Alu sequences are a major repetitive element of the primate genome. To
date Alu sequences have seldom been reported in plant genomes. We rep
ort here an inter-Alu PCR like genomic profiling in banana using a sin
gle primer designed from a human Alu sequence. The different Musa spec
ies involved in the complex genome of banana cultivars can thus be dis
criminated. The use of this technique for monitoring germplasm or geno
typing cultivars is discussed.
