What is it about?
The objective of this work is to induce tolerance to desiccation in somatic embryos of sugarcane encapsulated in alginate beads using abscisic acid (ABA) and jasmonic acid (JA).

Why is it important?
The experiments described in the present paper show that ABA has a positive effect on induction of desiccation tolerance of encapsulated somatic embryos of sugarcane. When ABA is combined with sucrose as a protectant agent to desiccation,results are superior to that of ABA alone. On the other hand, JA was not effective.The results show that both ABA and JA have different effects on the biochemical content and survival of the embryos. The increased synthesis of Gallic acid induced by ABA and the ABA-JA combination and 4-methyl catechol induction by JA in induction medium, may suggest an involvement of these compounds in the process leading to stress tolerance of sugarcane somatic embryos.
Perspectives
The prospect of using somatic embryos as artificial seeds may revolutionise aspects of plant propagation, germplasm storage and perhaps hybrid seed production.
