Higher plants evolved mechanisms of uptake, distribution and accumulation of trace metals essential for the proper functioning of the organism (e.g., copper, zinc). Non-essential metals (e.g., cadmium, arsenic, lead) can also enter plant cells using the routes dedicated to the essential ones, because of the shared similar chemical and physical properties. Generally, trace elements are very reactive, able to generate reactive oxygen species and to interact or bind various organic ligands composed of C, H, O, N, P or S. Thus, after entering to the cells, metals are transported and sequestered mainly in a complex form, bound with amino acids, organic acids, peptides or specific metal-binding ligands. Considering diverse properties (e.g., pH value, abundancy of ions, redox state) characterizing cells, tissues and phloem or xylem sap, plants use various ligands to form stable complexes in different conditions. This literature review aims to provide a comprehensive overview on the role of low-molecular weight acids and peptides in trace metals translocation.

“…In Arabidopsis, pcr2 lossof-function mutants accumulate Zn in roots, suggesting a role of in root-to-shoot translocation of Zn, independent of HMA2 and HMA4 (Song et al, 2010). Furthermore, it was proved that AtFRD3 is involved in loading Zn into xylem (Pineau et al, 2012). Zn can also be exported from the roots in the form of Zn complexes.…”

“…Exploring natural variation has contributed to the identification of quantitative trait loci controlling RSA development under control and abiotic stress conditions (Mouchel et al, 2004;Rosas et al, 2013;Meijón et al, 2014;Slovak et al, 2014). Root growth under potassium, iron, or phosphate starvation has been linked to allelic polymorphisms (Reymond et al, 2006;Pineau et al, 2012;Kellermeier et al, 2013), whereas salt-induced changes in RSA have partially been explained by differences in the sensitivity to ABA within Arabidopsis accessions (Julkowska et al, 2014). However, natural variation in root responses to combinations of stresses has not been studied before.…”

Phosphate-dependent root system architecture responses to salt stress

Nutrient availability and salinity of the soil affect the growth and development of plant roots. Here, we describe how inorganic phosphate (Pi) availability affects the root system architecture (RSA) of Arabidopsis (Arabidopsis thaliana) and how Pi levels modulate responses of the root to salt stress. Pi starvation reduced main root length and increased the number of lateral roots of Arabidopsis Columbia-0 seedlings. In combination with salt, low Pi dampened the inhibiting effect of mild salt stress (75 mM) on all measured RSA components. At higher salt concentrations, the Pi deprivation response prevailed over the salt stress only for lateral root elongation. The Pi deprivation response of lateral roots appeared to be oppositely affected by abscisic acid signaling compared with the salt stress response. Natural variation in the response to the combination treatment of salt and Pi starvation within 330 Arabidopsis accessions could be grouped into four response patterns. When exposed to double stress, in general, lateral roots prioritized responses to salt, while the effect on main root traits was additive. Interestingly, these patterns were not identical for all accessions studied, and multiple strategies to integrate the signals from Pi deprivation and salinity were identified. By genome-wide association mapping, 12 genomic loci were identified as putative factors integrating responses to salt stress and Pi starvation. From our experiments, we conclude that Pi starvation interferes with salt responses mainly at the level of lateral roots and that large natural variation exists in the available genetic repertoire of accessions to handle the combination of stresses.
