Abstract
Alisma L. is a genus of aquatic and wetland plants belonging to family Alismataceae. At present, it is thought to contain ten species. Variation in ploidy level is known in the genus, with diploids, tetraploids and hexaploids recorded. Previous molecular phylogenetic studies of Alisma have generated a robust backbone that reveals important aspects of the evolutionary history of this cosmopolitan genus, yet questions remain unresolved about the formation of the polyploid taxa and the taxonomy of one particularly challenging, widely distributed species complex. Here we directly sequenced, or cloned and sequenced, nuclear DNA (nrITS and phyA) and chloroplast DNA (matK, ndhF, psbA-trnH and rbcL) of multiple samples of six putative species and two varieties, and conducted molecular phylogenetic analyses. Alisma canaliculatum and its two varieties known in East Asia and A. rariflorum endemic to Japan possess closely related but heterogeneous genomes, strongly indicating that the two species were generated from two diploid progenitors, and are possibly siblings of one another. This evolutionary event may have occurred in Japan. Alisma canaliculatum var. canaliculatum is segregated into two types, each of which are geographically slightly differentiated in Japan. We reconstructed a single phylogeny based on the multi-locus data using Homologizer and then applied species delimitation analysis (STACEY). This allowed us to discern A. orientale as apparently endemic to the Southeast Asian Massif and distinct from the widespread A. plantago-aquatica. The former species was most likely formed through parapatric speciation at the southern edge of the distribution of the latter.

DOKLADY BIOLOGICAL SCIENCES : PROCEEDINGS OF THE ACADEMY OF SCIENCES OF THE USSR, BIOLOGICAL SCIENCES SECTIONS 2022; 506:172-178.

Abstract
Field observations of flowering Alisma plantago-aquatica plants were carried out in Moscow region (Russia). The A. plantago-aquatica flower remains anthetic for a single light day, from 9:00 a.m. to 8:00 p.m. White petals showed a contrast bicolored pattern in UV light, and the pattern probably serves as a nectar clue for pollinators. Flowers were visited by insects in daytime from 11:00 a.m. to 3:00 p.m. Coleopterans (Coccinellidae), dipterans (Drosophilidae, Hybotidae, Muscidae, Sepsidae, and Syrphidae), and hymenopterans (Apidae) were observed as flower visitors. Hoverflies (Syrphidae) and bees (Apidae) were the most frequent visitors. Large amounts of A. plantago-aquatica pollen grains were found on their bodies, and a major role in pollination was consequently assumed for the insects. Based on the original findings and literature data on A. plantago-aquatica reproductive biology in Belgium, Slovakia, and the Czech Republic, hoverflies were identified as the most stable and efficient pollinators of A. plantago-aquatica in various parts of the species range. Bees (Apidae) were recognized as A. plantago-aquatica pollinators for the first time in this work. A flower isolation experiment confirmed that A. plantago-aquatica is a self-compatible plant, but requires insects for the most efficient cross-pollination.

An overlooked dispersal route of Cardueae (Asteraceae) from the Mediterranean to East Asia revealed by phylogenomic and biogeographical analyses of Atractylodes. ANNALS OF BOTANY 2022; 130:53-64. [PMID: 35533344 PMCID: PMC9295924 DOI: 10.1093/aob/mcac059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Accepted: 05/06/2022] [Indexed: 05/11/2023]
Abstract
BACKGROUND AND AIMS The East Asian-Tethyan disjunction pattern and its mechanisms of formation have long been of interest to researchers. Here, we studied the biogeographical history of Asteraceae tribe Cardueae, with a particular focus on the temperate East Asian genus Atractylodes DC., to understand the role of tectonic and climatic events in driving the diversification and disjunctions of the genus. METHODS A total of 76 samples of Atractylodes from 36 locations were collected for RAD-sequencing. Three single nucleotide polymorphism (SNP) datasets based on different filtering strategies were used for phylogenetic analyses. Molecular dating and ancestral distribution reconstruction were performed using both chloroplast DNA sequences (127 Cardueae samples) and SNP (36 Atractylodes samples) datasets. KEY RESULTS Six species of Atractylodes were well resolved as individually monophyletic, although some introgression was identified among accessions of A. chinensis, A. lancea and A. koreana. Dispersal of the subtribe Carlininae from the Mediterranean to East Asia occurred after divergence between Atractylodes and Carlina L. + Atractylis L. + Thevenotia DC. at ~31.57 Ma, resulting in an East Asian-Tethyan disjunction. Diversification of Atractylodes in East Asia mainly occurred from the Late Miocene to the Early Pleistocene. CONCLUSIONS Aridification of Asia and the closure of the Turgai Strait in the Late Oligocene promoted the dispersal of Cardueae from the Mediterranean to East China. Subsequent uplift of the Qinghai-Tibet Plateau as well as changes in Asian monsoon systems resulted in an East Asian-Tethyan disjunction between Atractylodes and Carlina + Atractylis + Thevenotia. In addition, Late Miocene to Quaternary climates and sea level fluctuations played major roles in the diversification of Atractylodes. Through this study of different taxonomic levels using genomic data, we have revealed an overlooked dispersal route between the Mediterranean and far East Asia (Japan/Korea) via Central Asia and East China.

