a Endophytes that are known hybrids = (H); b Detection methods for the EAS genes DG = draft genome, G = genome, GT = PCR-based genotyping; c Number of independent strains evaluated. Alkaloids are abbreviated CC = chanoclavine I, ERV = ergovaline, EN = ergonovine, LAH = lysergic acid α-hydroxyethylamide, and are in bold face (product produced) or regular type (product predicted but not yet tested), or in parentheses (product predicted but undetected). 0 = No EAS genes identified, 0* = contains only remnants of EAS clusters; 0 and 0* are unable to produce ergot alkaloids.
