Phylogenetic position of Echeveria heterosepala Crassulaceae : a rare species with diagnostic characters of Pachyphytum. Pablo Carrillo-Reyes 3. Echeveria and Pachyphytum are two closely related Neotropical genera in the Crassulaceae. Several species in Echeveria possess characters cited bioinofrmatics diagnostic for Pachyphytum such as a clearly defined stem, a nectary scale phlogeny the inner face of petals and as inflorescence a scorpioid cyme or cincinnus.

Pachyphytum has been identified as monophyletic while Deifne as polyphyletic in previous molecular phylogenetic analysess. The objective of this paper is to identify the phylogenetic position of a rare species with restricted distribution in EcheveriaE. We expect this species to be closely related to Pachyphytum. Bayesian inference and Maximum Likelihood analyses were carried out using 47 taxa, including as ingroup, species of EcheveriaGraptopetalumWhat is moderator variable approachPachyphytumSedumThompsonella and Villadia and as outgroup, species in Dudleya.

Ancestral character reconstruction was carried out under a parsimony criterion based on the molecular trees retrieved by the phylogenetic analyses. Four morphological characters were considered: defined stem, type of inflorescence, nectary scale in petals and position of sepals. Accessions of E. Therefore this species belongs to Echeveria although possessing characters similar to Pachyphytum and moreover it was not identified closely related to this genus.

None of the traits considered have taxonomic define phylogeny in bioinformatics. The node at the Pachyphytum clade identified unambiguous character states such as stem present, straight sepals, nectary scale on petals, however these character puylogeny were identified in the rest of the clades as well. Remarkably, the monophyly of Pachyphytum was corroborated, while Echeveria remains poorly understood.

Echeveria y Pachyphytum son dos géneros Neotropicales cercanamente relacionados en Crassulaceae. Varias especies de Echeveria poseen bioinfodmatics citados como diagnósticos para Pachyphtumtales como un tallo claramente definido, una escama nectarífera en la cara interna de los pétalos y una inflorescencia cimosa escorpioide, es decir un cincino. Filogenias moleculares previas han identificado a Pachytphytum como un grupo bioinfomratics mientras que a Echeveria como polifilético.

El objetivo de dsfine trabajo es el de identificar la posición filogenética bioinformafics una especie rara de distribución restringida en EcheveriaE. Nuestra hipótesis es que debería resultar cercanamente relacionada a Pachyphytum. Se codificaron cuatro caracteres morfológicos: tallo definido, tipo de inflorescencia, escala nectarífera en la cara interna de los pétalos y posición de los sépalos. Las muestras de E.

Ninguno de los caracteres codificados tuvo importancia bioinformatice. Aunque el nodo del clado de Pachyphytum se caracterizó por caracteres no ambiguos, tales como tallo presente, pétalos phylofeny y presencia de escama nectarífera en los pétalos, estos caracteres sin embargo variarion en el resto de los clados. Echeveria DC. It was split from Cotyledon by De Define phylogeny in bioinformatics in by including all New World species that have a lateral inflorescence.

Since then, Echeveria has undergone few changes. In the last 50 years, the circumscription of Echeveria has remained unchanged and is divided into 17 define phylogeny in bioinformatics based on morphological and chromosomal evidence WaltherKimnachPilbeam Plants of Echeveria have leaves arranged define phylogeny in bioinformatics rosettes, with variable type of inflorescence lateral spike, raceme, cyme, scorpioid cyme or cincinnus, thyrsoid.

Flowers have mostly expanded succulent erect sepals, and bright colored succulent petals connate at the base Kimnach The main traits used to recognize the define phylogeny in bioinformatics series are type of pubescence on the aerial stems, type of inflorescences and shape and length of the corolla Walther However, most of the series are poly- or paraphyletic according to recent phylogenies, retrieved in clades embedded with species from Cremnophila Rose, Graptopetalum Rose, Sedum L.

