FIGURE 5 in Asymmetric hybridization origin of Rhododendron agastum (Ericaceae) in Guizhou, China
FIGURE 5. Genotype class assignment of representative individuals of Rhododendron delavayi, R. irroratum, and R. agastum from the Baili Rhododendron Reserve of Guizhou Province, China. All the samples are represented as a vertical bar partitioned into segments; whose length is proportional to the likelihood of belonging to a certain class. F 1 represents the first hybrid speciation; F 2 represents the second hybrid speciation, and BC represents backcross.

FIGURE 2. PCoA based on SSR data of all representative individuals of Rhododendron delavayi, R. decorum, R. irroratum, and R. agastum from the Baili Rhododendron Reserve of Guizhou Province, China.
FIGURE 1 in Asymmetric hybridization origin of Rhododendron agastum (Ericaceae) in Guizhou, China
FIGURE 1. Comparison of the four Rhododendron species, namely Rhododendron decorum, R. irroratum, R. agastum and R. delavayi in the Baili Rhododendron Reserve of Guizhou Province, China. a, d, g and j: Flowers; b, e, h and k: Adaxial surface of leaves; c, f, i and l: Abaxial surface of leaves.
FIGURE 6 in Asymmetric hybridization origin of Rhododendron agastum (Ericaceae) in Guizhou, China
FIGURE 6. Haplotype networks from the three representative species in the Baili Rhododendron Reserve of Guizhou Province, China.
FIGURE 3 in Asymmetric hybridization origin of Rhododendron agastum (Ericaceae) in Guizhou, China
FIGURE 3. Genetic STRUCTURE of representative individuals of Rhododendron delavayi, R. decorum, R. irroratum, and R. agastum from the Baili Rhododendron Reserve of Guizhou, China based on SSR data. K value of the best classification group was analysed based on Delta K.
FIGURE 4 in Asymmetric hybridization origin of Rhododendron agastum (Ericaceae) in Guizhou, China
FIGURE 4. Approximate Bayesian Computation Analysis of parental origin of Rhododendron agastum based on SSR data using DIYABC software. Time in generations was t (T3 ≥ T2 ≥ Ta). a Scenario 1 (R. agastum is the natural hybrid between R. delavayi and R. irroratum); c Scenario 2 (R. agastum is the natural hybrid between R. delavayi and R. decorum); b, d Posterior probabilities.
Data from: Tracing the origin of Oriental beech stands across Western Europe and reporting hybridization with European beech – implications for assisted gene flow
<p>The benefits and risks of human-aided translocation of individuals within the species range, assisted gene flow (AGF), depend on the genetic divergence, on the rate and direction of hybridization, and on the climate transfer distance between the host and donor populations. In this study, we explored the use of Oriental beech (<em>Fagus</em> <em>sylvatica</em> subsp. <em>orientalis</em>), growing from Iran to the Balkans, for AGF into European beech populations (<em>F</em>. <em>sylvatica</em> subsp. <em>Sylvatica</em>) that increasingly suffer from climate warming. Using samples from natural populations of Oriental and European beech and microsatellite loci, we identified 5 distinct genetic clusters in Oriental beech with a divergence (FST) of 0.15 to 0.25 from European beech. Using this knowledge, we traced the origin of 11 Oriental beech stands in Western Europe established during the 20<sup>th</sup> century. In two stands of Greater Caucasus origin, we found evidence for extensive hybridization, with 18% and 41% of the seedlings having hybrid status. Climate data revealed higher seasonality with warmer and drier summers across the native Oriental beech sites in comparison to the planting sites in Western Europe. Accordingly, we found that bud burst of Oriental beech occurred four days earlier than in European beech. Overall, our results suggest that AGF of Oriental beech could increase the genetic diversity of European beech stands and may foster introgression of variants adapted to expected future climatic conditions. Our study showcases the evaluation of the benefits and risks of AGF and call for similar studies on other native tree species.</p>
