| 摘要 | ‘Breadfruit’ is a common tree species in Taiwan. In the indigenous Austronesian Amis culture
of eastern Taiwan, ‘breadfruit’ is known as Pacilo, and its fruits are consumed as food.
On Lanyu (Botel Tobago) where the indigenous Yami people live, ‘breadfruit’ is called
Cipoho and used for constructing houses and plank-boats. Elsewhere in Taiwan, ‘breadfruit’
is also a common ornamental tree. As an essential component of traditional Yami culture,
Cipoho has long been assumed to have been transported from the Batanes Island of the
Philippines to Lanyu. As such, it represents a commensal species that potentially can be
used to test the hypothesis of the northward Austronesian migration ‘into’ Taiwan. However,
recent phylogenomic studies using target enrichment show that Taiwanese ‘breadfruit’
might not be the same as the Pacific breadfruit (Artocarpus altilis), which was domesticated
in Oceania and widely cultivated throughout the tropics. To resolve persistent misidentification
of this culturally and economically important tree species of Taiwan, we sampled 36
trees of Taiwanese Artocarpus and used the Moraceae probe set to enrich 529 nuclear
genes. Along with 28 archived Artocarpus sequence datasets (representing a dozen taxa
from all subgenera), phylogenomic analyses showed that all Taiwanese ‘breadfruit’ samples,
together with a cultivated ornamental tree from Hawaii, form a fully supported clade within the A. treculianus complex, which is composed only of endemic Philippine species.
Morphologically, the Taiwanese ‘breadfruit’ matches the characters of A. treculianus. Within
the Taiwanese samples of A. treculianus, Amis samples form a fully supported clade derived
from within the paraphyletic grade composed of Yami samples, suggesting a Lanyu origin.
Results of our target enrichment phylogenomics are consistent with the scenario that
Cipoho was transported northward from the Philippines to Lanyu by Yami ancestors, though
the possibility that A. treculianus is native to Lanyu cannot be ruled out completely. |
