Exclusive cytosolic localization and broad tRNASer specificity of Arabidopsis thaliana seryl-tRNA synthetase
Journal of Plant Biology - Tập 59 - Trang 44-54 - 2016
Aminoacyl-tRNA synthetases (aaRSs) decipher the genetic code, covalently linking amino acids to cognate tRNAs, thus preparing substrates for the process of translation. Although aaRSs funtion primarily in translation and are localized in cytosol, mitochondria and chloroplasts there are many reports on their additional functions and subcellular destinations beyond translation. However, data on plan......
Celastrol, produced by Tripterygium wilfordii Hook F. enhances defense response in cucumber seedlings against diverse environmental stresses
Journal of Plant Biology - Tập 60 - Trang 82-92 - 2017
Celastrol is an active triterpenoid compound isolated from Tripterygium wilfordii Hook F.. Many reports have highlighted that celastrol is an effective, safe and desirable approach to the treatment of cancers. However, their biological function during environmental stresses in plants is rarely reported. In the present study, the effects of celastrol on the tolerance against high light (HL), polyet......
Monitoring the occurrence of genetically modified soybean and maize around cultivated fields and at a grain receiving port in Korea
Journal of Plant Biology - Tập 49 - Trang 218-223 - 2006
Increased imports of genetically modified (CM) soybean and maize might cause genetic contamination of those crops that are conventionally bred, as well as wild soybeans within Korea. Leaves of maize and both cultivated and wild soybeans were sampled in and near rural fields to detect the presence of transgenes. Roadsides around a major grain port in Incheon were also surveyed to monitor the occurr......
Characterization and light-induced expression of theS-adenosylmethionine decarboxylase gene fromIpomoea nil
Journal of Plant Biology - Tập 44 - Trang 111-117 - 2001
We screened a genomic library of Japanese morning glory(Ipomoea nil) and isolated theMGSDCgi clone (GenBank Accession Number U64927). The genomic clone comprised four exons and three introns.MCSDCgi contained a 660-bp 5′-untranslated region (UTR), a 1089-bp coding region of 362 amino acids, and a 209-bp 3′-UTR. A TATA box sequence (TATATAA) was found at position -29. The transcript leader of thisS......
Knock-down of OsLOX by RNA interference leads to improved seed viability in rice
Journal of Plant Biology - Tập 58 - Trang 293-302 - 2015
Previous work found that lipoxygenases were key enzymes in lipid peroxidation, which causes grain deterioration during storage. In order to obtain better seed viability in rice, 10 marker-free knock-down lines were obtained in the progeny of endogenous OsLOX knock-down mutations caused by the RNAi technology. After artificial accelerated aging, there were four types of knock-down lines with higher......
Decadal Succession Process in Five Forest Types in Cool-Temperate Odaesan National Park
Journal of Plant Biology - - Trang 1-15 - 2023
The succession process in terms of species composition and stand structure was directly tracked for 10 years in permanent plots of five Korean cool-temperate forests having different stand ages and topography: Pinus-Quercus forest (PQ), Quercus-Tilia forest (QT), Broadleaved-Abies mixed forest (BA), Populus-Salix forest (PS), and subalpine forest (SA). Although the 10-year change in mature forests......
Apple RING finger E3 ubiquitin ligase MdMIEL1 negatively regulates salt and oxidative stresses tolerance
Journal of Plant Biology - Tập 60 - Trang 137-145 - 2017
RING-finger-containing E3 ubiquitin ligases play important roles in plant response to biotic and abiotoc stresses. In this study, through homology analysis, a Malus× domestica MYB30-Interacting E3 Ligase 1 gene, MdMIEL1, was identified and subsequently cloned from apple ‘Gala’ (Malus×domestica). MdMIEL1 contained a zinc finger domain close to N-terminus and a RING finger domain close to Cterminus.......
Diversified mechanisms for regulating flowering time in a short-day plant rice

Overexpressing a novel RING-H2 finger protein gene, OsRHP1, enhances drought and salt tolerance in rice (Oryza sativa L.)
Journal of Plant Biology - Tập 57 Số 6 - Trang 357-365 - 2014
RING (really interesting new gene) zinc-finger proteins have important regulatory roles in the development of a variety of organisms. In the present report, a full length cDNA encoding a novel RING-H2 finger protein from rice, designated as OsRHP1, was isolated and characterized. OsRHP1 encodes a small protein (167 amino acids) with two N-terminal trans-membrane domains and a canonical RING-H2 zin......
Contrasted Responses to Root Hypoxia in Tomato Fruit at Two Stages of Development
Journal of Plant Biology - Tập 54 - Trang 15-22 - 2010
The biochemical consequences of root hypoxia have been documented in many sink organs, but not extensively in fruit. Therefore, in the present study, the response to root hypoxia in tomato fruit (Solanum lycopersicum L.) was investigated at two developmental stages, during the cell division and the cell expansion phases. Our results showed that in dividing fruit, root hypoxia caused an exhaustion ......
