Induction of Phenolic Compounds is Affected by Boron Supply in Marshmallow (Althaea officinalis L. ) Cells
Boron (B) is a non-metal micronutrient which is essential for plants growth and development. Formation of boron complex with cell wall matrix and phenolic compounds is a definite influence of boron in physiological process. It has been suggested that B-toxicity and deficiency may induce excess production of reactive oxygen species thereby promote defense responses by antioxidant enzymes or non-...
متن کاملChanges of major wall polysaccharides and glycoproteins of tobacco cells in response to excess boron
Effects of excess concentrations of boron on major cell wall components of tobacco cells(Nicotiana tabacum L. cv. Burley 21) were studied. Pectin, xyloglucan, hydroxyproline-richglycoproteins (extensin), and arabinogalactan proteins were characterized. Results showedthat increased boron supply resulted in significant decrease in cell and cell wall dry weights.Also, high concentrations of boron ...
متن کاملBoron effects on wall polysaccharide composition of marshmallow cells
Marshmallow is a medicinal plant containing mucilage polysaccharides and various phenolic acids. Boron (B) is an essential micronutrient whose necessity for plant growth and development has been attributed to its role in cell wall pectin network and maintenance of integrity and performance of membranes. The present study was aimed to investigate the effects of different concentrations of B (0.0...
متن کاملRole of Boron in Vascular Plants and Response Mechanisms to Boron Stresses
To date, the primordial function of boron is its structural role in the cell wall through stabilization of molecules containing cis-diol groups (borate esters with apiose residues of rhamnogalacturonan II). Nonetheless, boron is a micronutrient also involved in a great variety of physiological processes in vascular plants. However the mechanisms underlying the various metabolic disorders caused...
