Divergent Iron Acquisition Strategies from Dust-Relevant Minerals in Marine Diatoms under Iron Limitation

Growth was monitored throughout the experimental period.Nutrient salt.xlsxThis file contains measurements of dissolved nutrient concentrations, including nitrate (N), phosphate (P), and silicate (Si), in all experimental treatments during incubation.OD600 + Total Chlorophyll.xlsxThis file contains optical density (OD600) measurements and total chlorophyll concentrations for all experimental treatments, providing physiological indicators of algal growth and photosynthetic status.Raw fastqThis folder contains the transcriptomic sequencing data generated from Thalassiosira pseudonana and Phaeodactylum tricornutum cultured with different iron-bearing mineral treatments.

These data were used for comparative gene expression analyses to investigate the molecular responses associated with mineral-derived iron utilization.Together, these datasets provide comprehensive mineralogical, geochemical, physiological, and transcriptomic information for investigating interactions between marine diatoms and iron-bearing minerals under controlled laboratory conditions. They support analyses of mineral properties, iron availability, algal growth, nutrient utilization, and cellular responses associated with mineral-derived iron acquisition.
