“…Although Zn is not expected to be a key regulator of ectomycorrhizal development nor to be extremely scarce at the symbiotic interface, availability of this element may have an impact on the fitness of both individual symbiotic partners and the mutualism in particular environments. Micronutrient deficiencies are rarely observed in natural forests but severe Zn deficiency in tree plantations has been reported previously ( Thorn and Robertson, 1987 ; Boardman and McGuire, 1990 ). Moreover, trees are sensitive to high soil Zn concentrations.…”

Zinc (Zn) is an essential micronutrient but may become toxic when present in excess. In Zn-contaminated environments, trees can be protected from Zn toxicity by their root-associated micro-organisms, in particular ectomycorrhizal fungi. The mechanisms of cellular Zn homeostasis in ectomycorrhizal fungi and their contribution to the host tree’s Zn status are however not yet fully understood. The aim of this study was to identify and characterize transporters involved in Zn uptake in the ectomycorrhizal fungus Suillus luteus, a cosmopolitan pine mycobiont. Zn uptake in fungi is known to be predominantly governed by members of the ZIP (Zrt/IrtT-like protein) family of Zn transporters. Four ZIP transporter encoding genes were identified in the S. luteus genome. By in silico and phylogenetic analysis, one of these proteins, SlZRT1, was predicted to be a plasma membrane located Zn importer. Heterologous expression in yeast confirmed the predicted function and localization of the protein. A gene expression analysis via RT-qPCR was performed in S. luteus to establish whether SlZRT1 expression is affected by external Zn concentrations. SlZRT1 transcripts accumulated almost immediately, though transiently upon growth in the absence of Zn. Exposure to elevated concentrations of Zn resulted in a significant reduction of SlZRT1 transcripts within the first hour after initiation of the exposure. Altogether, the data support a role as cellular Zn importer for SlZRT1 and indicate a key role in cellular Zn uptake of S. luteus. Further research is needed to understand the eventual contribution of SlZRT1 to the Zn status of the host plant.

“…Past studies have focused on C, N, and P but few studies focused on iron probably due to the general impression about its secondary importance in biological systems. Iron however is an essential nutrient as a key element in a variety of enzymes (Boardman andMcguire, 1990, Knight, 1975) and high concentration of iron oxides strongly influence the bioavailability of carbon and other nutrients (P) via biochemical coupling reactions or adsorption capacity (Backes et al, 1995;Eusterhues et al, 2005;Sanchez, 1976;Schwertmann, 1991).…”

“…Deficiency of Zn causes several disorders in plants and the most common symptoms include: inhibited growth, reduced petioles and the internodes, little deformed leaves (little leaves) that form symptoms of rosette in the initial stages of dicots and a fan-shaped stem in monocots (Snowball and Robson 1986). Dieback (apex of shoot dies) occurs under severe deficiency of Zn, for example, in South Australian forest plantations (Boardman and McGuire 1990). These above-said symptoms are often combined with necrosis, mottled leaf, necrotic patches, thin stem and patchy appearance (Brennan et al 1993;Benton 2003).…”

Zinc (Zn) is the second most abundant transition element after iron in living organisms and is categorized as an essential micronutrient to plants. It takes part in various cellular and physiological functions of plants and exerts a positive role in growth, development and yield. Zn serves structural, catalytic and regulatory roles in enormous numbers of proteins and enzymes. Hence, it is important to get the knowledge and understanding about the dynamics and biochemistry of Zn in soil, its uptake, transport and response of plants to Zn deficiency and in achieving the sustainable solutions for the same in plants. Zn deficiency seems to be an extensive and common problem in crops worldwide, resulting in severe losses in yield affecting nutritional quality. Bearing in mind the current state, an attempt has been made to further dissect the uptake, transport, assimilation, role, deficiency, toxicity symptoms of Zn and economic losses triggered in plants.
