abscission

Not abscisic acid, the one that “abscission zone” would seem to imply.

When days shorten, the leaves begin to accumulate more of this chemical during the night, stimulating the formation of an abscission layer.

The abscission process leaves behind the primary cilium and any signaling systems localized to the cilium.

Additional insights important to TAG biosynthesis, fruit ripening and abscission are provided in .

Students worked with collaborative teams to develop innovative methods for quantifying leaf color change and abscission in campus trees.
