Ebook The families and genera of vascular plants - Volume XIII: Flowering plants, monocots (Poaceae)
Ebook "The families and genera of vascular plants - Volume XIII: Flowering plants, monocots (Poaceae)" is the outcome of a modern phylogenetic analysis of the grass family based on multiple sources of data, in particular molecular systematic studies resulting from a concerted effort by researchers worldwide, including the author. In the classification given here grasses are subdivided into 12 subfamilies with 29 tribes and over 700 genera. The keys and descriptions for the taxa above the rank of genus are hierarchical, i.e.

Ebook "Dormancy and resistance in harsh environments" studies on organisms, ranging from aquatic cyanobacteria that produce akinetes to hibernating mammals, are presented, and reveal common but also divergent physiological and molecular pathways for surviving in a dormant form or for tolerating harsh environments.

The intraspecific divergences are slightly different between species, from 3% to 5%. The AGBD analysis and phylogenetic trees also support 14 morphological species. It is also suggested to have more COI sequences of more species for better barcode reference library and better molecular species identification.

Pomacea canaliculata is an important invasive species worldwide. However, little is known about the molecular mechanisms behind species displacement, adaptational abilities, and pesticide resistance, partly because of the lack of genomic information that is available for this species.

According to the current taxonomic delimitation, the Mediterranean genus Iberis comprises about 30 species. Among them, the taxonomy and species delimitation of Iberis simplex and its morphologically close relatives (I. attica, I. carica, I. gypsicola, I. halophila, and I. spruneri), described here as the I. simplex species complex, are controversial and several different names are used for the members of this complex.

Drip loss is a key aspect of meat quality. Transcriptome profiles of muscle with divergent drip loss would offer important insight into the genetic factors responsible for the trait. Our study revealed some GO terms, pathways and potential candidate genes affecting drip loss. It provides crucial information to understand the molecular mechanism of drip loss, and would be of help for improving meat quality of pigs.

Wheat leaf rust is an important disease worldwide. Understanding the pathogenic molecular mechanism of Puccinia triticina Eriks. (Pt) and the inconstant toxic region is critical for managing the disease. The present study aimed to analyze the pathogenic divergence between Pt isolates.

The use of a highly divergent field distribution (i.e. corona discharge or micro discharge) is essential in order to analyse different breakdown stages. In our work, we have measured the emission spectra and specially, the pressure broadening and shift of atomic lines and molecular bands.

Mouse models have allowed for the direct interrogation of genetic effects on molecular, physiological, and behavioral brain phenotypes. However, it is unknown to what extent neurological or psychiatric traits may be human- or primate-specific and therefore which components can be faithfully recapitulated in mouse models.

Hemispheric asymmetry in neuronal processes is a fundamental feature of the human brain and drives symptom lateralization in Parkinson’s disease (PD), but its molecular determinants are unknown. Here, we identify divergent epigenetic patterns involved in hemispheric asymmetry by profiling DNA methylation in isolated prefrontal cortex neurons from control and PD brain hemispheres.

Previous studies on the distribution of the Ahaetulla snake across Indonesia only focused on morphological characters without any molecular data. This study was aimed at analyzing phylogenetic relationships among the genus Ahaetulla in Indonesia based on partial mitochondrial DNA sequences of 16 specimens collected from the Sundaland and Lesser Sunda regions. The 12S-rDNA gene was PCR-amplified and sequenced to analyze phylogenetic relationships and to estimate the divergence time between the 2 Ahaetulla populations of the Sundaland and Lesser Sunda regions.

DNA methylation is one of the major epigenetic modifications influencing the regulation of gene expression. The opium poppy is an important medicinal plant. Its latex contains opium, which is a rich source of pharmaceutical benzyisoquinoline alkaloids (BIA). Here, the methylation-sensitive amplification polymorphism (MSAP) profiling technique using 21 MSAP molecular markers was applied in order to compare levels of DNA methylation between 6 opium poppy varieties. MSAP profiling reflected the different methylation statuses among opium poppy varieties having divergent BIA content.

Rapid evolution is a hallmark of reproductive genetic systems and arises through the combined processes of sequence divergence, gene gain and loss, and changes in gene and protein expression. While studies aiming to disentangle the molecular ramifications of these processes are progressing, we still know little about the genetic basis of evolutionary transitions in reproductive systems.

Skeletonema species are prominent primary producers, some of which can also cause massive harmful algal blooms (HABs) in coastal waters under specific environmental conditions. Nevertheless, genomic information of Skeletonema species is currently limited, hindering advanced research on their role as primary producers and as HAB species. Mitochondrial genome (mtDNA) has been extensively used as “super barcode” in the phylogenetic analyses and comparative genomic analyses. However, of the 21 accepted Skeletonema species, full-length mtDNAs are currently available only for a single species, S.

The outcome of cervical artificial insemination (AI) with frozen-thawed semen in sheep is limited by the inability of sperm to traverse the cervix of some ewe breeds. Previous research has demonstrated that cervical sperm transport is dependent on ewe breed, as sperm can traverse the cervix in greater numbers in some higher fertility ewe breeds. However, the molecular mechanisms underlying ewe breed differences in sperm transport through the cervix remain unknown.

In avian species, liver is the main site of de novo lipogenesis, and hepatic lipid metabolism relates closely to adipose fat deposition. Using our fat and lean chicken lines of striking differences in abdominal fat content, post-hatch lipid metabolism in both liver and adipose tissues has been studied extensively. However, whether molecular discrepancy for hepatic lipid metabolism exists in chicken embryos remains obscure.

The marine dinoflagellate, Symbiodinium, is a well-known photosynthetic partner for coral and other diverse, non-photosynthetic hosts in subtropical and tropical shallows, where it comprises an essential component of marine ecosystems. Using molecular phylogenetics, the genus Symbiodinium has been classified into nine major clades, A-I, and one of the reported differences among phenotypes is their capacity to synthesize mycosporine-like amino acids (MAAs), which absorb UV radiation.

Chrysanthemum indicum L., an important ancestral species of the flowering plant chrysanthemum, can be used as medicine and for functional food development. Due to the lack of hereditary information for this species and the difficulty of germplasm identification, we herein provide new genetic insight from the perspective of intraspecific transcriptome comparison and present single sequence repeat (SSR) molecular marker recognition technology.

The genetics underlying body mass and growth are key to understanding a wide range of topics in biology, both evolutionary and developmental. Body mass and growth traits are affected by many genetic variants of small effect. This complicates genetic mapping of growth and body mass. Experimental intercrosses between individuals from divergent populations allows us to map naturally occurring genetic variants for selected traits, such as body mass by linkage mapping.
