Boron in plants: deficiency and toxicity.
Boron (B) is an essential nutrient for normal growth of higher plants, and B availability in soil and irrigation water is an important determinant of agricultural production. 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...
متن کاملModeling Vegetative Stage Response of Canola (Brassica napus L.) to Combined Salinity and Boron tresses
Boron (B) is essential to growth at low concentrations and limits growth and yield when in excess. Little is known regarding plant response to excess B and salinity occurring simultaneously. In this study, two models of Leibig-Sprengel (LS) and Mitscherlich-Baule (MB), originally proposed to explain plant response to nutrients only, were modified to evaluate canola yield response to combined le...
متن کامل“Trilongins” Offer Insight into Mold Toxicity
Mold contamination inside buildings is a widespread occurrence that can cause a range of adverse health effects in certain people. But with tens of thousands of mold species and many mechanisms through which they may cause harm, much remains unknown about this realm of environmental exposures. Investigators now report that one mold, Trichoderma longibrachiatum, does some of its damage through a...
متن کاملAntioxidant responses of chickpea plants subjected to boron toxicity.
This study investigated oxidative stress and the antioxidant response to boron (B) of chickpea cultivars differing in their tolerance to drought. Three-week-old chickpea seedlings were subjected to 0.05 (control), 1.6 or 6.4 mm B in the form of boric acid (H(3)BO(3)) for 7 days. At the end of the treatment period, shoot length, dry weight, chlorophyll fluorescence, B concentration, malondialdeh...
متن کاملInsights into the Mechanisms Underlying Boron Homeostasis in Plants
Boron is an essential element for plants but is toxic in excess. Therefore, plants must adapt to both limiting and excess boron conditions for normal growth. Boron transport in plants is primarily based on three transport mechanisms across the plasma membrane: passive diffusion of boric acid, facilitated diffusion of boric acid via channels, and export of borate anion via transporters. Under bo...