AMERICAN JOURNAL OF BOTANY 2022; 109:1004-1015. [PMID: 35567497 DOI: 10.1002/ajb2.1865] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/12/2021] [Revised: 04/18/2022] [Accepted: 04/19/2022] [Indexed: 06/15/2023]
Abstract
PREMISE Pollinator sharing of co-flowering plants may result in interspecific pollen receipt with a fitness cost. However, the underlying factors that determine the effects of heterospecific pollen (HP) are not fully understood. Moreover, the cost of stigma closure induced by HP may be more severe for plants with special touch-sensitive stigmas than for plants with non-touch-sensitive stigmas. Very few studies have assessed HP effects on stigma behavior. METHODS We conducted hand-pollination experiments with 10 HP donors to estimate HP effects on stigma behavior and stigmatic pollen germination in Campsis radicans (Bignoniaceae) at low and high pollen loads. We assessed the role of phylogenetic distance between donor and recipient, pollen size, and pollen aperture number in mediating HP effects. Additionally, we observed pollen tube growth to determine the conspecific pollen-tube-growth advantage. RESULTS Stigma behavior differed significantly with HP of different species. Pollen load increased, while pollen size decreased, the percentage of permanent closure and stigmatic germination of HP. Stigmatic HP germination increased with increasing aperture number. However, HP effects did not depend on phylogenetic distance. In addition, conspecific pollen had a pollen-tube-growth advantage over HP. CONCLUSIONS Our results provide a good basis for understanding the stigma-pollen recognition process of plant taxa with touch-sensitive stigmas. We concluded that certain flowering traits drive the HP effects on the post-pollination period. To better understand the impact of pollinator sharing and interspecific pollen transfer on plant evolution, we highlight the importance of evaluating more factors that determine HP effects at the community level.

Abstract
The secretory structures of Alismataceae have been described as secretory ducts, laticifer ducts, laticifer canals or schizogenous ducts. However, these terms are not found in the specialized literature, and ontogenetic analyses for the exact classification of these structures are missing. Accordingly, more studies regarding the secretory structures of Alismataceae are necessary to establish homology in the family or in the order. Thus, the aim of this study was to describe the anatomy, ontogeny, distribution in the organs and exudate composition of the secretory structures present in five Alismataceae species in order to determine whether the family has laticifers or secretory ducts. Samples of leaves, flowers and floral apices were processed for anatomical and histochemical analyses by light microscopy. The analysis indicated the presence of anastomosing secretory ducts in all species, occurring in both leaves and flowers. The exudate contains lipids, alkaloids, proteins and polysaccharides, including mucilage. The secretory duct structure, distribution and exudate composition suggest a defense role against herbivory and in wound sealing. The presence of secretory ducts in all species analyzed indicates a probable synapomorphy for the family.

Abstract
Alismataceae, an ancient lineage of monocots, has attracted attention due to its complex evolutionary history, ornamental value, and ecological role. However, the phylogenetic relationships and evolutionary history of the family have not been conclusively resolved. Here, we constructed the first complete genus-level plastid phylogeny of Alismataceae by using 78 genes and updated the historical biogeography based on the phylogenomic tree. Our results divide the Alismataceae into three major clades with robust support values; one clade comprises the former Limnocharitaceae, and the second clade includes the mainly temperate genera Alisma, Baldellia, Damasonium and Luronium, and the monotypic African genus Burnatia as a sister of the temperate genera. The remaining genera are either tropical or have some temperate species in addition to tropical ones, and they constitute the third major clade. Molecular dating and biogeographic analyses suggest that Alismataceae arose in Neotropical, West Palearctic, and Afrotropical regions during the Cretaceous, followed by the split into three main clades due to a combination of vicariance and dispersal events. Unlike earlier studies, we inferred that the mainly temperate clade likely originated from Afrotropical and West Palearctic regions during the Eocene. The most recent common ancestor of the other two clades lived in the Neotropical area during the Late Cretaceous. Long-distance dispersal and vicariance together seem to contribute to the transoceanic distribution of this family.

