Meta-analysis of the role of zinc in coordinating absorption of mineral elements in wheat seedlings

Abstract

Background Zinc (Zn) is an important nutrient for human beings, which is also an essential micronutrient for crop growth. This study investigated the role of Zn in coordinating the mineral elements absorption in modern wheat (Triticum aestivum L.) cultivars with a new developed method. Results A method was developed, and showed a robust capability to simultaneously investigate seven mineral elements uptake in wheat seedling. With this method, we found low Zn supply (< 1 μM) promoted the absorption of potassium (K), magnesium (Mg) and manganese (Mn) in wheat seedling, while high Zn supply (> 1 μM) significantly inhibited the absorption of these elements. Cultivars with the green genes (Rht-B1b and Rht-D1b) showed a higher uptake capability on ammonium (NH4+), and cultivars with Rht-B1b allele can uptake more phosphors (P), K, calcium (Ca), Mn and Zn compared to cultivars with Rht-D1b. Further analysis indicated higher uptake capability of NH4+ in cultivars contained Rhts was independent of Zn. Conclusion The key role of Zn in coordinating for mineral elements absorption was identified in modern wheat cultivars, providing the reference for Zn application in wheat. Meanwhile, this study provides a robust method for quantifying the absorption of mineral elements, which may be adopted into the broadly investigations on the coordinated nutrients absorption of plant.

Selenium-Containing Organic Fertilizer Application Affects Yield, Quality, and Distribution of Selenium in Wheat

“…For example, Ca, as a medium-level element in plants, plays an important role in maintaining the structural stability of the cell wall [ 41 ]. Zinc, as a trace element, is involved in the conversion of carbohydrates and the synthesis of proteins [ 42 ]. The application of Se fertilization might influence the mineral nutrients in crop tissues, and the degree of influence was found to vary with Se concentration, Se application method, crop variety, crop organ, etc.…”

The Mechanism of Manganese Ferrite Nanomaterials Promoting Drought Resistance in Rice

“…Once taken up by plants, NMs could be transported and accumulated in different parts, interacting with various cellular components and further impacting plant physiology and metabolism [16]. Fe, a vital element for photosynthesis, facilitates electron transfer processes in Photosystem II, and a series of enzymes involved in photosynthesis rely on Mg as a cofactor [28], which surely strengthens photosynthesis (Figure 2). Additionally, NMs were proven to be more efficient than their equivalent ion control systems because of their unique properties [29].…”
