TL;DR: An Agrobacterium-mediated transformation system for the model ecological expression system, Nicotiana attenuata, a native tobacco that occupies the post-fire niche in the Great Basin Desert of North America is presented.

TL;DR: It is proposed that both natural and synthetic polyploids are well suited for studying the evolution of adaptive responses, and both allo- and autotetraploidy induce considerable morphological, genetic and genomic changes, many of which are retained by at least one of the naturalpolyploids.

TL;DR: It is concluded that nicotine decreases the palatability of N. sylvestris leaves to the nicotine-resistant M. sexta larvae, and larval consumption and performance were negatively correlated with constitutive nicotine levels.

TL;DR: A suite of induced herbivore resistance traits in three independent lines of the synthetic allopolyploid Nicotianaxmierata and its parent species, N. miersii and N. attenuata, are examined to determine how a complex polygenetic adaptation fares during the early stages of neoallopolyploids formation.

TL;DR: The results obtained show that Arum cyrenaicum and Arum concinnatum emit a strong dung smell and exhibit the distinctive features associated with this pollination syndrome, and principal component analysis (PCA), based on physiologically active components of the flower odours revealed two different clusters, indicating that pollinators can potentially discriminate between the odours of the two species.
