Beauveria bassiana isolates have been used in integrated pest management, but little consideration has been given to the studies on fungal gene expressions and their functions. In this work, to determine the functions of genes, B. bassiana ERL1170 was transformed by restriction enzyme-mediated integration method, where pABeG with bar gene was used as a transformation vector. Among seven hundred of transformants, morphologically different ERL1170-pABeG-#160 transformant, particularly dysfunctional in conidiogenesis. The transformant had yellow hyphal growth on fourth strength Sabouraud dextrose agar (SDA/4) and produced very small amount of conidia (<1.0×105 conidia/cm2 agar) in 7 days, whereas wild type had white mycelial growth and significantly greater conidia (3.6×106 conidia/cm2 agar). Additionally under microscopic observation, hyphae of #160 seemed like indian club, compared to the straight forms of wild type hyphae. The next work is figure out possible genes contributing the conidiogenesis of B. bassiana.

Ginseng(Panax ginseng C.A. Meyer) is a perennial herbaceous plant which grows very slowly. It takes about 3 to 4 years from seeding to collecting the ripe seeds and the ginseng propagation is very difficult. and so, it is very difficult to breed ginseng plant. Ginseng tissue culture was started from at 1960, and ginseng commercial product by in vitro callus culture was saled, however upto now, regenerants were not planted to soil normally. Recently, plant genetic engineering to produce transgenic plants by introducing useful genes has been advanced greatly. In a present paper, transformation of ginseng plants was achieved by co-cultivation with Agrobacterium harboring the binary vector coding Proteinase-II gene, which confer resistant or tolerant to insect pests, The binary vector for transformation was constructed with disarmed Ti-plasmid and with double 35S promoter. The NPT II gene and introduced genes of the transgenic ginseng plants were successfully identified by the PCR. Especially the transgenic ginseng plants were regenerated using new techniques such as repetitive single somatic embryogenesis.
