Transgenic plants using superoxide dismutase gene of Lilium hybrid cultivar Marco Polo

摘要

The present invention is Lico Marcopolo Activity in transgenic potatoes prepared using plant transfer vectors recombined so that cDNA is expressed in the forward and reverse directions using Cu / Zn lily-superoxide dismutase (LSOD) genes expressed in scleroderma. The distribution of oxygen species is different, and their effects show opposite growth and tuber formation rates, and have a great effect on the vitrification rate during in-flight culture.;The Cu / Zn LSOD gene of the present invention increases the H ₂ O ₂ content and decreases the superoxide radical content in the plant when overexpressed, which inhibits growth in potatoes, resulting in a very good initial tuberization rate while shortening the length between the shoot and the node. By introducing a gene encoding the same into a plant cell, the development of a crude plant that can shorten the growth period and the reverse expression thereof can provide a potato plant of all species that can increase the growth period. In addition, the vitrification rate, which is a problem during mass cultivation in the cabin, can be drastically reduced, thereby increasing the purifying rate of aseptic seedlings and lowering the mortality rate during sowing of the in-flight plants, and can provide a transformed potato plant that is resistant to excessive moisture stress environment. .;Superoxide Dismutase, LSOD, Potato, Transgenic Potato Plant
