Iron Uptake Strategies in Rice: Exploring YSL Genes and Nutritional Enhancement

Iron plays a critical role as a micronutrient indispensable for the optimal growth and development of plants, engaging in various physiological processes. Inadequate iron levels can lead to chlorosis, hindered growth, and reduced crop yields, detrimentally affecting agricultural output and human nutrition. The utilization of iron sulfate has emerged as a pivotal method to address iron deficiency in plants, primarily through soil and foliar applications. Its effectiveness in promoting plant growth, facilitating chlorophyll production, and improving overall crop yield underscores its importance in farming techniques. Additionally, recent studies underscore the significance of YSL (yellow stripe–like) genes in iron transportation, particularly in rice plants. These genes play a vital role in iron absorption and distribution within the plant, particularly in rice, impacting its utilization. Comprehending the mechanisms regulated by YSL genes in iron transportation provides valuable insights into enhancing crop iron uptake efficiency and fortifying plant resistance against iron deficiency. This review offers a thorough examination of the crucial role of iron in plants, the efficacy of iron sulfate in alleviating iron deficiency, and the importance of YSL genes in iron transportation, offering valuable perspectives for sustainable agricultural approaches and strategies for crop improvement.
