Table 2. Transformation efficiency of ‘Hamlin’ sweet orange from 1 gram of suspension cell derived cultures.

Transformation system	VvmybA1-negative embryos a	VvmybA1-positive embryos a	VvmybA1-positive shoots (Plant recovery efficiency (%))b
Suspension Cells	74	56	18 (32)
Protoplast	194	21	11 (52)

^a Data from three independent experiments. Results indicate the total number of embryos produced (VvmybA1 positive and negative)

^b Plant recovery efficiency was calculated as the total number of VvmybA1-positive shoots/total number of VvmybA1-positive embryos produced X 100.
