Abstract Key message The activation of the antioxidant system under stress combination is a transmissible trait from rootstock to scion. Therefore, selection key improve crop performance and sustainable production changing climate conditions. Climate change altering weather conditions such as mean temperatures precipitation patterns. Rising temperatures, especially in certain regions, accelerates soil water depletion increases drought risk, which affects agriculture yield. Previously, our...
Drought, heat and high irradiance are abiotic stresses that negatively affect plant development reduce crop productivity. The confluence of these three factors is common in nature, causing extreme situations for plants compromise their viability. Drought increase the saturation photosystem reaction centers, increasing sensitivity to irradiance. In addition, stress conditions II (PSII) integrity, alter redox balance electron transport chain decrease photosynthetic rate. Here, we studied...
Environmental changes derived from global warming and human activities increase the intensity frequency of stressful conditions for plants. Multiple abiotic factors acting simultaneously enhance stress pressure drastically reduce plant growth, yield, survival. Stress combination causes a specific situation that induces particular response different to sum responses individual stresses. Here, by comparing transcriptomic proteomic profiles combinations in two citrus genotypes, Carrizo citrange...
Age affects the production of secondary metabolites, but how developmental cues regulate metabolism remains poorly understood. The achiote tree (Bixa orellana L.) is a source bixin, an apocarotenoid used in diverse industries worldwide. Understanding age-dependent mechanisms control bixin biosynthesis great interest for plant biology and economic reasons. Here we overexpressed miRNA156 (miR156) B. to comprehensively study effects miR156-SQUAMOSA PROMOTER BINDING PROTEIN-LIKE (SPL) module on...
Abstract Long-term subculture plays an essential role in the large-scale multiplication and production of somatic plantlets. We investigated effects long-term on vitro shoot development ex rooting associated with changes hormones protein profiles C. fissilis . The number subcultures shoots induced a decrease response. reduction adventitious root (AR) formation was decreases contents indole-3-acetic acid (IAA), abscisic (ABA), 12-oxo phytodienoic (OPDA), putrescine (Put), spermine increases...
Abstract Dalbergia nigra is an endangered species from the Brazilian Atlantic Rainforest, and in vitro propagation can be applied for conservation of this species. The aim study was to establish ex rooting D. evaluate alterations polyamines (PAs) protein profiles during shoot development . effect MS WPM culture media on germination tested (%). For induction, explants apical cotyledonary nodal segments 45-day-old seedlings were inoculated medium supplemented with benzyladenine (BA; 0, 2.5 5...
ABSTRACT Attempts to improve the ascorbate (AsA) content of plants are still dealing with limited understanding why exists a wide variability this powerful anti-oxidant molecule in different plant sources, species and environmental situations. In mitochondria, last step AsA synthesis is catalyzed by enzyme L-galactone-1,4-lactone dehydrogenase (L-GalLDH). By using GalLDH-RNAi silencing lines, biochemical proteomic approaches, we here discovered that, addition accumulate antioxidant,...
Abstract Polyamines (PAs) and proteins have been demonstrated to be fundamental for in vitro shoot development of Cedrela fissilis. We evaluated the influence 6-benzyladenine (BA) putrescine (Put) on growth shoots, PA metabolism proteomic profiles C. fissilis .The longest shoots were obtained under 2.5 μM BA + mM Put treatment. The inhibition synthesis by D-arginine (D-arg) reduced activities biosynthesis enzymes arginine decarboxylase (ADC) ornithine (ODC) endogenous contents free Put,...
Summary Age affects the production of secondary metabolites, but how developmental cues regulate metabolism remains poorly understood. Annatto (Bixa orellana L.) is a source bixin, an apocarotenoid used in world’s food industry worldwide. Understanding age-dependent mechanisms control bixin biosynthesis great interest for plant biology and pharmaceutical, cosmetic, textile industries. Here, we genetic molecular tools to unravel role annatto age regulated miRNA156 (miR156) targeted SQUAMOSA...
