Official Symbol: PGI1
Official Full Name: phosphoglucose isomerase 1
Primary source: TAIR:AT4G24620
Locus tag: AT4G24620
See related: Araport:AT4G24620
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: F22K18.180; F22K18_180; PGI; PHOSPHO-GLC ISOMERASE; phosphoglucose isomerase 1; PHOSPHOGLUCOSE ISOMERASE PRECURSOR
Summary: The PGI1 gene encodes the plastid phospho-glucose (Glc) isomerase. While pgi1-1 mutant has a deficiency in leaf starch synthesis, it accumulates starch in root cap cells. Flowering time of the pgi1-1 mutant is significantly delayed under short-day conditions.
