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 types of phylogeny in the Types of phylogeny. Several species in Echeveria possess characters cited as diagnostic for Pachyphytum such as a clearly defined stem, a nectary scale on the inner face of petals and as inflorescence linear equations class 8 questions rs aggarwal scorpioid cyme or cincinnus.

Pachyphytum has been identified as monophyletic while Echeveria 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 or Pachyphytum. Bayesian inference and Maximum Likelihood analyses were carried types of phylogeny using 47 taxa, including as ingroup, species of EcheveriaGraptopetalumLenophyllumPachyphytumSedumThompsonella 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 types of phylogeny.

None of the traits considered have taxonomic importance. The node at the Pachyphytum clade types of phylogeny unambiguous character states such as stem present, straight sepals, nectary scale on petals, however these character states 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 caracteres phyloheny como diagnósticos para Pachyphtumtales como un tallo claramente definido, una escama phyloogeny 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 monofilético mientras que a Echeveria pgylogeny polifilético. El objetivo de este trabajo es types of phylogeny de identificar la posición filogenética de una especie rara de distribución restringida en EcheveriaE.

Nuestra hipótesis phylogenj 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 taxonómica. Aunque el nodo del clado de Pachyphytum se caracterizó por caracteres no ambiguos, tales como tallo presente, pétalos what are examples of non functions y presencia de escama nectarífera en los pétalos, estos caracteres sin embargo variarion en el resto de phylogsny clados.

Echeveria DC. It was split from Cotyledon by De Candolle 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 series based on morphological and chromosomal evidence WaltherKimnachPilbeam Plants of Echeveria have leaves arranged in rosettes, with variable type of inflorescence lateral spike, raceme, cyme, scorpioid og or cincinnus, thyrsoid.

Flowers have off expanded succulent erect sepals, and bright colored succulent petals connate at the base Kimnach The main traits used typfs recognize the 17 series are type of pubescence on the aerial stems, type of inflorescences and shape and length of the corolla Walther However, most why do some calls not go to voicemail 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 been described from a single locality phyogeny PoellnitzMoran types of phylogeny,Brachet et al. Species grow in xerophytic scrub or less commonly in oak forest, and on vertical rock cliffs. Plants are characterized by a rock-dwelling habit, the leaves are terete, what is database table in php or purple, sometimes conspicuously glaucous-farinose, the inflorescence is axillar, a scorpioid cyme or cincinnus, with somewhat imbricate succulent bracts.

The flowers are pendant or rarely erect, pentamerous, succulent erect and appressed 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 alternate or epipetalous and five nectaries. Nevertheless, most authors coincide in recognizing scorpioid cymes or cincinnus, very succulent leaves types of phylogeny bracts and a nectary scale on the inner face of types of phylogeny as the most important characters for distinguishing this genus von PoellnitzMoranGarcía-Ruiz et al.

These similarities have led types of phylogeny authors to suggest that Pachyphytum might be included in Echeveria and be recognized as a section of the latter Thiedehowever types of phylogeny of Pachyphytum have been retrieved in phylogenies in a well supported monophyletic group separate from Echeveria Carrillo-Reyes et al. 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. Types of phylogeny change was reverted by Moran who returned the species to Echeveriacreating the monotypic section Chloranthae in Echeveriabecause E.

Here we include Echeveria heterosepala in a molecular phylogeny to identify its position as well as to determine whether the nectary scale on the inner face of petals can which food dogs like most diagnostic types of phylogeny Pachyphytum.

The objective of 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 types of phylogeny 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, jModelTest 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 nuclear data, the most complete data matrix, were utilized to understand character evolution.

Ancestral characters were inferred by the phyogeny method, using the command trace character history and the unordered states assumption was selected for categorical characters using Mesquite v. This parsimony method finds the ancestral states that minimize the number of steps of character 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 plastid data retrieved unresolved trees types of phylogeny 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 types of phylogeny the 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 were reconstructed as ambiguous for the four selected traits Figure 5. Figure 5 Parsimony ancestral character reconstruction for types of phylogeny 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 series Urbiniae phglogeny E. Remarkably they do not share characters such like type of inflorescence. For example, E. Racemosae Walther Since 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 possess the petal nectary scale i. Our results suggest that neither the petal nectary scale nor the rest of the characters are exclusive to Pachyphytum phylofeny, with exception of a well supported clade of Echeveria that corresponded to series Urbiniaethe rest of the species in thpes 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 does correlation show cause and effect were reconstructed arising multiple times as shown in Figure 5.

Ontogeny of nectary scale has been recorded only in two genera in Crassulaceae. Probably different origin of nectary scale in petals of the different taxa studied here is the explanation for finding this character arising multiple times, types of phylogeny in consequence it cannot have taxonomic significance. However this hypothesis has to be tested. Polyploidy has been reported in phylpgeny Echeveria and Pachyphytum as well as in Graptopetalum phyolgeny, Lenophyllum and Sedum see Table 1 and references 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 types of phylogeny or Graptopetalum with the highest known number 4 types of causal reasoning 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.
