Adaptive Role

Transposable elements (TEs) are agents of genetic variability in phytopathogens as they are a source of adaptive evolution through genome diversification. Although many studies have uncovered information on TEs, the exact mechanism behind TE-induced changes within the genome remains poorly understood. Furthermore, convergent trends towards bigger genomes, emergence of novel genes and gain or loss of genes implicate a TE-regulated genome plasticity of fungal phytopathogens. TEs are able to alter gene expression by revamping the cis-regulatory elements or recruiting epigenetic control. Recent findings show that TEs recruit epigenetic control on the expression of effector genes as part of the coordinated infection strategy. In addition to genome plasticity and diversity, fungal pathogenicity is an area of economic concern. A survey of TE distribution suggests that their proximity to pathogenicity genes TEs may act as sites for emergence of novel pathogenicity factors via nucleotide changes and expansion or reduction of the gene family. Through a systematic survey of literature, we were able to conclude that the role of TEs in fungi is wide: ranging from genome plasticity, pathogenicity to adaptive behavior in evolution. This review also identifies the gaps in knowledge that requires further elucidation for a better understanding of TEs’ contribution to genome architecture and versatility.

Adaptive Role

This study examined associations among adolescent risk preference and political engagement using nationally representative Monitoring the Future data from high school seniors (N=109,574; modal age=18 years) spanning 1976-2014. Greater risk preference was associated with greater past voting, donating to a campaign, writing government officials, boycotting, and protesting. Greater risk preference was associated with higher future intentions to boycott and protest, but lower intentions to donate to or volunteer for a campaign. In general, associations between risk preference and political engagement became stronger with higher levels of political interest. Results highlight the importance of considering the adaptive role of adolescent risk preference and suggest that political engagement may be a constructive outlet for youth who pursue or are comfortable taking risks.
