Background: In Algeria, date palm is currently confronted to the Bayoud disease. Biotechnological tools such as protoplasts fusion can appear as an alternative to ensure rapid multiplication and improvement of this species. Objectives: Callogenesis induction in protoplasts isolated from embryogenic callus of three date palm cultivars. Materials and Methods: Some factors influencing the isolatio...

Utilizing somatic cell hybridization, we have developed a monoclonal antibody that interacts only with cells of the monocyte/macrophage (M phi) line and not with other myeloid or lymphoid cells. This antibody detects a 120,000-dalton determinant present on 37 +/- 2.8% of the peripheral blood M phi from several (HLA-DR)-disparate individuals and only depicts a subpopulation (approximately 30%) o...
