This protocol applies to the characterization of genome structure and evolution of M. acuminata and M. balbisiana genomes; construction of physical maps around markers of interest and QTLs; comparative genomic studies with other monocot species; and study of banana streak virus (BSV) integration patterns in banana nuclear genomes. The principle, key advantages, starting plant material, time required and expected results are presented. Materials and methods. This part describes the required materials, and the protocols for isolation and lysis of banana nuclei; high-molecular-weight (HMW) DNA Hind III digestion and pulsed-field gel electrophoresis (PFGE) analysis; large-scale HMW DNA Hind III digestion and ligation to the pINDIGOBAC-5 vector; and analysis of recombinant BAC clones. It mentions the main problems which can occur. Results. The described protocols will enable the efficient construction of BAC libraries from Musa species. These libraries can be used to construct physical maps and select specific genomic regions to be sequenced.  aelectrophoresis  aDNA  aMusa sp  aGenetic map  aGenetic marker  aMethod1 aVILARINHOS, A.
