“…The wide distribution of B. multangula, like that of other members of the Sphenanthera section, for example, B. longifolia, could be due to its broad ecological tolerance and the greater possibility of long-distance dispersal afforded by baccate and therefore probably dispersed in animals. Such variations of Begonia are dominantly caused by population isolation (Tebbitt 2003). Population-level variations are consistent with macroevolution in the genus Begonia (Hughes and Hollingsworth 2008).…”

Abstract. Warseno T, Efendi M, Chasani AR, Daryono BS. 2022. Genetic variability and phylogenetic relationships of Begonia multangula based on atpB-rbcL non-coding spacer of cpDNA sequences. Biodiversitas 23: 5491-5501. Begonia (Begoniaceae) belongs to Section Platycentrum-Sphenanthera Group which has a wide distribution from Sumatra to the Lesser Sunda Islands and Sulawesi. Information on B. multangula genetic variability and intraspecies relationships based on molecular characters is critical for developing appropriate strategies in conservation biology, breeding activities, and many other applied fields. The genetic variability and interspecific relationships of B. multangula in Indonesia were investigated using sequence data from the atpB-rbcL intergenic spacer (IGS) cpDNA regions. The atpB-rbcL IGS fragment was amplified using atpB-1 as the forward primer and rbcL-1 as the reversed primer. Genetic variations were found in the length of the sequence and nucleotide divergences in the atpB-rbcL IGS region. The genetic distance between 822 fixed sites ranged from 0 to 0.61%. Eighteen of the 822 sites (99.27%) analyzed were invariable, six sites (0,73%) were variable consisting of 4 singleton variable sites and two parsimony informative sites, and twelve sites were gaps. The phylogenetic relationships generated by B. multangula based on the atpB-rbcL IGS sequence analysis indicated the genetic variation and divided it into two clades. However, the clustering pattern of B. multangula specimens resulting from molecular analysis based on atpB-rbcL IGS sequences did not show the geographic clustering grouping pattern.

“…Only a small proportion of species are known to be widespread (e.g. B. longifolia Blume; Tebbitt, 2003) or adapted to grow in different habitats, notably the African seasonally‐adapted Begonia (25 species; Plana, 2003). Begonia is informally divided into African, American, and Asian continental groups, each of which comprise 17–29 sub‐generic sections and a few orphan species (Doorenbos et al ., 1998; Shui, Peng & Wu, 2002; de Wilde & Plana, 2003; Forrest & Hollingsworth, 2003; Gu, Peng & Turland, 2007).…”

Begonia L. is one of the largest flowering plant genera, a ubiquitous component of many tropical forests and an economically important ornamental plant. In the present study, we address the early evolution of Begonia by generating molecular phylogenies from approximately 7000 bases of chloroplast DNA and approximately 6000 bases of mitochondrial DNA for each of 30 exemplar Begonia species. Broadscale biogeographic patterns found in the phylogenies, together with previously estimated divergence dates, indicated that extant Begonia lineages first diversified in Africa and then subsequently in America and Asia. The phylogenies also revealed that the closest African relatives of the American and Asian Begonia are seasonally-adapted species. Moderate to strong incongruence between the phylogenies suggested that they differ genealogically. These differences could have been the result of either interspecific hybridization and/or incomplete lineage sorting. The results obtained in the present study provide a much needed genus-wide framework for future evolutionary studies of this exceptionally diverse tropical genus.

“…The distance between Bali and Lombok is near, while B. longifolia has a very wide distribution. The type of fruit and seed structure allows animals and wind to help its distribution (Tebbitt, 2003). These might be the factors that B. longifolia in Bali and Lombok are similar based on molecular characters.…”

Abstract.Ningrum WDA, Atmaja MB, Daryono BS, Purnomo. 2020. Genetic variability of Begonia longifolia Blume from Indonesia based on Nuclear DNA internal transcribed spacer (ITS) sequence data. Biodiversitas 21: 5778-5785. Begonia longifolia Blume is a member of the Begoniaceae family which has the widest distribution in Asia including Indonesia. Diversity studies on B.longifolia from Indonesia were mainly based on morphological characters. The genetic diversity analysis of this pantropical species in Indonesia has never been reported yet. This research aimed to study genetic variability of B. longifolia in Indonesia based on nuclear DNA internal transcribed spacer (ITS) sequence data. Twelve living specimens were from Sumatra (Lampung), Java (Sukabumi, Purwokerto), Bali (Buleleng, Gianyar, Jembrana, Tabanan), and Lombok. The 831-839 length sequence was aligned using Mesquite software. Reconstruction of the phylogenetic tree was done by MEGA7 software using Neighbor-Joining method with Kimura-2-Parameter. The 827 fixed sites showed a genetic distance ranged from 0 to 1.6%. Among the 827 sites compared, 802 sites were invariable, 19 sites were variable (11 singleton variable sites and 8 parsimony informative sites) and 6 sites were gaps. The phylogenetic tree showed 1 clade and 6 sub-clades. Specimens from Sumatra and Java formed a single sub-clade, separate with five sub-clades from Bali. Specimen from Lombok belong to one of the sub-clades of the Bali specimens. All specimens can be divided into 2 groups: Sumatra-Java and Bali-Lombok group.
