Origin of Livistona chinensis var. subglobosa (Arecaceae) on the “islet of the gods”: Aoshima, Japan

Abstract

RAPD analysis was performed to discuss the origin of Livistona chinensis var. subglobosa using samples from eight localities, Iriomotejima, Ishigakijima, Okinawa, Yakushima, Tanegashima, Cape Sata, Tsukishima, and Aoshima, in Japan. Random amplified polymorphic DNA (RAPD) markers were obtained using five random primers and analyzed by the unweighted pair group method arithmetic (UPGMA). Data from Iriomotejima clustered with data from Aoshima, suggesting the possibility that seeds or green woods were carried by the tidal current from the southern fields of Iriomotejima to Aoshima.

Intraspecific karyotypic polymorphism is highly concordant with allozyme variation in Lysimachia mauritiana (Primulaceae: Myrsinoideae) in Taiwan: implications for the colonization history and dispersal patterns of coastal plants

“…Coastal plant species may differ from other terrestrial taxa because of their hydrochorous habit, wide geographic range and linear distribution along the coastal lines (Kadereit et al, 2005). Recent DNA marker-based studies of coastal plants have found taxa with both strong (Yoshida, 2000;Kadereit et al, 2005;Matsumura, 2009) and weak (Arafeh and Kadereit, 2006;Takayama et al, 2006) phylogeographic structuring. Kadereit and Westberg (2007) suggested that glacial histories, abiotic factors such as oceanic currents, and species-specific biology have all interwoven to yield their phylogeographic structures.…”

“…For coastal and maritime floras, the KC had long been hypothesized to have brought the tropical elements suitable for dissemination by sea to the subtropical islands of the Ryukyus (Nakanishi, 1988;Kuo et al, 2006). These conjectures have been supported by molecular data recently (Yoshida et al, 2000;Matsumura et al, 2009). However, to our knowledge, the impacts of the KC on coastal plants in Taiwan have rarely been addressed in the recent literature.…”

Further species within Arecaceae (Palmae; Coryphoideae) to non-native flora of Tunisia and North Africa

“…Notes on general distribution: L. chinensis is native to Eastern Asia including China, Japan (i.e., Ryukyu Islands, Bonin Islands) and Taiwan (Horikawa 1972, Suzuki 1982, Yoshida et al 2000, USDA-ARS 2016. The species is widely cultivated as an ornamental and can be found naturalized in the West Indies, tropical America and on many islands in the Indian and Pacific Oceans (Wagner et al 1999, Meyer et al 2008, Flora of China Editorial Committee 2016, Govaerts 2016, PIER 2016.…”

Development and characterization of 20 polymorphic microsatellite markers for Livistona chinensis R. Br. var. subglobosa Becc., a fan palm in the Ryukyu Archipelago, Japan

“…A similar establishment of remote populations based on cultural uses by ancient people was also reported in a close relative, Livistona mariae , an endemic fan palm in arid central Australia (Kondo et al ; Bowman et al ). Although these hypotheses were examined with one remote population by random amplified polymorphic DNA (RAPD) analysis (Yoshida et al ), it remains unclear how remote populations became established in such regions because of the limited number of analyzed populations and the low level of polymorphism in RAPD analysis.…”
