During seed germination, iron (Fe) stored in vacuoles is exported by the redundant NRAMP3 and NRAMP4 transporter proteins. A double nramp3 nramp4 mutant unable to mobilize Fe stores does not develop absence of external Fe. We used RNA sequencing compare gene expression wild type during germination early seedling development. Even though sufficient was supplied, Fe-responsive transcription factors bHLH38, 39, 100, 101 their downstream targets FRO2 IRT1 mediating uptake were strongly...
The Anthropocene epoch is associated with the spreading of metals in environment increasing oxidative and genotoxic stress on organisms. Interestingly, c. 520 plant species growing metalliferous soils acquired capacity to accumulate tolerate a tremendous amount nickel their shoots. wide phylogenetic distribution these suggests that hyperaccumulation evolved multiple times independently. However, exact nature mechanisms whether they have been recruited convergently distant not known. To...
Cadmium (Cd) accumulation in agricultural soils constitutes a serious problem for crop yields and food safety. It is known that proline (Pro) can rapidly accumulate plant tissues response to abiotic stress. To analyze the potential protective effect of Pro against Cd toxicity, we compared stress wild-type (WT) Medicago truncatula transgenic line had previously obtained characterized (p18), which expressed Δ 1-pyrroline-5-carboxylate synthetase gene from Vigna aconitifolia (VaP5CS),...
Abstract In response to our ever‐increasing demand for metals, phytotechnologies are being developed limit the environmental impact of conventional metal mining. However, development these technologies, which rely on plant species able tolerate and accumulate is partly limited by lack knowledge underlying molecular mechanisms. this work, we aimed better understand role transporters IRON REGULATED 1/FERROPORTIN (IREG/FPN) family from nickel hyperaccumulator Leucocroton havanensis...
Cadmium (Cd) pollution in soils is an increasing problem worldwide, and it affects crop production safety. We identified Cd-tolerant -sensitive cultivars by testing 258 accessions of Medicago truncatula at seedling stage, using the relative root growth (RRG) as indicator Cd tolerance. The factorial analysis (principal component method) different parameters analyzed revealed a clear differentiation between depending on trait (tolerant or sensitive). obtained normalized index tolerance, which...
The Anthropocene epoch is associated with the spreading of metals in environment increasing oxidative and genotoxic stress on living organisms 1,2 . Once regarded as a curiosity, plants hyperaccumulating are now envisioned an opportunity to remediate metal contaminated soils. About 500 plant species adapted metalliferous soils acquired capacity hyperaccumulate (>0.1% dry weight) nickel their shoot 3 phylogenetic distribution these hyperaccumulators 50 families suggest that this complex...

The Anthropocene epoch is associated with the spreading of metals in environment increasing oxidative and genotoxic stress on living organisms. Metalliferous soils such as serpentine can host peculiar plants called hyperaccumulators due to their capacity accumulate tremendous amount metal shoot (e.g. >0.1% dry weight for nickel). Once regarded a curiosity, hyperaccumulating are now envisioned an opportunity remediate contaminated soils. wide phylogenetic distribution nickel (~500 species)...
Abstract The remarkable capacity of plants to tolerate and accumulate tremendous amount nickel is a complex adaptative trait that appeared independently in more than 700 species distributed about fifty families. Nickel hyperaccumulation thus proposed as model investigate the evolution traits plants. However, mechanisms involved are still poorly understood part because comparative transcriptomic analyses struggle identify genes linked this from wide diversity species. In work, we have...

However, development these technologies, which rely on plant species able tolerate and accumulate is partly limited by lack knowledge underlying molecular mechanisms. this work, we aimed identify genes involved in nickel hyperaccumulation Euphorbiaceae Leucocroton havanensis . Using transcriptomic data, identified two homologous...
