Characterization and systematic implications of the diversity in timing of programmed cell death of the suspensors in Leguminosae.

Abstract excerpt

PREMISE OF THE STUDY: In angiosperm seeds, the developing embryo acquires nutrients via a suspensor that typically undergoes programmed cell death (PCD) at the early cotyledon stage. However, in Leguminosae (the third largest angiosperm family), the suspensors can disappear at the heart-shaped stage (i.e., prior to the cotyledon stage) or still persist at the cotyledon stage. Here, in a comprehensive survey of...
