“…As well, some species of Oenothera may have evolved alternative defensive strategies in different biogeographic regions, such as greater investment in induced defenses (Anstett et al. ), tolerance (Puentes and Johnson ), or avoidance (Agrawal et al. ), which could obscure latitudinal gradients in constitutive defenses like those studied here.…”

“…These mechanisms are not mutually exclusive, and could lead to complex patterns of selection across space that do not closely follow latitudinal gradients. As well, some species of Oenothera may have evolved alternative defensive strategies in different biogeographic regions, such as greater investment in induced defenses (Anstett et al 2016a), tolerance (Puentes and Johnson 2016), or avoidance , which could obscure latitudinal gradients in constitutive defenses like those studied here.…”

Plant defenses against herbivores are predicted to evolve to be greater in warmer climates, such as lower latitudes where herbivore pressure is also thought to be higher. Instead, recent findings are often inconsistent with this expectation, suggesting alternative hypotheses are needed. We tested for latitudinal gradients in plant defense evolution at the macroevolutionary scale by characterizing plant chemical defenses across 80 species of the evening primroses, spanning both North and South America. We quantified phenolics in leaves, flowers, and fruits, using advanced analytical chemistry techniques. Dominant individual ellagitannin compounds, total concentrations of ellagitannins, flavonoids, total phenolics, and compound diversity were quantified. Variation in these compounds was predicted with latitude, temperature, precipitation, and continent using phylogenetic generalized least squares (PGLS) multiple regression models. Latitude did not strongly explain variation in chemical defenses. Instead, fruit total ellagitannins, oenothein A, and total phenolics were greater in species inhabiting regions with colder climates. Using analytical chemistry and 80 species in two continents, we show that contrary to classic predictions, concentrations of secondary metabolites are not greater at lower latitudes or in warmer regions. We propose higher herbivore pressure in colder climates and gradients in resource availability as potential drivers of the observed patterns in Oenothera.

“…Oenothera biennis preferentially occupies open and disturbed habitats (e.g. fields, roadsides, and lakeshores) ( Puentes and Johnson, 2016 ), and severely damages the local natural ecosystem ( Thijs et al., 2012 ). Previous studies have confirmed that high leaf area, the reproductive period in late summer, and long roots were key traits for the successful colonization of invasive O. biennis ( Stanisci et al., 2010 ).…”

Biological invasions and soil salinization have become increasingly severe environmental problems under global change due to sea-level rise and poor soil management. Invasive species can often outcompete native species, but few studies focus on whether invasive alien species are always superior competitors under increasing stressors. We grew an invasive grass species, Oenothera biennis L., and three native grass species (Artemisia argyi Lévl. et Vant., Chenopodium album L., and Inula japonica Thunb.) as a monoculture (two seedlings of each species) or mixture (one seedling of O. biennis and one native species seedling) under three levels of salt treatments (0, 1, and 2 g/kg NaCl) in a greenhouse. We found that invasive O. biennis exhibited greater performance over native C. album and I. japonica, but lower performance compared to A. argyi, regardless of the soil salinity. However, salinity did not significantly affect the relative dominance of O. biennis. Interspecific competition enhanced the growth of O. biennis and inhibited the growth of I. japonica. Although O. biennis seedlings always had growth dominance over C. album seedlings, C. album was not affected by O. biennis at any salt level. At high salt levels, O. biennis inhibited the growth of A. argyi, while A. argyi did not affect the growth of O. biennis. Salt alleviated the competitive effect of O. biennis on I. japonica but did not mitigate the competition between O. biennis and the other two native species. Therefore, our study provides evidence for a better understanding of the invasive mechanisms of alien species under various salinity conditions.

“…For example, these resources allowed the first test in plants of multiple predictions stemming from theory of the evolution of sex [40,[44][45][46][47][48][49][50][51]. Recent research also led to important advances in the study of plant defense evolution [52][53][54][55][56][57][58][59], and eco-evolutionary dynamics within communities [60][61][62][63][64][65][66][67][68]. Further, genomic tools have made it possible to determine the role of nuclear-organellar incompatibilities in speciation [69,70], mechanisms of mutations in plastid genome evolution [71], novel mechanisms in chloroplast gene expression [72], and the identification of chloroplast genes involved in plastid transmission [73].…”

The plant genus Oenothera has played an important role in the study of plant evolution of genomes and plant defense and reproduction. Here, we build on the 1kp transcriptomic dataset by creating 44 new transcriptomes and analyzing a total of 63 transcriptomes to present a large-scale comparative study across 29 Oenothera species. Our dataset included 30.4 million reads per individual and 2.3 million transcripts on average. We used this transcriptome resource to examine genome-wide evolutionary patterns and functional diversification by searching for orthologous genes and performed gene family evolution analysis. We found wide heterogeneity in gene family evolution across the genus, with section Oenothera exhibiting the most pronounced evolutionary changes. Overall, more significant gene family expansions occurred than contractions. We also analyzed the molecular evolution of phenolic metabolism by retrieving proteins annotated for phenolic enzymatic complexes. We identified 1,568 phenolic genes arranged into 83 multigene families that varied widely across the genus. All taxa experienced rapid phenolic evolution (fast rate of genomic turnover) involving 33 gene families, which exhibited large expansions, gaining about 2-fold more genes than they lost. Upstream enzymes phenylalanine ammonia-lyase (PAL) and 4-coumaroyl: CoA ligase (4CL) accounted for most of the significant expansions and contractions. Our results suggest that adaptive and neutral evolutionary processes have contributed to Oenothera diversification and rapid gene family evolution.