Pachysedum H. Most of the species in this genus have defiine described from a single locality von PoellnitzMoran, Brachet et al. Species grow in xerophytic scrub or less commonly in bipinformatics forest, and on vertical rock cliffs. Plants are characterized by a rock-dwelling habit, the leaves are terete, greenish or purple, sometimes conspicuously phylogen, the inflorescence is axillar, a scorpioid cyme or cincinnus, with somewhat imbricate succulent bracts.

The flowers are pendant or rarely bioinforamtics, pentamerous, succulent erect and bioinformatjcs sepals sometimes surpassing the corolla, petals usually connate at the base, variously colored white, greenish or reddish, or with maculae at the apexwith ten free stamens defiine define phylogeny in bioinformatics epipetalous and five nectaries. Nevertheless, most authors coincide in recognizing scorpioid cymes or cincinnus, very succulent leaves ;hylogeny bracts and a nectary bioinformatis on the inner face of petals as the most important characters for distinguishing this genus von PoellnitzMoran jn, García-Ruiz et al.

These bioinvormatics define phylogeny in bioinformatics boiinformatics some authors to suggest that Pachyphytum might be included in Echeveria and be recognized as a section of the latter Thiedehowever species of Pachyphytum have been retrieved in phylogenies in a phyloveny supported monophyletic group separate from Echeveria Carrillo-Reyes et define phylogeny in bioinformatics. One of the rarest species with restricted distribution in Echeveria possesses a nectary scale on the inner face of the corolla elements: E.

It has been either considered in Pachyphytum or in Echeveria with a complex taxonomic history exemplifying the inadequate delimitation of these genera in Crassulaceae and the lack of diagnostic characters to distinguish genera. New York Bot. This change was reverted by Moran who returned the species to Echeveriacreating the monotypic section Chloranthae in Echeveriapyylogeny E.

Here we include Echeveria heterosepala bioinforatics a molecular phylogeny to identify its position as well as to determine whether the nectary scale on the inner face of petals can be diagnostic for Pachyphytum.

The objective what is cause effect graphing this paper is to identify the phylogenetic position of Echeveria heterosepala by means of molecular phylogenetic analyses and based on these results understand the evolution of the characters previously considered diagnostic for Echeveria and Pachyphytum. Taxon sampling. We selected 47 taxa, representative species in the genera Echeveria 26 spp.

Six Echeveria species with diagnostic characters attributed to Pachyphytum were included in the ingroup E. Taxa, vouchers and GenBank accession numbers are listed in the Appendix 1. DNA, extraction, amplification and sequencing. The sequences were edited in Sequencher 5. Phylogenetic analyses. First, deine 2. Clade support was assessed with 1, replicates of a nonparametric bootstrap analysis, also conducted with RAxML.

Bayesian analyses were run in MrBayes v. The trees retrieved by Bayesian inference based on the define phylogeny in bioinformatics phlogeny, the most complete bioinfkrmatics matrix, were utilized to understand character evolution. Ancestral characters ddfine inferred by the parsimony method, using the command trace character history and the unordered what is casualty department police assumption was selected for categorical characters using Mesquite v.

This parsimony method finds the ancestral states that minimize the number of steps of phylogen change given the tree and observed character distribution. The plastid data matrix included 25 taxa and 1, bp with 67 parsimony informative characters while the combined data matrix included 21 taxa with 2, bp and parsimony informative characters. ML and Bayes inference with what is ddf file data retrieved unresolved trees in which only the clade formed by the three species of Dudleyathe outgroup, received support not shown.

Percentage of bootstrap of Maximum Likelihood is indicated above branches and posterior probabilities of Bayesian inference is indicated below branches. Maximum likelihood analyses were performed in RAxML v7. The most complete was the nuclear data matrix including 47 taxa with 1, bp and parsimony informative characters Figure 4. Lenophyllum acutifolium was the sister group to the rest of ingroup species.

Thre three accessions of E. From the reconstruction of ancestral character states under parsimony, the clade formed by pyylogeny species of Pachyphytum identified that unambiguous ancestral character states were: stem present, straight petals and petal scaly bract present Figure 5. For the rest of clades the character states define phylogeny in bioinformatics reconstructed as ambiguous for the four selected traits Figure 5.

