Tribe Triticeae

Secale is a small but very diverse genus from the tribe Triticeae (family Poaceae), which includes annual, perennial, self-pollinating and open-pollinating, cultivated, weedy and wild species of various phenotypes. Despite its high economic importance, classification of this genus, comprising 3–8 species, is inconsistent. This has resulted in significantly reduced progress in the breeding of rye which could be enriched with functional traits derived from wild rye species. Our previous research has suggested the utility of non-coding sequences of chloroplast and mitochondrial DNA in studies on closely related species of the genus Secale. Here we applied the SPInDel (Species Identification by Insertions/Deletions) approach, which targets hypervariable genomic regions containing multiple insertions/deletions (indels) and exhibiting extensive length variability. We analysed a total of 140 and 210 non-coding sequences from cpDNA and mtDNA, respectively. The resulting data highlight regions which may represent useful molecular markers with respect to closely related species of the genus Secale, however, we found the chloroplast genome to be more informative. These molecular markers include non-coding regions of chloroplast DNA: atpB-rbcL and trnT-trnL and non-coding regions of mitochondrial DNA: nad1B-nad1C and rrn5/rrn18. Our results demonstrate the utility of the SPInDel concept for the characterisation of Secale species.

Tandem repetitive Afa-family sequences of 340 bp are known to occur in wheat and related species of tribe Triticeae. We isolated six and three Afa-family sequences from Leymus racemosus and Psathyrostachys juncea, respectively, both of which are perennial species. The sequences account for 0.5% and 0.2% of L. racemosus and P. juncea genomes, respectively, and using in situ hybridization were located in subtelomeric and interstitial regions of L. racemosus chromosomes. These sequences are clustered with those of Elymus trachycaulus in the phylogenetic tree. Our findings indicate that the Afa-family sequences have been amplified at least twice in the lineage of L. racemosus, P. juncea, and E. trachycaulus.Key words: Triticeae, Leymus, Psathyrostachys, tandem repeat, Afa-family sequences.
