Editing Gall (section)

=== Structure ===

In a general [[gall wasp]] gall, the outermost layer is the epidermis followed by outer cortex and then inner cortex. In some galls these two cortex layers are separated by a lignified layer. The innermost part of a gall is the larval chamber. The nutritive layer is situated between the larval chamber and the inner cortex. There is a nutritional gradient (high to low) from inside to outside of the gall while defense gradient to the opposite direction.<ref name="Schultz 2022">{{Cite journal |last1=Schultz |first1=Jack C. |last2=Stone |first2=Graham N. |date=June 2022 |title=A tale of two tissues: Probing gene expression in a complex insect-induced gall |journal=Molecular Ecology |language=en |volume=31 |issue=11 |pages=3031–3034 |doi=10.1111/mec.16482 |pmc=9321127 |pmid=35466464}}</ref><ref name="Williams 1994">{{Cite book |editor-last=Williams |editor-first=Michele A.
