Functions of boron in plant roots: Current insights

Abstract

One of the most important components in achieving increased crop productivity is a balanced supply of necessary macro- and micronutrients. Among the various nutrients Boron (B) is recognised as a vital nutrient for the plant's life. however, inadequate availability of B can affect root development, nitrogen absorption, the integrity and function of cell walls and ultimately reduce the crop yield. Over 90 % of B in plants is found in cell wall, signifying its relevance in the growth and development of the root system. Since B is crucial for indispensable plant processes, it is a necessary constituent of rhamnogalacturonan II (RG-II), acting as a binding component in the cell wall, and as a result, it maintains membrane integrity, the indole acetic acid pathway, and cell wall synthesis. Therefore, this review aimed to assemble the novel information's of the function of boron in roots of the plant, deficiency symptoms, and the mechanisms of abiotic stresses management etc.
