Abstract
The genus Musa spp. contains commercially important fleshy fruit producing plants including plantains and bananas with a strong potential of providing food security and source of revenue to farmers. Occasionally, plantlets are often not available to fulfill the supply demand of farmers particularly in Caribbean region. Concerns with the quality of vegetative tissues along with the possibility of the transmission of phytopathogens makes availability of plantlets limited to farm-ers. Micropropagation of plantains offers an alternative to producing large number of in-vitro plantlets. However, conventional methods of micropropagation techniques require high produc-tion costs and are labor-intensive. Recently, Temporary Immersion Bioreactor (TIB) has emerged as an alternative to conventional micropropagation methods. Our work utilized SEM (Scanning Electron Microscope), molecular and biochemical tools (qRT-PCR and ICP-OES) to characterize and compare the morphological, elemental composition, and photosynthetic gene expression of plantains cultured on TIB. Additionally, morphological features of growth and propagation rates were analyzed for comparing outputs obtained from temporary immersion bioreactor with conventional micropropagation (CM) techniques. Results showed higher growth and multiplication rates for plantlets cultivated in TIB. Gene expression analysis of selected photosynthetic genes demonstrated high transcript abundance of phosphoenol pyruvate carboxylase (PEPC) in plantain tissues obtained by TIB. Elemental composition analysis showed higher content of iron in plantains grown in TIB suggesting a potential correlation with PEPC expression. These results demonstrate the potential of TIB to be an efficient method to produce healthy in-vitro plantains.
