A method for Agrobacterium-mediated transformation of Citrus and organogenic regeneration of transgenic plants is reported. Internodal stem segments were co-cultured with Agrobacterium harboring binary vectors that contained the genes for the scorable marker ß-glucuronidase (GUS) and the selectable marker NPT-II. A low but significant percentage (≤ 5%) of the shoots regenerated in the presence of 100 μg/ml kanamycin were GUS+. Polymerase chain reaction (PCR) analysis confirmed that GUS+ shoots contained T-DNA. Two plants established in soil were shown to be transgenic by Southern analysis.
