“…Despite the incomplete molecular knowledge of the Brassicaceae, a number of monophyletic clades or alliances have been identified based on Kropf (2002), Warwick et al (2002Warwick et al ( , 2004aWarwick et al ( , 2004bWarwick et al ( , 2005aWarwick et al ( , 2005b, , Warwick and Sauder (2005), and Beilstein et al (2006). Most of these major clades or alliances are recognized herein at the tribal level.…”

“…Although Hedinia also has the same leaf and trichome characters, he (1936) assigned it to the tribe Lepidieae because of having angustiseptate fruits. However, Warwick et al (2004b) demonstrated that there are no solid morphological grounds to maintain the smaller genera above as independent of Smelowskia.…”

“…The Sisymbrieae was recognized as a tribe of 70 genera and 400 species (Schulz 1936, Al-Shehbaz 1988c, but molecular data (see Warwick et al 2002Warwick et al , 2004aWarwick et al , 2004bWarwick et al , 2005Koch et al 2003a) supported the removal of many of its component genera to other tribes. The tribe is monophyletic and is sister to the Schizopetaleae (Beilstein et al 2006) or the Brassiceae (Warwick et al 2002.…”

Systematics and phylogeny of the Brassicaceae (Cruciferae): an overview

2006

Abstract. A critical review of characters used in the systematics of the Brassicaceae is given, and aspects of the origin, classification, and generic delimitation of the family discussed. Molecular phylogenetic studies of the family were reviewed, and major clades identified. Based on molecular studies, especially from the ndhF chloroplast gene, and careful evaluation of morphology and generic circumscriptions, a new tribal alignment of the Brassicaceae is proposed. In all, 25 tribes are recognized, of which seven (Aethionemeae, Boechereae, Descurainieae, Eutremeae, Halimolobeae, Noccaeeae, and Smelowskieae) are described as new. For each tribe, the center(s) of distribution, morphology, and number of taxa are given. Of the 338 genera currently recognized in the Brassicaceae, about 260 genera (or about 77%) were either assigned or tentatively assigned to the 25 tribes. Some problems relating to various genera and tribes are discussed, and future research developments are briefly covered.

“…These independent markers are widely applied in phylogenetic studies across the Brassicaceae and have helped in unraveling relationships within and among various taxa and major lineages (e.g., Franzke et al 1998Franzke et al , 2004Al-Shehbaz 2002, 2004;Mummenhoff et al 2004;Lihová et al 2004Lihová et al , 2006aWarwick et al 2004aWarwick et al , b, 2006bWarwick and Sauder 2005;Yue et al 2008;Carlsen et al 2009;Mummenhoff et al 2009;Jordon-Thaden et al 2010). …”

Molecular phylogeny and systematics of the tribe Chorisporeae (Brassicaceae)

et al. 2011

Sequence data from nuclear (ITS) and chloroplast (trnL-F) regions for 89 accessions representing 56 out of 64 species from all five genera of the tribe Chorisporeae (plus Dontostemon tibeticus) have been studied to test the monophyly of the tribe and its component genera, clarify its boundaries, and elucidate its phylogenetic position in the family. Both data sets showed strong support for the monophyly of the Chorisporeae as currently delimited, though the position of its tentative member D. tibeticus was not resolved by ITS. Parrya and Pseudoclausia are polyand paraphyletic with regard to each other, and Chorispora is either polyphyletic or at least paraphyletic (comprising Diptychocarpus) within a weakly supported monophyletic clade. The incongruence in branching pattern among the markers was most likely caused by hybridization and possibly influenced by incomplete lineage sorting. The present results suggest uniting Pseudoclausia, Clausia podlechii, and Achoriphragma with Parrya and transferring P. beketovii and P. saposhnikovii to Leiospora (Euclidieae). We also obtained support for splitting Chorispora into two geographically defined groups, one of which is closer to Diptychocarpus. Both data sets revealed a close relationship of the Chorisporeae to Dontostemoneae, while ITS also indicated affinity to Hesperideae. Therefore, the position of Chorisporeae needs further verification.

“…Many examples of hybrid detection involve investigation of the additivity of nucleotides at single positions (polymorphic sites) of rDNA ITS sequences (e.g., Gravendeel & al., 2004;Koontz & al., 2004;Peterson & al., 2004;Warwick & al., 2004). An example of intraspecific ITS additivity can be found in Clausia aprica (Brassicaceae) where accessions of an intermediate group showed additivity, possibly indicating hybridization .…”