Abstract
Sagittaria is a genus of ca. 40 species in the aquatic plant family Alismataceae with a nearly global distribution, and a center of diversity in the New World. Two thirds of the known species are native to the Americas, while only a few species are distributed in Africa, Asia and Europe. A previous biogeographic analysis of the genus suggested an African origin for the genus with subsequent dispersal to North America and then to East Asia. Here we expanded the taxon sampling with a focus on the New World taxa and applied species delimitation and biogeographic analyses to revise the knowledge of the phylogeny and evolution of the genus. We obtained largely similar topologies from the chloroplast DNA and nuclear DNA (ITS) data sets. The 74 accessions sampled for our analyses were delimited into 29 species and several cryptic taxa were revealed in widely distributed species. Biogeographic analysis supported basal diversification in South America and subsequent colonization to North America and Asia.

Abstract
Caldesia is a genus in the family Alismataceae mainly found in the tropical and temperate regions of the Northern hemisphere. In China, two species, Caldesia parnassifolia, and Caldesia grandis are recorded as critically endangered in sporadic regions. Available protection of the genetic resource of these threatened species has been impeded due to limited genomic information. Here, we sequence the whole chloroplast (cp) genome of the two Caldesia species using high throughput sequencing technology. The whole cp genomes of C. parnassifolia and C. grandis were 167,647 bp and 168,500 bp, respectively with a typical quadripartite structure. There were 115 unique genes with 81 protein-coding genes, 31 tRNA genes, and four rRNA genes. Both species showed a GC content of 37.1%. A duplication of two tRNA genes and a ~ 6 kb inversion region in the LSC was noted in both species. Mononucleotide simple sequence repeats (SSRs) A/T were most abundant for both Caldesia species. High nucleotide variability was recorded in ycf1 gene and trnK-UUU/rps16 intergenic spacer region. All RNA editing conversions were C-U in 23 and 24 protein-coding genes for C. parnassifolia and C. grandis, respectively. Phylogenetic analysis placed both Caldesia species as sister to Sagittaria lichuanensis. This study will be useful for further evolutionary, systematic researches and conservation of the genus Caldesia.

Abstract
Plant-associated microorganisms are essential for their hosts' survival and performance. Yet, most plant microbiome studies to date have focused on terrestrial species sampled across relatively small spatial scales. Here, we report the results of a global-scale analysis of microbial communities associated with leaf and root surfaces of the marine eelgrass Zostera marina throughout its range in the Northern Hemisphere. By contrasting host microbiomes with those of surrounding seawater and sediment, we uncovered the structure, composition, and variability of microbial communities associated with eelgrass. We also investigated hypotheses about the assembly of the eelgrass microbiome using a metabolic modeling approach. Our results reveal leaf communities displaying high variability and spatial turnover that mirror their adjacent coastal seawater microbiomes. By contrast, roots showed relatively low compositional turnover and were distinct from surrounding sediment communities, a result driven by the enrichment of predicted sulfur-oxidizing bacterial taxa on root surfaces. Predictions from metabolic modeling of enriched taxa were consistent with a habitat-filtering community assembly mechanism whereby similarity in resource use drives taxonomic cooccurrence patterns on belowground, but not aboveground, host tissues. Our work provides evidence for a core eelgrass root microbiome with putative functional roles and highlights potentially disparate processes influencing microbial community assembly on different plant compartments. IMPORTANCE Plants depend critically on their associated microbiome, yet the structure of microbial communities found on marine plants remains poorly understood in comparison to that for terrestrial species. Seagrasses are the only flowering plants that live entirely in marine environments. The return of terrestrial seagrass ancestors to oceans is among the most extreme habitat shifts documented in plants, making them an ideal testbed for the study of microbial symbioses with plants that experience relatively harsh abiotic conditions. In this study, we report the results of a global sampling effort to extensively characterize the structure of microbial communities associated with the widespread seagrass species Zostera marina, or eelgrass, across its geographic range. Our results reveal major differences in the structure and composition of above- versus belowground microbial communities on eelgrass surfaces, as well as their relationships with the environment and host.

Abstract
Reproductive allocation is a key process in the plant life cycle and aquatic plants exhibit great diversity in their reproductive systems. In the present study, we conduct a field investigation of three aquatic macrophytes: Stuckenia pectinata, Myriophyllum spicatum, and Potamogeton perfoliatus. Our results showed that widespread species, including S. pectinata and M. spicatum had greater plasticity in their allocation patterns in the form of increased sexual and asexual reproduction, and greater potential to set seeds and increase fitness in more eutrophic environments. P. perfoliatus also exhibited a capacity to adopt varied sexual reproductive strategies such as setting more offspring for the future, although only in clear conditions with low nutrient levels. Our results establish strategies and mechanisms of some species for tolerating and surviving in varied eutrophic lake conditions.

