Soil contamination, such as heavy metals and benzene compounds, is a widespread problem on military installations. It is important to be able to determine the effects of soil contamination before any adverse effects appear in organisms in surrounding areas. We examined gene expression in Arabidopsis
In a process called phytoremediation, plants can be used to extract, detoxify, and/or sequester toxic pollutants from soil, water, and air. Phytoremediation may become an essential tool in cleaning the environment and reducing human and animal exposure to potential carcinogens and other toxins.
Benzoates are a class of natural products containing compounds of industrial and strategic importance. In plants, the compounds exist in free form and as conjugates to a wide range of other metabolites such as glucose, which can be attached to the carboxyl group or to specific hydroxyl groups on the
This study identified the effect of salicylic acid on degradation of isoproturon in Arabidopsis. Three T-DNA insertion mutant lines pal1-1, pal1-2 and eps1-1 defective in salicylic acid synthesis were tested, which showed higher isoproturon accumulation and toxic symptom in the mutants. When treated
A pyrimidine-pyrimidone (6-4) photoproduct and a cyclobutane pyrimidine dimer (CPD) are major DNA lesions induced by ultraviolet irradiation, and (6-4) photolyase, an enzyme with flavin adenine dinucleotide (FAD) as a cofactor, repairs the former specifically by light illumination. We investigated
Phospholipid:diacylglycerol acyltransferase (PDAT) catalyzes the acyl-CoA-independent triacylglycerol (TAG) biosynthesis in plants and oleaginous microorganisms and thus is a key target in lipid research. The conventional in vitro PDAT activity assay involves the use of radiolabeled substrates,
