Background and aims – New Caledonia is a hotspot of biodiversity in the world. Among most diverse Caledonian plant families Rubiaceae, which consist 30 genera containing 220 species, with level endemism 93%. The tribe Gardenieae represented by four genera, Gardenia (8 species), Aidia (2 Randia (7 Atractocarpus (10 species). As has now been restricted to Neotropics, species remain unplaced withi...

UNLABELLED • PREMISE OF THE STUDY The species-rich Neotropical genera Centropogon, Burmeistera, and Siphocampylus represent more than half of the ∼1200 species in the subfamily Lobelioideae (Campanulaceae). They exhibit remarkable morphological variation in floral morphology and habit. Limited taxon sampling and phylogenetic resolution, however, obscures our understanding of relationships bet...

Polyploidy plays a major role in the evolution of angiosperms with multiple paleopolyploid events having been suggested making it plausible that all angiosperms have a polyploid event in their history. Polyploidy can arise by genome duplication within a species (i.e., autopolyploidy), or whole genome duplication coupled with hybridization (i.e., allopolyploidy). Penstemon subsection Saccanthera...

We analysed transcription of the gene for the ribosomal protein (rp) L32 of the mouse, which is transcribed in mouse L1210 nuclear extracts in vitro. The rpL32 gene lacks a canonical TATA box. Hence it has been suggested that this gene has an alternative transcription pathway not requiring transcription factor IID (TFIID). Selective inactivation of TFIID in nuclear extract completely abolished ...

Linnaeoideae is a small subfamily of erect or creeping shrubs to small trees in Caprifoliaceae that exhibits a wide disjunct distribution in Eurasia, North America and Mexico. Most taxa of the subfamily occur in eastern Asia and Mexico but the monospecific genus Linnaea has a circumboreal to north temperate distribution. In this study, we conducted phylogenetic and biogeographic analyses for Li...

Solidago × niederederi (Asteraceae) is a natural hybrid of the native S. virgaurea and alien invasive canadensis, originated in Europe. Its naturalisation potential still questionable. One largest (more than 20 ramet clusters, treated as individuals) known population this nothospecies, located «Aleksin Bor» Natural Monument (Aleksin town, Tula Region, Russia) floodplain River Oka. We studied it...
