Research progress on iron absorption, transport, and molecular regulation strategy in plants

Abstract

Iron is a trace element essential for normal plant life activities and is involved in various metabolic pathways such as chlorophyll synthesis, photosynthesis, and respiration. Although iron is highly abundant in the earth’s crust, the amount that can be absorbed and utilized by plants is very low. Therefore, plants have developed a series of systems for absorption, transport, and utilization in the course of long-term evolution. This review focuses on the findings of current studies of the Fe2+ absorption mechanism I, Fe3+ chelate absorption mechanism II and plant-microbial interaction iron absorption mechanism, particularly effective measures for artificially regulating plant iron absorption and transportation to promote plant growth and development. According to the available literature, the beneficial effects of using microbial fertilizers as iron fertilizers are promising but further evidence of the interaction mechanism between microorganisms and plants is required.

Optimizing Nitrogen Nutrient Management for the Sustainable Enhancement of Secondary Metabolites and Yield in Onion Cultivation

“…Fe is involved in the synthesis of chlorophyll and in other enzymatic and metabolic processes without which plants cannot carry out the plant lifecycle [40,41]. Therefore, in the one fertilization variant N+S+Fe of our experiment, we used Fe at a dose of 5 kg ha −1 .…”

The Influence of Copper and Zinc on Photosynthesis and Phenolic Levels in Basil (Ocimum basilicum L.), Borage (Borago officinalis L.), Common Nettle (Urtica dioica L.) and Peppermint (Mentha piperita L.)

“…In particular, the uptake and transport of iron are greatly influenced by the concentrations and proportions of other heavy metals [43]. Iron is considered an element that plays a key role in the mechanisms of photosynthesis [44].…”

Nanoparticles of Fe3O4 Loaded with Azoxystrobin and Pectin to Enhance Resistance of Rice to Sheath Blight

“…44 Furthermore, the simultaneous presence of iron and silicon in AZOX-AFS-Pec NPs proved beneficial. Both elements have been independently established to promote rice chlorophyll synthesis, chloroplast development, 45 and activation of photosynthesis. 46 The coexistence of these elements in AZOX-AFS-Pec NPs not only effectively prevents and controls rice sheath blight but also fosters rice growth.…”
