Editing Gall (section)

=== Morphogenesis ===

Gall [[morphogenesis]] involves the regulation of the organ on which the gall occurs while maintaining differentiation freedom. Gall development begins from a single or group of metaplasied cells and progresses through promoter-mediated cell expansion, cell multiplication, programmed differentiation, and control of symmetry.<ref name="Raman 2011" />

Plant response involves the establishment of metaplasied cells and localized metabolic changes to repair the wound and neutralize stress. [[Osmosis|Osmotic]] stress leads to the development of metaplasied cells, characterized by increased quantities of osmotically active material. The rejection response by the plant triggers the synthesis of defense compounds and [[enzyme]]s.<ref>{{Citation |last=Carmen |first=Cogălniceanu Gina |title=Electrical Control of Plant Morphogenesis |work=Plant Tissue Culture Engineering |pages=397–415 |url=http://dx.doi.org/10.1007/1-4020-3694-9_21 |access-date=2024-05-09 |place=Berlin/Heidelberg |publisher=Springer-Verlag |doi=10.1007/1-4020-3694-9_21 |doi-broken-date=1 November 2024 |isbn=1-4020-3594-2|url-access=subscription }}</ref><ref>{{cite book |last=Sinnott |first=Edmund W. |url=http://dx.doi.org/10.5962/bhl.title.4649 |title=Plant morphogenesis |date=1960 |publisher=McGraw-Hill |location=New York|doi=10.5962/bhl.title.4649 }}</ref>
