Morphological And Molecular Data

The genus Salvia includes an enormous assemblage of nearly 1000 species dispersed around the World. Iran having 19 endemic species out of 61 is regarded as one of the important regions for Salvia diversity in Southwest Asia. Salvia species are herbaceous, rarely biennial or annual, often strongly aromatic. These species are of medicinal, commercial and horticultural value. Due to the importance of these plant species, we performed a combination of morphological and molecular data for this species. For this study, we used 145 randomly collected plants from 30 species in 18 provinces. Amplification of genomic DNA using 10 primers produced 134 bands, of which 129 were polymorphic (97.78%). The obtained high average PIC and MI values revealed high capacity of SCoT primers to detect polymorphic loci among Salvia species. The genetic similarities of 30 collections were estimated from 0.61 to 0.93. According to the SCoT markers analysis, S. tebesana and S. verticillata had the lowest similarity and the species of S. eremophila and S. santolinifolia had the highest similarity. The aims of present study are: 1) can SCoT markers identify Salvia species, 2) what is the genetic structure of these taxa in Iran, and 3) to investigate the species inter-relationship? The present study revealed that SCoT markers can identify the species.

A New Species

Morphological characters support the description of a new species of Passifloraceae from Mayotte Island: Adenia barthelatii M. Pignal, Yockteng, Hearn & Labat. Morphological and molecular data suggest that A. barthelatii belongs to the ‘warty-gland’ subclade of Clade V defined by Hearn elsewhere. Since the warty-gland clade is restricted to the Malagasy region we suggest a Malagasy origin of this Maorian species of Adenia.

ABSTRACT Despite its importance in biogeographical, ecological, and commercial terms, the fish fauna of the northern Brazilian coast is still poorly known, representing the least sampled portion of the Brazilian Exclusive Economic Zone. We collected Tonkin weakfish, Cynoscion similis specimens during extensive surveys of the northern Brazilian coast and concluded that C. similis is common in this region. While the species had not previously been reported for the northern Brazilian state of Pará, it may have been recorded in studies of industrial fisheries, being identified only as Cynoscion sp. or by the common name pescada negra. This reinforces the need for the reliable taxonomical identification of species, to guarantee the collection of accurate data on ecology and fisheries, and ultimately, support the development of effective conservation strategies. Here we provide additional morphological and molecular data to distinguish Cynoscion similis from the closely related Cynoscion jamaicensis, and other congeners.

The aim of this work was to estimate the genetic divergence among accessions of cassava sampled in the Tapajós region in the State of Pará, Brazil, and conserved at the Regional Germplasm Bank of Eastern Amazon, using agronomic descriptors and molecular markers. Twenty-two accessions of cassava were evaluated in the field for two successive years, based on six agronomic descriptors in twelve-months-old plants without a specific experimental design. Accessions were also evaluated with eleven microsatellite loci in an automatic DNA analyser. Descriptive and multivariate statistical analyses were applied. Based on principal components analysis, the character weight of the aerial portion of the plant contributed most to the phenotypical variation. The six traits were used in the analysis of genetic dissimilarity between accessions, and the correlation between matrices generated by morphological and molecular data was estimated. The matrices of genetic dissimilarity were used in the construction of dendrograms using the UPGMA method. We observed a high variation of agronomical descriptors and molecular markers evaluated, which were capable to separate the accessions into distinct groups. A weak positive correlation was detected among the two matrices of genetic distances, which indicates the possibility to explore the genetic diversity using crossings and accessions Amarelinha 36 and Olho roxo 13 are divergent and potentially promising for the generation of heterotic hybrids.

Phaeoclavulina liliputiana is a new endemic species from Tlaxcala, from the conifer and oak forests at an altitude of 2700 m asl, characterized by a very small basidiome size and, subellipsoid and usually more or less lacrymoid spores of 4.3–6.2 × 2.7–3.5 µm, with rounded warted ornamentation. We proposed this new species based on evidence from morphological and molecular data. We provide macro- and microscopic descriptions including illustrations of the basidiocarp, scanning electron micrographs of the basidiospores and also discuss the taxonomic position of this new species. We undertook a molecular analysis using the atp6 and SSU mitochondrial loci and nuclear ribosomal LSU.

