Iron Metabolism-related Gene Identification in Plants
During heat shock, plants undergo a cell death process similar to iron metabolism, but the exact mechanisms and networks remain unknown. Protheragen offers gene identification services related to iron metabolism in plants to help our clients conduct in-depth research on related topics.
Iron metabolism in plants
Among the trace elements essential for plant growth and development, iron is the most demanded and plays an essential role in important plant life activities such as photosynthesis, respiration and chlorophyll synthesis.
Plant Iron Uptake Systems
Over time, plants have evolved an elaborate molecular regulatory system for iron uptake, transport and metabolism in order to obtain sufficient iron from the outside world while avoiding toxicity caused by over-uptake. In general, other plants use System I and Poaceae Barnhart use System II to absorb iron from the soil.
| Plant Type | Iron Absorption System | Related Genes | Description |
| Poaceae Barnhart | System II | IDEF1, IDEF2, IRO2, IRO3, etc. | Fe3+ from the root surroundings can form chelates with lysergic acid and be taken up intracellularly by YS1 and YSL transport carriers, releasing Fe3+ for metabolic use. |
| Other Plants | System I | FRO, IRT, HA, PEZ, NRAMP, YS1/YSL, NAS, NAAT, DMAS, etc. | H+-ATPase pump system, Fe3+ reduction system and Fe2+ transport system. |
Plant Iron Homeostasis Regulation
Plants adapt their root morphology to iron-limited conditions by increasing the density of root hairs and the number of lateral roots. The greater surface area expands the contact between the epidermis and the inter-roots and the lateral roots help to explore fresh soil. If iron suddenly becomes available in the environment, this may lead to an overload of iron in the plant. A variety of genes are involved in post-transcriptional mechanisms that can rapidly stop iron uptake. For example, IRT1 is continuously recycled from the plasma membrane through ubiquitination and internalisation.
