Dynamics and impact of mobile genetic elements in the moss physcomitrium patens
/
Vendrell Mir, Pol ;
Casacuberta i Suñer, Josep M., 1962-, dir.
Els elements genètics mòbils son material genètic amb la capacitat de moure's en el genoma o, en alguns casos, entre diferents organismes o cèl·lules. Podem distingir dues classes d'elements genètics mòbils, els virus, que tenen la capacitat de transferir el seu material gènic entre organismes, i els transposons, que es mouen i es repliquen dins el genoma de l'hoste. [...]

Mobile genetic elements are genetic material with the ability to move within the genome or, in some cases, between different organisms or cells. Two classes of mobile genetic elements can be distinguished, viruses, which have the ability to transfer their genetic material between organisms, and transposons, which move and replicate within the genome of the host organism.

Key message: Transposon insertion polymorphisms can improve prediction of complex agronomic traits in rice compared to using SNPs only, especially when accessions to be predicted are less related to the training set. [...]

CRISPR-Cas9 has proven to be highly valuable for genome editing in plants, including the model plant Physcomitrium patens. However, the fact that most of the editing events produced using the native Cas9 nuclease correspond to small insertions and deletions is a limitation. [...]

Transposable elements (TEs) are a rich source of genetic variability. Among TEs, miniature inverted-repeat TEs (MITEs) are of particular interest as they are present in high copy numbers in plant genomes and are closely associated with genes. [...]

Similarly to other plant genomes of similar size, more than half of the genome of P. patens is covered by Transposable Elements (TEs). However, the composition and distribution of P. patens TEs is quite peculiar, with Long Terminal Repeat (LTR)-retrotransposons, which form patches of TE-rich regions interleaved with gene-rich regions, accounting for the vast majority of the TE space.

Genomics of evolutionary novelty in hybrids and polyploids

Wendel, Jonathan F. (Iowa State University. Department of Ecology, Evolution, and Organismal Biology (USA))
It has long been recognized that hybridization and polyploidy are prominent processes in plant evolution. Although classically recognized as significant in speciation and adaptation, recognition of the importance of interspecific gene flow has dramatically increased during the genomics era, concomitant with an unending flood of empirical examples, with or without genome doubling.

The published melon (Cucumis melo L. ) reference genome assembly (v3. 6. 1) has still 41. 6 Mb (Megabases) of sequences unassigned to pseudo-chromosomes and about 57 Mb of gaps. Although different approaches have been undertaken to improve the melon genome assembly in recent years, the high percentage of repeats (~40%) and limitations due to read length have made it difficult to resolve gaps and scaffold's misassignments to pseudomolecules, especially in the heterochromatic regions.
