@ARTICLE{TreeBASE2Ref29588, author = {sajjad Asaf}, title = {First complete plastid genome sequence of Plantago ovata and its comparative analysis: Expanded inverted repeat (IR) region with large scale inversion}, year = {2019}, keywords = {Plastome genome, Plantago ovata, Comparative analysis, IR extension, inversion}, doi = {}, url = {http://}, pmid = {}, journal = {Scientific Reports}, volume = {}, number = {}, pages = {}, abstract = {Plantago ovata is an economically and medicinally important species of genus Plantago. Herein, we sequenced the complete plastome genome of P. ovata by using Illumina HiSeq-2000 platform and performed comparative analysis with previously published genome from family Plantaginaceae. The results revealed that P. ovata plastome is 162,116 bp with a typical quadripartite structure, containing a large single copy region of 82,084 bp and small single copy region of 5,272 bp. The genome contained markedly higher inverted repeats size up to 37.4 kb suggesting large scale inversion of 13.8 kb within the expanded inverted repeat regions. The plastome of P. ovata contain 149 different genes, including 43 tRNA, 8 rRNA and 98 proteins coding. The analysis revealed 139 microsatellites, where 71 were found in non-coding regions. Similarly, about 32 forward, 34 tandem and 17 palindromic repeats were also detected. The complete genome sequences, 72 shared genes, matK and rbcL genes from related species suggested that P. ovata formed single clade with P. maritima and P. media in phylogenetic analysis. The result concludes that P. ovata has significant variation in inverted repeat region, which suggest the stability of plastome genome of P. ovata as compared to other species of Plantaginaceae. } }
