Biotechnological advances in species, and future perspectives.

is a large genus consisting of 230 species of trees and shrubs with multiple (ornamental, ethnobotanic and pharmacological) uses. Despite this, micropropagation has only been used to effectively propagate and preserve germplasm a limited number (six) of species (, , , , , ). This review on provides details of published micropropagation protocols and perspectives on their application to germplasm preservation and conservation. Such details serve as a practically useful user manual for researchers. The importance of micropropagation and its application to synthetic seed production, flowering, production of secondary metabolites, and the use of molecular markers to detect somaclonal variation , are also highlighted.
