Molecules, Vol. 23, Pages 345: Weed Suppressing Potential and Isolation of Potent Plant Growth Inhibitors from Castanea crenata Sieb. et Zucc
This study isolated, determined, and quantified plant growth inhibitors in Japanese chestnut (Castanea crenata Sieb. et Zucc), a deciduous species native to Japan and Korea. In laboratory assays, C. crenata leaves showed strong inhibition on germination and seedling growth of Echinochloa crus-galli (barnyardgrass), Lactuca sativa (lettuce), and Raphanus sativus (radish). Laboratory and greenhouse trials showed that leaves of C. crenata appeared as a promising material to manage weeds, especially the dicot weeds. By GC-MS and HPLC analyses, gallic, protocatechuic, p-hydroxybenzoic, caffeic, ferulic, ellagic, and cinnamic ac...

Fodder radish cake (Raphanus sativus L.) as an alternative biomass for the production of cellulases and xylanases in solid-state cultivation
In this study, FR cake (FRC) was evaluated as carbon and nitrogen source for the production of cellulases and xylanases using Penicillium echinulatum S1M29 during solid-state cultivation. It was determined that it is possible to partially replace wheat bran (WB) by FRC, resulting in 24.22 ± 0.25U/g Filter Paper Activity (144 hours), 210.5 ± 5.8U/g endoglucanase activity (144 hours), 22.62 ± 0.01U/g (-glucosidase activity (96 hours) and 784.7 ± 70.19U/g xylanase activity (120 hours). These values are equal or higher than the enzymatic activity obtained using WB. These results may contribute to the reduction of the cost ...

Traditional herbal medicine-derived sulforaphene promotes mitophagic cell death in lymphoma cells through CRM1-mediated p62/SQSTM1 accumulation and AMPK activation.
Abstract
Sulforaphene (LFS-01) is the major chemical constituent of Raphanus sativus, a medicinal herb used for over a thousand years in traditional Chinese medicine. Here we identified that LFS-01 can selectively eradicate lymphoma cells while sparing normal lymphocytes by triggering concomitant mitophagy and apoptosis. We demonstrated that LFS-01 can retain Nrf2 in the nucleus by covalently modulating CRM1 and consequently upregulate p62/SQSTM1, an essential structural component of the autophagosomes during mitophagic process. We found that LFS-01 treatment also stimulated AMPK and thereby inhibited the ...

Green silver nanoparticles from novel Brassicaceae cultivars with enhanced antimicrobial potential than earlier reported Brassicaceae members
Publication date: Available online 12 January 2018 Source:Journal of Trace Elements in Medicine and Biology Author(s): Amarjeet Singh, Bhavana Sharma, Renu Deswal In the present study, we report perhaps for the first time the use of novel varieties of Brassica oleracea var. botrytis and Raphanus sativus as potential bioreductant to synthesize highly stable silver nanoparticles (AgNPs, no aggregation observed for six months), which is a significant finding as plant extract-directed Ag NPs are intrinsically unstable and tend to aggregate. The reduction of Ag+ to Ag0 nanostructures was confirmed using UV–Visible spectr...

Complete genomic sequence of Raphanus sativus cryptic virus 4 (RsCV4), a novel alphapartitivirus from radish
AbstractThe present work reports the discovery and complete genome sequencing of a virus from symptomless radish seedlings, classifiable as a novel member of the genusAlphapartitivirus, familyPartitiviridae. Total RNA extracted from germinating seedlings was sequenced using Illumina technology. Bioinformatic analysis of the RNA-seq data revealed two contigs representing the near full-length genomic sequences of two genomic RNAs representing a new virus. Analysis of the genome sequence (excluding the polyA tail, RNA1: 1976 nt and RNA2: 1751 nt, respectively) showed a genomic organization typical of viruses classed within th...

