Amino acids in inner bark of loblolly pine, as affected by the southern pine beetle and associated microorganisms

Abstract

Infection with two beetle-associated fungi and the beetle-microorganism complex resulted in no qualitative changes in free amino acids and minor changes in protein-bound amino acids. Concentration of most free amino acids and soluble N was decreased, however, and that of most protein-bound amino acids, insoluble N, and total N was increased.
