    Lineage
    Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
    Also known as
    ATSS1; MOP9.12; MOP9_12; SSI; starch synthase 1; STARCH SYNTHASE 1; SUPPRESSOR OF SALICYLIC ACID INSENSITIVE; SUPPRESSOR OF SALICYLIC ACID INSENSITIVITY 1
    Summary
    SSI is a plastidial enzyme and crucial for the synthesis of normal amylopectin in the leaves of Arabidopsis. The absence of SSI results in a deficiency in the number of shorter glucans which in turn affect the formation and connection of the amylopectin clusters in starch.
