The successful application of DNA barcoding as a tool for species discrimination and identification depends on the adequacy of barcode reference libraries of well identified species. Next generation sequencing (NGS) methods have proven to be more promising especially for herbarium specimen containing degraded DNA than conventional barcoding. To make a...
A method of ND FISH was employed to identify structural variation in Beta vulgaris subsp. maritima and to evaluate the impact of this variation on meiotic behaviours, specifically synapsis and segregation of chromosomes. An intercalary region (pEV1) on the chromosome IV arm exhibited asymmetry in signals, allowing individual homologues to...
The Indonesian island of Sulawesi is comprised of a mosaic of soil types including the largest ultramafic outcrops in the tropics (ultramafic soils are macronutrient low and phytotoxic heavy metal rich). The island’s ontogeny is also distinctive, whereby it has formed only recently < 2 million years ago via agglomeration...
