What would be your recommended term for plant's 'gall tissue' (MAT_00003541) if I were to map to PO?

[cooperl09]

There are many different types of plant galls that can arise as a result of insects or pathogens, including, of course, Agrobacterium tumefaciens (causal agent of crown gall)

The term 'gall tissue' in the MAT is not defined: (http://www.ontobee.org/ontology/MAT?iri=http://purl.obolibrary.org/obo/MAT_0000351), so it's a bit difficult to know exactly what the term is referring to but the closest term in the PO would be:

plant callus: A portion of plant tissue (PO:0009007) that consists of mass of undifferentiated plant cells (PO:0009002).
Comment: Consists primarily of parenchyma cells but may contain other cell types as the callus begins to differentiate. May be formed as a result of wounding or may develop in culture.

We may need a generic term Plant Gall...A ground tissue generated in response to an external factor. And then have multiple subclass for
-bacteria induced plant gall
-insect induced plant gall
-etc.

I think that '[portion of] gall tissue' should be added to the Plant
Anatomy Ontology -- perhaps as a sibling of 'plant callus'

@adeans has a proposed gall ontology OBOFoundry/OBOFoundry.github.io#2522 he will be attending the planteome workshop. I suggest this ticket is updated and closed after that workshop. I am curious to see the plan - what will the mutual dependencies be? Will PO import GALLONT or vice versa...?

Revising the definition after further discussions with @adeans
plant gall (PO:0025626):
A multi-tissue plant structure (PO:0025496) that develops in response to a plant animal damage (PSO:0000004).

Further revision:
plant gall (PO:0025626): A multi-tissue plant structure (PO:0025496) that develops in response to a biotic stress (PSO:0000011).
