The online resource http://www.plantrdnadatabase.com/ stores information on the number, chromosomal locations and structure of 5S 18S-5.8S-26S (35S) ribosomal DNAs (rDNA) in plants. This was exploited to study relationships between rDNA locus distribution, occurrence linked (L-type) separated (S-type) 35S units, chromosome genome size ploidy level. analyses presented summarise current knowledge numbers distribution We analysed 2949 karyotypes, from 1791 species 86 plant families, performed...
Abstract The Catalan Initiative for the Earth BioGenome Project (CBP) is an EBP-affiliated project network aimed at sequencing genome of >40 000 eukaryotic species estimated to live in Catalan-speaking territories (Catalan Linguistic Area, CLA). These represent a biodiversity hotspot. While covering less than 1% Europe, they are home about one fourth all known European species. include high proportion endemisms, many which threatened. This trend likely get worse as effects global...
The new outline of relationships in basal branches the family Compositae Giseke confirms that sister group to tribe Cardueae Cass. are not Mutisieae Cass., but rather a African genera now classified as Tarchonantheae Kostel. This change implies monophyly must be reassessed on molecular basis. Moreover, collections recent years allow us extend our sampling 70 74 tribe. We performed study using one nuclear region (ITS) and two chloroplastic markers (trnL-trnF matK) addition more appropriate...
Studies suggesting that medicinal plants are not chosen at random becoming more common. The goal of this work is to shed light on the role botanical families in ethnobotany, depicting a molecular phylogenetic frame relationships between and uses vascular several Catalan-speaking territories. simple quantitative analyses for ailments categories construction disorders matrix were carried out study. A Bayesian approach was used estimate over- underused flora. Phylogenetically informed identify...
Abstract: Sequences of the internal transcribed spacers (ITS1 and ITS2) nuclear ribosomal DNA were analysed for 44 Artemisia species (46 populations) representing all five classical subgenera geographical range genus, 11 from 10 genera closely related to Artemisia, six outgroup other Anthemideae. The results definitely support monophyly genus in its broadest sense (including some taxa segregated as independent genera, like Oligosporus Seriphidium ). Eight main clades are established this...
• Background and Aims Plant genome size is an important biological characteristic, with relationships to systematics, ecology distribution. Currently, there no information regarding nuclear DNA content for any Carthamus species. In addition improving the knowledge base, this research focuses on interspecific variation its implications infrageneric classification of genus. Genome in process allopolyploid formation also addressed.
Polyploidy is a key factor in the evolution of higher plants and plays an important role variation plant genomes, leading to speciation some cases. During polyploidisation, different balancing processes take place at genomic level that can promote nuclear DNA content. We estimated genome size using flow cytometry 84 populations 67 Artemisia species one population Crossostephium chinense. A total 73 sequences nrDNA ITS 3'-ETS were newly generated analysed, together with previously published...
Considered a biodiversity hotspot, the Canary Islands have been key subjects of numerous evolutionary studies concerning large variety organisms. The genus Cheirolophus (Asteraceae) represents one largest plant radiations in Canarian archipelago. In contrast, only few species occur Mediterranean region, putative ancestral area genus. Here, our main aim was to reconstruct phylogenetic and biogeographic history with special focus on explaining origin radiation.We found significant incongruence...
Two plant genome size databases have been recently updated and/or extended: the Plant DNA C-values database (http://data.kew.org/cvalues), and GSAD, Genome Size in Asteraceae (http://www.asteraceaegenomesize.com). While first provides information on nuclear contents across land plants some algal groups, second is focused one of largest most economically important angiosperm families, Asteraceae. data numerous applications: they can be used comparative studies evolution, or as a tool to...
The discovery of the antimalarial agent artemisinin is considered one most significant success stories ethnopharmacological research in recent times. isolation was inspired by use Artemisia annua traditional Chinese medicine (TCM) and awarded a Nobel Prize 2015. Antimalarial activity has since been demonstrated for range other species, suggesting that genus could provide alternative sources treatments. Given stunning diversity (c. 500 species), prioritisation taxa to be investigated their...
Optical methods, as fluorescence microscopy or hyperspectral imaging, are commonly used for plants visualization and characterization. Another powerful collection of optical techniques is the so-called polarimetry, widely to enhance image contrast in multiple applications. In botanical applications framework, spite some works have already highlighted depolarizing print that plant structures left on input polarized beams, potential polarimetric methods has not been properly exploited. fact,...
Changes in the amount of repetitive DNA (dispersed and tandem repeats) are considered main contributors to genome size variation across plant species absence polyploidy. However, study repeatome dynamism groups showing contrasting genomic features complex evolutionary histories is needed determine whether other processes underlying may have been overlooked. The aim here was elucidate which mechanism best explains evolution Anacyclus (Asteraceae).Using data from Illumina sequencing, we...
Abstract Optical microscopy techniques for plant inspection benefit from the fact that at least one of multiple properties light (intensity, phase, wavelength, polarization) may be modified by vegetal tissues. Paradoxically, polarimetric although being a mature technique in biophotonics, is not so commonly used botany. Importantly, only specific observables, as birefringence or dichroism, have some presence botany studies, and other relevant metrics, those based on depolarization, are...