Humic acids decrease uptake and distribution of trace metals, but not the growth of radish exposed to cadmium toxicity.
Abstract
Naturally-occurring highly-complexed and polymerised organics such as humic acids (HA), due to their large negative charge, play a crucial role in biogeochemistry of trace metals (TM). Toxic (Cd) as well as essential (Zn, Cu, Mn) TM bind strongly to HA, but how these organo-metalic forms influence metal uptake by plants is poorly understood. A solution culture study was conducted to characterize the effects of different concentrations of HA (0-225mg/L) on the growth and element uptake/distribution in roots, shoots and hypocotyls of radish (Raphanus sativus L.) exposed to Cd (0.5mg/L) contamination...

Responses of radish (Raphanus sativus) to drought stress
Abstract
With this study the effects of water deficit on radish growth, dry mass production and partitioning, source–sink relations, physiological responses and accumulation of secondary metabolites in storage roots and leaves have been investigated. Three water stress treatments were applied: (Control) 100% of water holding capacity (WHC), (WS50) 50% of WHC, (WS30) 30% of WHC. Water stress was effectively acquired starting from 287 growing degree days (GDD) as demonstrated by the lower values of relative water content (RWC), higher leaf temperature and NIR‐based water indices values in water stressed conditions. Water...

Deciphering physio-biochemical, yield, and nutritional quality attributes of water-stressed radish (Raphanus sativus L.) plants grown from Zn-Lys primed seeds.
Abstract
Water shortage appears to be expedited under the current climate change scenario worldwide. The present work was aimed to investigate the effects of zinc-chelated lysine (Zn-Lys) on germination and yield of water stressed radish plants. The research was comprised of two studies where the effect of Zn-Lys seed priming on germination attributes under PEG-induced water stress was investigated in the first experiment. In the second experiment, growth, physio-biochemical, and yield responses of water-stressed radish plants raised from Zn-Lys primed seeds were recorded. The seeds pre-conditioned with 0,...

Ammonium haloacetates - An alternative to glyphosate?
This study shows the design, synthesis and evaluation of eco(phyto)toxic and herbicidal activities of quaternary ammonium salts (QASs), derived from haloacetic acids, in context of the search for safer alternatives to the commonly used herbicide, N-(phosphonomethyl)glycine (glyphosate). The structure of the investigated QASs refers to the heteroatom sequence in the anion of glyphosate in which the (P-C)-N nitrogen atom was replaced by one or more halogens (F, Cl). The ecotoxicity of the synthesized QASs was tested against luminescent marine bacteria Vibrio fischeri (Microtox® test) and the crustaceans Heterocypris incongr...

Is repeated exposure the holy grail for increasing children's vegetable intake? Lessons learned from a Dutch childcare intervention using various vegetable preparations.
Abstract
Children's failure to eat enough vegetables highlights the need for effective interventions encouraging this behaviour. The aim of this study was to investigate the effect of repeated exposure to three a priori unfamiliar vegetables, each prepared in two ways, on children's vegetable acceptance in a childcare setting. Two hundred fifty children (mean age 25 months; 57% boys) participated in a pre-test and a post-test, where they were offered pumpkin, courgette, and white radish. The intervention group (N = 125) participated in a 5-month exposure period, where they were exposed repeatedly (∼12x...

4-Methylthio-3-butenyl isothiocyanate mediates nuclear factor (erythroid-derived 2)-like 2 activation by regulating reactive oxygen species production in human esophageal epithelial cells.
Abstract
4-Methylthio-3-butenyl isothiocyanate (MTBITC) extracted from daikon (Raphanus sativus), which shows antimutagenicity, may have applications as an effective chemopreventive agent in several cancers; however, few reports have described the associated mechanisms. We investigated whether MTBITC induced cytoprotective genes, including phase II enzymes, in Het-1A human esophageal epithelial cells. HMOX1, NQO1, and GCLC mRNA levels and nuclear factor (erythroid-derived 2)-like 2 (Nrf2) protein levels were increased in Het-1A cells exposed to 10 μM MTBITC. Reactive oxygen species (ROS) tended to increas...
