Somatic Embryogenesis in Banana (Musa spp.)

Methods Mol Biol. 2022;2527:97-110. doi: 10.1007/978-1-0716-2485-2_8.ABSTRACTBananas (Musa ssp.) are among the world's most important crops. In terms of gross value of production, they are the fourth most important global food crop and have an important socioeconomic and ecological role. Somatic embryogenesis (SE) is a developmental process, in which somatic cells differentiate into embryos which eventually develop and regenerate into plants. SE is exploited to generate a large quantity of very high economic value, genetically identical and disease-free plantlets. In bananas, the use of shoot apexes of axillary buds to induce SE resulted an alternative for plant regeneration through embryogenic cell suspension (ECS). The protocol has been scaled up to commercial laboratories for tissue culture (biofactories) for production of planting materials. The genetic stability of regenerated plants and high yields obtained under field conditions demonstrate the feasibility of scaling up this biotechnological protocol and adapting it to commercial production of planting materials to mitigate a critical bottleneck in the value chain of this important crop.PMID:35951186 | DOI:10.1007/978-1-0716-2485-2_8
