Factory with journalist embedded (7)
I believe the answer is:
planted
'embedded' is the definition.
('plant' can be a synonym of 'embed')
'factory with journalist' is the wordplay.
'factory' becomes 'plant' (a manufacturing plant).
'with' says to put letters next to each other.
'journalist' becomes 'ed' (short for editor).
'plant'+'ed'='PLANTED'
(Other definitions for planted that I've seen before include "Put in the ground" , "Set in the soil for growth" .)
