We have developed improved procedures for recovery of haploid and doubled haploid (DH) melon plants, using hybrids derived from crosses of lines with multiple virus resistance. Seeds formed after pollination with irradiated pollen were cultured in liquid medium for 10 days before excision of the embryos for further culture. This made it easier to identify(More)
An approach of combining flow cytometry (FCM) analysis with morphological and chemical profiling was used to assess the genetic stability and bioactive compound diversity in a Scutellaria baicalensis Georgi (Huang-qin) germplasm collection that was clonally maintained in in vitro for a period of over 6 years. Based on the FCM analysis of nuclei samples from(More)
Datura metel is a plant that contains several different neurologically active phytochemicals which affect human health. On-going research has examined the potential role of the human neuroindoles, melatonin and serotonin, in medicinal plants with neurological efficacy. In this report, we describe the quantification of melatonin and serotonin in flowers and(More)
MSI-99 is a synthetic analog of magainin II (MII), a small cationic peptide highly inhibitory to a wide spectrum of microbial organisms. Tomato plants were transformed to express a gene encoding the MSI-99 peptide and tested for possible enhancement of resistance to important pathogens of this crop. Thirty-six tomato transformants carrying an MSI-99(More)
In vitro and leaf disk assays of bacterial and fungal plant pathogens were conducted using three cationic lytic peptides, MSI-99, magainin II (MII), and cecropin B (CB). Growth of bacterial organisms was retarded or completely inhibited by low concentrations of these lytic peptides. The peptides also significantly reduced germination of fungal spores and(More)
Breadfruit (Artocarpus altilis, Moraceae) is a traditionally cultivated, high-energy, high-yield crop, but widespread use of the plant for food is limited by poor quality and poor storage properties of the fruit. A unique field genebank of breadfruit species and cultivars exists at the National Tropical Botanical Garden in the Hawaiian Islands and is an(More)
The genus Scutellaria in the family Lamiaceae has over 350 species, many of which are medicinally active. One species, Scutellaria baicalensis, is one of the most widely prescribed plants in Traditional Chinese Medicine, used for neurological disorders, cancer and inflammatory diseases and has been the subject of detailed scientific study but little is(More)
A detailed study was conducted to assess the effects of 12 different induction media on the gynogenesis response of four open-pollinated (OP) leek (Allium ampeloprasum L.) genotypes. Gynogenic plant production was induced in 11 of 12 induction media. However, leek genotypes showed substantial differences in their responses to the induction media. Two MS-,(More)
Hypericum perforatum L. (St. John’s wort) is an important medicinal herb and a subject of intensive research for its complex and diverse bioactive chemicals. An in vitro-grown germplasm collection of elite H. perforatum lines, established to provide easy access to physiologically uniform plants, was used for ploidy assessment studies. Germplasm lines were(More)
