    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
    AtBAM3; BAM3; BETA-AMYLASE 3; BETA-AMYLASE 8; BMY8; chloroplast beta-amylase; CHLOROPLAST BETA-AMYLASE; DL4575C; FCAALL.5
    Summary
    Encodes a beta-amylase targeted to the chloroplast. Transgenic BMY8 RNAi lines fail to accumulate maltose during cold shock suggesting that maltose accumulation coincides with BMY8 expression. Apart from maltose, the sugar content of the RNAi lines were similar to wildtype (glucose and sucrose unaffected).
