Anatomical enablers and the evolution of C4 photosynthesis in grasses
- P. Christin, C. Osborne, +6 authors E. Edwards
- Biology, Medicine
- Proceedings of the National Academy of Sciences
- 24 December 2012
C4 photosynthesis is a series of anatomical and biochemical modifications to the typical C3 pathway that increases the productivity of plants in warm, sunny, and dry conditions. Despite its… Expand
PHYLOGENETICS OF ANDROPOGONEAE (POACEAE: PANICOIDEAE) BASED ON NUCLEAR RIBOSOMAL INTERNAL TRANSCRIBED SPACER AND CHLOROPLAST trnL-F SEQUENCES
- Elizabeth M. Skendzic, J. Columbus, R. Cerros-Tlatilpa
- Biology
- 2007
Phylogenetic relationships among 85 species representing 35 genera in the grass tribe Andropogoneae were estimated from maximum parsimony and Bayesian analyses of nuclear ITS and chloroplast trnL-F… Expand
Phylogenetics of Chloridoideae (Gramineae): a Preliminary Study Based on Nuclear Ribosomal Internal Transcribed Spacer and Chloroplast trnL–F Sequences
- J. Columbus, R. Cerros-Tlatilpa, +4 authors Nancy F. Refulio-Rodriguez
- Biology
