raphanus sativus/ニコチン

Infectious clones were generated from 17 new Korean radish isolates of Turnip mosaic virus (TuMV). Phylogenetic analysis indicated that all new isolates, and three previously characterized Korean radish isolates, belong to the basal-BR group (indicating that the pathotype can infect both

Freeze-etch observations of protoplasts isolated from tobacco (Nicotiana tabacum L.) mesophyll tissue and tomato (Lycopersicum esculentum Mill.) fruit locule tissue are described which clarify earlier observations (Burgess, J., Fleming, E.N., Planta 131, 173-178, 1976; Planta 133, 267-273, 1977),

Defensins are small positively charged, antimicrobial peptides (approximately 5 kDa in size) and some of them exhibit potent antifungal activity. We have cloned the complete cDNA containing an ORF of 243 bp of a defensin of mustard. The deduced amino acid sequence of the peptide showed more than 90%

The advantages of gene 'stacking' or 'pyramiding' are obvious in genetically modified (GM) crops, and several different multi-transgene-stacking methods are available. Using linker peptides for multiple gene transformation is considered to be a good method to meet a variety of needs. In our

Elicitins are small, secreted proteins produced by species of the plant-pathogenic oomycete Phytophthora. They induce hypersensitive cell death in most Nicotiana species and in some cultivars of Brassica rapa and Raphanus sativus. In this study, two true-breeding Fast Cycling B. rapa lines were

The activity of various plant peroxidases and the ability of their individual isoforms to bind chitin was studied. Some increase in peroxidase activity was observed in crude extracts in the presence of chitin. Activated peroxidases of some species fell in the fraction not sorbed on chitin and those

A novel cytoplasmic male-sterility (CMS) radish (Raphanus sativus L.) and its associated mitotype (DCGMS) were previously identified; however, no mtDNA fragments flanking the atp6 gene were found in the DCGMS mitotype. Unlike three other mitotypes in this study, a unique mtDNA organization,

In 2008, a bacterial blight was observed on Raphanus sativus in the Pfalz region in Germany. Disease was sporadic but severe when present within R. sativus fields, which resulted in unmarketable crops. Symptoms consisted of small, angular, water-soaked flecks that often were surrounded by chlorotic

The RsMYB1 transcription factor (TF) controls the regulation of anthocyanin in radishes (Raphanus sativus), and its overexpression in tobacco and petunias strongly enhances anthocyanin production. However, there are no data on the involvement of RsMYB1 in the mechanisms underlying abiotic stress

In 2014, we performed a nationwide survey in Korean radish fields to investigate the distribution and variability of Turnip mosaic virus (TuMV). Brassica rapa ssp. pekinensis sap-inoculated with three isolates of TuMV from infected radish tissue showed different symptom severities, whereas symptoms

Metabolism of [carbonyl-14C]nicotinamide was surveyed in various plant materials including the model plants, Arabidopsis thaliana, Oryza sativa and Lotus japonicus. In all plants studied, nicotinamide was used for the pyridine (nicotinamide adenine) nucleotide synthesis, probably after conversion to

A novel cDNA of phospholipid hydroperoxide glutathione peroxidase (PHGPx), which encodes a functional protein capable of complementing the yeast PHGHX-deletion mutant, was recently discovered in radish (Raphanus sativus) and designated as RsPHGPx [Yang X-D, Li W-J, Liu J-Y (2005) Biochim Biophys

The transcriptional patterns of mitochondrial respiratory related genes were investigated in cytoplasmic male-sterile and fertile maintainer lines of stem mustard, Brassica juncea. There were numerous differences in nad2 (subunit 2 of NADH dehydrogenase) between stem mustard CMS and its maintainer

Radish seeds have previously been shown to contain two homologous, 5-kD cysteine-rich proteins designated Raphanus sativus-antifungal protein 1 (Rs-AFP1) and Rs-AFP2, both of which exhibit potent antifungal activity in vitro. We now demonstrate that these proteins are located in the cell wall and

Cadmium (Cd) is an environmental pollutant that causes health hazard to living organisms. Melatonin (MT) has emerged as a ubiquitous pleiotropic molecule capable of coordinating heavy metal (HM) stresses in plants. However, it remains unclear how melatonin mediates Cd homeostasis and detoxification
