Physiological, metabolic and hormonal responses of two Pinus spp. with contrasting susceptibility to brown-spot needle blight disease
Oxford University Press (2024-01-09)Needle blights are serious fungal diseases affecting European natural and planted pine forests. Brown-spot needle blight (BSNB) disease, caused by the fungus Lecanosticta acicola, causes canopy defoliation and severe ... -
Plant metabolic response to stress in an arid ecosystem is mediated by the presence of neighbors
Wiley (2024-01-24)Plant neighbors in arid environments can ameliorate abiotic stress by reducing insolation, but they also attract herbivores and pathogens, especially when neighbors are close relatives that share similar antagonists. Plants' ... -
Plant responses to climate change: metabolic changes under combined abiotic stresses
Oxford University Press (2022-02-22)Climate change is predicted to increase the frequency and intensity of abiotic stress combinations that negatively impact plants and pose a serious threat to crop yield and food supply. Plants respond to episodes of stress ... -
Proline accumulation and antioxidant response are crucial for citrus tolerance to UV-B light-induced stress
Wiley (2024-04-03)Plants face a wide range of biotic and abiotic stress conditions, which are further intensified by climate change. Among these stressors, increased irradiation in terms of intensity and wavelength range can lead to detrimental ... -
Putrescine: A Key Metabolite Involved in Plant Development, Tolerance and Resistance Responses to Stress
MDPI (2022-03-10)Putrescine (Put) is the starting point of the polyamines (PAs) pathway and the most common PA in higher plants. It is synthesized by two main pathways (from ornithine and arginine), but recently a third pathway from ... -
PYL8 ABA receptors of Phoenix dactylifera play a crucial role in response to abiotic stress and are stabilized by ABA
Oxford University Press (2020-10-16)The identification of those prevalent abscisic acid (ABA) receptors and molecular mechanisms that trigger drought adaptation in crops well adapted to harsh conditions such as date palm (Phoenix dactylifera, Pd) sheds light ... -
Reduction of heat stress pressure and activation of photosystem II repairing system are crucial for citrus tolerance to multiple abiotic stress combination
(2022-10-30)Drought, heat and high irradiance are abiotic stresses that negatively affect plant development and reduce crop productivity. The confluence of these three factors is common in nature, causing extreme situations for plants ... -
Regulation of mycorrhizal colonization under stress in tomato depends on symbiotic efficiency
Elsevier (2023-08-21)The mutualistic symbiosis between plants and arbuscular mycorrhizal (AM) fungi is based on a balanced nutrient exchange between both partners, with the plant achieving improved nutrition and stress tolerance. The symbiosis ... -
Resistance Induction in Olive Tree (Olea europaea) Against Verticillium Wilt by Two Beneficial Microorganisms and a Copper Phosphite Fertilizer
(2022)Enhancement of the natural defenses of a plant by beneficial microorganisms, i.e., endophytic bacteria and fungi or fertilizers such as copper phosphonates, could result in a potential alternative strategy against verticillium ... -
ROS and redox regulation of cell-to-cell and systemic signaling in plants during stress
Elsevier (2022)Stress results in the enhanced accumulation of reactive oxygen species (ROS) in plants, altering the redox state of cells and triggering the activation of multiple defense and acclimation mechanisms. In addition to activating ... -
ROS are universal cell-to-cell stress signals
Elsevier (2024-04-20)The interplay between reactive oxygen species (ROS) and the redox state of cells is deeply rooted in the biology of almost all organisms, regulating development, growth, and responses to the environment. Recent studies ... -
Small Signals Lead to Big Changes: The Potential of Peptide-Induced Resistance in Plants
MDPI (2023-02-16)The plant immunity system is being revisited more and more and new elements and roles are attributed to participating in the response to biotic stress. The new terminology is also applied in an attempt to identify different ... -
Solanum lycopersicum heme-binding protein 2 as a potent antimicrobial weapon against plant pathogens
Nature Research (2023)The rise in antibiotic-resistant bacteria caused by the excessive use of antibiotics has led to the urgent exploration of alternative antimicrobial solutions. Among these alternatives, antimicrobial proteins, and peptides ... -
Specific ABA-independent tomato transcriptome reprogramming under abiotic stress combination
Wiley (2024-01-29)Crops often have to face several abiotic stresses simultaneously, and under these conditions, the plant's response significantly differs from that observed under a single stress. However, up to the present, most of the ... -
Spider mite herbivory induces an ABA-driven stomatal defense
Oxford University Press (2024)Arthropod herbivory poses a serious threat to crop yield, prompting plants to employ intricate defense mechanisms against pest feeding. The generalist pest 2-spotted spider mite (Tetranychus urticae) inflicts rapid damage ... -
Sustainable cultivation of melon landraces: Effects of grafting on the accumulation of flavor-related compounds
(2024)Melon landraces are highly appreciated by consumers who pay price premiums to compensate for lower yields, enabling on-farm conservation. However, they are highly susceptible to soilborne diseases. This study analyses the ... -
Systemic analysis of metabolome reconfiguration in Arabidopsis after abiotic stressors uncovers metabolites that modulate defense against pathogens
Cell Press, Elsevier (2023-07-04)Understanding plant immune responses is complex because of the high interdependence among biological processes in homeostatic networks. Hence, the integration of environmental cues causes network rewiring that interferes ... -
