a

The modulation is depicted by up arrows (RIUR) and down arrows (RIDR) as follows: a 2.5- to 5-fold effect is depicted as one arrow, a 6- to 15-fold effect by two arrows, and a 16-fold or greater effect as three arrows. No arrow indicates there was a less-than-2.5-fold difference.

b

In four cases, indicated by single asterisks, the introduction of the mutations changed RITM from strong RIDR to no effect.

c

In four cases, indicated by double asterisks, the mutation of a global regulator either blocked RIUR or switched the response from RIUR to RIDR, indicating that the regulator was involved in RIUR for that promoter.
