The contention that quantitative profiles of biomolecules contain information about the physiological state organism has motivated a variety high-throughput molecular profiling experiments. However, unbiased discovery and validation biomolecular signatures from these experiments remains challenge. Here we show Arabidopsis thaliana (Arabidopsis) leaf ionome, or elemental composition, contains such signatures, establish statistical models connect multivariable to defined responses, as iron...
The endodermis in roots acts as a selectivity filter for nutrient and water transport essential growth development. This is enabled by the formation of lignin-based Casparian strips. strip initiated localization domain proteins (CASPs) plasma membrane, at site where will form. Localized CASPs recruit Peroxidase 64 (PER64), Respiratory Burst Oxidase Homolog F, Enhanced Suberin 1 (ESB1), dirigent-like protein, to assemble lignin polymerization machinery. However, factors that control both...
Summary Adverse climatic conditions at the time of flowering severely hinder crop yields and threaten interactions between plants their pollinators. These features depend on a common trait: metabolism flowers. In this Viewpoint article, we aim to provide insight into metabolic changes that occur in flowers response climate emphasize these impact fitness autogamous allogamous species, plant–pollinator interactions, overall ecosystem health. We review biochemical processes lead failure gamete...
We report the results of a genome-wide analysis transcription in Arabidopsis thaliana after treatment with Pseudomonas syringae pathovar tomato. Our time course RNA-Seq experiment uses over 500 million read pairs to provide detailed characterization response infection both susceptible and resistant hosts. The set observed differentially expressed genes is consistent previous studies, confirming extending existing findings about likely play an important role defense syringae. high coverage...
SUMMARY The grapevine industry is of high economic importance in several countries worldwide. Its growing market demand led to an acceleration the entire production processes, implying increasing use water resources at expense environmental balance and hydrological cycle. Furthermore, recent decades climate change consequent expansion drought have further compromised availability, making current agricultural systems even more fragile from ecological economical perspectives. Consequently,...
Here, we demonstrate that the reduction in leaf K+ observed a mutant previously identified an ionomic screen of fast neutron mutagenized Arabidopsis thaliana is caused by loss-of-function allele CPR5, which name cpr5-3. This observation establishes low as new phenotype for alleles CPR5. We investigate factors affecting this cpr5 using double mutants defective salicylic acid (SA) and jasmonic (JA) signalling, gene expression analysis various channels transporters. Reciprocal grafting between...
Flowers are characterized by a plenitude of primary and secondary metabolites flower-specific biosynthetic pathways that all concur to promote plant reproduction the initial stages embryo development. The floral flowers contribute scent colour, which used attract pollinators. Besides, many responsible for conferral colour also serve as photo-protectants towards damaging effects UV solar radiation. whole metabolism is sustained network provide metabolic precursors biosynthesis support flower...
Organisms can rapidly mitigate the effects of environmental changes by changing their phenotypes, known as phenotypic plasticity. Yet, little is about temperature-mediated plasticity traits that are directly linked to plant fitness such flower size. We discovered substantial genetic variation in size temperature both among selfing Arabidopsis thaliana and outcrossing A. arenosa individuals collected from a natural growth habitat. Genetic analysis using panel 290 accession mutant lines...
SUMMARY Food security is threatened by climate change, with heat and drought being the main stresses affecting crop physiology ecosystem services, such as plant–pollinator interactions. We hypothesize that tracking ranking pollinators' preferences for flowers under environmental pressure could be used a marker of plant quality agricultural breeding to increase stress tolerance. Despite increasing relevance most sensitive organs, phenotyping platforms aim at identifying traits resilience...
Abstract Plants synthesize specialized metabolites to facilitate environmental and ecological interactions. During evolution, plants diversified in their potential these metabolites. Quantitative differences metabolite levels of natural Arabidopsis (Arabidopsis thaliana) accessions can be employed unravel the genetic basis for metabolic traits using genome-wide association studies (GWAS). Here, we performed GWAS on seeds a panel 315 A. thaliana accessions, including reference genotypes C24...
Abstract Application of mass spectrometry-based metabolomics enables the detection genotype-related natural variance in metabolism. Differences secondary metabolite composition flowers 64 Arabidopsis thaliana (Arabidopsis) accessions, representing a considerable portion variation this species are presented. The raw metabolomic data accessions and reference extracts derived from flavonoid knockout mutants have been deposited MetaboLights database. Additionally, summary tables floral presented...
Abstract During the maturation phase of flower development, onset anthesis visibly marks transition from buds to open flowers, during which petals stretch out, nectar secretion commences, and pollination occurs. Analysis metabolic changes occurring this developmental has primarily focused on specific classes metabolites, such as pigments scent emission, far less whole network primary secondary metabolites. To investigate at anthesis, we performed multi-platform metabolomics alongside RNA...
Abstract Variation in pollinator foraging behavior can influence pollination effectiveness, community diversity, and plant–pollinator network structure. Although effects of interspecific variation have been widely documented, studies intraspecific are relatively rare. Sex‐specific differences resource use a strong potential source variation, especially species where the phenology males females differ. Differences may arise from encountering different flowering communities, sex‐specific...
