Abstract
One of the most important components in achieving increased crop productivity is a balanced supply of nec
essary 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 bind
ing component in the cell wall, and as a result, it maintains membrane integrity, the indole acetic acid path
way, 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 manage
ment etc.
