Cross-Talks Between Macro- and Micronutrient Uptake and Signaling in Plants

Abstract

In nature, land plants as sessile organisms are faced with multiple nutrient stresses that often occur simultaneously in soil. Nitrogen (N), phosphorus (P), sulfur (S), zinc (Zn), and iron (Fe) are five of the essential nutrients that affect plant growth and health. Although these minerals are relatively inaccessible to plants due to their low solubility and relative immobilization, plants have adopted coping mechanisms for survival under multiple nutrient stress conditions. The double interactions between N, Pi, S, Zn, and Fe have long been recognized in plants at the physiological level. However, the molecular mechanisms and signaling pathways underlying these cross-talks in plants remain poorly understood. This review preliminarily examined recent progress and current knowledge of the biochemical and physiological interactions between macro- and micro-mineral nutrients in plants and aimed to focus on the cross-talks between N, Pi, S, Zn, and Fe uptake and homeostasis in plants. More importantly, we further reviewed current studies on the molecular mechanisms underlying the cross-talks between N, Pi, S, Zn, and Fe homeostasis to better understand how these nutrient interactions affect the mineral uptake and signaling in plants. This review serves as a basis for further studies on multiple nutrient stress signaling in plants. Overall, the development of an integrative study of multiple nutrient signaling cross-talks in plants will be of important biological significance and crucial to sustainable agriculture.

“…In terms of significant relationships among minerals, K had positive correlation with Mn and negative with Zn/On the other hand, B and Cu were inversely related. The first association is in accordance with that mentioned by Fan et al [ 74 ] who reported this relationship among these elements in plants, but for these authors K and Zn had a positive association (whereas B and Cu did not show any relationship). In addition, Na and Mn showed a positive correlation, which would mean that there was a synergism effect between these two elements.…”

Nitrogen and phosphorus deficiencies alter primary and secondary metabolites of soybean roots

“…The plant ionome is tightly regulated by uptake, translocation, storage, and remobilization as plants aim to maintain their nutrient homeostasis (Courbet et al, 2019). Multiple cross-talks between macro-and micronutrients have been described previously (Fan et al, 2021). The phenomenon of interactions between N and P and also with other nutrients has been recognized, but the underlying mechanisms have not been completely understood.…”

Editorial: Nutrient Interactions in Plants

“…All these elements interact in a direct and/or indirect manner. In some cases, the deficiency or excess of one element can affect the uptake of other(s), thus conditioning their proper uptake and efficient utilization (Astolfi et al, 2021;Bernal and Kramer, 2021;Pavlovic et al, 2021;Yu et al;Zhou et al). For instance, S deficiency can limit Fe acquisition (Astolfi et al, 2021) while P deficiency can promote it (Figure 1; García et al).…”

“…It includes 5 reviews, 1 minireview, 1 perspective and 13 original research articles. Regarding the reviews; one is related to interactions between two essential elements, S and Fe (Astolfi et al, 2021); two are related to interactions between macro-and micro-nutrients (Fan et al, 2021;Kumar et al, 2021); and the other two are dedicated to interactions between beneficial elements, Si and Se, and essential ones (Pavlovic et al, 2021;Zhou et al). The minireview deals with the interaction between N and P in the development of root nodules and cluster roots (Pueyo et al, 2021).…”

“…It is important to note the interest of the interactions between essential and non-essential elements, since non-essential elements, like Na, can partially substitute for essential ones, like K (Mateus et al). Additionally, non-essential elements, like Si, can affect the homeostasis of essential elements (Pavlovic et al, 2021), and vice versa (Chaiwong et al;Zhou et al). A better knowledge of such interactions could aid in the improvement of some nutritional disorders and/or in the biofortification of some essential elements for humans and animals, like Se (Zhou et al).…”
