Intraspecific variation in immune gene expression and heritable symbiont density
H. L. Nichols, E. B. Goldstein, O. Saleh Ziabari, B. J. Parker
This paper shows that variation in immune gene expression and symbiont density in pea aphids is linked to host genetic differences and symbiont species, with Regiella suppressing immune genes to increase its density.
