Abstract Background Sacred lotus is a basal eudicot with agricultural, medicinal, cultural and religious importance. It was domesticated in Asia about 7,000 years ago, cultivated for its rhizomes seeds as food crop. particularly noted 1,300-year seed longevity exceptional water repellency, known the effect. The latter property due to nanoscopic closely packed protuberances of self-cleaning leaf surface, which have been adapted manufacture industrial paint, Lotusan. Results genome China...
Previous mapping studies have revealed that the frequency and large size of inverted repeat junction shifts in Apiaceae plastomes are unusual among angiosperms.To further examine plastome structural organization evolution Apiales (Apiaceae + Araliaceae), we determined complete plastid genome sequences five taxa, namely Anthriscus cerefolium (154,719 base pairs), Crithmum maritimum (158,355 Hydrocotyle verticillata (153,207 Petroselinum crispum (152,890 Tiedemannia filiformis subsp.greenmanii...
Angiosperms are the cornerstone of most terrestrial ecosystems and human livelihoods
Phylogenetic relationships among 40 New World and Old members of Apiaceae subfamily Apioideae, representing seven the eight tribes ten subtribes commonly recognized in subfamily, were inferred from nucleotide sequence variation internal transcribed spacer (ITS) regions 18‐26S nuclear ribosomal DNA. Although sequences are alignable, with only 11% sites excluded analyses because alignment ambiguity, divergence values pairwise comparisons unambiguous positions all taxa high ranged 0.5 to 33.2%...
The higher level relationships within Apiaceae (Umbelliferae) subfamily Apioideae are controversial, with no widely acceptable modern classification available. Comparative sequencing of the intron in chloroplast ribosomal protein gene rpl16 was carried out order to examine evolutionary among 119 species (99 genera) and 28 from subfamilies Saniculoideae Hydrocotyloideae, putatively allied families Araliaceae Pittosporaceae. Phylogenetic analyses these sequences alone, or conjunction plastid...
Evolutionary relationships among representatives of Apiaceae (Umbelliferae) subfamily Apioideae have been inferred from phylogenetic analyses nuclear ribosomal DNA internal transcribed spacer (ITS 1 and ITS 2) plastid rpoC1 intron sequences. High levels nucleotide sequence variation preclude the use region for examining across subfamilial boundaries in Apiaceae, whereas is more suitably conserved family-wide study but too closely related taxa. In total, 126 sequences 100 (all three...
Phylogenetic analyses of chloroplast gene (rbcL, matK), intron (rpl16, rps16, rpoC1) and nuclear ribosomal DNA internal transcribed spacer (ITS) sequences restriction sites, with supplementary data from variation in size the genome inverted repeat, have been used to elucidate major clades within Apiaceae (Umbelliferae) subfamily Apioideae Drude. This paper summarizes results previously published molecular cladistic presents a provisional classification based on taxonomic congruence among...
The evolutionary relationships among members of Apiaceae (Umbelliferae) tribe Scandiceae and representatives all major lineages Apioideae (including putatively allied Caucalideae) identified in earlier molecular studies were inferred from nucleotide sequence variation the internal transcribed spacer regions (ITS1 ITS2) nuclear ribosomal DNA. In all, 134 accessions representing 18 genera commonly treated analyzed. Phylogenies estimated using maximum parsimony distance methods generally...

Comparative sequencing of the two internal transcribed spacer regions nuclear ribosomal DNA was carried out to examine evolutionary relationships among representatives Old World Apiaceae (Umbelliferae) subfamily Apioideae. Emphasis placed on delimiting groups within previously designated apioid superclade and clarifying peucedanoid genera Angelica, Ferula, Heracleum, Peucedanum. These data, those obtained from chloroplast rps16 intron for a subset taxa, also enabled hypotheses phylogenetic...
Abstract The phylogenetic relationships and chromosomal evolution of the diverse tropical genus Passiflora (Passifloraceae) are explored using data from two chloroplast markers: rpoC1 intron trnL/trnT spacer region. A survey presence or absence in 136 species representing 17 Killip's (1938) 22 subgenera four other genera Passifloraceae revealed losses 46 taxa. minimum were confirmed by a parametric bootstrap approach on sequence non-coding region for 61 results analyses support reduction to...
It has been suggested that southern Africa is the origin of predominantly herbaceous Apiaceae subfamily Apioideae and woody habit plesiomorphic. We expand previous molecular phylogenetic analyses family by considering all but three approximately 38 genera native to Africa, including whose members, save one, have a habit. Representatives five other are included because they may be closely related these African taxa. Chloroplast DNA rps16 intron and/or nuclear rDNA ITS sequences for 154...
Abstract Phylogenetic analyses of the cpDNA trnQ–trnK5′ exon region for 27 genera and 42 species Saniculoideae early diverging lineages Apioideae were carried out to assess or confirm tribal placements following anomalous genera: Annesorhiza, Astydamia, Chamarea, Choritaenia, Ezosciadium, Itasina, Lichtensteinia, Marlothiella, Molopospermum Phlyctidocarpa . To accommodate these unique members Apiaceae reflect their relationships, a new classification system has become necessary. Many (herein...
Abstract Aim To analyse spatial and temporal patterns of dispersal events in the euapioids (Apiaceae subfamily Apioideae). Location Worldwide, with an emphasis on Northern Hemisphere. Methods A phylogeny was inferred from 1194 nuclear ribosomal DNA internal transcribed spacer (nr ITS ) sequences using Bayesian methods. The reconstruction ancestral areas performed simultaneously phylogenetic inference a Markov discrete phylogeographical model stochastic search variable selection ( BSSVS )....
Abstract Apiaceae (Umbelliferae) is a large angiosperm family that includes many medicinally important species. The ability to identify these species and their adulterants important, yet difficult do so because of subtle fruit morphological differences often lack diagnostic features in preserved specimens. Moreover, dried roots are the official medical organs, making visual identification almost impossible. DNA barcoding has been proposed as powerful taxonomic tool for identification....
Abstract Chloroplast DNA (cpDNA) restriction site maps for 113 species of Apiaceae (Umbelliferae) and the allied families Araliaceae Pittosporaceae were constructed two enzymes examined variation in position JLB, junction between large single copy inverted repeat regions that is typically contained within ribosomal protein S10 operon. With exception one clade subfamily Apioideae, all possess a JLB indistinguishable from found vast majority angiosperms. Within this clade, however, at least...
Previous studies have shown that in several angiosperms and the liverwort Marchantia chloroplast gene rpl2, encoding ribosomal protein L2, is interrupted by an intron, but spinach (Spinacia oleracea, Caryophyllales) this intron has been lost. We determined distribution of rpl2 for 390 species representing 116 angiosperm families. Filter hybridizations reveal absent from genomes all examined families Caryophyllales, suggesting was lost common ancestor order. Sequencing five genera...
Phylogenetic relationships among 25 representatives of the Caryophyllales and three outgroup taxa from Polygonaceae Plumbaginaceae were assessed using structural variation in chloroplast genome restriction site highly conserved inverted repeat region genome. In addition to previously reported loss rpl2 intron common ancestor Caryophyllales, observed mutations include: 1) rpll6 Limonium (Plumbaginaceae); 2) large, phy- logenetically informative deletions within gene ORF2280, 3) parallel, 6-kb...
