In this article, the effects of drought stress (DS) on gas exchange, chlorophyll (Chl) a fluorescence and Calvin cycle enzymes in Phaseolus vulgaris are evaluated. Three-week-old plants were exposed to DS by receiving only so much water every evening ensure 30% field capacity content overnight. After three days under these conditions, we observed that induced decline CO2 assimilation. Gas-exchange data showed closure stomata during did not lead concomitant calculated intercellular...
In the last decades, use of fungicides in agriculture for fungi diseases control has become crucial. Fungicide research produced a diverse range products with novel modes action. However, extensive these compounds system raises public concern because harmful potential such substances environment and human health. Moreover, phytotoxic effects some are already recognized but little is known about impact on photosynthetic apparatus. This paper presents comprehensive overview literature...
Trees necessarily experience changes in temperature, requiring efficient short-term strategies that become crucial environmental change adaptability. DNA methylation and histone posttranslational modifications have been shown to play a key role both epigenetic control plant functional status under stress by controlling the state of chromatin gene expression. Cork oak (Quercus suber L.) is stone Mediterranean region, growing at temperatures 45°C. This species was subjected cumulative...
Cadmium is a priority pollutant. Its mechanisms and effects within different plant organs remain unclear. Here, cyto-genotoxicity biomarkers were evaluated in roots leaves after Cd exposure (0, 1, 10, 50 μM) of the model crop Lactuca sativa L. (cv. "Reine de Mai"). Overall, superoxide dismutase (SOD) catalase (CAT) activities stimulated leaves, where accumulation was lower comparison to that roots. In roots, SOD peroxidase (POX, APX) stimulated. Moreover, both glutathione reductase (GR) not...
Eucalyptus plantations are among the most productive forest stands in Portugal and Spain, being mostly used for pulp production and, more recently, as an energy crop. However, region's Mediterranean climate, with characteristic severe summer drought, negatively affects eucalypt growth increases mortality. Although physiological response to water shortage is well characterized this species, evidence about plants' recovery ability remains scarce. In order assess biochemical of globulus during...
Olive leaves are an abundant by-product of olive oil production. leaf extracts (OLEs) rich in polyphenols, which can be used for health benefits. As polyphenols the main antioxidant molecules plants, plants typically increase their polyphenol content when exposed to drought stress. However, phenolic profile OLEs vary relation origin and variety plant material. In this work, from three different Italian cultivars (Giarraffa, Leccino, Maurino) both not stress were studied terms properties...
Given the economical importance of olive tree it is essential to study its responses stress agents such as excessive UV-B radiation, understand defense mechanisms and identify varieties that are able cope with it. In light analysis carried out in this study, we argue radiation represents a dangerous source for tree, especially current increasingly changing environmental conditions. Both considered (Giarraffa Olivastra Seggianese), although resistant strong treatment which they were exposed,...
