“…Since then, several other phylogenetic studies on Dipterocarpaceae were reported based on chloroplast (cp) DNA sequences Gamage et al, 2003;Kajita et al, 1998;Kamiya et al, 1998;Morton et al, 1999) and the nuclear gene PgiC (Kamiya et al, 2005). However, previous studies on molecular phylogeny of the Dipterocarpaceae included either limited number of species Morton et al, 1999;Tsumura et al, 1996) or informative sites (Gamage et al, 2003;Kamiya et al, 1998) or both . The most recent work by Kamiya et al (2005) has mainly focused on the relationships of Shorea , Hopea, Neobalanocarpus and Parashorea genera and did not include species from the Dipterocarpeae tribe and species of the Doona genus (Kostermans, 1984;Kostermans, 1992;Maury, 1978;Maury-Lechon, 1979).…”

Dipterocarpoideae, the largest sub-family of well-known plant family Dipterocarpaceae, dominates in South Asian rain forests. Although several previous studies addressed the phylogeny of the Dipterocarpaceae family, relationships among many of its genera from the Dipterocarpoideae sub-family are still not well understood. In particular, little is known about the relationships of the genera Vateriopsis , Stemonoporus , Vateria and inconsistence remains between phylogenetic results and taxonomic classifications of Shorea and Hopea species. We studied molecular phylogeny of the sub-family Dipterocarpoideae using the trnL-trnF spacer, trnL intron and the matK gene sequences of chloroplast DNA (cpDNA). This study is the first comprehensive phylogeny reconstruction for the sub-family Dipterocarpoideae based on cpDNA, as it includes most genera (14) and a large number of species (79) with most species endemic to Sri Lanka, as well as one species from Seychelles and one species from the genus Monotes from Madagascar. Phylogenetic trees were constructed using the Neighbor Joining (NJ) and Maximum Likelihood (ML) methods using combined set of sequences including all three cpDNA regions. The topologies of the NJ and ML trees were to a certain extent, consistent with the current taxonomy of Dipterocarpoideae based on morphology and with previous molecular phylogenies based on cpDNA. Furthermore, our results provided new evidence regarding the relationships of the following genera: Vateriopsis and Stemonoporus and about the validity of the previous morphology based classifications of Shorea species. In addition, the topology of our trees was consistent with the classification of Shorea species proposed by Maury (1978), Maury-Lechon (1979) and Symington (1943). Finally, our results provided evidence for the affinity of the genus Monotes to Asian Dipterocarpoideae rather than to Tiliaceae and indicated that it is a good candidate for outgroup species for future studies of the former sub-family.

Phylogenomics and a revised tribal classification of subfamily Dipterocarpoideae (Dipterocarpaceae)

Dipterocarpoideae, the largest subfamily in the Meranti family (Dipterocarpaceae) are an ecologically dominant group of trees throughout much of wet tropical Asia. Increasing anthropogenic pressures on this economically important tree family make it essential to resolve their complex evolutionary relationships and understand the distribution of genetic diversity throughout the family and distribution range. Dipterocarpaceae have been the focal group in a wide range of studies, owing to their economic value, importance in historical biogeography and key role in the evolution of the Asian tropical forest biome. Despite this, persistent taxonomic and evolutionary questions remain, ranging from questions on the geographic origin, sequence of dispersal and the identification of diagnostic characters to circumscribe proper evolutionary groups. Here we present a comprehensive phylogenomic hypothesis for Dipterocarpoideae, based on the analyses of plastome and nuclear cistron (NRC) data, and provide an in‐depth review on the validity of morphological characters underlying the new tribal classification proposed here for the subfamily. Phylogenomic relationships were inferred using maximum likelihood and Bayesian approaches. Estimates of origin and onset of diversification in major clades and lineages were reconstructed using plastome, nuclear and combined datasets. Results of the separate and combined genomic datasets partly corroborate elements of previous classification systems (with improved support at all levels for major clades) but provide strong support for revising the tribal classification of the subfamily into four main clades: Dipterocarpeae (Dipterocarpus), Dryobalanopseae (Dryobalanops), Shoreeae (Hopea, Neobalanocarpus, Parashorea, and all parts of a polyphyletic Shorea) and Vaterieae (including all other presently accepted Dipterocarpoideae genera). Multi‐fossil‐dated divergence time estimation suggests Vaterieae first originated in the Late Cretaceous, followed by Dipterocarpeae, with subsequent rise of the Dryobalanopseae and Shoreeae in the Eocene. Diversification of all tribes commenced before the Early Miocene. Our results provide strong support for the position of Neobalanocarpus heimii, Parashorea and (sub‐)sections of the genera Anisoptera, Hopea, Shorea and Vatica. Hypotheses on the origin of Neobalanocarpus heimii by intergeneric hybridisation between Anthoshorea (maternally inherited) and Hopea (paternally inherited) species were corroborated. Finally, our study provides support for future revisionary changes: (1) the elevation to generic rank of sections in Shorea; and (2) revising the infrageneric classification of Hopea as all (sub‐)sections were recovered as not monophyletic.

It has been hypothesized that most Asian tropical lineages have originated in Gondwana with the Indian subcontinent playing a crucial role in the dispersal of ancestral Gondwanan taxa. The disjunct distribution of dipterocarps and the fossil record in India support the Gondwana hypothesis. This is the first comprehensive study addressing the evolutionary and biogeographic relationships of dipterocarps in the Indian subcontinent to test the Gondwana hypothesis. A Bayesian phylogenetic tree of the Dipterocarpaceae family including the Indian counterparts corroborates the monophyly of subfamilies/tribes and shows new biogeographic affinities. Molecular dating reveals the Cretaceous origin of Dipterocarpaceae. Diversification of major lineages occurred during the Pliocene-Miocene epochs. The DEC analysis ascertains the Gondwanan origin and dispersal route from the Madagascar (Africa)-India-Sri Lanka-Seychelles block to Eurasia. The biogeographic analysis suggests early vicariance followed by an outof-India dispersal of Dipterocarpaceae. Three dispersal events from India to the remainder of Asia at 47.6 Ma, 42.53 Ma and 37.6 Ma are identified. There probably was a biotic interchange between India and mainland Asia via Sumatra following the collision of the Indian plate with Eurasia. Molecular dating and dispersal events coincide with the geological events. During the Miocene, uplift of the Himalayan-Tibetian plateau induced climatic variation, which seems to have resulted in the extinction of major Indian dipterocarp lineages and reverse dispersal into India. Hopea-Shorea, one of the earliest diverged lineages, originated in Southeast Asia. The establishment of Southeast Asian monsoon climate may have favoured allopatric speciation and diversification of Southeast Asian lineages also resulting in further dispersal into India.
