Abstract
The present disclosure provides novel methods and compositions for the maturation and regeneration of plantlets from microspore-derived embryos. The compositions provided include a liquid maturation composition comprising a first plant hormone and about 430 mM to about 880 mM of a monosaccharide solute, a disaccharide solute, or a polysaccharide solute. The methods provided include the steps of contacting a microspore-derived embryo with a liquid maturation medium for a time period sufficient to produce a matured microspore-derived embryo, transferring the matured microspore-derived embryo to a substrate, and regenerating the plantlet from the matured microspore-derived embryo.
