Gene flow from genetically modified (GM) crops to non-GM cultivars or weedy relatives may lead to the development of more aggressive weeds. We quantified the amount of gene flow from herbicide-tolerant GM rice (Protox GM, derived from the cultivar Dongjin) to three cultivars (Dongjin, Aranghyangchal and Hwaseong) and a weedy rice line. Gene flow frequency(More)
There is global concern about the environmental consequences associated with transgenic crops. Their effects on the soil ecosystem are of special interest when assessing ecological safety and integrity. Although many efforts have been made to develop crops genetically modified to have resistance to protoporphyrin oxidase (PPO)-inhibiting herbicides, little(More)
Fibrous roots of sweetpotato (Ipomoea batatas (L.) Lam.) usually develop into both pencil and storage roots. To understand protein function in root development, a proteomic analysis was conducted on the pencil and storage roots of the light orange-fleshed sweetpotato cultivar, Yulmi. Two-dimensional gel electrophoresis showed that expression of 30 protein(More)
Sorgoleone, found in the root exudates of sorghum [(Sorghum bicolor (L.) Moench], has been a subject of continued research. Sorgoleone production in grain sorghum roots was investigated under different growth conditions. Methanol was the most effective solvent for extracting sorgoleone from grain sorghum roots. Sorgoleone production is high in young(More)
DNA sequence analysis of the psbA gene encoding the D1 protein of photosystem II (PS II), the target site of PS II-inhibiting herbicides, identified a point mutation (Asn266 to Thr) in a bromoxynil-resistant Senecio vulgaris L. population collected from peppermint fields in Oregon. Although this mutation has been previously reported in Synechocystis, this(More)
This study compares the differences in proteomes expressed in tuberous roots of a light orange-fleshed sweetpotato (Ipomoea batatas (L.) Lam. cultivar Yulmi) and a purple-fleshed sweetpotato cultivar (Shinjami). More than 370 protein spots were reproducibly detected by two-dimensional gel electrophoresis, in which 35 spots were up-regulated (Yulmi vs.(More)
BACKGROUND There is growing demand for the development of alternative pest control agents that are effective as well as non-toxic to human health and the environment. Plant protection products derived from plant extracts are an eco-friendly alternative to synthetic pesticides. The aim of this study was to identify larvicidal compounds isolated from a(More)
The Cucumber mosaic virus coat protein (CMV-CP) gene-transgenic pepper lines exhibit high tolerance to Cucumber mosaic virus (CMV) strains. In this study, E7, one of the CMVP0-CP transgenic chili pepper events selected by screening was further characterized. Southern blotting and inverse PCR analysis revealed that the E7 event contains a single copy of the(More)
Zoysia grass (Zoysia japonica Steud.) is a commercially valuable turfgrass that is popularly cultivated for use in sports and recreational environments. A field study was conducted in 2013 to evaluate the effects of transgenic herbicide-resistant Zoysia grasses in combination with the herbicide glufosinate on microbial communities. We investigated(More)
