    The major capsid protein L1 of human papillomavirus type 16 (HPV16) was transiently expressed in tobacco (Nicotiana benthamiana and Nicotiana tabacum) and tomato (Lycopersicon esculentum) leaves using Agrobacterium tumefaciens. The expression vector pTV00 was derived from tobacco rattle virus (TRV). The highest L1 expression 15 mg g-1 was achieved when the coding sequence of L1 was optimized for expression in humans that caused an increase of the GC content from 38.2 % in wild type HPV16 to 64.1 % in optimized sequence. L1 monomers readily self-assembled into capsomeres and further into virus like particles (VLPs). Immunological characterization and electron microscopy showed that 89 % of L1 retained this structure also in extracts prepared from freeze-dried leaves. Plant expressed L1 was highly immunogenic without any additional adjuvant as vaccinated mice developed strong humoral and cellular immune response, comparable to that elicited by purified VLPs derived from insect cells.
