“…Bisht and Mukai (2002) also found a similar genome composition based on chromosome banding pattern. Artificial hybrids between these 2 species had intermediate morphologies (Mehra, 1962), and a close relationship between these 2 species was confirmed by previous molecular data (Hilu and De Wet, 1976;Neves et al, 2005;Liu et al, 2011). However, the B homoeologues in clade W-B1 do not have any diploid taxa (possible paternal parents), as confirmed by ITS, Pepc4, and EF-1α phylogenies (Neves et al, 2005;.…”

“…Regarding the close phylogenetic relationships of diploids E. indica (also known to have tetraploid individuals) and E. tristachya with E. africana, E. coracana, and E. kigeziensis in both cpDNA (Neves et al, 2005) and nrDNA Pepc4 and waxy (Figure 1) phylogenies, we propose that diploids E. indica and E. tristachya might be the A-genome parents of the E. africana-E. coracana subclade. This conclusion is substantiated by 2 previously reported results.…”

“…However, the putative A-genome parents involved in the evolution of finger millet remain controversial (Bisht and Mukai, 2001;Neves et al, 2005;Liu et al, 2011). An ITS phylogenetic tree suggested E. indica as the A-genome (maternal) parent of E. coracana (Neves et al, 2005). This was also supported by single-probe genomic in situ hybridization (GISH), cpDNA restriction sites, and isozyme analyses (Hilu, 1988;Werth et al, 1994;Mukai, 2001, 2002).…”

Eleusine coracana (L.) Gaertn. (finger millet) is the third most important cereal crop in semiarid regions of the world, but the degree of relatedness of finger millet with other species in the genus is unverified. The study of morphological character evolution in Eleusine Gaertn. has lagged behind due to lack of relevant research. Polyploidy history of finger millet was analyzed using waxy sequences together with multicolor genomic in situ hybridization (McGISH). In the waxy phylogenetic tree, sequences of 2 homoeologous loci were isolated from 3 tetraploids: Eleusine coracana, E. africana Kenn.-O'Byrne, and E. kigeziensis S.M.Phillips. The 3 species grouped with E. indica (L.) Gaertn. and E. tristachya (Lam.) Lam. in the W-A1 clade (A-type sequences). The W-B1 and W-B2 clades (B-type sequences) were composed of the E. africana-E. coracana and the E. jaegeri Pilg.-E. kigeziensis subclades, respectively. Eleusine indica probes produced stronger signals of relative intensities across A-genome chromosomes of finger millet than did the E. tristachya probes. The waxy phylogenetic tree and McGISH evidence support E. indica and E. tristachya (or its extinct sister or ancestor) as the primary and secondary A-genome parents for finger millet, respectively. The most likely scenario is that the B-genome donor is extinct. Five morphological characters were found to be homoplasious by optimization on waxy gene tree.

“…In order to gain more information for phylogenetic reconstruction many chloroplast regions have been analyzed, including genes and intergenic spacers. Because of the low frequency of structural changes in the chloroplast DNA molecule (cpDNA) together with a low rate of sequence evolution, the plastome (plastid genome) is considered a useful tool for plant phylogenetic studies, especially above the species level (Chiang and Schaal 2000, Ingvarsson et al 2003, Kelchner 2000, Neves et al 2005, Odintsova and Yurina 2003. The sequences of the chloroplast rbcL gene (coding the large subunit of Rubisco) as well as a few other genes (i.e.…”

“…matK, ndhF, psaB and trnL-trnF) have been widely used for inferring phylogeny in plants (Chiang and Schaal 2000, Oxelman et al 1999, Soltis et al 2000, Miz et al 2008). Supposed to evolve more rapidly than coding regions, chloroplast non-coding DM Melotto-Passarin et al sequences such as the intergenic spacer between the trnL (UUA) 3´ exon and the trnF (GAA) gene (Neves et al 2005, Miz et al 2008, the atpB-rbcL spacer (Chiang andSchaal 2000, Soltis et al 2000) and trnC-trnD spacer (Lee and Wen 2004) have been used to address questions concerning relationships among related species or also related genera. Clarkson et al (2004) studied the phylogenetic relationships in Nicotiana (Solanaceae) inferred from the plastid DNA regions trnL intron, trnL-F spacer, trnS-G spacer and two genes, ndhF and matK.…”

The non-coding trnE-trnT intergenic spacer of cpDNA was analyzed to assess the nucleotide sequence polymorphism of 16 Solanaceae species and to estimate its ability to contribute to the resolution of phylogenetic studies of this group. Multiple alignments of DNA sequences of trnE-trnT intergenic spacer made the identification of nucleotide variability in this region possible and the phylogeny was estimated by maximum parsimony and rooted with Convolvulaceae Ipomoea batatas, the most closely related family. Besides, this intergenic spacer was tested for the phylogenetic ability to differentiate taxonomic levels. For this purpose, species from four other families were analyzed and compared with Solanaceae species. Results confirmed polymorphism in the trnE-trnT region at different taxonomic levels.
