Nature Communications, Published online: 03 May 2026; doi:10.1038/s41467-026-72738-5 The malto-oligosaccharides (MOS) serve as essential primers for starch synthesis in higher plants. Authors demonstrate that two enzymes, PHS1 and DPE1, form a binary complex and coordinately promote MOS synthesis as a key initial step in starch biosynthesis.
