Table 2. List of Essential Genes in 10 Parasitic Orobanchaceae.
| Gene Class | Gene IDs | Remarks |
|---|---|---|
| Protein genesa | matK, rpl16, rpl2, rpl20, rpl33, rpl36, rps11, rps12, rps14, rps18, rps2, rps4, rps7, rps8, ycf1, ycf2 | In Phelipanche, ycf1 is fragmented and shows strong sequence divergence and therefore may be a pseudogene. |
| tRNAb | trnDGUC, trnEUUC, trnfMCAU, trnHGUG, trnICAU, trnLCAA, trnLUAG, trnMCAU, trnNGUU, trnPUGG, trnQUUG, trnSGCU, trnSUGA, trnWCCA, trnYGUA | trnICAU exists in two divergent copies in M. californica. |
| rRNA | rrn16, rrn23, rrn4.5, rrn5 | In Phelipanche, one rRNA gene set is deleted and rrn16 is partially duplicated in the LSC; one copy of rrn16 is deleted from the O. gracilis plastome. |
a
accD and clpP await experimental verification of functionality in Phelipanche and S. americana.
b
trnSUGA may be a pseudogene in C. americana.
