Auxin represents a key signal in plants, regulating almost every aspect of their growth and development. Major breakthroughs have been made dissecting the molecular basis auxin transport, perception, response. In contrast, how plants control metabolism homeostasis major form indole-3-acetic acid (IAA), remains unclear. this paper, we initially describe function Arabidopsis thaliana gene DIOXYGENASE FOR AUXIN OXIDATION 1 (AtDAO1). Transcriptional translational reporter lines revealed that...
Indole-3-acetic acid (IAA) controls a plethora of developmental processes. Thus, regulation its concentration is great relevance for plant performance. Cellular IAA depends on transport, biosynthesis and the various pathways inactivation, including oxidation conjugation. Group II members GRETCHEN HAGEN 3 (GH3) gene family code acyl amido synthetases catalysing conjugation to amino acids. However, high degree functional redundancy among them has hampered thorough analysis their roles in...
Indole-3-acetic acid (IAA), the most common form of auxin, is involved in a great range plant physiological processes. IAA synthesized from amino tryptophan and can be transported inactivated myriad ways. Despite intense research efforts, there are still dark corners our comprehension metabolism its interplays with other pathways. Genetic screens powerful tool for unbiasedly looking new players given biological process. However, pleiotropism auxin-related phenotypes indirect effects make it...
Auxin (indole-3-acetic acid, IAA) plays fundamental roles as a signalling molecule during numerous plant growth and development processes. The formation of local auxin gradients maxima/minima, which is very important for these processes, regulated by metabolism (biosynthesis, degradation, conjugation) well transport. When studying pathways it crucial to combine data obtained from genetic investigations with the identification quantification individual metabolites. Thus, facilitate efforts...
The levels of the important plant growth regulator indole-3-acetic acid (IAA) are tightly controlled within tissues to spatiotemporally orchestrate concentration gradients that drive and development. Metabolic inactivation bioactive IAA is known participate in modulation maxima minima. can be irreversibly inactivated by oxidation conjugation aspartate glutamate. Usually overlooked because its reversible nature, most abundant inactive form IAA-glucose (IAA-glc) conjugate. Glycosylation...
Abstract Background Gaseous phytohormone ethylene levels are directly influenced by the production of its immediate non-volatile precursor 1-aminocyclopropane-1-carboxylic acid (ACC). Owing to strongly acidic character ACC molecule, quantification has been difficult perform. Here, we present a simple and straightforward validated method for accurate not only levels, but also major members other important phytohormonal classes – auxins, cytokinins, jasmonic acid, abscisic salicylic from same...
Summary Dynamic regulation of the concentration natural auxin (IAA) is essential to coordinate most physiological and developmental processes responses environmental changes. Oxidation IAA a major pathway control concentrations in angiosperms and, along with conjugation, respond perturbation homeostasis. However, these regulatory mechanisms remain poorly investigated conifers. To reduce this knowledge gap, we different contributions inactivation pathways MS‐based quantification metabolites...
Whole-genome duplication events have driven to a large degree the evolution of angiosperm genomes. Although majority redundant gene copies after genome are lost, subfunctionalization or balance account for retention copies. The Arabidopsis 80S ribosome represents an excellent model test hypothesis as it consists 80 ribosomal proteins, all them encoded by genes belonging small families. Here, we present isolation mutant alleles APICULATA2 (API2) and RPL36aA paralogous genes, which encode...
Abstract Translational regulation, exerted by the cytosolic ribosome, has been shown to participate in establishment of abaxial-adaxial polarity Arabidopsis thaliana : many hypomorphic and null alleles genes encoding proteins ribosome enhance leaf defects asymmetric leaves1 ( as1 ) as2 mutants. Here, we report identification SCABRA1 SCA1 nuclear gene, whose loss-of-function mutations also In striking contrast other previously known enhancers phenotypes caused mutations, found that encodes a...
The chloroplasts of land plants contain internal membrane systems, the thylakoids, which are arranged in stacks called grana. Because grana have not been found Cyanobacteria, evolutionary origin genes controlling structural and functional diversification thylakoidal membranes remains unclear. angulata10-1 (anu10-1) mutant, exhibits pale-green rosettes, reduced growth, deficient leaf lateral expansion, resulting presence prominent marginal teeth, was isolated. Palisade cells anu10-1 larger...
The information that connects genotypes and phenotypes is essentially embedded in research articles written natural language. To facilitate access to this knowledge, we constructed a framework for the curation of scientific literature studying molecular mechanisms control leaf growth development Arabidopsis thaliana (Arabidopsis). Standard structured statements, called relations, were designed capture diverse data types, including gene expression linked genotype description, conditions,...
The spatial location and timing of plant developmental events are largely regulated by the well balanced effects auxin cytokinin phytohormone interplay. Together with transport, localized metabolism regulates concentration gradients their bioactive forms, ultimately eliciting growth responses. In order to explore dynamics during early seedling in Theobroma cacao (cacao), we have performed metabolite profiling hypocotyls root sections at different times using ultra-high-performance liquid...
