Blues Chord progressions in minor key

[bctoner]

I understand that a Blues 1,4,5, progression using 7th chords is accually three different key changes. Such as A7, D7, E7 and in general one might say that is a progression in the key of A even thought is not. What would the chords be if it was in a minor key such as Aminor. In the scale of A there is is three minors B,C, and F but as a blues in the key of A would they most likely play Amin, Dmin, and Emin.

I talk about this in Fretboard Theory Chapter 8: Modes. On page 114 under the heading Modes and the Blues I write...

"If a blues song has a minor chord that functions as the
root, then it’s either in Dorian or Aeolian mode. Although
blues players rarely think of it as such because they so often
limit themselves to using only pentatonic scales. If
you compare the notes of the minor pentatonic to either
an Aeolian or Dorian scale, then you’ll realize that all the
pentatonic notes are in both modes. So the pentatonic
ends up being a simplified version of the parent major
scale either way. The modal scale includes two additional
scale degrees (the 2nd and 7th counting from the modal
root) that offer more melodic possibilities. Two good
examples of blues songs in Aeolian mode are “The Thrill
Is Gone” by B.B. King and “Maria, Maria” by Santana."
