“…Morphologically, the seed husk of P. ovata is enclosed by a thin white membrane, usually known as Blonde Psyllium in English. The genetic diversity of Plantago species is important for breeding various cultivars, which are valuable additions that are resistant to different diseases 19 . The meiotic system and chromosomal structure of P. ovata have various features which account for its narrow genetic base such as a small 621-Mb genome size with 4 (2n = 2x = 8) chromosomes 20 .…”

“…The ITS and 5S rRNA regions depicted on the sequence data showed that P. ovata is closely related to P. arenaria 23 . In recent time with the advancement in molecular techniques, different molecular markers were used to access the intra and interspecific relationship among Plantago species 19,24 . However, such studies investigated smaller intraspecific diversity than the interspecific diversity.…”

Plantago ovata (plantaginaceae) is an economically and medicinally important species, however, least is known about its genomics and evolution. Here, we report the first complete plastome genome of P. ovata and comparison with previously published genomes of related species from plantaginaceae. the results revealed that P. ovata plastome size was 162,116 bp and that it had typical quadripartite structure containing a large single copy region of 82,084 bp and small single copy region of 5,272 bp. The genome has a markedly higher inverted repeat (IR) size of 37.4 kb, suggesting large-scale inversion of 13.8 kb within the expanded IR regions. In addition, the P. ovata plastome contains 149 different genes, including 43 tRNA, 8 rRNA, and 98 protein-coding genes. The analysis revealed 139 microsatellites, of which 71 were in the non-coding regions. Approximately 32 forward, 34 tandem, and 17 palindromic repeats were detected. The complete genome sequences, 72 shared genes, matK gene, and rbcL gene from related species generated the same phylogenetic signals, and phylogenetic analysis revealed that P. ovata formed a single clade with P. maritima and P. media. the divergence time estimation as employed in BeASt revealed that P. ovata diverged from P. maritima and P. media about 11.0 million years ago (Mya; 95% highest posterior density, 10.06-12.25 Mya). In conclusion, P. ovata had significant variation in the IR region, suggesting a more stable P. ovata plastome genome than that of other plantaginaceae species.

“…DNA ngerprinting of all the genetic stocks is imperative in order to preparing a powerful molecular database of medicinal plants (WJITKUS et al, 1994). The most important characteristics of molecular markers are neutrality, not in uenced by age, environment, economical bene ciary and more informative than morphological traits (SAMANTARAY et al, 2010;RAHIMI et al, 2018). Inter simple sequence repeat (ISSR) marker is preferred by many researchers due to many advantages such as simplicity, quickly, less costly and high reproducibility (PRADEEP REDDY et al, 2002;XU et al, 2018).…”

Cuminum cyminum (as an aromatic herb) is the sources of cumin, which has been commonly used in traditional medicine for the treatment of various diseases especially in tropical Asia. Thus, the current experiment was performed to accesses molecular genetic diversity among 22 collected accessions of cumin from different area of Iran, based on inter simple sequence repeat (ISSR) markers and start codon targeted (SCoT) markers. Analysis of molecular variance revealed that a significant genetic difference between the studied accessions reach to 43%. Mantel test between genetic diversity and geographical distance indicated that an increase in geographical distance of collected accessions did not influence on genetic differentiation. Results about all agro-morphological traits showed a significant difference between the ecotypes except the number of branches. Canonical correspondence analysis ballot of genetic features and environmental factors included 5 geographic and climatic factors for seed origin’s habitat, which have been show that the mentioned parameters had no strong effect on the plant genotypes. However, difference in elevation and latitude of accession origins had effect on genetic clustering in two major groups. The consensus tree of both molecular and morphological data relieved that the accessions Chah-Dashi, Damghan, Ferdows and Nehbandan formed discreet clusters based on genetic and agro-morphological features. In conclusion, the results confirmed that both ISSR and SCoT markers were reliable and useful tools for analyzing the genetic diversity of cumin in Iran.
