Effortless sequence repeat (SSR) data
SSRs enjoy a life threatening part in-plant taxonomy and therefore are widely used once the unit markers [38, 39]. There had been 211–332 SSRs during the for each and every Lythraceae variety one ranged out-of 8 so you’re able to sixteen bp in length (Fig. 5, Extra document 5: Desk S5). Half a dozen categories of SSRs had been found: mononucleotide, di-nucleotide, tri-nucleotide, tetra-nucleotide, penta-nucleotide and you may hexa-nucleotide. But not, hexa-nucleotide repeats was basically seen in just this new cp genomes out-of L. siamica, L. intermedia, T. natans and you will L. salicaria. Among for every single Lythraceae kinds, mononucleotide repeats was indeed typically the most popular, having wide variety ranging from 123 so you can 212; followed by trinucleotide ranging from 56 in order to 68; dinucleotide ranging from sixteen in order to 52; tetranucleotide anywhere between six in order to 12; pentanucleotide anywhere between 0 to dos and you may hexa-nucleotide ranging from 0 to one. (Fig. 5a). It actually was in earlier times unearthed that mono-nucleotide repeats was indeed richest into the Fritillaria, Lilium and Epimedium [twenty-two, 40]. Because of this, mononucleotide repeats can get enjoy a more essential character during the hereditary type compared to almost every other SSRs.
The newest assessment from effortless sequence repeats (SSR) distribution when you look at the twenty-two chloroplast genomes. a number of different SSR sizes perceived within the twenty two chloroplast genomes; b Frequency regarding common design about 22 chloroplast genomes; c Regularity away from SSRs about LSC, IR, SSC region; d Frequency regarding SSRs about intergenic nations, protein-programming genes and introns
Regarding the twenty-two Lythraceae species, A/T mononucleotide repeats taken into account and you will %, correspondingly.
