The aim of this work was to investigate the effects of rare earth elements lanthanum (La3+) and gadolinium (Gd3+) on root system architecture and interactions with low phosphate signaling in Arabidopsis thaliana. Detailed analysis of root system architecture was performed in Arabidopsis WT seedlings and in low phosphorus insensitive mutants lpi1-3 and(More)
The aims of this work were to investigate the aluminum (Al) and phosphate (P) interactions in the regulation of root system architecture of Arabidopsis thaliana seedlings and the contribution of auxin signaling in primary and lateral root growth in response to Al toxicity. Detailed analyses of root system architecture and cell division were performed in(More)
Soil contamination by hexavalent chromium [Cr(VI) or chromate] due to anthropogenic activities has become an increasingly important environmental problem. To date few studies have been performed to elucidate the signaling networks involved on adaptive responses to (CrVI) toxicity in plants. In this work, we report that depending upon its concentration,(More)
Morphological root plasticity optimizes nutrient and water uptake by plants and is a promising target to improve tolerance to metal toxicity. Exposure to sublethal chromate [Cr(VI)] concentrations inhibits root growth, decreases photosynthesis and compromises plant development and productivity. Despite the increasing environmental problem that Cr(VI)(More)
