The invention discloses a
rubus cochinchinensis efficient genetic transformation method based on RUBY
reporter gene and
agrobacterium rhizogenes mediation, which realizes that the transformation period is shortened to be within 15 days and the
transformation efficiency is improved to be more than 60% through direct explant treatment under a non-
tissue culture condition. The method comprises the following specific steps: 1) preparing an explant material; (2) constructing an RUBY carrier and transforming
agrobacterium rhizogenes; (3) infecting the explant by utilizing
agrobacterium rhizogenes carrying a
target gene; (4) co-culturing after infection and carrying out RUBY
visual screening; 5) positive root
molecular biology verification; (6) inducing positive roots into buds; according to the method, induction of the positive
callus, the positive root and the positive
bud of the
rubus coreanus stem segment under the non-
tissue culture condition is successfully achieved, a stable and efficient genetic transformation
system is constructed, the method has the remarkable advantages of being easy and convenient to operate, low in cost, wide in applicability, high in reproducibility and the like, and a key
technical support is provided for
molecular breeding of the
rubus coreanus.
