Diversification of inflorescence development in the PCK clade (Poaceae: Panicoideae: Paniceae)

American Journal of Botany, 2009
In grasses, inflorescence diversification and its correlation with species evolution are intriguing and not well understood. Part of this problem lies in our lack of comprehension about the inflorescence morphological complexity of grasses. We focused our study on the PCK clade (named for phosphoenol pyruvate carboxykinase), a well‐supported ...

Origin of a polyploid accession of Brachiaria humidicola (Poaceae: Panicoideae: Paniceae)

Genetics and Molecular Research, 2009
Brachiaria humidicola, a species adapted to poorly drained and infertile acid soils, is widely used throughout the tropics. Cytological characterization of 54 accessions of B. humidicola for breeding purposes revealed 2n = 36, 42, and 54 chromosomes. One accession (H030), with 2n = 42 chromosomes, showed a different meiotic behavior. In most accessions

Phylogenomics of Andropogoneae (Panicoideae: Poaceae) of Mainland Southeast Asia [PDF]

Systematic Botany, 2017
The grass tribe Andropogoneae is distributed in warm regions around the globe but has been poorly studied in mainland Southeast Asia. This is particularly true for the cosmopolitan genera Andropogon and Schizachyrium, with several species that appear to be narrowly distributed in this region. Additionally, lesser-known species in the genera Hemisorghum,
