We present the results of two exploratory parsimony analyses DNA sequences from 475 and 499 species seed plants, respectively, representing all major taxonomic groups.The data are exclusively chloroplast gene rbcL, which codes for large subunit ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO or RuBPCase).We used different state-transformation assumptions resulting in sets cladograms: (i) equal-weighting 499-taxon analysis; (ii) a procedure that differentially weights transversions...
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...
Apiaceae and Araliaceae (Apiales) represent a particularly troublesome example of the difficulty in understanding evolutionary relationships between tropical‐temperate family pairs. Previous studies based on rbc L sequence data provided insights at higher levels, but were unable to resolve fully family‐pair relationship. In this study, from more rapidly evolving gene, mat K , was employed provide greater resolution. Apiales, sequences evolve an average about two times faster than sequences....
Phylogenetic relationships among the genera of Apiaceae are poorly understood, and commonly employed systems classification this family widely regarded as artificial. The understand- ing evolutionary in has been hampered by difficulties interpreting traditional taxonomic characters, especially fruit characters. A cladistic analysis 53 sequences from chloroplast gene matK was used to provide a phylogenetic perspective for patterns Apiaceae. Results mnatK sequence data conflict with...
Phylogenetic analyses of ITS sequence data from 70 species and 40 genera Araliaceae (representing all major lineages within the ''core group'' family) do not support widely used traditional division into three tribes. Tribe Aralieae (characterized by imbricate petals) is found nested a paraphyletic Schefflerieae (whose taxa have valvate petals). There are, however, two large monophyletic groups comprising most araliad genera: ''Aralia-Polyscias-Pseudopanax (which in- cludes Aralia, Meryta,...

These arose this region, probably within past 50–60 yr, provide one best models for study polyploidy plants. The parental both have been well documented, each has apparently formed multiple times. However, a...
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...
The two families of the order Apiales (Apiaceae and Araliaceae) represent a classic example difficulty in understanding evolutionary relationships between tropical‐temperate family pairs. In Apiales, this problem is further compounded by phylogenetic confusion at almost every taxonomic level, including ordinal, interfamilial, infrafamilial, due largely to difficulties trends morphological evolution. Phylogenetic analyses rbc L sequences were employed resolve ordinal familial levels. results...
Relationships within the angiosperm order Apiales have long been difficult to interpret. Traditionally, comprised two families, Apiaceae and Araliaceae. Recent studies, however, suggest three additional lineages should also be recognized in (Pittosporaceae plus tribes segregated from Araliaceae, Mackinlayeae Myodocarpeae), that one taxon (Apiaceae subfamily Hydrocotyloideae) is polyphyletic. Nuclear data support placement of five enigmatic genera (Aralidium, Griselinia, Melanophylla,...
Despite the long history of recognising angiosperm order Apiales as a natural alliance, circumscription and relationships among its constituent groups have been troublesome. Recent studies, however, made great progress in understanding phylo- genetic Apiales. Although much this recent work has based on molecular data, results are congruent with other sources including morphology geography. A unified picture now emerged regarding delimitation Apiales, which includes core group four families...
Each year, an average of 45 tropical cyclones affect coastal areas and potentially impact forests. The proportion the most intense has increased over past four decades is predicted to continue do so. Yet, it remains uncertain how topographical exposure tree characteristics can mediate damage caused by increasing wind speed. Here, we compiled empirical data on 11 occurring 40 years, from 74 forest plots representing regions worldwide, encompassing field for 22,176 trees 815 species. We...
Abstract Astropanax is a monophyletic genus found in the Africa–Madagascar–Seychelles region whose evolutionary and biogeographic history, that of related Araliaceae genera, are poorly known. In this paper, we report presence leaves pollen Ethiopia 21.73 million years ago from Mush Valley locality, which preserves leaf material with cuticles, fruits, seeds, woods, less common biota including insects. was part moist tropical forest community surrounding volcanic crater lake dominated by...
Traditional sources of taxonomic characters in the large and taxonomically complex subfamily Apioideae (Apiaceae) have been confounding no classification system has widely accepted. A restriction site analysis chloroplast genome from 78 representatives related groups provided a data matrix 990 variable (750 which were potentially parsimony‐informative). comparison these to that three recent DNA sequencing studies (based on ITS, rpoCl intron, matK sequences) shows provides 2.6–3.6 times more...
Premise The carrot family (Apiaceae) comprises 466 genera, which include many well‐known crops (e.g., aniseed, caraway, carrots, celery, coriander, cumin, dill, fennel, parsley, and parsnips). Higher‐level phylogenetic relationships among subfamilies, tribes, other major clades of Apiaceae are not fully resolved. This study aims to address this important knowledge gap. Methods Target sequence capture with the universal Angiosperms353 probe set was used examine in 234 genera Apiaceae,...
Phylogenetic relationships involving the angiosperm order Apiales (Apiaceae and Araliaceae) are troublesome at nearly every taxonomic level have eluded several generations of botanists. Because difficulties in interpreting polarizing morphological character states deeper phylogenetic levels, most studies focused on between two families among/within apialean genera. In present study, however, recent contributions from molecular analyses reviewed combined using a ‘supertree’ approach to test...
