Data from: Plant functional traits and environmental conditions shape community assembly and ecosystem functioning during restoration

Chad R. Zirbel, Tyler Basset, Emily Grman, Lars A. Brudvig & Tyler Bassett
Recovering biological diversity and ecosystem functioning are primary objectives of ecological restoration, yet these outcomes are often unpredictable. Assessments based on functional traits may help with interpreting variability in both community composition and ecosystem functioning because of their mechanistic and generalizable nature. This promise remains poorly realized, however, because tests linking environmental conditions, functional traits, and ecosystem functioning in restoration are rare. Here, we provide such a test through what is to our knowledge the...

Data from: Using genomic location and coalescent simulation to investigate gene tree discordance in Medicago L.

Filipe Sousa, Yann J. K. Bertrand, Jeff J. Doyle, Bengt Oxelman & Bernard E. Pfeil
Several well-documented evolutionary processes are known to cause conflict between species-level phylogenies and gene-level phylogenies. Three of the most challenging processes for species tree inference are incomplete lineage sorting, hybridization and gene duplication, which may result in unwarranted comparisons of paralogous genes. Several existing methods have dealt with these processes but none has yet been able to untangle all three at once. Here, we propose a stepwise method by which these processes can be discerned...

Data from: A modified GC-specific MAKER gene annotation method reveals improved and novel gene predictions of high and low GC content in Oryza sativa

Megan J. Bowman, Jane A. Pulman, Tiffany L. Liu & Kevin L. Childs
Background: Accurate structural annotation depends on well-trained gene prediction programs. Training data for gene prediction programs are often chosen randomly from a subset of high-quality genes that ideally represent the variation found within a genome. One aspect of gene variation is GC content, which differs across species and is bimodal in grass genomes. When gene prediction programs are trained on a subset of grass genes with random GC content, they are effectively being trained on...

Data from: The edaphic environment mediates flowering-time differentiation between adjacent populations of Leptosiphon parviflorus

Emily L. Dittmar & Douglas W. Schemske
Flowering time is an important life history trait in plants that often affects fitness. The optimal time to flower may be influenced by trade-offs between flowering time and growth-related traits and is thus likely to differ among habitats. Because flowering-time differences between populations can also reduce gene flow, understanding the factors that contribute to variation in flowering time among closely adjacent populations that experience gene flow is of particular interest. Plant adaptation to different edaphic...

Data from: Effect of expanded variation in anther position on pollinator visitation to wild radish, Raphanus raphanistrum

Yuval Sapir, Keith Karoly, Vanessa A. Koelling, Heather F. Sahli, Frances N. Knapczyk & Jeffrey K. Conner
Background and Aims: Plant-pollinator interactions shape the evolution of flowers. Floral attraction and reward traits have often been shown to affect pollinator behavior, but the possible effect of efficiency traits on visitation behavior has rarely been addressed. Here we tested for the effect of anther position, usually considered a trait that influences efficiency of pollen deposition on pollinators, on pollinator visitation rates and visit duration in flowers of wild radish, Raphanus raphanistrum. Methods: We used...

Data from: Heterochronic developmental shifts underlie floral diversity within Jaltomata (Solanaceae)

Jamie L. Kostyun, Jill C. Preston & Leonie C. Moyle
Background: Heterochronic shifts during mid- to late stages of organismal development have been proposed as key mechanisms generating phenotypic diversity. To determine whether late heterochronic shifts underlie derived floral morphologies within Jaltomata (Solanaceae)—a genus whose species have extensive and recently evolved floral diversity—we compared floral development of four diverse species (including an ambiguously ancestral or secondarily derived rotate, two putatively independently evolved campanulate, and a tubular morph) to the ancestral rotate floral form, as well...

Domesticated species are impacted in unintended ways during domestication and breeding. Changes in the nature and intensity of selection impart genetic drift, reduce diversity, and increase the frequency of deleterious alleles. Such outcomes constrain our ability to expand the cultivation of crops into environments that differ from those under which domestication occurred. We address this need in chickpea, an important pulse legume, by harnessing the diversity of wild crop relatives. We document an extreme domestication-related...
