Drought, the most prominent threat to agricultural production worldwide, accelerates leaf senescence, leading a decrease in canopy size, loss photosynthesis and reduced yields. On basis of assumption that senescence is type cell death program could be inappropriately activated during drought, we hypothesized it may possible enhance drought tolerance by delaying drought-induced senescence. We generated transgenic plants expressing an isopentenyltransferase gene driven stress-...
Many studies have described the response mechanisms of plants to salinity and heat applied individually; however, under field conditions some abiotic stresses often occur simultaneously. Recent revealed that a combination two different is specific cannot be deduced from individually. Here, we report on tomato salt stress. Interestingly, in contrast expected negative effect stress plant growth, our results show provides significant level protection effects salinity. We observed included...
Abiotic stresses such as drought, heat or salinity are a major cause of yield loss worldwide. Recent studies revealed that the acclimation plants to combination different environmental is unique and cannot be directly deduced from studying response each applied individually. Here we report on Arabidopsis thaliana salt stress using transcriptome analysis, physiological measurements mutants deficient in abscisic acid, salicylic jasmonic acid ethylene signaling. were found more susceptible...
Abiotic stresses such as drought, heat or salinity are major causes of yield loss worldwide. Recent studies have revealed that the acclimation plants to a combination different environmental is unique and therefore cannot be directly deduced from studying response each applied individually. The efficient detoxification reactive oxygen species (ROS) thought play key role in enhancing tolerance abiotic stresses. Here, we report on melatonin protection photosynthetic apparatus through increase...
We investigated the effects of P(SARK)IPT (for Senescence-Associated Receptor KinaseIsopentenyltransferase) expression and cytokinin production on several aspects photosynthesis in transgenic tobacco (Nicotiana tabacum cv SR1) plants grown under optimal or restricted (30% optimal) watering regimes. There were no significant differences stomatal conductance between leaves from wild-type P(SARK)-IPT watering. On other hand, there was a reduction maximum rate electron transport as well use...
Efficient detoxification of reactive oxygen species (ROS) is thought to play a key role in enhancing the tolerance plants abiotic stresses. Although multiple pathways, enzymes and antioxidants are present plants, their exact roles during different stress responses remain unclear. Here we report on characterization antioxidant mechanisms tomato subjected heat stress, salinity or combination both All treatments applied induced an increase oxidative with treatment being most aggressive,...
In natural environments, several adverse environmental conditions occur simultaneously constituting a unique stress factor. this work, physiological parameters and the hormonal regulation of Carrizo citrange Cleopatra mandarin, two citrus genotypes, in response to combined action high temperatures water deprivation were studied. The objective was characterize particular responses combination. Experiments indicated that is more tolerant combination than mandarin. Furthermore, an experimental...
Plant growth and development requires efficient acquisition of essential elements. Potassium (K(+)) is an important macronutrient present in the soil solution at a wide range concentrations. Regulation K(+) uptake systems roots to secure supply. It has been shown Arabidopsis (Arabidopsis thaliana) that when external concentration very low (<10 µm), nutrition depends exclusively on high-affinity transporter5 (HAK5). Low-K(+)-induced transcriptional activation gene encoding HAK5 previously...
Abstract The adverse effects of mounting environmental challenges, including extreme temperatures, threaten the global food supply due to their impact on plant growth and productivity. Temperature extremes disrupt genetics, leading significant issues eventually damaging phenotypes. Plants have developed complex signaling networks respond tolerate temperature stimuli, genetic, physiological, biochemical, molecular adaptations. In recent decades, omics tools other strategies rapidly advanced,...
To identify genes associated with the cytokinin-induced enhanced drought tolerance, we analyzed transcriptome of wild-type and transgenic tobacco (Nicotiana tabacum 'SR1') plants expressing PSARK::IPT (for senescence-associated receptor kinase::isopentenyltransferase) grown under well-watered prolonged water deficit conditions using tomato GeneChip. During deficit, expression encoding components carotenoid pathway leading to ABA biosynthesis was in plants, but repressed plants. On other...
Grapevine red blotch-associated virus (GRBaV) is a major threat to the wine industry in USA. GRBaV infections (aka blotch disease) compromise crop yield and berry chemical composition, affecting flavor aroma properties of must wine. In this study, we combined genome-wide transcriptional profiling with targeted metabolite analyses biochemical assays characterize impact disease on red-skinned ripening metabolism. Using naturally infected berries collected from two vineyards, were able identify...
Noble rot results from exceptional infections of ripe grape (Vitis vinifera) berries by Botrytis cinerea. Unlike bunch rot, noble promotes favorable changes in and the accumulation secondary metabolites that enhance wine composition. rot-infected cv Sémillon, a white-skinned variety, were collected over 3 years commercial vineyard at same time fruit harvested for botrytized production. Using an integrated transcriptomics metabolomics approach, we demonstrate alters metabolism Sémillon...
SUMMARY Crops often have to face several abiotic stresses simultaneously, and under these conditions, the plant's response significantly differs from that observed a single stress. However, up present, most of molecular markers identified for increasing plant stress tolerance been characterized stresses, which explains unexpected results found when plants are tested real field conditions. One important regulator responses is abscisic acid (ABA). The ABA signaling system engages many...
HAK/KUP/KT K(+) transporters have been widely associated with transport across membranes in bacteria, fungi, and plants. Indeed some members of the plant family contribute to root uptake, notably at low external concentrations. Besides such role acquisition, several studies carried out Arabidopsis shown that other are also involved developmental processes. With publication new genomes, a growing interest on species than has become evident. In order understand diversity these we discuss...
Potassium (K(+)) is an essential macronutrient required for plant growth, development and high yield production of crops. Members group I the KT/HAK/KUP family transporters, such as HAK5, are key components K(+) acquisition by roots at low external concentrations. Certain abiotic stress conditions salinity or Cs(+)-polluted soils may jeopardize nutrition because HAK5-mediated transport inhibited Na(+) Cs(+). Here, screening in yeast a randomly-mutated collection AtHAK5 new mutation sequence...
The high-affinity K(+) transporter HAK5 is a key system for root uptake and, under very low external K(+), the only one capable of supplying to plant. Functional HAK5-mediated should be tightly regulated plant adaptation different environmental conditions. Thus, it has been described that gene encoding transcriptionally regulated, being highly induced limitation. Here we show conditions, such as lack NO(3)(-) or P, hyperpolarization plasma membrane cells, induce transcription. However,...
