Phylogeny of the <I>Bouteloua curtipendula</I> Complex (Poaceae: Chloridoideae) Based on Nuclear Ribosomal and Plastid DNA Sequences from Diploid Taxa

Phylogeny and subgeneric classification of Bouteloua with a new species, B. herrera‐arrietae (Poaceae: Chloridoideae: Cynodonteae: Boutelouinae)

“…S2), and there is only a single sample of B. reflexa in the plastid tree. Therefore, we come to the identical conclusion as Sequeiros- Delgado et al (2013), that only B. triaena in sect. Bouteloua is monophyletic.…”

“…Gould & Kapadia (1964) included 12 species in their morphologically variable, B. curtipendula complex (B. sect. Bouteloua), and it has been hypothesized that hybridization has played a major role in the evolution of this group (Gould, 1980;Siqueiros-Delgado, 2001, 2007Siqueiros-Delgado et al, 2013). We include for the first time, the Central and South American, B. swallenii in this complex.…”

“…The B. curtipendula complex can be distinguished by having 12-80 pendulant, deciduous branches per inflorescence, relatively few 1-9 (-16) spikelets per branch, and spikelets that fall intact with the branch axis (Siqueiros-Delgado et al, 2013). Anatomically, is has round and peripheral chloroplasts within the Kranz cells in leaves and culms, except for B. juncea (Columbus, 1996;Siqueiros-Delgado, 2007), and by displaying an anatomically and biochemically intermediate NAD-ME/PCK C 4 pathway (Hattersley & Browning, 1981;Prendergast et al, 1987).…”

Since all morphological features used to circumscribe the species in this complex were found to be homoplasious (Siqueiros-Delgado et al, 2013) we will not discuss morphological features differentiating among species. In our overall combined tree (Fig.…”

The chloroplast genome of the hexaploid Spartina maritima (Poaceae, Chloridoideae): Comparative analyses and molecular dating

“…the cssA, matK, ndhF and rps3 genes (Hilu and Alice 2001;Peterson et al, 2010aPeterson et al, , 2010bPeterson et al, 2012); the ndhA, rps16 and trnL introns (Peterson et al 2014b); and the rpl32-trnL, trnK-rps16 and trnT-trnL intergenic spacers (Baumel et al, 2002;Columbus et al, 2007;Peterson et al, 2012Peterson et al, , 2014bSiqueiros-Delgado et al, 2013). Here, we provide an additional set of variable genic (ndhA,ndhH,ndhI,petA,petB),intronic (atpF,petB,rpl16,trnK_UUU,petB and ycf3) and intergenic (ndhC-trnV, petN-trnC, ndhF-rpl32, atpI-atpH, trnF-ndhJ, trnG-trnT, petA-psbJ, ycf3-trnS, trnD-psbM, rps16-trnQ, trnT-trnE, trnP-psaJ) markers that will facilitate tracking the evolutionary history of Chloridoideae.…”
