Abstract: Rapid phenotypic changes in traits of adaptive significance are crucial for organisms to thrive in changing environments. How such phenotypic variation is achieved rapidly, despite limited genetic variation in species that experience a genetic bottleneck is unknown.Capsella rubella, an annual and inbreeding forb (Brassicaceae), is a great system for studying this basic question. Its distribution is wider than those of its congeneric species, despite an extreme genetic bottleneck event that severely diminished … Show more

“…repression of the Elongated Uppermost Internode (EUI) gene, which is due to siRNA production from the intronic TEs [88]. In Arabidopsis and Capsella natural strains, insertions of TEs in the intron of flowering repressor gene Flowering Locus C (FLC) downregulate its expression, and induce early-flowering phenotypes [41,59,89]. Consistent with these reports, we found that rice genes with heterochromatic introns tend to show lower expression in the leaf tissue ( Fig 4B).…”

“…Transposable elements, among the most variable components of the genome, can replicate and integrate into positions, which affects the expression levels of adjacent genes, thereby resulting in genetic diversity 44 . For example, the terminal-repeat retrotransposon in miniature (TRIM) elements insertion in the promoter of MS2 allele in the male-sterile ms2 mutant resulted in an anther-specific expression pattern in wheat 45 .…”

“…Numerous comparative and functional studies have shown how TEs can inflate genome size (Bennetzen & Kellog, 1997;Hawkins et al, 2006;Piegu et al, 2006) and produce novel host phenotypes by inserting into genic regions (McClintock, 1956;Bhattacharyya et al, 1990;van't Hof et al, 2016;Niu et al, 2019). Although these examples have added to the sense that TEs play an important role in evolution (Casacuberta & Gonz alez, 2013;Belyayev, 2014), it also has become clear that TEs are immensely diverse, and that what is found in one species does not necessarily hold in others.…”
