Description
Summary:Embryo and seed development are essential for the reproductive success of flowering plants. However, these processes remain underexplored in the Annonaceae family that belongs to the early-divergent angiosperm clade Magnoliid, and are characterized by the distinctive feature of ruminations in the seeds. To fill this knowledge gap, we conducted a study to characterize the embryogeny and seed development of Asimina triloba ("pawpaw"), the northernmost species of the mainly tropical family Annonaceae.
