The phylogenetic position of 40 species in 21 genera is presented in this study for the first time, elucidating their position in Abildgaardieae (Trachystylis), CryptangIEae (Didymiandrum, Exochogyne), Cypereae (Androtrichum, Volkiella), Eleocharideae (Chillania), and Schoeneae (Calyptrocarya, Morelotia).
What is a Genus in Cypereae: Phylogeny, Character Homology Assessment and Generic Circumscription in Cypereae

- BiologyThe Botanical review
- 1 February 2009
Using a DNA-based tree as the framework, the homology of key taxonomic characters in tribe Cypereae is assessed and the question of generic circumscription is revisited, to include all taxa with a Cyperus-type embryo and perianth segments.
An assessment of suprageneric phylogeny inCyperaceae usingrbcL DNA sequences

- BiologyPlant Systematics and Evolution
- 1 September 1998
The phylogeny of suprageneric groups inCyperaceae has been examined by cladistic analysis ofrbcL sequence data of 80 species in 40 genera. The results support the family as monophyletic and derived…
Phylogeny of Cyperaceae based on DNA sequence data - a new rbcL analysis
- D. Simpson, A. M. Muasya, Xiufu Zhang
- Biology
- 2007
A parsimony analysis was carried out using all rbcL sequences currently available for Cyperaceae, including data for two new genera, with one outcome may be that only two subfamilies, Mapanioideae and Cyperoideae, are recognized.

Engineering natural human vaginal isolates of Lactobacillus jensenii to secrete two-domain CD4 (2D CD4) proteins represents an important first step toward the development of engineered commensal bacteria within the vaginal microflora to inhibit heterosexual transmission of HIV.

Cultivation experiments suggested that stem elongation and axillary stem production was significantly (P<O·OOl) greater in E. nuttallii under nutrient-poor and -rich conditions and a range of light intensities.

A novel, live microbicide that employs a natural vaginal strain of Lactobacillus jensenii engineered to deliver the potent HIV inhibitor cyanovirin-N (CV-N), capable of inhibiting CCR5-tropic HIVBaL infectivity in vitro and in vivo.
Phylogenetic relationships in Cyperaceae subfamily Mapanioideae inferred from pollen and plastid DNA sequence data.

- 1 July 2003
New groupings within the subfamily Mapanioideae have been discovered based on the specialization of some taxa in terms of their pollination biology, including one that includes two taxa from Hypolytreae, Capitularina and Exocarya.
