Alkaloid profiles of sequenced isolates.^a

aStrains are abbreviated as follow: Cpu = Claviceps purpurea 20.1, Cfu = C. fusiformis PRL 1980, Cpa = C. paspali RRC-1481, Eam = Epichloë amarillans E57, Ebe = E. brachyelytri E4804, Eel = E. elymi E56, Ef1 = E. festucae Fl1, Ef2 = E. festucae E2368, Egl = E. glyceriae E2772, Et8 = E. typhina E8, Et5 = E. typhina E5819, Nga = N. gansuense E7080, Ngi = N. gansuense var. inebrians E818, Nun = N. uncinatum E167, Pip = P. ipomoeae IasaF13. Symbols: + = present, (+) = intermediate inferred to be synthesized because downstream product is present, − = not predicted and not detected, (−) = predicted but not detected, nt = predicted but not tested, ERA = ergotamine, ERB = ergobalansine, ERC = ergocryptine, ERV = ergovaline. Blank cells indicate compounds not predicted from genotype, and not tested. bIdentification of IDT-436 and terpendoles E, I, J, K, M, M, and A are tentative because authentic standards are unavailable.
