Distinct C4 sub‐types and C3 bundle sheath isolation in the Paniceae grasses [PDF]
In C4 plants, the enzymatic machinery underpinning photosynthesis can vary, with, for example, three distinct C4 acid decarboxylases being used to release CO2 in the vicinity of RuBisCO.

Macro-Climatic Distribution Limits Show Both Niche Expansion and Niche Specialization among C4 Panicoids. [PDF]
Grasses are ancestrally tropical understory species whose current dominance in warm open habitats is linked to the evolution of C4 photosynthesis. C4 grasses maintain high rates of photosynthesis in warm and water stressed environments, and the syndrome ...

Phylogenetics of Paniceae (Poaceae) [PDF]
Paniceae demonstrate unique variability of photosynthetic physiology and anatomy, including both non‐Kranz and Kranz species and all subtypes of the latter. This variability suggests hypotheses of independent origin or reversals (e.g., from C4 to C3). These hypotheses can be tested by phylogenetic analysis of independent molecular characters.

Phylogeny and photosynthesis of the grass tribe Paniceae [PDF]
PREMISE OF THE STUDY:The grass tribe Paniceae includes important food, forage, and bioenergy crops such as switchgrass, napiergrass, various millet species, and economically important weeds. Paniceae are also valuable for answering scientific and evolutionary questions about C4 photosynthetic evolution, drought tolerance, and spikelet variation ...

NOMENCLATURAL AND CRITICAL NOTES ON SOME BRAZILIAN SPECIES OF Paspalum (POACEAE: PANICEAE) [PDF]
A critical analysis of the type collections of 39 species names of Paspalum L. (Poaceae: Paniceae) from Brazil described by Swallen is presented along with comments based on more recent gatherings of the species. Eighteen new synonyms are proposed.

Novedades nomenclaturales en Cenchrus s.l. (Poaceae: Panicoideae: Paniceae)
Recientes estudios filogenéticos con datos morfológicos y moleculares aportaron evidencia sobre la monofilia de los géneros Cenchrus, Pennisetum y Odontelytrum y, por ello, se propuso su unificación y transferencia a Cenchrus, el cual tiene prioridad ...
