The cis-prenyltransferase protein family in Taraxacum koksaghyz.

ABSTRACT: The cis-prenyltransferase (cisPT) enzyme family is involved in diverse biological processes that require the synthesis of linear isoprenoid compounds. Taraxacum koksaghyz is a rubber-producing species and potential crop that has eight cisPT homologs (TkCPT1-8) but their distribution and functions are unclear. We compared the structural organization and sequence homology of the proteins, and defined two groups: TkCPT and TkCPT-like (TkCPTL) proteins that form heteromeric cisPT enzymes (TkCPT1-4), and TkCPT proteins that function as homomeric cisPTs (TkCPT5-8). We found that TkCPT1 and TkCPT2 are predominantly expressed in latex whereas TkCPT3 and TkCPT6-8 are predominantly expressed in leaves. TkCPT4 was constitutively expressed in all T. koksaghyz tissues and TkCPT5 mRNA was detected in fl
