title: No Escape: The Influence of Substrate Sodium on Plant Growth and Tissue Sodium Responses

description: This dataset contains data from a systematic review carried out to
 understand substrate sodium's influence on plant growth and sodium
 accumulation strategies.  Accordingly, we carried out a
 systematic review of plants’ responses to variation in substrate sodium
 concentrations. We compared biomass and tissue-sodium
 accumulation among 107 cultivars or populations (67 species in 20 plant
 families), broadly expanding beyond the agricultural and model taxa for
 which several generalizations previously had been made. We hypothesized a
 priori response models for each population’s growth and sodium
 accumulation as a function of increasing substrate NaCl and used Bayesian
 Information Criterion to choose the best model. Additionally, using a
 phylogenetic signal analysis, we tested for phylogenetic patterning of
 responses across taxa. The influence of substrate sodium on
 growth differed across taxa, with most populations experiencing
 detrimental effects at high concentrations. Irrespective of growth
 responses, tissue sodium concentrations for most taxa increased as sodium
 concentration in the substrate increased. We found no strong associations
 between type of growth response and type of sodium accumulation response
 across taxa. Although experiments often fail to test plants across a
 sufficiently broad range of substrate salinities, non-crop species tended
 toward higher sodium tolerance than domesticated species. Moreover, some
 phylogenetic conservatism was apparent, in that evolutionary history
 helped predict the distribution of total-plant growth responses across the
 phylogeny, but not sodium accumulation responses. Our study
 reveals that saltier plants in saltier soils prove to be a broadly general
 pattern for sodium across plant taxa. Regardless of growth responses,
 sodium accumulation mostly followed an increasing trend as substrate
 sodium levels increased.
description: This dataset was collected from 48 studies and incorporated raw
 data dorm 107 populations, in 66 species across 20 plant families. We used
 a PRISMA protocol to perform a systematic search in Web of Science add
 rigorously selected articles that fitted our selection criteria. The
 dataset has 8 tables that are described as follow:

 Information S1: Figure S1: </b>Populations’ responses to increasing
 substrate NaCl concentrations. Above- (a) and belowground (b) relative
 biomass growth responses across NaCl treatments for each population
 sampled in the study. Negative and positive values represent a growth
 inhibition or an increase, respectively, in growth relative to control
 NaCl substrate concentrations.  Also, the effect of NaCl treatments on
 above- (c) and belowground (d) sodium accumulation across increasing NaCl
 substrate concentrations for each population. The main data shown cover
 the range from 0 to 600 mM treatments of NaCl. An inset with the complete
 dataset and treatments is included with each panel. Colors represent the
 responses that describe biomass growth and sodium accumulation responses,
 as in Tables 1 and 2. <b>Supporting Information:
