Linking the key physiological functions of essential micronutrients to their deficiency symptoms in plants

Abstract

SummaryIn this review, we untangle the physiological key functions of the essential micronutrients and link them to the deficiency responses in plants. Knowledge of these responses at the mechanistic level, and the resulting deficiency symptoms, have improved over the last decade and it appears timely to review recent insights for each of them. A proper understanding of the links between function and symptom is indispensable for an accurate and timely identification of nutritional disorders, thereby informing the design and development of sustainable fertilization strategies. Similarly, improved knowledge of the molecular and physiological functions of micronutrients will be important for breeding programmes aiming to develop new crop genotypes with improved nutrient‐use efficiency and resilience in the face of changing soil and climate conditions.

“…In addition, because an earlier study reported that sulfate transporters are also able to transport Mo (Maillard et al 2016), it cannot be excluded that the SULTR3.5 transporter could be also involved in transporting Mo to the symbiosome. Notably, many studies have reported that Mo and S are both crucial elements for the synthesis of three metal prosthetic groups ([4Fe-4S], P-cluster and FeMo-co) required for synthesis and activity of the nitrogenase complex in bacteria (Schneider et al 2019;Lilay et al 2024).…”
