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.
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: Supporting Information S1: Figure
S1: 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. Supporting Information: Table S1: Summary of populations’
responses. Each population response was classified using a model selection
approach related to a priori predictions. Supporting Information: Table
