These enzymes have also been detected in a wide range of plant organs and tissues undergoing developmental changes such as seeds, cotyledons, elongating epicotyls, and in freshly harvested asparagus spears.
In addition, they have four or five scaly leaves with lateral buds on their epicotyl.
The number of embryos developing an epicotyl was determined after 9 weeks in germination.
However, in coleoptiles, hypocotyls and epicotyls, gravity can be perceived along the whole length of the responding region and there is no such need to postulate any longitudinal transfer of a message.
At this stage, both the cotyledons and epicotyls (if visible) were green.
