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 ...
Plant adaptations to the combination of drought and hightemperatures
Under ﬁeld conditions crops are routinely subjected to a number of differentabiotic stress factors simultaneously. Recent studies revealed that the responseof plants to a combination of different abiotic stresses is unique ...
Regulation of citrus responses to the combined actionof drought and high temperatures depends on the severityof water deprivation
Plants grown in natural environment are regularly subjected to different combinations of abiotic stresses. Recent studies revealed that citrus plants subjected to a combination of severe drought and high temperatures ...
Modulation of Antioxidant Defense System Is Associated with Combined Drought and Heat Stress Tolerance in Citrus
(Frontiers Media, 2017-06)
Drought and high temperatures are two major abiotic stress factors that often occur simultaneously in nature, affecting negatively crop performance and yield. Moreover, these environmental challenges induce oxidative ...
Polyamine oxidase 5 loss-of-function mutations in Arabidopsisthaliana trigger metabolic and transcriptional reprogrammingand promote salt stress tolerance
The family of polyamine oxidases (PAO) in Arabidopsis(AtPAO1–5) mediates polyamine (PA) back-conversion,which reverses the PA biosynthetic pathway from spermineand its structural isomer thermospermine (tSpm) intospermidine ...
Attenuated accumulation of jasmonates modifies stomatal responses to water deficit
(Oxford University PressSociety for Experimental Biology, 2018-02)
To determine whether drought-induced root jasmonate [jasmonic acid (JA) and jasmonic acid-isoleucine (JA-Ile)] accumulation affected shoot responses to drying soil, near-isogenic wild-type (WT) tomato (Solanum lycopersicum ...
Metabolomics of Disease Resistance in Crops
(Horizon Scientific Press, 2016)
Plants are continuously exposed to the attack of invasive microorganisms, such as fungi or bacteria, and also viruses. To fight these attackers, plants develop different metabolic and genetic responses whose final ...
Protocol for Increasing Carotenoid Levels in the Roots of Citrus Plants
(Bio-protocol LLC, 2016)
Carotenoids in plants play several key functions such as acting as light-harvesters, antioxidants (Lado et al., 2016) or being precursors of strigolactones, abscisic acid, volatiles and other signaling compounds (Arbona ...
Leaf dehydration is needed to induce abscisic acid accumulation in roots of citrus plants
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. ...
Depletion of abscisic acid levels in roots of flooded Carrizo citrange (Poncirus trifoliata L. Raf. x Citrus sinensis L. Osb.) plants is a stress-specific response associated to the differential expression of PYL/PYR/RCAR receptors
(Springer Verlag, 2017)
Soil flooding reduces root abscisic acid (ABA) levels in citrus, conversely to what happens under drought. Despite this reduction, microarray analyses suggested the existence of a residual ABA signaling in roots of flooded ...
