Gene Ontology:

• GO:0009534  — located in — chloroplast thylakoid
• GO:0009507  — located in — chloroplast
• GO:0009793  — acts upstream of or within — embryo development ending in seed dormancy
• GO:0009570  — located in — chloroplast stroma
• GO:0003729  — enables — mRNA binding
• GO:0031425  — acts upstream of or within — chloroplast RNA processing
• GO:0003723  — enables — RNA binding
• GO:0005515  — enables — protein binding

Germplasm Phenotype:

• CS16015  — Embryo defective; initiated cotyledons and continued growth and cell division beyond heart stage. Embryos elongated and developed a clear hypocotyl, but featured dramatically stunted cotyledons. Domed shoot apex.
• CS16015  — embryo defective; developmental arrest of mutant embryos
• SAIL_896_E10  — Albino cotyledons. In heterozygous acm1/+ siliques, some of the ovules were white, segregating 1:3 for white:green.
• emb1270-1  — Embryo/seedling lethal. Mutant embryos can be cultured on sucrose containing MS media but they produce albino leaves and then die.