Abstract Polyploidization is generally considered a major evolutionary force that can alter the genetic diversity, morphology, physiology and ecology of plants. One striking example is the polyploid Urtica dioica complex, in which diploid taxa are often found in remote and partly relictual geographical ranges, in contrast to tetraploid individuals, which have an unknown evolutionary history and occur in a variety of synanthropic habitats. We used a set of 279 plants, evenly representing the geographical and morphological variation of U. dioica s.l. in Europe and Southwest Asia, and employed multivariate and geometric morphometrics and Hyb-Seq sequencing to estimate the extent of differentiation of diploid taxa and the ubiquitous tetraploid cytotype. Diploid subspecies form more-or-less separate clusters in morphological analyses, but our molecular evaluation did not reveal any structure. Moreover, tetraploids coalesced with diploids in both morphological and molecular analyses. This disparity between morphological and molecular data might be driven by (1) local adaptation of the diploid cytotype that is mirrored in specific phenotypes, (2) only recent genetic diversification of the group and (3) homoploid and heteroploid hybridization events.

Microweiseinae is a quite recently established subfamily within ladybird beetles (Coccinellidae). According to recent analyses of morphological and molecular data, it has been divided into three tribes. Members of the subfamily are distributed mostly in tropical and subtropical regions of the world. Despite several recent taxonomical studies of this group, its diversity and distribution is still not fully understood. Recent field collecting on Madeira Island resulted in the discovery of interesting specimens belonging to a yet unknown taxon, described here as Madeirodula atlantica gen. et sp. nov. Phylogenetic analysis of morphological characters indicate that the new taxon form a distinct branch within the subfamily Microweiseinae, for which we propose a new tribe Madeirodulini trib. nov. Evolutionary trends within the subfamily are discussed, and an updated key to the tribes of Microweiseinae is provided.

Major Progress

Lobelioideae, the largest subfamily within Campanulaceae, includes 33 genera and approximately1200 species. It is characterized by resupinate flowers with zygomorphic corollas and connate anthers and is widely distributed across the world. The systematics of Lobelioideae has been quite challenging over the years, with different scholars postulating varying theories. To outline major progress and highlight the existing systematic problems in Lobelioideae, we conducted a literature review on this subfamily. Additionally, we conducted phylogenetic and biogeographic analyses for Lobelioideae using plastids and internal transcribed spacer regions. We found that former studies have reached agreement on the southern African origin of Lobelioideae, herbaceous habit and Asian origin of giant lobelioids, the convergent evolution of giant rosette lobelioids, and lastly, the multiple cosmopolitan and independent radiation of lobelioids in Africa, Pacific Basin, and the Hawaiian Islands. Also, Apetahia Baill., Sclerotheca A.DC., and Cyanea Gaudich. are paraphyletic, while Lobelia L., Pratia Gaudich., Centropogon C.Presl, Siphocampylus Pohl, and Isotoma Lindl. are polyphyletic. The taxonomy of these genera, especially Lobelia, is particularly quite frustrating. This calls for further reappraisals using both morphological and molecular data.

AbstractRose gall wasps Diplolepis induce structurally distinct galls on wild roses, which provide gallers with food and shelter. These galls are attacked by a wide variety of micro-hymenopterans including another cynipid Periclistus that act as inquilines. Both Diplolepis and Periclistus are difficult to distinguish based on adult morphology, instead the structural appearance of galls is often used to distinguish species. Using the mitochondrial gene COI, we built phylogenies of both Diplolepis and Periclistus, while also estimating the ancestral host use of the inducers. Our phylogeny recovered the monophyly of Diplolepis, which have likely diverged from single-or multi-chambered leaf gallers to other plant organs. Periclistus exhibits a divide between the Palearctic and Nearctic clades, and ranges from specialists to generalists in terms of host specificity. The molecular results have largely supported the validity of species described in the literature, with notable exceptions in four species groups. While it is premature to enact any taxonomic changes without additional molecular markers, this incongruence between morphological and molecular data indicates these groups need taxonomic revision and gall morphology alone may be inadequate to delimit species.

This is the second part of a revision and re-classification of the demosponge family Sollasellidae, and an example of a successful use of combined morphological and molecular data. Sollasella had been a poorly known, long forgotten taxon, placed incertae sedis in the order Hadromerida in the last major revision of the demosponges. It has recently been suggested to belong to Raspailiidae in the order Poecilosclerida due to striking morphological similarities. The present analysis verified this re-classification using molecular markers. Comparing 28S rDNA fragments of Sollasella cervicornis, a newly described species S. moretonensis and a representative set of raspailiid and hadromerid samples. In our analyses Sollasella clearly clusters inside the Raspailiidae clade, and distantly from hadromerid taxa. Supporting morphological hypothesis of Van Soest et al. (2006), that Sollasella is a raspailiid sponge.
