“…Based on their geographical distributions, Sakamoto (1973Sakamoto ( , 1991 classified the Triticeae genera into two major groups: arctic-temperate group and east Mediterranean-central Asiatic group (Table 2.3), a classification that was supported by the studies of Hsiao et al (1995a) and Fan et al (2013). Most of the genera that developed in the east Mediterranean and central Asia regions belong to the subtribe Triticineae.…”

“…tauschii, whereas Crithopsis, Taeniatherum, Eremopyrum, and Henrardia, were close to Secale. Based on this finding, Hsiao et al (1995a) supported Sakamoto (1973), who suggested that the Triticeae should be classified as two major groups, a Mediterranean group and an Arctic-temperate group, where the Mediterranean lineage evolved from the Arctic-temperate species (Runemark and Heneen 1968;Sakamoto 1973). The inclusion of Crithopsis and Taeniatherum in the Mediterranean-Central Asiatic group is not merely due to their geographical distribution, but also to close phylogenetic relationships between the two genera, Crithopsis and Taeniatherum, and other Triticineae species.…”

“…Escobar et al (2011) reported that the clade containing Taeniatherum and Triticum-Aegilops is also seen on the 5S short-spacer data tree, but only if Elymus farctus and E. elongatus are included in the clade. Sakamoto (1973Sakamoto ( , 1991 classified the Triticeae into two groups based on their geographical distribution: the Arctic-Temperate group and the Mediterranean-Central Asiatic group (Table 2.3). Hsiao et al (1995a), analyzing ITSs of nuclear rDNA and sequences of tRNA in 30 diploid Triticeae species representing 19 genomes, found that most of the annuals of Mediterranean origin, i.e., species of Triticum, Aegilops, Crithopsis, Taeniatherum, Eremopyrum, Henrardia, Secale, and two perennials, Elymus farctus and Elymus elongatus, comprise a monophyletic group.…”

“…The very wide variation in the inflorescence traits and in the seed dispersal techniques among the genera and species of the Triticineae subtribe reflects rapid adaptation to the broad radiation that occurred in the habitats of the East Mediterranean and Central Asia regions (Sakamoto 1973). In accord with the above, several molecular studies proposed that a major radiation of the Triticineae occurred during a relatively narrow period of time in the late Miocene and early Pliocene (5.3 MYA).…”

Characterization of two novel γ-gliadin genes encoded by K genome of Crithopsis delileana and evolution analysis with those from Triticeae

et al. 2010

By acid polyacrylamide gel electrophoresis (A-PAGE) analysis, it was indicated that the electrophoresis mobility of gliadins from Crithopsis delileana (Schult) Roshev (2n=2x=14, KK) had obvious difference with those from common wheat in α, γ and ω region. Using homologous primers, two γ-gliadin genes (gli-Kr1 and gli-Kr2) were isolated from C. delileana, which had been deposited in the GenBank under accession numbers EU283818 and EU283821, respectively. Two γ -gliadin genes of C. delileana had the similar primary structures to the corresponding gene sequences from other wheat related species. The differences were mainly resulted from substitutions, insertions and deletions involving single amino acid residues or motifs of γ-gliadins. The repetitive domains of gli-Kr1 and gli-Kr2 from C. delileana are shorter than most of other sequences. By the alignment of γ-gliadin genes from A, B, D, A m , A u , S, S l , S sh , S s and S b genomes of Triticum and Aegilops, R genome of Secale (γ-secalin), Ee genome of Lophopyrum and K genome of Crithopsis in Triticeae, phylogenetic analysis indicated that two γ-gliadin genes of C. delileana could be clustered together with a γ-gliadin genefrom S sh genome of Aegilops by an interior paralleled branch. It was the first time that the γ-gliadin genes encoded by K genome of C. delileana were characterized. These could offer precious information for better understanding the qualities associated with gliadins, the response in coeliac disease and studying the evolutionary relationship of gliadins in Triticeae.
