NF-Y (NUCLEAR FACTOR-Y), a heterotrimeric transcription factor, is composed of NF-YA, NF-YB, and NF-YC proteins in yeast, animal, and plant systems. In plants, each of the NF-YA/B/C subunit forms a multi-member family. NF-Ys are key regulators with important roles in many physiological processes, such as drought tolerance, flowering time, and seed(More)
Agricultural production continues to be constrained by a number of biotic and abiotic factors that can reduce crop yield quantity and quality. Potassium (K) is an essential nutrient that affects most of the biochemical and physiological processes that influence plant growth and metabolism. It also contributes to the survival of plants exposed to various(More)
Salinity is a major abiotic stress factor limiting plant growth and productivity. One possible method to enhance plant salt-resistance is to compartmentalize sodium ions away from the cytosol. In the present work, a vacuolar Na+/H+ antiporter gene AtNHX1 from Arabidopsis thaliana, was transferred into Populus × euramericana ‘Neva’ by Agrobacterium(More)
Two novel DREB (dehydration-responsive element-binding protein) genes, designated as CiDREB1A and CiDREB1B, were cloned from chicory (Cichorium intybus). Both of these genes contained a conserved EREBP/AP2 domain and were classified into the A-1 subgroup of the DREB subfamily based on phylogenetic analysis. Quantitative real-time PCR analysis revealed that(More)
Responses of Ulva prolifera and Ulva linza to Cd(2+) stress were studied. We found that the relative growth rate (RGR), Fv/Fm, and actual photochemical efficiency of PSII (Yield) of two Ulvaspecies were decreased under Cd(2+) treatments, and these reductions were greater in U. prolifera than in U. linza. U. prolifera accumulated more cadmium than U. linza(More)
This study examined brassinosteroids-induced enhancement of plant salt resistance of tomato. Pot experiment was conducted in the whole-life-cycle of cherry tomato. The effects of 24-epibrassinolide (EBL) foliar spraying on temporal and spatial distributions of ions and PAs in the whole-life-cycle of salt-stressed plants were studied. EBL could well relieve(More)
Melatonin (N-acetyl-5-methoxytryptamine) is a biological hormone involved in many important physiological processes in plants. To better understand the protective roles of melatonin in plants against salt stress, we determined the effects of exogenous melatonin (1 µM) on plant growth, photosynthesis, antioxidant enzyme activity and ion homeostasis in maize(More)
Superoxide dismutases (SODs) are critical antioxidant enzymes that protect organisms from reactive oxygen species (ROS) caused by adverse conditions, and have been widely found in the cytoplasm, chloroplasts, and mitochondria of eukaryotic and prokaryotic cells. Tomato (Solanum lycopersicum L.) is an important economic crop and is cultivated worldwide.(More)
