Cadmium (Cd) tolerance seems to be a constitutive species-level trait in Arabidopsis halleri sp. halleri. Therefore, an interspecific cross was made between A. and its closest nontolerant interfertile relative, lyrata petraea, first-generation backcross population (BC1) used map quantitative loci (QTL) for Cd tolerance. Three QTL were identified, which explained 43%, 24%, 16% of the phenotypic variation mapping population. Heavy metal transporting ATPases4 (HMA4), encoding predicted heavy...
Abstract The species Arabidopsis halleri, an emerging model for the study of heavy metal tolerance and accumulation in plants, has evolved a high level constitutive zinc tolerance. Mapping quantitative trait loci (QTL) was used to investigate genetic architecture this species. A first-generation backcross progeny A. halleri ssp. from highly contaminated industrial site its nontolerant relative lyrata petraea produced QTL mapping map covering most genome constructed using 85 markers. Among...
A contiguous assembly of the inbred 'EL10' sugar beet (Beta vulgaris ssp. vulgaris) genome was constructed using PacBio long-read sequencing, BioNano optical mapping, Hi-C scaffolding, and Illumina short-read error correction. The EL10.1 540 Mb, which 96.2% contained in nine chromosome-sized pseudomolecules with lengths from 52 to 65 31 contigs a median size 282 kb that remained unassembled. Gene annotation incorporating RNA-seq data curated sequences via MAKER pipeline generated 24,255 gene...
• The purpose of this study was to investigate the relationship between chemical form and localization zinc (Zn) in plant leaves their Zn accumulation capacity. An interspecific cross Arabidopsis halleri sp. lyrata petrea segregating for used. Zinc speciation distribution parent plants selected F1 F2 progenies were investigated by spectroscopic microscopic techniques analyses. A correlation observed proportion being octahedral coordination complexed organic acids free solution (Zn–OAs +...
Summary Eukaryotic translation initiation factors (eIFs) are important for mRNA but also pivotal plant‐virus interaction. Most of these interactions were found between plant eIFs and the viral protein genome‐linked (VPg) potyviruses. In case lost interaction due to mutation or deletion eIFs, subsequent replication within its host is negatively affected, resulting in a recessive resistance. Here we report identification Beta vulgaris Bv‐eIF(iso)4E as susceptibility factor towards VPg‐carrying...
The influence of antrectomy and antrum exclusion on the enterochromaffin like cell kinetics in gastric mucosa rat was studied using a combination histamine immunocytochemistry autoradiography after vivo labelling with tritiated thymidine. In all experimental groups, cells were found to incorporate DNA precursor, thus indicating an ability divide. serum gastrin concentration raised by reduced antrectomy. After exclusion, proliferation rate increased as indicated doubling index resulting...
• This study sought to determine the main genomic regions that control zinc (Zn) hyperaccumulation in Arabidopsis halleri and examine genotype × environment effects on phenotypic variance. To do so, quantitative trait loci (QTLs) were mapped using an interspecific A. lyrata petraea F2 population. The progeny as well representatives of parental populations cultivated soils at two different Zn concentrations. A linkage map was constructed 70 markers. In both low high pollution treatments,...
• This study describes the quantitative trait locus (QTL) analysis of cadmium (Cd), zinc (Zn), iron (Fe), potassium (K), magnesium (Mg) and calcium (Ca) accumulation in pseudometallophyte Arabidopsis halleri under conditions Cd excess using an interspecific A. × lyrata F2 population. Our data provide evidence for implication one major QTL hyperaccumulation halleri, suggests that tolerance are not independent halleri. Moreover, loci responsible Zn absence appear to be same when is present at...
Abstract The capacity to tolerate freezing temperatures limits the geographical distribution of many plants, including several species agricultural importance. However, genes involved in tolerance remain largely unknown. Here, we describe variation constitutive that occurs among worldwide accessions Arabidopsis thaliana . We found although plants from high latitudes tend be more tolerant than low latitudes, environmental factors shape cold adaptation differ across range. Consistent with...
In sugar beet (Beta vulgaris altissima), bolting tolerance is an essential agronomic trait reflecting the response of genotypes after vernalization. Genes involved in induction have now been identified, and evidence suggests that epigenetic factors are their control. Indeed, time course amplitude DNA methylation variations shoot apical meristem shown to be critical inducing bolting, a few functional targets during vernalization identified. However, molecular mechanisms controlling levels...
Abstract Metallophyte species that occur naturally on metal‐enriched soils represent major biological resources for the improvement of phytoremediation, a benign and cost‐effective technology uses plants to clean up anthropogenic metal‐polluted soils. Within last decade, molecular genetic studies carried out several model organisms (including Arabidopsis halleri ) have considerably enhanced our understanding metal tolerance hyperaccumulation in plants, but identification genes interest...
