“…In T. rupestris , the clustering of the different populations into the two major clades agreed with the geographical distribution and its classification into the two varieties [22, 23]. The moderate degree of gene flow shaped the genetic profiles of T. rupestris , homogenizing the genetic diversity of the two varieties, namely, T. rupestris var.…”

“…In Opisthopappus , not only at genus level but also at species level, there was high genetic diversity. Nei's genetic diversity and Shannon's information index of O. taihangensis (Ling) Shih and O. longilobus Shih were higher than those of herbaceous plants ( H = 0.162, I = 0.238) and plants in narrow fields or endangered plants ( H = 0.157, I = 0.249) [ 36 , 37 ] but were slightly lower than those of Taihangia rupestris , another cliff species endemic to the same area [ 22 , 23 ]. These indicated that two species of Opisthopappus both had higher genetic diversity.…”

Opisthopappus Shih is endemic to the Taihang Mountains, China. It grows in the crevice of cliffs and is in fragmented distribution. This genus consists of two species, namely, O. taihangensis (Ling) Shih and O. longilobus Shih, which are both endangered plants in China. This study adopted intersimple sequence repeat markers (ISSR) to analyze the genetic diversity and genetic structure from different levels (genus, species, and population) in this genus. A total of 253 loci were obtained from 27 primers, 230 of which were polymorphic loci with a proportion of polymorphic bands (PPB) of up to 90.91% at genus level. At species level, both O. taihangensis (PPB = 90.12%, H = 0.1842, and I = 0.289) and O. longilobus (PPB = 95.21%, H = 0.2226, and I = 0.3542) have high genetic diversity. Their respective genetic variation mostly existed within the population. And genetic variation in O. longilobus (84.95%) was higher than that in O. taihangensis (80.45%). A certain genetic differentiation among populations in O. taihangensis was found (G st = 0.2740, Φst = 0.196) and genetic differentiation in O. longilobus was very small (G st = 0.1034, Φst = 0.151). Gene flow in different degrees (N m = 1.325 and 4.336, resp.) and mating system can form the existing genetic structures of these two species. Furthermore, genetic differentiation coefficient (G st = 0.0453) between species and the clustering result based on the genetic distance showed that interspecific differentiation between O. taihangensis and O. longilobus was not significant and could occur lately.

“…Genomic DNA (30 μg) was extracted from silica gel-dried leaves of a single individual of P. kawakamii using the modified CTAB method (Wang et al, 2011) and digested with RsaI and XmnI enzymes. The digested DNA was linked to forward (5ꞌ-GTTTAAGGCCTAGCTAGCAGA ATC-3ꞌ) and reverse (5ꞌ-pGATTCTGCTAGCTAGGCCTTAAACAAAA-3ꞌ) adapters using 2 units of T4 DNA ligase.…”

ABSTRACT. Paulownia kawakamii is a fast-growing timber tree. In this study, 21 primer sets were developed using an enriched genomic library. The genetic diversity was measured in one P. kawakamii population. The number of alleles per locus ranged from 2 to 19. The observed and expected heterozygosities varied from 0.158 to 0.842 (mean = 0.421) and from 0.376 to 0.952 (mean = 0.771), respectively. All 21 loci were also polymorphic in closely related species (P. tomentosa, P. elongata, and P. fortunei). The described markers will be useful in future population genetic studies and molecular breeding of these Paulownia species.
