Sentences with phrase «gene family expansions»

Although it shows no sign of the whole - genome triplication identified in Solanaceae species such as tomato, the genome includes several species - specific gene family expansions, among them N - methyltransferases (NMTs) involved in caffeine production, defense - related genes, and alkaloid and flavonoid enzymes involved in secondary compound synthesis.

Not exact matches

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.

Armed with the both the king cobra and Burmese python genome the team was able to show that, despite previous hypotheses that venom genes evolve «early» in the lineage leading to snakes, venom gene families do not duplicate early, in fact the study shows that the rapid and extensive expansion of functionally important venom toxin families is restricted to the venomous «advanced» snake lineage.

Candida species that often cause disease usually have expansions in these gene families, so given that C. krusei is rarely pathogenic, this finding makes sense.

Genome comparison revealed that the great expansion of several gene families in the deep - sea mussel may be related to its adaptation to the deep sea.

In P. cynomolgi, we observed an expansion of the STP1 family (51 genes).

Although we have seen that sponges and eumetazoans share many common pathways related to morphogenesis and cell - type specification, there are notable genomic differences, including different microRNA assemblages46, lineage - specific domains and domain architectures, and the differential expansions of gene families.

The most notable expansion was in the protocadherins, a family of genes that regulate neuronal development and short - range interactions between neurons.

The researchers discovered striking differences from other invertebrates, including widespread genomic rearrangements and a dramatic expansion of a family of genes involved in neuronal development that was once thought to be unique to vertebrates.

Instead, the evolution of the octopus genome was likely driven by the expansion of a few specific gene families, widespread genome shuffling and the appearance of novel genes.
