The last decade has witnessed a series of advances in banana and plantain research that are expected to catalyse progress in a major field of banana breeding: the development of Musa varieties resistant to various biotic and abiotic stresses. The contributions of molecular biologists to this advancement included the generation of informative DNA markers for the identification of the A and B genomes, the detection of genetic diversity in germplasm, the diagnosis of varieties and cultivars and levels of heterozygosity, the origin of the B genome in hybrids, the establishment of genetic maps and the construction of a bacterial artificial chromosome (BAC) library with approximately fivefold genome coverage. Useful genes and promoters have also become available for the effective transformation of target cultivars using, for example, specific Agrobacterium tumefaciens strains and optimised protocols for regeneration of embryogenic cell suspension cultures. Transgenic plants have been tested for the presence and expression of foreign genes.
