متن کاملSelenium in Higher Plants.
Plants vary considerably in their physiological response to selenium (Se). Some plant species growing on seleniferous soils are Se tolerant and accumulate very high concentrations of Se (Se accumulators), but most plants are Se nonaccumulators and are Se-sensitive. This review summarizes knowledge of the physiology and biochemistry of both types of plants, particularly with regard to Se uptake ...
متن کاملDPX 1840-induced Organogenesis in Xanthi-nc Tobacco Plants.
The synthetic growth regulant DPX 1840 (3,3a-dihydro-2-(p-methoxyphenyl)-8H-pyrazolo[5, 1-a]isoindol-8-one) induced callus growth and subsequent tissue differentiation on cut surfaces of decapitated Xanthi-nc tobacco plants (Nicotiana tabacum). Callus formation and organogenesis induced by DPX 1840 depended on the presence of leaves. The adventitious meristems developed into either vegetative o...
متن کاملHigher Plants
Contamination with 2,4,6-trinitrotoluene (TNT) is widespread at sites of past munitions manufacture. It is moderately toxic to plants and highly toxic to some animals. Some aquatic plant species have been observed to promote degradation of TNT. The degradative activity is associated with the root systems but products are found in the surrounding medium. We have examined a range of sixteen gener...
متن کاملPantothenate biosynthesis in higher plants.
Pantothenate (vitamin B5) is a water-soluble vitamin essential for the synthesis of CoA and ACP (acyl-carrier protein, cofactors in energy yielding reactions including carbohydrate metabolism and fatty acid synthesis. Pantothenate is synthesized de novo by plants and micro-organisms; however, animals obtain the vitamin through their diet. Utilizing our knowledge of the pathway in Escherichia co...
