Subject:
DNA barcoding,   etc   ; macroalgae; taxonomy;     Show all 3 Subjects
Abstract:
... Although there are different naming systems for economic seaweeds, including local vernacular, legal, and institutional names, there is a general understanding that naming systems are underpinned by correct scientific taxonomy and nomenclature. The molecular revolution in taxonomy, causing huge changes in delimitation of taxa, together with a perceived inability of scientific taxonomy and nomencla ...

Abstract:
... The spatial distribution of molecules and cells is fundamental to understanding biological systems. Traditionally, microscopies based on electromagnetic waves such as visible light have been used to localize cellular components by direct visualization. However, these techniques suffer from limitations of transmissibility and throughput. Complementary to optical approaches, biochemical techniques s ...

Abstract:
... BACKGROUND: The angiosperm family Bromeliaceae comprises over 3.500 species characterized by exceptionally high morphological and ecological diversity, but a very low genetic variation. In many genera, plants are vegetatively very similar which makes determination of non flowering bromeliads difficult. This is particularly problematic with living collections where plants are often cultivated over ...

The main features to distinguish the seven native Utricularia species occurring in central Europe are found in flower shape, but being rarely flowering identification is often doubtful and uncertain. A recent morphometric work highlighted that there are no univocal reliable extra-floral morphological features allowing a safe identification at species level. Therefore, DNA barcoding approach is att ...
