High impact information on Silene

• Here we show that a gene encoding a male-specific protein is linked to the X chromosome in the dioecious plant Silene latifolia, and that it has a degenerate homologue in the non-pairing region of the Y chromosome [1].
• To determine whether MADS box genes also play a role in differentiation of the sexes in dioecious plants, we isolated cDNAs (SLM1 to SLM5, for Silene latifolia MADS) with MADS box homology from transcripts of male flower buds of the model dioecious species white campion and compared their expression in developing female and male flowers [2].
• Remarkably, we found nine distinct cytochrome b sequence haplotypes in the gynodioecious alpine plant Silene acaulis, with two or more haplotypes coexisting locally in each of three sampled regions [3].
• Evolution of a RNA polymerase gene family in Silene (Caryophyllaceae)-incomplete concerted evolution and topological congruence among paralogues [4].
• Addition of cyclopropyl alkynes to a Brook silene: definitive evidence for a biradical intermediate [5].

Biological context of Silene

• A cDNA clone (pFD1) derived from Silene pratensis ferredoxin mRNA was selected from a cDNA-library using the hybrid released translation technique [6].
• Here, we show that indels in three cpDNA intergenic spacers and one cpDNA intron for two species of Silene evolve at slightly higher rates than base pair substitutions [7].
• Sex determination in dioecious Silene latifolia. Effects of the Y chromosome and the parasitic smut fungus (Ustilago violacea) on gene expression during flower development [8].
• Localization of male-specifically expressed MROS genes of Silene latifolia by PCR on flow-sorted sex chromosomes and autosomes [9].
• Life-cycle phases of a zinc- and cadmium-resistant ecotype of Silene vulgaris in risk assessment of polymetallic mine soils [10].

Associations of Silene with chemical compounds

• The mechanism of 1,2-addition of disilene and silene. 1. Water and alcohol addition [11].
• In the presence of alkyne, diarylalkyne reacted with silene coordinated with zirconium to give silazirconacyclopentene 8 [12].
• Synthesis of a silene from 1,1-dilithiosilole and 2-adamantanone [13].
• Based on the relative positions of the phenyl and methoxy substituents within the seven-membered ring of the silacycloheptenes and the known behavior of the alkyne probes under both radical and ionic conditions, it was concluded that a biradical intermediate was formed during the addition of alkynes 1b-c to silene 10 [5].
• On the basis of the HOMO, LUMO, and Laplacian of electron distribution of disilene and silene, several mechanisms have been assumed, depending on the substrate (disilene, substituted disilene, silene, or ethene) and the reagent (water, methanol, or trifluoromethanol) [11].

Gene context of Silene

• Here we demonstrated fucosyltransferase activity (FucT) in Silene alba cells and tissues [14].
• G-overhangs were observed in Silene seeds and leaves, tissues that lack telomerase activity [15].
• Silene latifolia and sorghum telomerases constituted class III enzymes that elongated non-telomeric DNA primers by annealing them at alternative sites on the RNA template [16].
• Expression of the floral B-function gene SLM2 in female flowers of Silene latifolia infected with the smut fungus Microbotryum violaceum [17].
• Although Permagum Low, Silene Wash, and Xantopren Blue scored high in one of the two tests, none of these materials could compare to Reprosil Light within the context described herein [18].

Analytical, diagnostic and therapeutic context of Silene

• Metabolomic analysis of the consequences of cadmium exposure in Silene cucubalus cell cultures via 1H NMR spectroscopy and chemometrics [19].
• The peptide-N4-(N-acetylglucosaminyl) asparagine amidase (PNGase Se) earlier described [Lhernould S., Karamanos Y., Bourgerie S., Strecker G., Julien R., Morvan H. (1992) Glycoconjugate J 9:191-97] was partially purified from cultured Silene alba cells using affinity chromatography [20].
• The effect of oral administration of a 50% ethanol extract of Silene aprica (SA) on acute liver injury was examined in rats intoxicated with carbon tetrachloride (CCl4) and acetaminophen [21].
