“…However, some rare species showed their phylogenetic relationship with more than one taxon as shown in Figures 3, 4 and 5. Thus, nrDNA-ITS, is a potential marker for the phylogenetic study as it has been used in many taxa such as Silene section Melandrium (Rautenberg et al, 2010), Crocus (Harpke et al, 2012), Ficus (Kusumi et al, 2012), etc. The cladding of these taxa depended on the sequence similarity to those sequences retrieved from the GenBank database.…”

ABSTRACT.The rare and endangered plants of any country are important genetic resources that often require urgent conservation measures. Assessment of phylogenetic relationships and evaluation of genetic diversity is very important prior to implementation of conservation strategies for saving rare and endangered plant species. We used internal transcribed spacer sequences of nuclear ribosomal DNA for the evaluation of sequence identity from the available taxa in the GenBank database by using the Basic Local Alignment Search Tool (BLAST). Two rare plant species viz, Heliotropium strigosum claded with H. pilosum (98% branch support) and Pancratium tortuosum claded with P. tenuifolium (61% branch support) clearly. However, some species, viz Scadoxus multiflorus, Commiphora myrrha and Senecio hadiensis showed close relationships with more than one species. We conclude that nuclear ribosomal internal transcribed spacer sequences are useful markers for phylogenetic study of these rare plant species in Saudi Arabia.

“…PCR primers for the other 2 regions (rps16-trnQ and matK-trnK) were newly designed for this study. Harpke et al (2013) analyzed diverse morphological characters traditionally used in Crocus taxonomy regarding their potential to discern monophyletic groups within the genus. They concluded that none of the morphological characters were unequivocally able to discern sections or series within the genus.…”

occurring from western Europe and northwestern Africa to western China, with the center of species diversity on the Balkan Peninsula and in Turkey. Many crocuses are known as popular ornamentals, and saffron, the dried styles of C. sativus L., is one of the world's most expensive spices. Molecular systematic studies (Petersen et al., 2008;Seberg and Petersen, 2009;Harpke et al., 2013) recently showed that several of the infrageneric taxonomic units of Mathew's (1982) revision of the genus are not monophyletic. Among them is series Reticulati B.Mathew of section Nudiscapus B.Mathew, with species occurring in the phylogenetic trees in clades intermingled with taxa of series Biflori B.Mathew and series Speciosi B.Mathew. Traditionally, within C. reticulatus, a species described from the Caucasus (Weber and Mohr, 1805), 2 subspecies are recognized on morphological grounds: subsp. reticulatus and subsp. hittiticus (T.Baytop & B.Mathew) B.Mathew (Mathew, 1982), occurring from Italy to southwestern Russia and Turkey. However, according to Mathew, subsp. reticulatus is highly heterogeneous, including 3 cytotypes with 2n = 10, 12, and 14 chromosomes. Under subsp. reticulatus Mathew (1982) subsumed as synonyms several taxa, such as, for instance, C. micranthus and C. variegatus. To arrive at a systematic treatment of Crocus that reflects natural relationships among taxa we are currently analyzing and circumscribing monophyletic units of the genus (Kerndorff et al., 2013;Harpke et al., 2014). Here we provide data for the C. reticulatus species group in its new definition based on 2 molecular data sets and morphological characters.Molecular markers are able to provide higher numbers of qualitative characters for closely related taxa
