more transcriptional factors involved lead to quick or slow phenotype transition?

Question

[pengchy]

As the title says. I have found that one phenotype transition has more TF genes involved while the reverse process need less TFs. Also, these two processes have different rates of transition. So, I wonder if there was any papers describing the relationship between the number of involved TFs and the rate of phenotype change?

Thank you! Pengcheng

There is a classical example - a sea star and a sea urchin

Caught in the evolutionary act: Precise cis-regulatory basis of difference in the organization of gene networks of sea stars and sea urchins

As far as I remember, the article describes that TFs working

at different development stages lead to different phenotypes.

I am not sure their amount matter.
