Publisher Summary This chapter investigates the genetic characters of coffee, which is a woody perennial plant. The genus Coffea(C) is polymorphic. All species so far studied have been found to have 2n=22 chromosomes with the exception of C. arabica that has 2n=44 chromosomes. The haploid form of C.

2000Les essais de transformation génétique ont été conduits sur des embryons somatiques de Coffea canephora Pierre, Coffea arabica L. et de l'hybride interspécifique Arabusta, en utilisant Agrobacterium rhizogenes A4 ou Agrobacterium tumefaciens LBA4404. Deux plasmides ont été utilisés, portant l'un les gènes uidA (GUS) et NPTII ou l'autre, le gène csr 1-1
