Cloning Coconut via Somatic Embryogenesis: A Review of the Current Status and Future Prospects

Abstract

Coconut [Cocos nucifera L.] is often called “the tree of life” because of its many uses in the food, beverage, medicinal, and cosmetic industries. Currently, more than 50% of the palms grown throughout the world are senile and need to be replanted immediately to ensure production levels meet the present and increasing demand for coconut products. Mass replanting will not be possible using traditional propagation methods from seed. Recent studies have indicated that in vitro cloning via somatic embryogenesis is the most promising alternative for the large-scale production of new coconut palms. This paper provides a review on the status and prospects for the application of somatic embryogenesis to mass clonal propagation of coconut.

Transcriptional Regulations and Hormonal Signaling during Somatic Embryogenesis in the Coconut Tree: An Insight

“…These constraints result in more embryogenic callus production and toil to gain greater yields [34]. In the SE process, cell-to-plantlet formation is followed by various factors, such as medium composition, explant type, plant growth regulators (PGRs), heterogenous response, and acclimatization procedure [35,36]. In the last two decades, significant efforts have been made to develop and optimize propagation methods of coconut plantlets through SE [37].…”
