Proteomics approaches have been a useful tool for determining the biological roles and functions of individual proteins identifying molecular mechanisms that govern seed germination, vigour viability in response to ageing. In this work dry proteome four Arabidopsis thaliana genotypes, carry introgression fragments at position longevity quantitative trait loci as result display different levels longevity, was investigated. Seeds two physiological states, after-ripened seeds had full...
Abstract Dormancy is a state of metabolic arrest that facilitates the survival organisms during environmental conditions incompatible with their regular course life. Many have deep dormant stages to promote an extended life span (increased longevity). In contrast, plants seed dormancy and longevity described as two traits. Seed defined temporary failure viable germinate in favor germination, whereas viability after dry storage (storability). plants, association has not been studied detail....
Understanding how plants cope with changing habitats is a timely and important topic in plant research. Phenotypic plasticity describes the capability of genotype to produce different phenotypes when exposed environmental conditions. In contrast, constant production set distinct by one mediates bet hedging, strategy that reduces temporal variance fitness at expense lowered arithmetic mean fitness. Both phenomena are thought represent adaptation strategies unstable environments. However,...
Soil salinity is a major contributor to crop yield losses. To improve our understanding of root responses salinity, we developed and exploited real-time salt-induced tilting assay. This assay follows growth upon both gravitropic salt challenges, revealing that bending modulated by Na+ ions, but not osmotic stress. Next, measured this salt-specific response in 345 natural Arabidopsis (Arabidopsis thaliana) accessions discovered genetic locus, encoding the cell wall-modifying enzyme EXTENSIN...
Plants in habitats with unpredictable conditions often have diversified bet-hedging strategies that ensure fitness over a wider range of variable environmental factors. A striking example is the diaspore (seed and fruit) heteromorphism evolved to maximize species survival Aethionema arabicum (Brassicaceae) which external endogenous triggers allow production two distinct diaspores on same plant. Using this dimorphic model, we identified contrasting molecular, biophysical, ecophysiological...
Abstract Soil salinity is a major contributor to crop yield losses. To improve our understanding of root responses salinity, we developed and exploit here real-time salt-induced tilting assay (SITA). This method follows growth upon both gravitropic salt challenges, revealing that bending modulated by but not osmotic stress. Next, this salt-specific response was measured in 345 natural Arabidopsis accessions discovered genetic locus, encoding for the cell-wall modifying enzyme EXTENSIN...
Abstract Background The study of plant photosynthesis is essential for productivity and yield. Thanks to the development high-throughput phenotyping (HTP) facilities, based on chlorophyll fluorescence imaging, photosynthetic traits can be measured in a reliable, reproducible efficient manner. In most state-of-the-art HTP platforms, these are automatedly analyzed at individual level, but information leaf level often restricted by use manual annotation. Automated tracking over time therefore...
The biochemical defence of plants can change during their life-cycle and impact herbivore feeding plant fitness. annual species Aethionema arabicum is part the sister clade to all other Brassicaceae. Hence, it holds a phylogenetically important position for studying crucifer trait evolution. Glucosinolates are essentially Brassicales-specific metabolites involved in defence. Using two Ae. accessions (TUR CYP) we identify substantial differences glucosinolate profiles quantities between...
The genus Aethionema is a sister-group to the core-group of Brassicaceae family that includes Arabidopsis thaliana and Brassica crops. Thus, phylogenetically well-placed for investigation understanding genome trait evolution across family.

ABSTRACT In this study, we found a single quantitative trait locus for photosystem II efficiency (Φ PSII ) in the Arabidopsis Ler-0 x Col-0 recombinant inbred line population. This on chromosome 5 is caused by genetic variation cluster of tandemly repeated SQUALENE EPOXIDASE - LIKE ( SQE-like genes, with unknown function. We show QTL SQE5 , SQE6 and SQE7 genes affecting Φ dose-dependent manner, due to combination functional copies. carries only one copy, while copies SQE 7 . Overexpression...
