The research team led by Prof. ZHENG Shao-Jian from the Zhejiang University College of Life Sciencespublished a research article entitled “A Transcription Factor STOP1-Centered Pathway Coordinates Ammonium and Phosphate Acquisition in Arabidopsis” in the journal Molecular Plant on June 30, 2021 (doi: /10.1016/j.molp.2021.06.024). This study uncovers the molecular bases of low phosphorus-induced secretion of organic acids and the mechanisms for the coordination of phosphorous and nitrogen nutrition in plants, thus providing new insights into the utilization of insoluble phosphorus in soil by breeding new nutrient-efficient varieties and developing targeted fertilization techniques.
Phosphorus is an essential macronutrient for crop growth and development, but the efficacy of phosphorus in soil is often very low. Accordingly, agricultural production requires a substantial quantity of inorganic phosphate (Pi) fertilizers. However, only 20-30% of Pi is taken up b

Trees are by far the tallest organisms on Earth. Height growth is made possible by a specialized vascular system that conducts water from the roots to the leaves with high efficiency, while simultaneously providing stability. The so-called xylem, also known as wood, is a network of hollow cells with extremely strong cell walls that reinforce the cells against the mechanical conflicts arising from growing tall. These walls wrap around the cells in filigree band and spiral patterns. So far, it is only partly known, how these patterns are created. Scientists from the Max Planck Institute for Molecular Plant Physiology in Golm/Potsdam and from Wageningen University and their colleagues study the formation of such reinforced and patterned cell walls.
