Raw data for Insight into GABA shunt-associated aldehyde dehydrogenases (ALDH) and stress responses of ALDH superfamily in moss and barley

Description of the data and file structure This supplementary dataset, integral to our research paper, contains data covering properties, interactions, and expression of studied aldehyde dehydrogenases (ALDHs). The dataset comprises gel permeation chromatography profiles of the studied plant ALDHs, microscale thermophoresis data used to describe the binding curves, as well as substrate screening profiles and saturation curves for the selected substrates, which were used to determine Km and kcat values. Thermal stability curves measured by nano-differential scanning fluorimetry are provided to show differences in stability. Quantitative PCR (qPCR) data are provided for the expression of barley ALDH gene superfamily and moss ALDH gene superfamily under various stress conditions and hormone treatments. Finally, for the aldh10A1, aldh21A1 and aldh5F2 mutants vs WT we provide RNA-seq data sets showing differentially expressed genes, phenotype and photosynthesis parameter data.
