (about 300 µmol photons m s) in a glasshouse or growth chamber and then either transferred to an open field (average daily dose: 29.

In Silico Characterisation of the Late Embryogenesis Abundant (LEA) Protein Families and Their Role in Desiccation Tolerance in Panc.

Panc. is an ancient resurrection plant able to survive a long desiccation period and recover metabolic functions upon watering. The accumulation of protective late embryogenesis abundant proteins (LEAPs) is a desiccation tolerance hallmark.

Differential Response of Two Tomato Genotypes, Wild Type cv. Ailsa Craig and Its ABA-Deficient Mutant to Short-Termed Drought Cycles.

Two tomato genotypes with constitutively different ABA level, mutant and wild type of Ailsa Craig cv. (WT), were subjected to three repeated drought cycles, with the aim to reveal the role of the abscisic acid (ABA) threshold in developing drought tolerance. Differential responses to drought of two genotypes were obtained: more pronounced stomatal closure, ABA biosynthesis and proline accumulation in WT compared to the mutant were compensated by dry weight accumulation accompanied by transient redox disbalance in .

First report of Pectobacterium versatile causing blackleg of potato in Serbia.

Potato blackleg is frequently observed on the production fields in the Bačka region of Vojvodina province, which is one of the largest potato-growing areas in Serbia. This disease usually occurs during June and July. In July 2020, blackleg symptoms in the form of stem necrotic lesions, vascular discoloration, hollow stems, and wilting of whole plants were noted on potato cultivar VR808 on a field 28 ha in size located in Maglić village (GPS coordinates 45.

Leaf Soluble Sugars and Free Amino Acids as Important Components of Abscisic Acid-Mediated Drought Response in Tomato.

Water deficit has a global impact on plant growth and crop yield. Climate changes are going to increase the intensity, duration and frequency of severe droughts, particularly in southern and south-eastern Europe, elevating the water scarcity issues. We aimed to assess the contribution of endogenous abscisic acid (ABA) in the protective mechanisms against water deficit, including stomatal conductance, relative water potential and the accumulation of osmoprotectants, as well as on growth parameters.

Antioxidative response in variegated Pelargonium zonale leaves and generation of extracellular HO in (peri)vascular tissue induced by sunlight and paraquat.

In this study we exposed variegated leaves of Pelargonium zonale to strong sunlight (>1100μmolms of photosynthetically active radiation) with and without paraquat (Pq), with the aim to elucidate the mechanisms of HO regulation in green and white tissues with respect to the photosynthetically-dependent generation of reactive oxygen species (ROS). Sunlight induced marked accumulation of HO in the apoplast of vascular and (peri)vascular tissues only in green sectors. This effect was enhanced by the addition of Pq.
