“…papyrifera samples from Polynesia, Southeast Asia and East Asia, we analysed non-coding internal transcribed spacer (ITS) sequences of nuclear ribosomal DNA, and inter-simple sequence repeat (ISSR) sequences in total DNA extracts. Diversity was found in Asia and not in Polynesia [ 14 ], with the sole exception of Hawaii [ 15 ]. The data suggested a prehistoric human-mediated movement of paper mulberry from East Asia to Polynesia, by an unknown route through island Southeast Asia, and a second, possibly historic, human-mediated introduction to Hawaii [ 15 ].…”

Sex Distribution of Paper Mulberry (Broussonetia papyrifera) in the Pacific

BackgroundPaper mulberry (Broussonetia papyrifera (L.) L'Hér. ex Vent) is a dioecious tree native to East Asia and mainland Southeast-Asia, introduced prehistorically to Polynesia as a source of bark fiber by Austronesian-speaking voyagers. In Oceania, trees are coppiced and harvested for production of bark-cloth, so flowering is generally unknown. A survey of botanical records of paper mulberry revealed a distributional disjunction: the tree is apparently absent in Borneo and the Philippines. A subsequent study of chloroplast haplotypes linked paper mulberry of Remote Oceania directly to a population in southern Taiwan, distinct from known populations in mainland Southeast-Asia.MethodologyWe describe the optimization and use of a DNA marker designed to identify sex in paper mulberry. We used this marker to determine the sex distribution in selected localities across Asia, Near and Remote Oceania. We also characterized all samples using the ribosomal internal transcribed spacer sequence (ITS) in order to relate results to a previous survey of ITS diversity.ResultsIn Near and Remote Oceania, contemporary paper mulberry plants are all female with the exception of Hawaii, where plants of both sexes are found. In its natural range in Asia, male and female plants are found, as expected. Male plants in Hawaii display an East Asian ITS genotype, consistent with modern introduction, while females in Remote Oceania share a distinctive variant.ConclusionsMost paper mulberry plants now present in the Pacific appear to be descended from female clones introduced prehistorically. In Hawaii, the presence of male and female plants is thought to reflect a dual origin, one a prehistoric female introduction and the other a modern male introduction by Japanese/Chinese immigrants. If only female clones were dispersed from a source-region in Taiwan, this may explain the absence of botanical records and breeding populations in the Philippines and Borneo, and Remote Oceania.

Abbreviations F = Farmland; FU = Forest understorey; LGB = Large canopy gaps dominated by Broussonetia papyrifera; LGC = Large canopy gaps dominated by Chromolaena odorata; LR = Logging road; MAP = Mansonia altissima plantation; MDT = Modified Taungya System; NDP = Nauclea diderrichii plantation; NPLD = Non-pioneer light-demander; P = Pioneer; SB = Shade-bearer; ST = Skid trail; TIP = Terminalia ivorensis plantation. Abstract Question: Does the invasive tree species Broussonetia papyrifera facilitate the natural regeneration of native tree species in a degraded tropical forest landscape? Location: Afram Headwaters Forest Reserve, southern Ghana.Methods: We established sampling areas and assessed seedlings and saplings <5 cm DBH in nine habitats. The habitats were logging road, skid trail, large canopy gaps dominated by B. papyrifera, large canopy gaps dominated by invasive Chromolaena odorata, Nauclea diderrichii plantation, Mansonia altissima plantation, Terminalia ivorensis plantation, abandoned farmland and unlogged forest.Results: We found that the abundance of pioneers declined with increasing abundance of B. papyrifera. This trend was more pronounced in the farmland and in the N. diderrichii plantation. By contrast, increased abundance of B. papyrifera did not lead to a decrease in the abundance of the shade-tolerant species. B. papyrifera seedlings and saplings were absent in the forest understorey. We also found a lower abundance and richness of some vulnerable tree species and valuable timber species in the N. diderrichii plantation and in gaps dominated by B. papyrifera. However, we recorded both shade-tolerant and shade-intolerant species in the gaps dominated by B. papyrifera. Conclusions:We found both shade-tolerant and shade-intolerant species in the B. papyrifera-dominated gaps. This can provide a basis for future studies to explore the potential of such tree species in restoration programmes targeted at B. papyrifera-invaded sites. Our results also suggest that the integrity of the undisturbed forest patches in the landscape must be protected to help prevent B. papyrifera from spreading further. We suggest further studies should be conducted at replicated sites with a similar habitat that represent varying levels of invasion by B. papyrifera to draw conclusions regarding the species' potential to facilitate regeneration of native tree species.

“…The genetic diversity of B. papyrifera has been studied using intersimple sequence repeat (ISSR) markers ( Ho and Chang, 2006 ; Liao et al, 2014 ; González-Lorca et al, 2015 ), sequence-related amplified polymorphism (SRAP) markers ( Liu et al, 2009 ), hypervariable chloroplast DNA (cpDNA) sequences, and internal transcribed spacer (ITS) sequences of ribosomal DNA ( Chang et al, 2015 ). These molecular markers have been useful for characterizing the genetic diversity and population structure of this species within its native range.…”

“…These molecular markers have been useful for characterizing the genetic diversity and population structure of this species within its native range. However, studies using ITS sequences and ISSR data ( Seelenfreund et al, 2011 ; Gonzalez-Lorca et al, 2015 ) and a sex marker ( Peñailillo et al, 2016 ) in B. papyrifera in the introduced range in the Pacific region have not provided the resolution to understand its dispersal across this geographic area where it has been propagated asexually ( Peñailillo et al, 2016 ). Therefore, the development of microsatellite markers is crucial to genotype the species’ genetic diversity in Japan and the Pacific region.…”

Premise of the study:Broussonetia papyrifera (Moraceae) is native to Asia and is used as a medicinal plant and as a source of fiber for making paper. It was dispersed into the Pacific region as a fiber source for making nonwoven textiles (barkcloth). Microsatellites were developed to trace the human-mediated dispersal of this species into the Pacific region.Methods and Results:A set of 36 microsatellites was isolated and initially assayed on 10 accessions to assess polymorphism. We found that 20 markers were polymorphic, with the number of alleles per marker ranging from four to 35 in 70 accessions genotyped from three Asian populations. Observed and expected heterozygosities ranged from 0.04 to 0.85 and from 0.19 to 0.94, respectively. These markers were tested in four Moraceae species and one Rosaceae species.Conclusions:These markers will be useful for the assessment of genetic diversity in B. papyrifera. They show low transferability to other species tested.
