Abstract: | Summary Genetic transformation provides the means for modifying single horticultural traits in perennial plant cultivars without altering
their phenotype. This capability is particularly valuable for perennial plants and tree species in which development of new
cultivars is often hampered by their long generation time, high levels of heterozygosity, nucellar embryony, etc. Most of
these conditions apply to many tropical and subtropical fruit crops. Targeting specific gene traits is predicated upon the
ability to regenerate elite selections of what are generally trees from cell and tissue cultures. The integrity of the clone
would thereby remain unchanged except for the altered trait. This review provides an overview of the genetic transformation
of perennial tropical and subtropical fruit crops, i.e., citrus (Citrus spp.), banana and plantain (Musa groups AAA, AAB, ABB, etc.), mango (Mangifera indica L.), pineapple (Ananas comosus L.), avocado (Persea americana Mill.), passion fruit (Passiflora edulis L.), longan (Dimocarpus longan Lour.), and litchi (Litchi chinensis Sonn.). |
