Composition and Method for Prolonging the Shelf Life of Banana by Using Interfering RNA

A gene transformed method for banana, said transferring method comprising following steps:

• step 1 inducing somatic embryo:
• culturing fruit finger primodia or apical meristem in an inducing medium to induce the formation of somatic embryo cell;
• step 2 cocultivation with Agrobacterium:
• mixing somatic embryo cell obtained in step 1 and transformed Agrobacterium in an inducing medium to carry out co-culture transferring treatment;
• step 3 post-transfer screening:
• after cocultivation, shifting the transformed cell in an inducing medium containing suitable antibiotics to carry out the post-transfer screening;
• step 4 cultivating to a plant:
• shifting the screened transformed cell in an inducing medium containing suitable antibiotics, and cultivating for 6 to 8 months to obtain a transgenic plant.
