Hierarchical clustering of glucosinolate profiles. Fourteen compounds were identified across individuals of P. cheesemanii (CH, n = 12), P. exile (EX, n = 13) and P. novae-zelandiae (NZ, n = 12). Data used for hierarchical clustering represent proportions from total contents; for comparisons of concentrations see additional file 2, figure S1. Note that CH and NZ share their two major compounds allyl and S-2OH3-butenyl glucosinolate despite being less closely related than CH and EX. *The glucosinolate profiles for P. novae-zelandiae and P. cheesemanii were independently confirmed during the analysis of glucosinolate breakdown products in both species (table 5). Abbreviations: 3MTP, 3-methylthiopropyl glucosinolate; 4MTB, 4-methylthiobutyl glucosinolate; 3MSOP, 3-methylsulfinylpropyl glucosinolate; 4MSOB, 4-methylsulfinylbutyl glucosinolate; allyl, 2-propenyl glucosinolate; 3-butenyl, 3-butenyl glucosinolate; S-2OH3-butenyl, S-2-hydroxy-3-butenyl glucosinolate; 6MSOH, 6-methylsulfinylhexyl glucosinolate; 7MTH, 7-methylthioheptyl glucosinolate 7MSOH, 7-methylsulfinylheptyl glucosinolate; 8MSOO, 8-methylsulfinyloctyl glucosinolate; 1MOI3M, 1-methoxy-indolyl-3-methyl glucosinolate; 4OHI3M, 4-hydroxy-indolyl-3-methyl glucosinolate, 4MOI3M, 4-methoxy-indolyl-3-methyl glucosinolate.
