Growth of Arabidopsis thaliana seedlings under water deficit studied by control of water potential in nutrient-agar media.
Csak regisztrált felhasználók fordíthatnak cikkeket
Belépés Regisztrálás
We have characterized the growth responses of Arabidopsis thaliana seedlings to water deficit. To manipulate the water potential, we developed a method whereby the nutrient-agar medium could be supplemented with polyethylene glycol (PEG 8000); PEG was introduced into gelled media by diffusion, which
Abscisic Acid Receptors and Coreceptors Modulate Plant Water Use Efficiency and Water Productivity.

Belépés Regisztrálás
Improving the water use efficiency (WUE) of crop plants without trade-offs in growth and yield is considered a utopic goal. However, recent studies on model plants show that partial restriction of transpiration can occur without a reduction in CO2 uptake and photosynthesis. In this study,
A T-DNA insertion mutant of AtHMA1 gene encoding a Cu transporting ATPase in Arabidopsis thaliana has a defect in the water-water cycle of photosynthesis.

The water-water cycle is the electron flow through scavenging enzymes for the reactive species of oxygen in chloroplasts, and is proposed to play a role in alternative electron sink in photosynthesis. Here we showed that the water-water cycle is impaired in the T-DNA insertion mutant of AtHMA1 gene
Hydrotropism: how roots search for water.
Csak regisztrált felhasználók fordíthatnak cikkeket
Belépés Regisztrálás
Fresh water is an increasingly scarce resource for agriculture. Plant roots mediate water uptake from the soil and have developed a number of adaptive traits such as hydrotropism to aid water foraging. Hydrotropism modifies root growth to respond to a water potential gradient in soil and grow
Glycine betaine involvement in freezing tolerance and water stress in Arabidopsis thaliana.

Levels of endogenous glycine betaine in the leaves were measured in response to cold acclimation, water stress and exogenous ABA application in Arabidopsis thaliana. The endogenous glycine betaine level in the leaves increased sharply during cold acclimation treatment as plants gained freezing
Abscisic Acid Elicits the Water-Stress Response in Root Hairs of Arabidopsis thaliana.

Belépés Regisztrálás
Water stress has been shown to cause root hairs to become short and bulbous. Because abscisic acid (ABA) mediates a variety of water-stress responses, we investigated the response of Arabidopsis thaliana root hairs to ABA. When wild-type root hairs were treated with ABA, they exhibited the
Effects of intentionally treated water and seeds on the growth of Arabidopsis thaliana

Objective: . A previously reported experiment indicated that Arabidopsis thaliana seeds with cryptochrome mutation His-CRY2 showed more robust photomorphogenic growth when hydrated with intentionally treated water as compared to untreated water. The present study
Divergent low water potential response in Arabidopsis thaliana accessions Landsberg erecta and Shahdara.
Csak regisztrált felhasználók fordíthatnak cikkeket
Belépés Regisztrálás
The Arabidopsis thaliana accession Shahdara (Sha) differs from Landsberg erecta (Ler) and other accessions in its responses to drought and low water potential including lower levels of proline accumulation. However, Sha maintained greater seedling root elongation at low water potential and a higher
Water stress and aphid feeding differentially influence metabolite composition in Arabidopsis thaliana (L.).
Csak regisztrált felhasználók fordíthatnak cikkeket
Belépés Regisztrálás
Little is known about how drought stress influences plant secondary metabolite accumulation and how this affects plant defense against different aphids. We therefore cultivated Arabidopsis thaliana (L.) plants under well-watered, drought, and water-logged conditions. Two aphid species were selected
Peptide transporter2 (PTR2) enhances water uptake during early seed germination in Arabidopsis thaliana.
Csak regisztrált felhasználók fordíthatnak cikkeket
Belépés Regisztrálás
PTR2 in Arabidopsis thaliana is negatively regulated by ABI4 and plays a key role in water uptake by seeds, ensuring that imbibed seeds proceed to germination. Peptide transporters (PTRs) transport nitrogen-containing substrates in a proton-dependent manner. Among the six PTRs in Arabidopsis
Comparative Analysis of Phosphoproteome Remodeling After Short Term Water Stress and ABA Treatments versus Longer Term Water Stress Acclimation.
Csak regisztrált felhasználók fordíthatnak cikkeket
Belépés Regisztrálás
Several studies have used short term dehydration, osmotic stress or Abscisic Acid (ABA) treatments to identify the initial protein phosphorylation-dephosphorylation responses to drought and low water potential or ABA treatments. However, longer term drought acclimation leads to altered expression of
Leaf water dynamics of Arabidopsis thaliana monitored in-vivo using terahertz time-domain spectroscopy.

The declining water availability for agriculture is becoming problematic for many countries. Therefore the study of plants under water restriction is acquiring extraordinary importance. Botanists currently follow the dehydration of plants comparing the fresh and dry weight of excised organs, or
Overexpression of Chickpea Defensin Gene Confers Tolerance to Water-Deficit Stress in Arabidopsis thaliana.

Plant defensins are mainly known for their antifungal activity. However, limited information is available regarding their function in abiotic stresses. In this study, a defensin gene, Ca-AFP, from Cicer arietinum, commonly known as chickpea, was cloned and transformed in Arabidopsis

Interest on the environmental impacts of engineered nanomaterials has rapidly increased over the past years because it is expected that these materials will eventually be released into the environment. The present work investigates the potential root uptake of water-dispersible CdSe/ZnS quantum dots
