The invention discloses a tamarix hispida instantaneous transformation method, and relates to a
plant instantaneous transgenosis method. The invention aims at solving the problems that an existing tamarix hispida stable transformation cycle is too long and an original tamarix hispida instantaneous transformation method is low in
transformation efficiency. The method comprises the following steps: I, selecting tamarix hispida
tissue culture seedlings obtained from subculture, and soaking the selected tamarix hispida
tissue culture seedlings in high-permeability treatment liquid; II, rapidly transferring the tamarix hispida
tissue culture seedlings which have undergone high-permeability treatment into
agrobacterium tumefaciens infection liquid which contains a
target gene, conducting vacuumizing in a
vacuum pump and conducting infection in a constant-temperature oscillator; and III, taking out the infected tissue culture seedlings, washing the tissue culture seedlings, sucking water, inserting the tissue culture seedlings into a
sodium co-culture medium and conducting co-culture. With the application of the method, the instantaneous
transformation efficiency of the tamarix hispida is greatly improved. On the basis of an
enzyme activity determination result of a
marker gene GUS instantaneously transformed
gene, it shows that the method, in comparison with the original tamarix hispida instantaneous transformation method, can improve a GUS activity by 2.45 times. The method provided by the invention is applicable to the field of
plant instantaneous transgenosis.
