Sentences with phrase «of gene families»

The study sheds light on the mechanisms and adaptive significance of gene family evolution.

Today, science has evolved to the mapping of gene families, and to the systematic determination of the interactions between gene products.

Analysis of mutants in additional members of the gene family revealed that RIP2 and RIP9 are required for efficient editing of many chloroplast C targets, while RIP3 and RIP8 control the editing of many mitochondrial transcripts.

«The exciting thing here is the expansion of a gene family associated with expression in specific neurons,» says Evan Eichler, a geneticist at the University of Washington, Seattle.

C. krusei, they found, has few copies of gene families associated with pathogenesis in C. albicans, including oligopeptide transporters, aspartyl proteases, and phospholipase B genes.

The expansion of gene families related to immune recognition, endocytosis and caspase - mediated apoptosis indicates the mussel's adaptation to the presence of chemoautotrophic endosymbionts in its gills.

Fisher's exact test as implemented in R66 was run to test for enrichment or depletion of numbers of gene families for each molecular function category in the novel versus ancestral gene sets.

One surprise revealed by the genome work was that honeybees seemed to have a dearth of some gene families in select areas: taste, immunity and cell detoxification.

They were able to show that 27 per cent of these gene families appeared in a short evolutionary burst which began about 3.3 billion years ago (Nature, DOI: 10.1038 / nature09649).

Assembly of the Norway spruce genome has shown that LTR retrotransposons in particular are frequently nested within the long introns of some gene families (Nystedt et al. 2013).

Automated and Accurate Estimation of Gene Family Abundance from Shotgun Metagenomes — Stephen Nayfach — PLOS Computational Biology — November 2015

From manual curation to visualization of gene families and networks across Solanaceae plant species

The analysis suggested that a protein produced by a gene called Olig2, which is only expressed in the neural progenitors that create motor neurons, promotes motor neuron formation by interfering with the activity of several members of another gene family — the Hes genes.

«We have also found a number of gene families that seem to be involved in the parasitism of insects by worms and we are excited to continue studying these in future experiments.»

These adaptations include the massive and rapid expansion of gene families that produce venom toxins, providing the snake with a highly toxic protein mixture required to overcome a variety of different prey and also circumvent any resistance to venom that may have developed in such prey.

Most structural and regulatory genes in eukaryotes are members of gene families.

And «as each complete genome unfolds,» says Sean Carroll, an evolution and development researcher at the University of Wisconsin, Madison, «we are getting a bigger and better picture of patterns of gene evolution and of gene families.»

The paper describes the first study that relates the gene egr - 4 — member of a gene family that codifies transcription factors and regulate the activity of other genes — with the process of neurogenesis in planarians.

The researchers thus went on to study the expression of Wnt genes during regeneration, and found that different members of the gene family were active at different locations across the planarian's head - to - tail axis.
