Data from: Comparative analysis of DNA repeats and identification of novel Fesreba centromeric element in fescues and ryagrasses
<p>Background<br> Cultivated grasses are an important source of food for domestic animals worldwide. Better knowledge of their genomes can speed up the development of new cultivars with better quality and resistance to biotic and abiotic stresses. The most widely grown grasses are tetraploid ryegrass species ( Lolium spp.) and diploid and hexaploid fescue species (Festuca spp.). In this work, we characterized repetitive DNA sequences and their contribution to genome size in five fescue and two ryegrass species, as well as one fescue and two ryegrass cultivars.</p> <p>Results<br> Partial genome sequences produced by Illumina technology were used for genome-wide comparative analyses using RepeatExplorer pipeline. Retrotransposons were found to be the most abundant repeat types in all seven grass species. Athila element of Ty3/gypsy family showed the most striking differences in copy number between fescues and ryegrasses. The sequence data enabled the assembly of an LTR element Fesreba, which is highly enriched in centromeric and (peri)centromeric regions in all species. A combination of FISH with a probe specific to Fesreba element and immunostaining with CENH3 antibody showed their colocalization and indicated a possible role of Fesreba in centromere function.</p> <p>Conclusions<br> Comparative repeatome analysis in a set of fescues and ryegrasses provided new insights into their genome organization and divergence, including the assembly of LTR element Fesreba. A new LTR element Fesreba was identified and found abundant in centromeric regions of the fescues and ryegrasses. It may have a role in the function of their centromeres.</p>
Combined-evidence analyses of ultraconserved elements and morphological data: an empirical example in iguanian lizards
<p>Genomic datasets generated by next-generation sequencing are increasingly prevalent in phylogenetics, but morphological data are required to phylogenetically place fossils, corroborate molecular hypotheses, and date phylogenies. Combined-evidence analyses provide an integrative assessment of tree topology. However, no attempt has been made to simultaneously analyze next-generation genomic datasets and morphological data, and the future of morphology in the context of genomic data is uncertain. I conducted combined-evidence analyses that include genomic and morphological datasets, specifically, with ultraconserved elements and two morphological matrices. In unweighted maximum likelihood and Bayesian combined-evidence analyses, morphological signal was dwarfed by the ultraconserved elements, and some node support values were reduced relative to ultraconserved element-only analyses. Increasing the weight of morphological characters allowed those data to influence the tree, but weighting subjectivity should be considered in future analyses. More attempts should be made to simultaneously analyze genomic and morphological datasets.</p>
Data from: Biological stoichiometry of oleaginous microalgal lipid synthesis: The role of N:P supply ratios and growth rate on microalgal elemental and biochemical composition
<p>Biological Stoichiometry is an ecological framework connecting the balance of elements to the functioning of organisms. Here, we applied this framework to study the relationships between carbon:nitrogen:phosphorus (C:N:P) ratios and synthesis of industrial high value biochemicals in the highly oleaginous alga <em>Tetradesmus bernardii.</em> We expected an increase in protein content with increasing cellular N content and decreasing C:N stoichiometry, and an increase in lipid content with increasing C:N and C:P stoichiometry. We tested these hypotheses by exposing <em>T. bernardii</em> to N and P limitation at a range of N:P supply ratios in chemostats set at low and high dilution rates. Following expectations, the cellular protein content increased with the N content, and decreased with cellular C:N ratios across all treatments. Carbohydrates and lipids largely followed the relative availability of C and increased under both N and P limitation, with higher C:N and C:P ratios. Specifically, lipid content increased by 100–125% upon N and P limitation, with a shift towards more neutral lipids at the cost of glycolipids and phospholipids. Generally, we observed a re-allocation of cellular C from protein to carbohydrates upon modest N limitation, and towards lipids under P and severe N limitation. Our results demonstrate stoichiometrically predictable patterns of industrially valuable compounds in an oleaginous microalga.</p>
