Physical and physiological dormancy in black henbane (Hyoscyamus niger L.) seeds

Effect of sulfur on nitrate reductase and ATP sulfurylase Activities in groundnut (Arachis hypogea L.)
Journal of Plant Biology - Tập 49 - Trang 513-517 - 2006
Field experiments were conducted to determine the effect of sulfur (S) and Nitrogen (N) on nitrate reductase (NR) and ATP-sulfurylase activities in groundnut cultivars (Arachis hypogea L. cv. Ambar and Kaushal). Two combinations of S (in kg ha-1): OS (-S) and 20S (+S) were used with 20 kg ha-1 N. The application of S enhanced the NR and ATP-sulfurylase activities in both the cultivars at all the g......
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......
TsMIP6 enhances the tolerance of transgenic rice to salt stress and interacts with target proteins
Journal of Plant Biology - Tập 58 - Trang 285-292 - 2015
Aquaporins (AQPs), a large family of channel proteins in plants, play an important role in regulating the balance of osmotic potential in cells. We isolated an AQP gene, TsMIP6, from the halophyte Thellungiella salsuginea and functionally characterized it in transgenic rice (Oryza sativa). This gene belongs to a subfamily of tonoplast intrinsic proteins and is localized at the plasma membrane. Rea......
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......
BrRH37, a Cabbage (Brassica rapa) DEAD-Box RNA Helicase, Confers Drought Tolerance and ABA Response in Transgenic Arabidopsis Plants
Journal of Plant Biology - Tập 64 - Trang 327-336 - 2021
RNA helicases (RHs) are cellular proteins that help in the regulation of post-transcriptional mRNA metabolism, which is vital for the response of crops to abiotic stresses. In this study, we determined the functional role of a cabbage (Brassica rapa) DEAD-box RH, BrRH37, in abiotic stress and abscisic acid (ABA) responses using transgenic Arabidopsis plants. Although BrRH37 contains a putative chl......
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......
