There are two instances of callus, one developing as a result of injury, 
and another instance is the same as you have. So you may like to add both.

In the definition you may want to rephrase " cell aggregates" to 
undifferentiated mass of cells/tissue.

Under the comments in place of Arabidopsis, can we say Brassicaceae?

This still needs further discussion, wait until we have come to a 
conclusion. I am not sure if we can call XX-primordium as an instance of 
XX, where XX is a mature organ.
