title: Data from: Identity recognition in response to different levels of genetic relatedness in commercial soya bean

description: Identity recognition systems allow plants to tailor competitive phenotypes
 in response to the genetic relatedness of neighbours. There is limited
 evidence for the existence of recognition systems in crop species and
 whether they operate at a level that would allow for identification of
 different degrees of relatedness. Here, we test the responses of
 commercial soya bean cultivars to neighbours of varying genetic
 relatedness consisting of other commercial cultivars (intraspecific), its
 wild progenitor Glycine soja, and another leguminous species Phaseolus
 vulgaris (interspecific). We found, for the first time to our knowledge,
 that a commercial soya bean cultivar, OAC Wallace, showed identity
 recognition responses to neighbours at different levels of genetic
 relatedness. OAC Wallace showed no response when grown with other
 commercial soya bean cultivars (intra-specific neighbours), showed
 increased allocation to leaves compared with stems with wild soya beans
 (highly related wild progenitor species), and increased allocation to
 leaves compared with stems and roots with white beans (interspecific
 neighbours). Wild soya bean also responded to identity recognition but
 these responses involved changes in biomass allocation towards stems
 instead of leaves suggesting that identity recognition responses are
 species-specific and consistent with the ecology of the species. In
 conclusion, elucidating identity recognition in crops may provide further
 knowledge into mechanisms of crop competition and the relationship between
 crop density and yield.
description: Experiment 1
 dataThis file contains all
 measurements and treatments for the first experiment in the study. Final
 root biomass is calculated by subtracting the weight of rocks from the
 initial measurement of root biomass. Cultivars a, b, and c, refer to OAC
 Wallace, OAC Calypso, and OAC Champion respectively. Any missing values
 refers to plants that died, did not germinate, or plant parts could not be
 retrieved because of damage.Data experiment 2
 responses of wild soybeanThis file contains
 measurements and treatments for responses of wild soybean to commercial
 neighbours. Only data from wild soybean plants was used in the analysis of
 this data set. Final root biomass is calculated by subtracting the weight
 of rocks from the initial measurement of root biomass. Cultivars w and c,
 refer to wild soybean and OAC Wallace respectively. Any missing values
 refers to plants that died, did not germinate, or plant parts could not be
 retrieved because of damage.Data experiment 2a dryad
