Many studies have shown that clonal integration can promote the performance of clonal plants in heterogeneous habitats, but the roles of clonal integration in both heterogeneous and homogeneous habitats were rarely studied simultaneously. Ramet pairs of Alternanthera philoxeroides (Mart.) Griseb were placed in two habitats either heterogeneous or homogeneous in soil nutrient availability, with ...

BACKGROUND COUP transcription factors are required for the regulation of gene expression underlying development, differentiation, and homeostasis. They have an evolutionarily conserved function, being a known marker for neurogenesis from cnidarians to vertebrates. A homologue of this gene was shown previously to be a neuronal and nematocyte differentiation marker in Hydra. However, COUP-TFs had...

Polypyrimidine tract-binding (PTB) proteins are a family of RNA-binding proteins that function in a wide range of RNA metabolic processes by binding to motifs rich in uracils and cytosines. A PTB protein of pumpkin was identified as the core protein of an RNA-protein complex that trafficks RNA. The biological function of the PTB-RNA complex, however, has not been demonstrated. In potato, six PT...

The BEL1-like family of transcription factors is ubiquitous in plants and plays important roles in regulating development. They function in tandem with KNOTTED1 types to bind to a double TTGAC motif in the upstream sequence of target genes. StBEL5 of potato (Solanum tuberosum) functions as a mobile RNA signal that is transcribed in leaves, moves down into stolons in response to short days, and ...
