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...
متن کاملOn the identity and typification of Solanum brasilianum Dunal (Solanaceae)
Solanum brasilianum Dunal was described by Dunal in 1813 with reference only to an illustration in an 18th century work by Leonard Plukenet. Th e plate is diffi cult to interpret and no explicitly related specimens were available so the name S. brasilianum has long been regarded as “unresolved” and has never been used. Material matching the Plukenet plate was discovered in the herbarium of the ...
متن کاملSingle-Cell C4 Photosynthesis in Chenopodiaceae Species
Accurate three-dimensional imaging of plant structures and gene activity will facilitate a deeper understanding of the mechanisms that underlie plant growth and development. Lee et al. (pages 2145–2156) used optical projection tomography (OPT) to capture three-dimensional data from plant specimens. OPT has the advantages of other optical methods but with greater penetration and the ability to g...

Recently discovered regulators of asymmetric cell division highlight differences in the mechanisms responsible for cell fate segregation in plants and animals.
متن کاملKranz and single-cell forms of C4 plants in the subfamily Suaedoideae show kinetic C4 convergence for PEPC and Rubisco with divergent amino acid substitutions
The two carboxylation reactions performed by phosphoenolpyruvate carboxylase (PEPC) and ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) are vital in the fixation of inorganic carbon for C4 plants. The abundance of PEPC is substantially elevated in C4 leaves, while the location of Rubisco is restricted to one of two chloroplast types. These differences compared with C3 leaves have been...
