The rhizosphere has a high iron requirement due to plant absorption and microorganism density. Plant roots and microbes in the rhizosphere play a significant role in promoting plant iron (Fe) uptake, which impacts plant development and physiology by influencing nutritional, biochemical, and soil components. The concentration of iron accessible to these live organisms in most cultivated soil is quite low due to its solubility being limited by stable oxyhydroxide, hydroxide, and oxides. The dissolution and solubility rates of iron are also significantly affected by soil pH, microbial population, organic matter content, redox processes, and particle size of the soil. In Fe-limiting situations, plants and soil microbes have used active strategies such as acidification, chelation, and reduction, which have an important role to play in enhancing soil iron availability to plants. In response to iron deficiency, plant and soil organisms produce organic (carbohydrates, amino acids, organic acids, phytosiderophores, microbial siderophores, and phenolics) and inorganic (protons) chemicals in the rhizosphere to improve the solubility of poorly accessible Fe pools. The investigation of iron-mediated associations among plants and microorganisms influences plant development and health, providing a distinctive prospect to further our understanding of rhizosphere ecology and iron dynamics. This review clarifies current knowledge of the intricate dynamics of iron with the end goal of presenting an overview of the rhizosphere mechanisms that are involved in the uptake of iron by plants and microorganisms.<\/jats:p>","DOI":"10.3390\/plants12101945","type":"journal-article","created":{"date-parts":[[2023,5,11]],"date-time":"2023-05-11T01:37:09Z","timestamp":1683769029000},"page":"1945","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":92,"title":["Understanding the Mechanisms of Fe Deficiency in the Rhizosphere to Promote Plant Resilience"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2345-3611","authenticated-orcid":false,"given":"Zolt\u00e1n","family":"Moln\u00e1r","sequence":"first","affiliation":[{"name":"Department of Plant Sciences, Albert K\u00e1zm\u00e9r Faculty of Mosonmagyar\u00f3v\u00e1r, Sz\u00e9chenyi Istv\u00e1n University, H-9200 Mosonmagyar\u00f3v\u00e1r, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1794-5142","authenticated-orcid":false,"given":"Wogene","family":"Solomon","sequence":"additional","affiliation":[{"name":"Department of Plant Sciences, Albert K\u00e1zm\u00e9r Faculty of Mosonmagyar\u00f3v\u00e1r, Sz\u00e9chenyi Istv\u00e1n University, H-9200 Mosonmagyar\u00f3v\u00e1r, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lamnganbi","family":"Mutum","sequence":"additional","affiliation":[{"name":"Department of Plant Sciences, Albert K\u00e1zm\u00e9r Faculty of Mosonmagyar\u00f3v\u00e1r, Sz\u00e9chenyi Istv\u00e1n University, H-9200 Mosonmagyar\u00f3v\u00e1r, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8249-6585","authenticated-orcid":false,"given":"Tibor","family":"Janda","sequence":"additional","affiliation":[{"name":"Agricultural Institute, Centre for Agricultural Research, H-2462 Martonv\u00e1s\u00e1r, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"86","DOI":"10.3389\/fenvs.2017.00086","article-title":"Acquisition and homeostasis of iron in higher plants and their probable role in abiotic stress tolerance","volume":"5","author":"Tripathi","year":"2018","journal-title":"Front.
