Development and characterization of microsatellite primers in Geranium carolinianum (Geraniaceae) with 454 sequencing1
UNLABELLED PREMISE OF THE STUDY Microsatellite primers were developed for Geranium carolinanum, a North American winter annual herb, for use in population genetic analyses. • METHODS AND RESULTS Genomic DNA enriched for repeat-containing fragments was sequenced on the Roche 454 Titanium platform, resulting in 470 primer pairs developed from 1115 microsatellite-containing sequences. A subse...
متن کاملAnti-hepatitis B virus activities of Geranium carolinianum L. extracts and identification of the active components.
The ethanol extract of Geranium carolinianum L., a domestic plant grown in China, was subjected to sequential extractions with different organic solvents. The extracts were assayed for anti-hepatitis B virus (HBV) activities. The ethyl acetate fraction was found to contain the highest level of anti-HBV activity. In order to identify the active ingredients, the ethyl acetate fraction was further...
متن کاملQuantitative analysis of the thermal requirements for stepwise physical dormancy-break in seeds of the winter annual Geranium carolinianum (Geraniaceae).
BACKGROUND AND AIMS Physical dormancy (PY)-break in some annual plant species is a two-step process controlled by two different temperature and/or moisture regimes. The thermal time model has been used to quantify PY-break in several species of Fabaceae, but not to describe stepwise PY-break. The primary aims of this study were to quantify the thermal requirement for sensitivity induction by de...
متن کاملChromatographic Fingerprint and the Simultaneous Determination of Five Bioactive Components of Geranium carolinianum L. Water Extract by High Performance Liquid Chromatography
A simple and sensitive HPLC method has been developed in combination with fingerprint analysis and simultaneous determination of five markers, namely gallic acid, corilagin, methyl brevifolincarboxylate, ellagic acid and rutin for evaluation and quality control of Geranium carolinianum L. water extract. Extraction methods were optimized by comparing the hydrolysis efficiency of geraniin, a majo...
متن کاملVirus Diseases of Geranium
Several diseases of geraniums (Pelargonium species) are caused by viruses. The economic losses caused by these diseases are difficult to assess since infected plants are often symptomless and because both the cultivar and the environment in which the plants are growing can greatly influence the severity of the symptoms. The problem is compounded by the diverse sources of stock plants and the fa...
