TL;DR: In this paper, C4 graminoids were obtained from the Serengeti National Park of Tanzania to evaluate potential limiting interactions between energy and nutrient flows in grazing ecosystems, and plants were grown hydroponically at solution phosphorus concentrations of 10 and 100 μmol/L and were either unclipped or clipped weekly to a height of 3 cm for 5 weeks.
Abstract: Kyllinga nervosa (Cyperaceae) and Digitaria macroblephara (Poaceae), C4 graminoids, were obtained from the Serengeti National Park of Tanzania. Kyllinga is most abundant on high pH, high calcium, low phosphorous, carbonatitic ash—derived soils, and Digitaria is more abundant on neutral, lower calcium, higher P soils. Both species come from intensely grazed grasslands. Plant responses to different nutritional levels and defoliation were measured to evaluate potential limiting interactions between energy and nutrient flows in grazing ecosystems. Plants were grown hydroponically at solution phosphorus concentrations of 10 and 100 μmol/L and were either unclipped or clipped weekly to a height of 3 cm for 5 wk. At that time, the kinetics of P uptake were measured with 32P, plants were harvested, and dry masses and the tissue concentrations of P and N were determined. Clipping and P concentration of the growth medium both had major effects upon yields of all plant components. Total yield of Kyllinga was highest...

TL;DR: A phylogenetic framework for revising the classification and character evolution in Cyperus s.s.l. is established and despite the lack of resolution along the backbone of the C4 CyPerus clade and for some internal branches, several well-supported clades can be distinguished.

TL;DR: In genera from two dicotyledonous families, Amaranthaceae and Chenopodiaceae, the occurrence of the C 4 -dicarboxylic acid pathway of photosynthesis correlates with low ribulose diphosphate carboxylase activity, high activities of phosphopyruvate car boxylase and phosphate synthetase, a unique type of leaf anatomy, and high photosynthesis rates.

TL;DR: The phylogeny of Cyperus and allied genera has been reconstructed using cladistic analysis of plastid rbcL gene, rps16 intron, trnL introns, and trnF-F intergenic spacer sequence data in 40 species of tribe Cypereae.
