Cultivar-specific markers, mutations, and chimerisim of Cavendish banana somaclonal variants resistant to Fusarium oxysporum f. sp. cubense tropical race 4.

ABSTRACT:

Background

The selection of tissue culture-derived somaclonal variants of Giant Cavendish banana (Musa spp., Cavendish sub-group AAA) by the Taiwan Banana Research Institute (TBRI) has resulted in several cultivars resistant to Fusarium oxysporum f. sp. cubense tropical race 4 (Foc TR4), a destructive fungus threatening global banana production. However, the mutations in these somaclonal variants have not yet been determined. We performed an RNA-sequencing (RNA-seq) analysis of three TBRI Foc TR4-resistant cultivars: 'Tai-Chiao No. 5' (TC5), 'Tai-Chiao No. 7' (TC7), and 'Formosana' (FM), as well as their susceptible progenitor 'Pei-Chiao' (PC), to investigate the sequence variations among them and develop cultivar-specific markers.
