PGDH1 is essential for Arabidopsis development.
Title: Arabidopsis phosphoglycerate dehydrogenase1 of the phosphoserine pathway is essential for development and required for ammonium assimilation and tryptophan biosynthesis.

Genetic and molecular evidence were provided for the essential role of EDA9 for embryo and pollen development.
Title: Identification of the phosphoglycerate dehydrogenase isoform EDA9 as the essential gene for embryo and male gametophyte development in Arabidopsis.

Data indicate that 3-phosphoglycerate dehydrogenases PGDH (At1g17745) and EDA9 (At4g34200) were expressed preferentially in roots while 3-PGDH (At3g19480) was expressed mainly in the aerial parts and was not expressed or very poorly in roots.
Title: Functional characterization of the plastidial 3-phosphoglycerate dehydrogenase family in Arabidopsis.