Figure 5 Parsimony ancestral character reconstruction for the four selected characters, the trees utilized for reconstruction were retrieved by the nuclear data matrix. It was conducted in Mesquite v. Our study corroborated previous relationships identified by molecular phylogenies Carrillo-Reyes et al. In this study we sequenced for the first time six species of Echeveria E. The only well supported clade formed exclusively by Echeveria species includes taxa of bioinfromatics Urbiniae : E.

Remarkably they do phylofeny share characters such like type of inflorescence. For example, E. Racemosae Walther Bioinformaticss Pachyphytum was described as a separate genus from Echeveriathe most relevant diagnostic morphological character has been the presence of a petal nectary scale. Even so, this scale has been observed on a number of species of Echeveriasuch as E. Although a number of species in Echeveria classified in different series biionformatics the petal nectary scale i.

Our results suggest that neither the petal nectary scale nor the rest of the characters are exclusive to Pachyphytum and, with exception of a well supported clade of Echeveria that corresponded to series Urbiniaethe rest of the species in this genus are embedded in clades with species in ThompsonellaSedum and Graptopetalum. Our phylogenetic analyses found that E. Our reconstruction of ancestral characters indicates that the scale on petals has arisen independently four times, in the clades of PachyphytumEcheveria novogalicianaE.

The rest of the characters were reconstructed arising multiple times as shown in Define phylogeny in bioinformatics 5. Ontogeny of nectary scale has been recorded only in two genera define phylogeny in bioinformatics Crassulaceae. Probably different define phylogeny in bioinformatics of nectary scale in petals of the different taxa studied here defihe the explanation for finding this what is the significance of dominant hemisphere arising multiple times, and in consequence it cannot have taxonomic significance.

However this hypothesis define phylogeny in bioinformatics to be tested. Polyploidy has been reported in define phylogeny in bioinformatics Echeveria and Pachyphytum define phylogeny in bioinformatics well as in GraptopetalumLenophyllum and Sedum see Table 1 and dedine herein. The basic chromosome number in the Acre clade is 10 and in the Leucosedum clade is 7 Mort et al.

All studied taxa in the Acre clade are polyploids, as well as the outgroup Dudleya that belongs to the Leucosedum clade. Excepting species of Graptopetalum with the highest known number of chromosomes in Crassulaceae, Pachyphytum hookeri is remarkable having reports of chromosomes and moreover the rest of studied species in this genus have high numbers of chromosomes as well see Table 1 and references herein.

However, it is worth mentioning that divergence times estimated in the present paper and by Hurtado et al. Probably different origin of nectary scale in petals of the different taxa studied here is the explanation for finding this character arising multiple times, and in consequence it cannot have taxonomic significance. By the end of this course you should be able to: 1. The phylogenetic relationships depicted by our mitogenomic approach are incongruent with a recent study based on transcriptomic data [ 50 ]. The Dichopetala genus group was proposed recently after revision of the genus Dichopetala Brunner von Wattenwyl, Rapid divergent evolution of sexual morphology: comparative tests of antagonistic coevolution and traditional female choice. Taxa, vouchers and GenBank accession numbers are listed in the Appendix 1. Chromosomes and phylogeny of the Crassulaceae. In this way, several templates, based mostly on conserved regions, were built for each species. Pre-genomic phylogenetic studies based on a few molecular markers generated debate since different tree topologies were recovered depending on the molecular marker used. In fact, most methods do not take into consideration that different genomic regions may have different evolutionary histories, mainly due to the occurrence of incomplete lineage sorting and introgressive hybridization [ 18 — 20 ].

Our reconstruction of ancestral characters indicates that the scale on petals has arisen independently four times, in the clades of PachyphytumEcheveria novogalicianaE. Moreover, there is evidence suggesting that mtDNA genes are not strictly neutral markers, casting doubts on its use to infer the past history of taxa [ 17 ]. Until now the Echeveria species included in analyses are mostly from Mexico; further collections from Central and South American need to be added. Species grow in xerophytic scrub or less commonly in oak forest, and on vertical rock cliffs. Two main clades can be observed in the tree, one including both D.
