We have isolated several clones containing Xenopus histone genes from genomic libraries of X. laevis and X. borealis DNA. Each genomic clone has been mapped and the positions of 26 histone genes in seven laevis clones and 5 histone genes in one borealis clone have been determined. In laevis, the histone gene clusters show considerable variation in gene order within a single individual. When the cloned DNAs were microinjected into the nucleus of Xenopus oocytes, expression of cloned genes at the transcriptional and translational level was readily detectable. Previously unknown histone variants were revealed by the microinjection experiments.
