CC (PubMed:29476828). Involved in root growth and columella cells
CC organization (PubMed:29476828). May possess protein phosphatase
CC activity (By similarity). {ECO:0000250|UniProtKB:P0C089,

CC -!- PATHWAY: Phospholipid metabolism; phosphatidylglycerol biosynthesis;
CC phosphatidylglycerol from CDP-diacylglycerol: step 2/2.
CC {ECO:0000305|PubMed:29476828}.
CC -!- TISSUE SPECIFICITY: Expressed in stems, roots, flowers, mature seeds
CC and leaves. {ECO:0000269|PubMed:29476828}.
CC -!- DISRUPTION PHENOTYPE: No visible phenotype in the double mutant ptpmt1-
CC 1 ptpmt2-1 (PubMed:29476828). But plants lacking PTPMT1, PTPMT2 and
CC PGPP1 have strongly shorter roots associated with a defective order of
CC columella cells in the root apices, with stronger effect than in the
CC single mutant pgpp1-1 (PubMed:29476828). {ECO:0000269|PubMed:29476828}.
CC -!- SIMILARITY: Belongs to the protein-tyrosine phosphatase family. Non-
CC receptor class dual specificity subfamily. {ECO:0000305}.
