Description
| - Pro klasifikaci skupin taxonů z rodu Poa s různými typy plastidových genomů byly použity indely (inzerce/delece) z trnL intronu a trnL-trnF mezigenového spaceru (IGS). V rámci 11 z 13 sekcí rodu Poa prezentovaných ve díle Flora Europaea bylo nově sekvencováno celkem 23 taxonů (P. alpina, P. badensis, P. bulbosa, P. crassipes, P. molinerii, P. annua, P. chaixii, P. granitica, P. pratensis, P. sibirica, P. remota, P. botryoides, P. cenisia, P. compressa, P. laxa, P. margilicola, P. media, P. nemoralis, P. palustris, P. pannonica, P. pirinica, P. riphaea, and P. sejuncta) a dále 18 sekvencí, dostupných z databáze NCBI. Vzorky pocházely převážně ze střední Evropy. Sekvenční paterny indelů, zahrnující méně než 0.7 % plastidového genomu, potvrdily čtyři skupiny taxonů, již dříve vymezené na základě restrikční analýzy celé plastidové DNA. Zjištěné indely byly téměř vždy unikátní pro danou skupinu a nebylo je proto možné využít k posouzení vzájemné příbuznosti skupin. Byly však užitečné pro infragenerickou kl (cs)
- The use of insertion/deletion (indel) patterns from sequences of the trnL intron and trnL-F intergenic spacer (IGS) in finding plastid genome types of the genus Poa L. was studied. New sequences for 23 taxa (P. alpina, P. badensis, P. bulbosa, P. crassipes, P. molinerii, P. annua, P. chaixii, P. granitica, P. pratensis, P. sibirica, P. remota, P. botryoides, P. cenisia, P. compressa, P. laxa, P. margilicola, P. media, P. nemoralis, P. palustris, P. pannonica, P. pirinica, P. riphaea, and P. sejuncta) and 18 previously published sequences, which represent 11 of the 13 sections listed for Poa in Flora Europaea, were investigated. Collections were made primarily in central Europe. Indel patterns, despite sampling less than 0.7 % of the plastid genome, produced four taxa groupings that were congruent with the major divisions obtained in intensive, previously published restriction site studies. Insertion/deletion events in the trnL intron and trnL-trnF IGS were in nearly all cases unique to a single patter