Abstract
BACKGROUND Aquatic vascular plants are a distinctive group, differing from terrestrial plants in their growth forms and habitats. Among the various aquatic plant life forms, the evolutionary processes of freshwater submerged species are most likely distinct due to their exclusive occurrence in the discrete and patchy aquatic habitats. Using the chloroplast trnL-F region sequence data, we investigated the phylogeographic structure of a submerged macrophyte, Hydrilla verticillata, the single species in the genus Hydrilla, throughout China, in addition to combined sample data from other countries to reveal the colonisation and diversification processes of this species throughout the world. RESULTS We sequenced 681 individuals from 123 sampling locations throughout China and identified a significant phylogeographic structure (NST > GST, p < 0.01), in which four distinct lineages occurred in different areas. A high level of genetic differentiation among populations (global FST = 0.820) was detected. The divergence of Hydrilla was estimated to have occurred in the late Miocene, and the diversification of various clades was dated to the Pleistocene epoch. Biogeographic analyses suggested an East Asian origin of Hydrilla and its subsequent dispersal throughout the world. CONCLUSIONS The presence of all four clades in China indicates that China is most likely the centre of Hydrilla genetic diversity. The worldwide distribution of Hydrilla is due to recent vicariance and dispersal events that occurred in different clades during the Pleistocene. Our findings also provide useful information for the management of invasive Hydrilla in North America.

Abstract
Adaptation to aquatic habitats is a formidable challenge for terrestrial angiosperms that has long intrigued scientists. As part of a suite of work to explore the molecular mechanism of adaptation to aquatic habitats, we here sequenced the transcriptome of the submerged aquatic plant Ranunculus bungei, and two terrestrial relatives R. cantoniensis and R. brotherusii, followed by comparative evolutionary analyses to determine candidate genes for adaption to aquatic habitats. We obtained 126,037, 140,218 and 114,753 contigs for R. bungei, R. cantoniensis and R. brotherusii respectively. Bidirectional Best Hit method and OrthoMCL method identified 11,362 and 8,174 1:1:1 orthologous genes (one ortholog is represented in each of the three species) respectively. Non-synonymous/synonymous (dN/dS) analyses were performed with a maximum likelihood method and an approximate method for the three species-pairs. In total, 14 genes of R. bungei potentially involved in the adaptive transition from terrestrial to aquatic habitats were identified. Some of the homologs to these genes in model plants are involved in vacuole protein formation, regulating 'water transport process' and 'microtubule cytoskeleton organization'. Our study opens the door to understand the molecular mechanism of plant adaptation from terrestrial to aquatic habitats.

Abstract
Haloragaceae are a cosmopolitan plant family with its centre of diversity in Australia. Here, we investigate the historical biogeography of the family and the role of vicariance or dispersal in shaping its current distribution. DNA sequences from ITS, matK and the trnK 5' and trnK 3' introns were obtained for 102 species representing all 8 genera of Haloragaceae for use in Bayesian molecular dating. Molecular dating was conducted using two macrofossils as calibration points for the analyses. Biogeographic history was investigated using a Bayesian dispersal-vicariance analysis and a dispersal-extinction-cladogenesis model. The results suggest that the earliest diversification of the extant Haloragaceae occurred in Australia during the Eocene (37.3-56.3Ma). Early diversification of the family in the Southern Hemisphere is inferred as resulting from vicariance events among Australia, South America and New Zealand. The results also indicate multiple out of Australia dispersal routes, primarily including (1) from Australia to Asia during the Miocene, with subsequent dispersal to Europe and North America; (2) from Australia to New Zealand, then to South America during the Miocene and Pliocene. Most of the inferred dispersal events occurred throughout the Miocene and later, and are biased towards the aquatic Haloragaceae lineages.

Abstract
Alismatidae is a wetland or aquatic herb lineage of monocots with a cosmopolitan distribution. Although considerable progress in systematics and biogeography has been made in the past several decades, geographical origin of this group remains unresolved. In this study, we used statistical dispersal-vicariance analysis implemented in program RASP to investigate the biogeography of Alismatidae. Six areas of endemism were used to describe the distribution: North America, South America, Eurasia, Africa, Southeast Asia and Australia. 18,000 trees retained from Bayesian inference of rbcL served as a framework to reconstruct the ancestral areas. The results suggested that the most recent common ancestor of Alismatidae most probably occurred in Eurasia, followed by a split into two major clades. The clade comprising Hydrocharitaceae, Butomaceae and Alismataceae mainly diversified in Eurasia and Africa. The other clade comprising the remaining families dispersed to southern hemisphere. Australia played an important role in diversification of this clade. Several families were suggested to have occurred in Australia, such as Ruppiaceae, Cymodoceaceae, Posidoniaceae and Zosteraceae.
