Embryo rescue is a term primarily used in botany and agriculture, which refers to the process of preventing the loss or death of embryos. In genetic engineering, it is often viewed as an essential tool for the genetic improvement of crops. There are several synonyms for the term embryo rescue that are equally relevant, including embryo propagation, embryo culture, and embryo preservation. All these synonyms imply the same concept of rescuing the developing embryo to ensure its survival and possibly to enhance its growth potential. These techniques are often used in crop production, plant breeding, and animal husbandry to produce offsprings that have higher genetic quality than their parents.
