Transferability of barley and wheat EST-microsatellite markers in some Poaceae members
Öz
The cross species transferability of barley and wheat microsatellite markers developed from expressed sequence tag (EST) libraries constructed under Fusarium infection conditions were detected among 17 species including 8 from Aegilops, 6 from Triticum, Zea mays, Avena sativa, Oryza sativa.
Transferability rates of barley microsatellite primer pairs ranged from 29% to 100%. A maximum of 100% cross-genera transferability noticed with Avena followed by Zea (92%), Triticum (83%), Aegilops (68%), and Oryza (8%). Primer pairs were highly transferable within species of Triticum (100% in T. turgidum durum durum, 92% in T. turgidum durum dicoccon and T. monococcum aegilopoides, 83% in T.timopheevii timopheevii and T. turgidum dicoccoides, 67% in T. timopheevii armeniacum). Only one primer pairs (contig624) showed 100 % cross-species/genera amplification in all materials studied.
Considering wheat microsatellites, the microsatellite primer pairs were highly transferable within species of Triticum (ranged from %100 to %70) and but low transferable in the allied cereals (15% in Avena, 50% in Oryza, 45% in Zea, 60% in Hordeum). Two primer pairs have shown transferability only in some Triticum species, while two others showed amplication only in species of Aegilops and Triticum. Only one primer pairs showed 100 % cross-species/genera amplification in all materials studied.
This higher cross-species transferability of EST microsatellite markers indicated a high level of conservation of DNA sequences belonging to the transcribed region of the genome and its suitability in comparative genome mapping, genetic diversity and phylogenetics analysis.
