Exploring the Effects of VgPIP1;2 Overexpression in the Roots of Young Rice Plants: Modifications in Root Architecture, Transcriptomic and Metabolomic Profiles Open
Rice (Oryza sativa) is a major staple crop that feeds over half of the world’s population. However, its cultivation depends heavily on nitrogen fertilizers, which increase both environmental impacts and production costs. Enhancing the sust…

Comparison of linkage and association mapping in MAGIC lines identifies <i>AtMTP3</i> as a new gene controlling natural variation in leaf zinc concentration in Arabidopsis Open
The Arabidopsis thaliana MAGIC lines are the result of extensive recombination among 19 accessions, which allows a direct comparison of association and linkage mapping using the same population. We used both approaches to map the genetic b…

Stromal Ascorbate Peroxidase (OsAPX7) Modulates Drought Stress Tolerance in Rice (Oryza sativa) Open
Chloroplast ascorbate peroxidases exert an important role in the maintenance of hydrogen peroxide levels in chloroplasts by using ascorbate as the specific electron donor. In this work, we performed a functional study of the stromal APX in…

Enhanced expression of OsNAC5 leads to up-regulation of OsNAC6 and changes rice (Oryza sativa L.) ionome Open
NAC transcription factors are plant-specific proteins involved in many processes during the plant life cycle and responses to biotic and abiotic stresses. Previous studies have shown that stress-induced OsNAC5 from rice (Oryza sativa L.) i…

Countering elevated <span>CO<sub>2</sub></span> induced Fe and Zn reduction in <i>Arabidopsis</i> seeds Open
Summary Growth at increased concentrations of CO 2 induces a reduction in seed zinc (Zn) and iron (Fe). Using Arabidopsis thaliana , we investigated whether this could be mitigated by reducing the elevated CO 2 ‐induced decrease in transpi…

Ascorbate Peroxidase Neofunctionalization at the Origin of APX-R and APX-L: Evidence from Basal Archaeplastida Open
Ascorbate peroxidases (APX) are class I members of the Peroxidase-Catalase superfamily, a large group of evolutionarily related but rather divergent enzymes. Through mining in public databases, unusual subsets of APX homologs were identifi…

Ascorbate peroxidase neofunctionalization at the origin of APx-R and APx-L: evidences from basal Archaeplastida Open
Ascorbate peroxidases (APx) are class I members of the non-animal peroxidases superfamily, a large group of evolutionarily related enzymes. Through mining in public databases, our group has previously identified two unusual subsets of APx …

OsMTP11 is localised at the Golgi and contributes to Mn tolerance Open
Membrane transporters play a key role in obtaining sufficient quantities of manganese (Mn) but also in protecting against Mn toxicity. We have characterized OsMTP11, a member of the Cation Diffusion Facilitator/Metal Tolerance Protein (CDF…

Improving zinc accumulation in cereal endosperm using Hv<span>MTP</span>1, a transition metal transporter Open
Summary Zinc (Zn) is essential for all life forms, including humans. It is estimated that around two billion people are deficient in their Zn intake. Human dietary Zn intake relies heavily on plants, which in many developing countries cons…

A walk on the wild side: Oryza species as source for rice abiotic stress tolerance Open
Oryza sativa, the common cultivated rice, is one of the most important crops for human consumption, but production is increasingly threatened by abiotic stresses. Although many efforts have resulted in breeding rice cultivars that are rela…

Stress Signaling Responses in Plants Open
Plants undergo continuous exposure to various biotic and abiotic stresses in their natural environment. To survive under such conditions, plants exhibit stress tolerance or stress avoidance through acclimation and adaptation mechanisms tha…
