Abstract Whole-genome duplication (WGD), or polyploidy, events are widespread and significant in the evolutionary history of angiosperms. However, empirical evidence for rediploidization, major process where polyploids give rise to diploid descendants, is still lacking at genomic level. Here we present chromosome-scale genomes mangrove tree Sonneratia alba related inland plant Lagerstroemia speciosa . Their common ancestor has experienced a whole-genome triplication (WGT) approximately 64...
Summary Mangroves have colonised extreme intertidal environments characterised by high salinity, hypoxia and other abiotic stresses. Aegiceras corniculatum , a pioneer mangrove species that has evolved two specialised adaptive traits (salt secretion crypto‐vivipary) is an attractive ecological model to investigate molecular mechanisms underlying adaptation environments. We assembled de novo high‐quality reference genome of A. performed comparative genomic transcriptomic analyses provide...
Abstract In the conventional view, species are separate gene pools delineated by reproductive isolation (RI). an alternative may also be a small set of ‘speciation genes’ without full RI, view that has gained broad acceptance. A recent survey, however, suggested extensive literature on with flow’ is mostly (if not all) about exchanges in early stages speciation. There no definitive evidence observed flow actually happened after speciation completed. Here, we wish to know whether ‘good...
Abstract Although gene loss is common in evolution, it remains unclear whether an adaptive process. In a survey of seven major mangrove clades that are woody plants the intertidal zones daily environmental perturbations, we noticed they generally evolved reduced numbers. We then focused on largest clade Rhizophoreae and observed continual set reduction each eight species. A great majority losses concentrated interaction processes, presumably to cope with constant fluctuations tidal...
Abstract Whole‐genome duplication (WGD) is believed to increase the chance of adaptation a new environment. This conjecture may apply particularly well environments that are not only different but also more variable than ancestral habitats. One such prominent environment interface between land and sea, which has been invaded by woody plants, collectively referred as mangroves, multiple times. Here, we use two distantly related mangrove species ( Avicennia marina Rhizophora apiculata )...
ABSTRACT Nypa fruticans (Wurmb), a mangrove palm species with origins dating back to the Late Cretaceous period, is unique for investigating long‐term adaptation strategies intertidal environments and early evolution of palms. Here, we present chromosome‐level genome sequence assembly N. . We integrated genomes other family members comparative genomic analysis, which confirmed that common ancestor all palms experienced whole‐genome duplication event around 89 million years ago, shaping...
Ecological restoration of mangrove ecosystems that became susceptible to recent habitat perturbations is crucial for tropical coast conservation. The white Laguncularia racemosa, a pioneer species inhabiting intertidal environments the Atlantic East Pacific (AEP) region, has been used reforestation in China decades. However, molecular mechanisms underlying its fast growth and high adaptive potential remain unknown. Using PacBio single-molecule real-time sequencing, we completed high-quality...
Summary Mangrove species are broadly classified as true mangroves and mangrove associates. The latter amphibious plants that can survive in the intertidal zone reproduce naturally terrestrial environments. Their widespread distribution extensive adaptability make them ideal research materials for exploring adaptive evolution. In this study, we de novo assembled two genomes of associates (the allotetraploid Barringtonia racemosa (2 n = 4 x 52) diploid asiatica 2 26)) to investigate role...
Adaptation to new environments is a key evolutionary process which presumably involves complex genomic changes. Mangroves, collection of approximately 80 woody plants that have independently invaded intertidal zones >20 times, are ideal for studying this process. We assembled near-chromosome-scale genomes three Xylocarpus species as well an outgroup using single-molecule real-time sequencing. Phylogenomic analysis reveals two separate lineages, one with the mangrove granatum and other...
SUMMARY Coastal forests, such as mangroves, protect much of the tropical and subtropical coasts. Long‐distance dispersal via sea‐surfing propagules is essential for coastal plants, but genomic molecular basis plant propagule evolution remains unclear. Heritiera fomes littoralis are two plants with typical buoyant fruits. We de novo sequenced assembled their high‐quality genomes. Our phylogenomic analysis indicates H. originated (at ~6.08 Mya) just before start Quaternary sea‐level...
Increased human activity and climate change have significantly impacted wild habitats increased the number of endangered species. Exploring evolutionary history predicting adaptive potential using genomic data will facilitate species conservation biodiversity recovery. Here, we examined genome evolution a critically tree Pellacalyx yunnanensis, plant with extremely small populations (PSESP) that is narrowly distributed in Xishuangbanna, China. The has neared extinction due to economic...
Abstract In the conventional view, species are separate gene pools delineated by reproductive isolation (RI). However, may also be merely a small set of “speciation genes” without full RI. It is thus important to know whether “good species” (defined “secondary sympatry” test) do continue exchange genes. Here, we carry out sequencing and de novo high-quality assembly genomes two closely related mangrove ( Rhizophora mucronata R. stylosa ). Whole-genome re-sequencing individuals across their...
Abstract Mangroves have colonized extreme intertidal environments characterized by high salinity, hypoxia, and other abiotic stresses. During millions of years evolution, mangroves adapted to these habitats, evolving a series highly specialized traits. Aegiceras corniculatum , pioneer mangrove species that evolved salt secretion crypto-vivipary, is an attractive ecological model investigate molecular mechanisms underlying adaptation environments. Here we report high-quality reference genome...
Abstract The biological species concept (BSC) is the prevailing definition of whereby genes cannot be exchanged during or after speciation. In contrast, since only that contribute to adaptive divergence between should non-exchangeable, BSC appears bear little relationship genetic process rejection demands evidence continual gene flow until completion Here, we carry out sequencing and de novo high-quality assembly genomes two closely related mangrove (Rhizophora mucronata R. stylosa)....
