Only a few mitochondrial genomes have been characterised in subfamily Papilionoideae of Leguminosae. Here, we report the complete mitochondrial genome of Castanospermum australe A.Cunn. & C.Fraser, an important medicinal and ornamental species in the Aldinoid clade of Papilionoideae. By mapping paired-end reads, seven hypothetical subgenomic conformations were rejected and two hypothetical complete isometric mitochondrial genome conformations that differed by a 64-kb inversion were strongly supported. Quantitative assessment of repeat-spanning read pairs showed a major conformation (MC1) and a minor conformation (MC2). The complete mitochondrial genome of C. australe was, thus, generated as 542079bp in length, with a high depth of coverage (~389.7×). Annotation of this mitochondrial genome yielded 58 genes encoding 37 proteins, 18 tRNAs and three rRNAs, as well as 17 introns and three medium-sized repeats (133, 119 and 114bp). Comparison of 10 mitochondrial genomes from Papilionoideae demonstrated significant variation in genome size, structure, gene content and RNA editing sites. In addition, mitochondrial genes were shown to be potentially useful in resolving the deep relationships of Papilionoideae.\u0000","PeriodicalId":55416,"journal":{"name":"Australian Systematic Botany","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2019-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1071/sb19014","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47129334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The past 6 years in particular have seen revolutionary advances in legume science because of the use of high-throughput sequencing, including the development of numerous types of markers and data useful for evolutionary studies above and below the species level that have enabled resolution of relationships that were previously unattainable. Such resolution, in turn, affords opportunities for hypothesis testing and inference to improve our understanding of legume biodiversity and the patterns and processes that have created one of the most diverse plant families on earth. In addition, the genomics era has seen significant advances in our understanding of the ecology of legumes, including their role as nitrogen fixers in global ecosystems. The accumulation of genetic and genomic data in the form of sequenced genomes and gene-expression profiles made possible through NGS platforms has also vastly affected plant-breeding and conservation efforts. Here, we summarise the knowledge gains enabled by NGS methods in legume biology from the perspectives of evolution, ecology, and development of genetic and genomic resources.","PeriodicalId":55416,"journal":{"name":"Australian Systematic Botany","volume":"32 1","pages":"459 - 483"},"PeriodicalIF":1.6,"publicationDate":"2019-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1071/SB19019","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42452797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hughes","doi":"10.1071/SBV32N6_TB","DOIUrl":"https://doi.org/10.1071/SBV32N6_TB","url":null,"abstract":"The young Gwilym Lewis first joined the Royal Botanic Gardens, Kew, as part of the horticultural staff in 1974. There, his enthusiasm for botany was quickly noticed and he was soon recruited and, subsequently, promoted as part of the team of scientists in the herbarium, later going on to become a senior scientist in integrated monography at Kew. This drive, energy and dedication to botany, which were noted at the age of 22, have never left him. Gwilym has been a key contributor to research at Kew Gardens for nearly 45 years. These four decades have seen monumental changes in legume taxonomy, systematics and evolution, and Gwilym has been an important instigator and contributor to this movement both scientifically and as head of the legume section atKew, and indeed inmanyways, as leader of the legume systematics international research community as a whole in recent years. In the four decades sinceGwilymstarted his career, our vision of legume relationships has profoundly changed. In the early 1980s, the main legume lineages were thought to have evolved from broad common ancestors, exemplified by simple-flowered extratropical woody Caesalpinioideae (Polhill et al. 1981), and were usually portrayed as explicit ancestor-descendant relationships among informal groups of genera. Later in the 1980s, cladistics began to be adopted by legume researchers, the first phylogenetic analyses were presented in Advances in Legume Systematics (ALS) Part 3 (e.g. Crisp and Weston 1987; Lavin 1987; Zandee and Geesink 1987), and Jeff Doyle (1987) described the new molecular-biology tools and data and their tremendous potential for resolving evolutionary relationships. These approaches were fully embraced by the legume systematics community, and, in 1995 (ALS 7), 16 new phylogeneticstudiesacross thefamily,mostusingmoleculardata, were published. In the 1990s, the plastid rbcL gene was being sequenced to look at higher-level legume relationships (Doyle et al. 1997), in 2001, the first full legume plastomes were sequenced, and, in 2008, the full nuclear genome of Lotus japonicus appeared. By the mid-2000s, the phylogenetic framework and time frame of higher-level legume relationships were broadly established (Wojciechowski et al. 2004; Lavin et al. 2005; Bruneau et al. 2008), and, in 2019, we have now amassed DNA-sequence data for more than 5500 legume species, including nuclear genomes (~25 species) and several hundred plastid genomes (e.g. Egan and Vatanparast 2019), as well as produced a much more comprehensively sampled phylogeny of the family as a whole (Legume Phylogeny Working Group 2017).

This new synthesis, the first since Mckey (1989)’s seminal paper, increases the number of genera with EFNs to 153 (20% of legumes), distributed across subfamilies Cercidoideae (1), Detarioideae (19), Caesalpinioideae (87) and Papilionoideae (46). EFNs occur at nine locations, and are most prevalent on vegetative plant parts, especially leaves (74%) and inflorescence axes (26%). Four main categories (with eight subcategories) are recognised and include the following: formless, trichomatic (exposed, hollow), parenchymatic (embedded, pit, flat, elevated) and abscission zone EFNs (non-differentiated, swollen scars). Phylogenetic reconstruction of EFNs suggests independent evolutionary trajectories of different EFN types, with elevated EFNs restricted almost exclusively to Caesalpinioideae (where they underwent spectacular morphological disparification), flat EFNs in Detarioideae, swollen scar EFNs in Papilionoideae, and Cercidoideae is the only subfamily bearing intrastipular EFNs.

The taxon has several similarities with Phyllocladus, together with characters that are absent in extant Phyllocladus species but are otherwise typical of the enclosing scale-leaved clade. Consequently, Huncocladus is interpreted as a relative of Phyllocladus, possibly belonging to its stem group. This view is supported by a phylogenetic analysis of Podocarpaceae, which recovers Huncocladus as sister to Phyllocladus within the here-termed phyllocladoid clade (Phyllocladus + Huncocladus). Huncocladus laubenfelsii is the first macrofossil record of the phyllocladoid lineage in South America or anywhere in the western hemisphere, vastly extending its historical range and constituting an additional lineage shared between Eocene Patagonia and extant and extinct Australasian and South-east Asian rainforests. The disappearance of phyllocladoids from South America adds to the general extinction pattern described previously for southern hemisphere Podocarpaceae, associated with the family’s low drought tolerance in the face of climate change (i.e. aridification). Huncocladus is the oldest record of the phyllocladoids, and it represents a new reference point for temporal calibration and biogeographic inference for the evolution of conifers and Australasian rainforests.\u0000","PeriodicalId":55416,"journal":{"name":"Australian Systematic Botany","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2019-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1071/SB18043","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44385733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
