    ABSTRACT

    Populations in extreme environments at the margins of a species' range are often the most vulnerable to climate change, but they may also experience novel evolutionary processes, such as secondary contact and hybridization with their relatives. The range overlap resulting from secondary contact with related species that have adapted to different climatic zones may act as corridors for adaptive introgression. To test this hypothesis, we examined the hybrid zones along the altitude of two closely related Rubus species, one temperate and the other subtropical species, at their southern and northern limits on Yakushima Island, Japan. Genomic cline analysis revealed non‐neutral introgression throughout the genome in both directions in the two species. Some of these genomic regions involve gene ontology terms related to the regulation of several biological processes. Our niche modeling suggests that, assuming niche conservatism, the temperate species are likely to lose their suitable habitat, and the backcrossed hybrids with the subtropical species are already expanding upslope on the island. Adaptive introgression through the hybrid zone may contribute to the persistence and expansion of the species in the southernmost and northernmost populations.

    Abstract

    Wild relatives of cultivars are crucial sources of genetic variation for further enhancement, yet they face potential threats due to contemporary environmental changes. Iris ensata var. spontanea, a wild progenitor of the Japanese iris cultivars (I. ensata var. ensata), is extensively cultivated in Japanese gardens, is distributed across mesic meadows and wetlands in Japan and East Asia. This species is currently threatened owing to habitat loss linked to land use alterations. We assessed genetic diversity and phylogenetic relationships in 32 wild accessions and the 14 principal Edo Group of Japanese iris cultivars, originally bred during the Edo period (1600–1868). In the phylogenetic tree, the cultivars formed a cluster with low inbreeding coefficients, suggesting a singular origin and interbreeding between the genetically distinct accessions. Conversely, wild accessions exhibited greater overall genetic diversity and higher inbreeding coefficients than cultivars, indicating frequent inbreeding within divergent natural populations. Our findings highlight the distinct genetic reservoirs of both wild accessions and Edo cultivars, although the former may face inbreeding challenges. Urgent conservation action is needed to ensure the genetic diversity of wild populations as natural resources.
