Plant Physiol. Absence of the element is shown to affect nucleic acid and carbohydrate metabolism, and the relationship between boron, auxin and phenolic compounds is discussed. Vol. The 4Rs ... Boron is thought to play important roles in cell wall synthesis and sugar transport. Boron toxicity in plants is a relatively common issue in dry areas where soil boron levels are high. Boron in Plants: Deficiency and Toxicity Juan J. Camacho ... To date, a primordial function of B is undoubtedly its structural role in the cell wall; however, there is increasing evidence for a possible role of B in other processes such as the maintenance of plasma membrane function and several metabolic pathways. The only defined physiological role of boron in plants is as a cross-linking molecule involving reversible covalent bonds with cis-diols on either side of borate. Different plants need different amounts of boron, but for the most part, boron is not easily transported within the plants. Boron also plays roles in formation of sugar complexes for translocation within plants, and in the formation of proteins. Possible role of boron in transvacuolar cytoplasmic strands and cell-to-wall adhesion. One of the important functions of boron in plant nutrition is its role in fostering pollen growth and development, which is important in seed set and the resulting fruit, nut and grain production. Read on to learn more about diagnosing and treating low boron levels in cannabis plants. The Role of Boron in the Translocation of Organic Compounds in Plants. Boric acid (16.5%boron), borax (11.3% boron) or SoluBor (20.5% boron) can be applied to soils to correct boron deficiency. Boron stabilizes calcium in the cell wall and acts in synergy with calcium to improve plant resistance to disease, pest and environmental stresses. Up to 90% of a plant’s total boron content is found in its cell walls. The demand for boron in vegetables is higher. There are increasing evidences of this nutrient showing a variety of pleiotropic effects, ranging from anti-inflammatory and antioxidant effects to … Tweet Widget; Facebook Like; Google Plus One; Jump to section. [PMC free article ] Gauch HG, Wadleigh CH. In plants, boron has important roles in expanding organs, for this reason, the symptoms of boron deficiency can be mainly observed in expanding organs. Because it is a necessary component of plant cells, it has an antioxidant function and plays a vital role in plant reproduction, increasing tomato yield, and quality.
