“…For our work, among 33,974 assembled unigene sequences, 2644 potential EST-SSRs were identified, which represented ∼7.78% of the transcriptomic sequences ( Supplementary Table S2), and the distribution density was one SSR per 10.30 kb. The SSRs frequency and distribution density were higher than some species, such as Argyranthemum broussonetii (2.3%, 27 kb) (White et al, 2016) and Zingiber officinale (2.7%, 25.2 kb) (Awasthi et al, 2017), and lower than Arachis hypogaea (17.7%, 3.3 kb) (Wang et al, 2018), Curcuma longa (14.6%, 5.3 kb; 14.9%, 5.2 kb; 20.5%, 4.8 kb) (Annadurai et al, 2013), and Curcuma alismatifolia (12.5%, 6.6 kb) (Taheri et al, 2019). Differences in the frequency of SSRs in ESTs could be partially attributed to the different genetic basis of various plant species, the size of the unigene assembly dataset, SSR search criteria, sequence redundancy, as well as the mining tools utilized (Kumpatla and Mukhopadhyay, 2005;Chen et al, 2015;Wei et al, 2016;Liu et al, 2018;Taheri et al, 2019).…”
