Evolution of proteinase inhibitor defenses in North American allopolyploid species of Nicotiana.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We studied the jasmonate (JA)-elicited trypsin-proteinase inhibitor (TPI) anti-herbivore defense system in North American Nicotiana to understand how complex polygenetic traits evolve after allopolyploidy speciation. N. quadrivalvis (Nq) and N. clevelandii (Nc) are allotetraploid descendant species of the ancestors of the diploid species N. attenuata (Na) and N. obtusifolia (No). From cDNA, intron and promoter sequence analyses, and Southern blotting, we deduced that only the maternally derived No TPI genes were retained in the tetraploid genomes (Nq, Nc), whereas the sequences of the paternal Na ancestor were deleted. The number of TPI repeats in different Nicotiana taxa was independent of phylogenetic associations. In Na, TPI activity and mRNA transcript accumulation as well as JA levels increased dramatically above wound-induced levels when the oral secretions (OS) from Manduca sexta larvae were introduced into wounds. This OS-mediated amplification of defense signaling and downstream response was also found in the tetraploid genomes but was absent from No; in No, OS treatment suppresses TPI mRNA accumulation and activity and does not increase JA accumulation. Hence, the tetraploids retained components of Na's signaling system, but lost Na's TPI genes and used No's TPI genes to retain a functional TPI defense system, underscoring the genomic flexibility that enables complex polygenic traits to be retained in allopolyploid species.
