Rapid morphological evolution in placental mammals post-dates the origin of the crown group.
(The Royal Society, 2019-03-13)
Resolving the timing and pattern of early placental mammal evolution has been confounded by conflict among divergence date estimates from interpretation of the fossil record and from molecular-clock dating studies. Despite ...
Parental transposable element loads influence their dynamics in young Nicotiana hybrids and allotetraploids.
(Wiley on behalf of New Phytologist Trust, 2019-02)
The genomic shock hypothesis suggests that allopolyploidy is associated with genome changes driven by transposable elements, as a response to imbalances between parental insertion loads. To explore this hypothesis, we ...
