Positive selection of Kranz and non-Kranz C4 phosphoenolpyruvate carboxylase amino acids in Suaedoideae (Chenopodiaceae)

In subfamily Suaedoideae, four independent gains of C4 photosynthesis are proposed, which includes two parallel origins of Kranz anatomy (sections Salsina and Schoberia) and two independent origins of single-cell C4 anatomy (Bienertia and Suaeda aralocaspica). Additional phylogenetic support for this hypothesis was generated from sequence data of the C-terminal portion of the phosphoenolpyruvat...

From proto-Kranz to C4 Kranz: building the bridge to C4 photosynthesis.

In this review, we examine how the specialized "Kranz" anatomy of C4 photosynthesis evolved from C3 ancestors. Kranz anatomy refers to the wreath-like structural traits that compartmentalize the biochemistry of C4 photosynthesis and enables the concentration of CO2 around Rubisco. A simplified version of Kranz anatomy is also present in the species that utilize C2 photosynthesis, where a photor...

Workflow Management in CLARIN-DK

Clarin.dk, the infrastructure maintained by the CLARIN-DK project, is not only a repository of resources, but also a place where users can analyse, annotate, reformat and potentially even translate resources, using tools that are integrated in the infrastructure as web services. In many cases a single tool does not produce the desired output, given the input resource at hand. Still, in such cas...

Smell: the Unappreciated Human Sense Adres Autorki

Molekularny mechanizm, poprzez który bodźce zapachowe są rozpoznawane, przekazywane i zamieniane w elektryczne impulsy nie był znany. Ludzie i zwierzęta mogą rozpoznawać w otaczającym środowisku około 1000 różnych lotnych chemicznych związków jako odrębne zapachy. Lecz jak organ węchowy rozpoznaje strukturalnie różnorodne chemiczne związki zapachowe i jak system nerwowy przekłada chemiczną stru...
