Abjoint is a rare biological verb meaning to form by cutting off from a parent or mother cell, or to separate by the formation of a cross wall.
Plain-English explanation
Imagine a small outgrowth developing at the end or side of a cell. As it matures, a wall forms across the narrow connection. That wall establishes a boundary. The new unit may later be released or remain attached for a period of time.

Transitive and intransitive use
In a transitive construction, a parent structure abjoints a new unit. In an intransitive construction, the unit itself abjoints as the cross wall forms. Both usages focus on separation at a biological connection.
Why the word is uncommon today
Modern biological writing often names the exact process involved. Authors may prefer septation, delimitation, conidium formation, cell separation, or another term that identifies the structure and mechanism more precisely.
Words that are not synonyms
Adjoin means to be next to. Adjoint has specialized mathematical and scientific meanings. Disjoint means separate or non-overlapping. Abject describes degradation or extreme misery.
