^a Genes are arranged relative to cox1. Those encoded on the "-" strand are indicated with an asterisk (*).
^b T, and TA, refer to instances where incomplete stop codons are inferred.
^c Unassigned regions are identified by positive values. Negative values indicate overlap between adjacent genes. Values in brackets refer to %AT of the associated UR (only those UR >10 bp in length were analyzed).
^d For the unassigned region between trnV₁ and trnL_CUN spanning the pseudogene rrnL.
^e For the unassigned region between trnL_CUN and trnV₂ spanning the pseudogenes nad1 and rrnS.
