Loss-of-function of NITROGEN LIMITATION ADAPTATION confers disease resistance in Arabidopsis by modulating hormone signaling and camalexin content
(Elsevier ScienceDirect, 2022-07-15)
Phosphorus is an important macronutrient required for plant growth and development. It is absorbed by the roots in the form of inorganic phosphate (Pi). Under Pi limiting conditions, plants activate the Phosphate Starvation ...
Inheritance of Secondary Metabolites and Gene Expression Related to Tomato Fruit Quality
(MDPI, 2022-05-31)
Flavour and nutritional quality are important goals for tomato breeders. This study aimed to shed light upon transgressive behaviors for fruit metabolic content. We studied the metabolic contents of 44 volatile organic ...
Soil moisture heterogeneity regulates water use in Populus nigra L. by altering root and xylem sap phytohormone concentrations
(Oxford University Press, 2020)
Soil moisture heterogeneity in the root zone is common both during the establishment of tree seedlings and in
experiments aiming to impose semi-constant soil moisture deficits, but its effects on regulating plant water ...
Tolerance of citrus plants to the combination of high temperatures and drought is associated to the increase in transpiration modulated by a reduction in abscisic acid levels
(BioMed Central, 2016)
Background: In natural environments, several adverse environmental conditions occur simultaneously constituting
a unique stress factor. In this work, physiological parameters and the hormonal regulation of Carrizo citrange ...
Involvement of the def-1 Mutation in the Response of Tomato Plants to Arbuscular Mycorrhizal Symbiosis Under Well-Watered and Drought Conditions
(Oxford University Press, 2018)
Jasmonic acid (JA) and arbuscular mycorrhizal (AM) symbioses
are known to protect plants against abiotic and biotic
stresses, but are also involved in the regulation of root hydraulic
conductance (L). The objective of ...
ABA accumulation in water-stressed Citrus roots does not rely on carotenoid content in this organ
(Elsevier, 2016)
Sustained abscisic acid (ABA) accumulation in dehydrated citrus roots depends on the transport from aerial organs. Under this condition, the role of the β,β-carotenoids (ABA precursors) to the de novo synthesis of ABA in ...
Metabolomic profiling of the halophyte Prosopis strombulifera shows sodium salt- specific response
(Elsevier, 2016)
Primary and secondary metabolite profiles were analyzed in roots and leaves of the halophytic shrub
Prosopis strombulifera in response to control plants (no salt added in the growing media) and to lowering
the osmotic ...
Leaf dehydration is needed to induce abscisic acid accumulation in roots of citrus plants
(Elsevier, 2017-05-09)
The root system is the main organ involved in the water uptake and it is assumed that it perceives soil dehydration, triggering water stress responses at the entire plant level, including abscisic acid (ABA) accumulation. ...
Rapid and reproducible determination of active gibberellins in citrus tissues by UPLC/ESI-MS/MS
(Elsevier, 2015)
Phytohormone determination is crucial to explain the physiological mechanisms during growth and
development. Therefore, rapid and precise methods are needed to achieve reproducible determination of
phytohormones. Among ...
Ectopic expression of a stress-inducible glycosyltransferase from saffron enhances salt and oxidative stress tolerance in Arabidopsis while alters anchor root formation
(Elsevier, 2015)
Glycosyltransferases play diverse roles in cellular metabolism by modifying the activities of regulatory
metabolites. Three stress-regulated UDP-glucosyltransferase-encoding genes have been isolated fromthe
stigmas of ...
