Despite great interest, not only from the economic point of view but also in terms basic science, research on heat stress tolerance conifers remains scarce. To fill this gap, a time-course experiment using expected temperature increase was performed aiming to identify physiological and biochemical traits that allow characterization heat-induced thermotolerance recovery Pinus radiata D. Don plants. Several parameters were assessed during exposure after recovery, multiple...
Globally expected changes in environmental conditions, especially the increase of UV irradiation, necessitate extending our knowledge mechanisms mediating tree species adaptation to this stress. This is crucial for designing new strategies maintain future forest productivity. Studies focused on environmentally realistic dosages irradiation are scarce. Pinus spp. commercially relevant trees and not much known about their UV. In work, treatment recovery radiata plants with mimicking scenarios,...
The integrative omics approach is crucial to identify the molecular mechanisms underlying high-temperature response in non-model species. Based on future scenarios of heat increase, Pinus radiata plants were exposed a temperature 40°C for period 5 days, including recovered (30 days after last exposure 40°C) analysis. analysis metabolome using complementary mass spectrometry techniques (GC-MS and LC-Orbitrap-MS) allowed reliable quantification 2,287 metabolites. identified metabolites...
Pinus radiata seedlings, the most widely planted pine species in world, were exposed to temperatures within a range mimicking future scenarios based on current models of heat increase. The short-term response P. was studied detail by exploring metabolome, proteome and targeted transcriptome. use complementary mass spectrometry techniques, GC-MS LC-Orbitrap-MS, together with novel bioinformatics tools allowed reliable quantification 2,075 metabolites 901 protein groups. Integrative analyses...
Flooding causes severe crop losses in many parts of the world. Genetic variation flooding tolerance exists species; however, there are few examples for identification genes and their underlying function. We conducted a genome-wide association study (GWAS) 387 Arabidopsis (Arabidopsis thaliana) accessions. Plants were subjected to prolonged submergence followed by desubmergence, seven traits (score, water content, Fv/Fm, concentrations nitrate, chlorophyll, protein, starch) quantified...
Abstract Kales (Brassica oleracea convar. acephala) are fast-growing, nutritious leafy vegetables ideal for year-round indoor farming. However, selection of the best cultivars growth under artificial lighting necessitates a deeper understanding leaf metabolism in different kale types. Here we examined curly-leaved cultivar, Half Tall, and lacinato-type Black Magic, moderate light (130 µmol photons m−2 s−1/22 °C) high (800 s−1/26 conditions. These conditions induced genotype-dependent...
Summary Glucosinolates ( GSL ) of cruciferous plants comprise a major group structurally diverse secondary compounds which act as deterrents against aphids and microbial pathogens have large commercial ecological impacts. While the transcriptional regulation governing biosynthesis modification is now relatively well understood, post‐translational regulatory components that specifically determine structural variation indole glucosinolates not been reported. We show cytoplasmic protein...
Mitochondria are tightly embedded within metabolic and regulatory networks that optimize plant performance in response to environmental challenges. The best-known mitochondrial retrograde signaling pathway involves stress-induced activation of the transcription factor NAC DOMAIN CONTAINING PROTEIN 17 (ANAC017), which initiates protective responses dysfunction Arabidopsis (Arabidopsis thaliana). Posttranslational control elicited responses, however, remains poorly understood. Previous studies...
The continuous atmospheric and environmental deterioration is likely to increase, among others, the influx of ultraviolet B (UV-B) radiation. plants have photoprotective responses, which are complex mechanisms involving different physiological avoid damages caused by this radiation that may lead plant death. We studied adaptive responses UV-B in Pinus radiata, given importance species conifer forests reforestation programs. analyzed photosynthetic activity, pigments content, gene expression...
Redox processes regulate plant/insect responses, but the precise roles of environmental triggers and specific molecular components remain poorly defined. Aphid fecundity plant responses were therefore measured in Arabidopsis thaliana mutants deficient either catalase 2 (cat2), different protein phosphatase 2A (PP2A) subunits or glutathione (cad2, pad2, clt1) under moderate (250 μmol m-2 s-1 ) high (800 light. was decreased pp2a-b'γ, cat2 pp2a-b'γ double relative to wild type irradiance. High...
Sunflower oil at a specific oxidation stage (when several oxygenated alpha,beta-unsaturated aldehydes are generated, mainly 4-hydroperoxy-trans-2-alkenals and 4-hydroxy-trans-2-alkenals), caused 70 degrees C with aeration for 7 days, was administered intraperitoneally to rats. This studied by means of solid phase micro-extraction followed gas chromatography/mass spectrometry (SPME-GC/MS) proton nuclear magnetic resonance ((1)H-NMR). Oxidized sunflower (3 ml/kg/day) male Sprague-Dawley rats...
Needle maturation is a complex process that involves cell growth, differentiation and tissue remodelling towards the acquisition of full physiological competence. Leaf induction mechanisms are well known; however, those underlying competence still poorly understood, especially in conifers. We studied specific epigenetic regulation genes defining organ function (PrRBCS PrRBCA) stress response (PrCSDP2 PrSHMT4) during three stages needle development one de-differentiated control. Gene-specific...
Trans-methylation reactions are intrinsic to cellular metabolism in all living organisms. In land plants, a range of substrate-specific methyltransferases catalyze the methylation DNA, RNA, proteins, cell wall components and numerous species-specific metabolites, thereby providing means for growth acclimation various terrestrial habitats. consume vast amounts S-adenosyl-L-methionine (SAM) as methyl donor several compartments. The inhibitory reaction by-product, S-adenosyl-L-homocysteine...
Evolutionary epigenomics and, more generally, evolutionary functional genomics, are emerging fields that study how non-DNA-encoded alterations in gene expression regulation an important form of plasticity and adaptation. Previous evidence analyzing plants' comparative genomics has mostly focused on comparing same assay-matched experiments, missing the power heterogeneous datasets for conservation inference. To fill this gap, we developed PlantFUN(ctional)CO(nservation) database, which is...
