Calligonum is the only C4 genus within Polygonaceae. We applied DNA sequences from
the nuclear ribosomal internal transcribed spacer (nrITS) and five plastid genome regions …

This study represents phylogenetic analyses of two woody polygonaceous genera
CALLIGONUM and PTEROPYRUM using both chloroplast fragment (trnL-F) and the nuclear …

Quaternary climatic oscillations appear to have influenced the genetic diversity and
evolutionary history of arid-adapted plants. To understand the processes involved and …

Abstract Background Calligonum (Polygonaceae) is distributed from southern Europe
through northern Africa to central Asia, and is typically found in arid, desert regions. Previous …

Several lines of evidence including morphology, chromosome numbers, karyotypes, and
phenology were previously used to clarify the taxonomic relationship between Calligonum …

Few studies have addressed the evolutionary relationships within Polygonaceae from a
global perspective. The convoluted taxonomic history of Polygonaceae is a major barrier to …

Plantago sect. Coronopus contains our two focal species (P. coronopus L., P. crassifolia
Forssk.), both with an overall conspicuous bi‐hemispheric distribution range (Mediterranean …

The subfamily Polygonoideae has a world‐wide distribution and is an important component
of many countries' floras. In this study we present the most comprehensive sampling …

The phylogeny of Polygonum sect. Cephalophilon was analyzed using the chloroplast
genes trnL-F, rbcL and nuclear ribosomal ITS sequences. Individual and combined analyses …

Calligonum jeminaicum ZM Mao, a species regarded as endemic to China, was thought to
be nonexistent owing to a lack of scientific records. The similarity of C. jeminaicum to C …
