Under heterotrophic conditions, carbohydrate oxidation inside the mitochondrion is primary energy source for cellular metabolism. However, during energy-limited alternative substrates are required to support respiration. Amino acid in plant cells plays a key role this by generating electrons that can be transferred mitochondrial electron transport chain via transfer flavoprotein/ubiquinone oxidoreductase system. Autophagy, catabolic mechanism macromolecule and protein recycling, allows...
Stomata control the exchange of CO2 and water vapor in land plants. Thus, whereas a constant supply is required to maintain adequate rates photosynthesis, accompanying losses must be tightly regulated prevent dehydration undesired metabolic changes. Accordingly, uptake or release ions metabolites from guard cells necessary achieve normal stomatal function. The AtQUAC1, an R-type anion channel responsible for malate cells, essential efficient closure. Here, we demonstrate that mutant plants...
The tricarboxylic acid (TCA) cycle, a crucial component of respiratory metabolism, is composed set eight enzymes present in the mitochondrial matrix. However, most TCA cycle are encoded nucleus higher eukaryotes. In addition, evidence has accumulated demonstrating that nuclear genes were acquired from genome during course evolution. For this reason, we here analyzed evolutionary history all attempt to better understand origin these nuclear-encoded proteins. Our results indicate prior...
Cyanobacteria is a remarkable group of prokaryotic photosynthetic microorganisms, with several genera capable fixing atmospheric nitrogen (N2) and presenting wide range morphologies. Although the nitrogenase complex not present in all cyanobacterial taxa, it spread across strains. The has also high theoretical potential for biofuel production, since H2 by-product produced during N2 fixation. In this review we discuss significance relatively variety cell morphologies metabolic strategies that...
Juvenile-to-adult phase transition is marked by changes in leaf morphology, mostly due to the temporal development of shoot apical meristem, a phenomenon known as heteroblasty. Sugars and microRNA-controlled modules are components heteroblastic process Arabidopsis thaliana leaves. However, our understanding about their roles during phase-changing other species, such Passiflora edulis, remains limited. Unlike Arabidopsis, P. edulis (a semi-woody perennial climbing vine) undergoes remarkable...
In cellular circumstances where carbohydrates are scarce, plants can use alternative substrates for energetic maintenance. plants, the main protein reserve is present in chloroplast, which contains most of total leaf proteins and represents a rich source nitrogen amino acids. Autophagy plays key role chloroplast breakdown, well-recognised symptom both natural stress-induced plant senescence. Remarkably, an autophagic-independent route degradation associated with vesiculation (CV) gene was...
Abstract Compelling evidence supports the potential application of wild crop relatives in Solanum breeding. Efforts have been made to generate genomic data from plants assess insertion advantageous traits into species. South America hosts a broad range that not widely evaluated at molecular level. sessiliflorum is species shows tolerance Ralstonia solanacearum and nematode infections. The Illumina platform was used construct transcriptome S. . were analyzed using bioinformatics tools for...
Abstract Plants are constantly exposed to environmental changes that affect their performance. Metabolic adjustments crucial controlling energy homoeostasis and plant survival, particularly during stress. Under carbon starvation, coordinated reprogramming is initiated adjust metabolic processes, which culminate in premature senescence. Notwithstanding, the regulatory networks modulate transcriptional control low remain poorly understood. Here, we show WRKY45 transcription factor highly...
Plant respiration mostly depends on the activity of glycolysis and oxidation organic acids in tricarboxylic acid cycle to synthesize ATP. However, during stress situations plant cells also use amino as alternative substrates donate electrons through electron-transfer flavoprotein (ETF)/ETF:ubiquinone oxidoreductase (ETF/ETFQO) complex mitochondrial electron transport chain (mETC). Given this, we investigated changes oxidative phosphorylation (OXPHOS) system Arabidopsis thaliana cell culture...
Lysine (Lys) connects the mitochondrial electron transport chain to amino acid catabolism and tricarboxylic cycle. However, our understanding of how a deficiency in Lys biosynthesis impacts plant metabolism growth remains limited. Here, we used previously characterized Arabidopsis mutant (dapat) with reduced activity enzyme L,L-diaminopimelate aminotransferase investigate physiological metabolic impaired biosynthesis. Despite displaying similar stomatal conductance internal CO2...
The importance of the alternative donation electrons to ubiquinol pool via electron-transfer flavoprotein/electron-transfer flavoprotein:ubiquinone oxidoreductase (ETF/ETFQO) complex has been demonstrated. However, functional significance this pathway during seed development and germination remains be elucidated. To assess function pathway, we performed a detailed metabolic transcriptomic analysis Arabidopsis mutants test molecular consequences dysfunctional ETF/ETFQO pathway. We demonstrate...
Plants are negatively affected by aluminum (Al) in acidic soils (pH ≤ 5.0), which impair root growth and ultimately plant yield. Organic acids closely related to Al neutralization improving the metal tolerance with an expansive metabolic cost. We reasoned that phenotypic, metabolic, genetic responses of three Arabidopsis thaliana ecotypes, Columbia (Col-0), Wassilewskija (Ws) Landsberg erecta (Ler) may vary. By comparing respective control plants Al-exposed plants, ecotypes Col-0 Ws...
Autophagy is a highly conserved cellular mechanism in eukaryotes allowing the degradation of cell constituents. It crucial significance both homeostasis and nutrient recycling. During energy limited conditions plant cells can metabolize alternative respiratory substrates, such as amino acids, providing electrons to mitochondrial metabolism via tricarboxylic acid (TCA) cycle or electron transfer flavoprotein/ flavoprotein ubiquinone oxidoreductase (ETF/ETFQO) system. Our recent study reveals...
