The Distribution and Origins of Pyrus hopeiensis-"Wild Plant With Tiny Population" Using Whole Genome Resequencing.

ABSTRACT: Pyrus hopeiensis is a valuable but endangered wild resource in the genus Pyrus. It has been listed as one of the 120 wild species with tiny population in China. The specie has been little studied. A preliminary study of propagation modes in P. hopeiensis was performed through seed propagation, hybridization, self-crossing trials, bud grafting, branch grafting, and investigations of natural growth. The results showed that the population size of P. hopeiensis was very small, the distribution range was limited, and the habitat was extremely degraded. In the wild population, natural hybridization and root tiller production were the major modes of propagation. Whole genome re-sequencing of the 23 wild and cultivated accessions from Pyrus species collected was
