Overexpression of MpbHLH transcription factor, an encoding ICE1-like protein, enhances Foc TR4-resistance of Cavendish banana

• Overexpression of MpbHLH in Foc TR4-sensitive Cavendish banana showed that the transgenic lines had superior resistance to Fusarium wilt compared with wild-type (WT). Proteomic analysis phenylalanine ammonia lyase (PAL) and peroxidase (POD) were highly expressed plants. 3. Physiological experiments further revealed plants, especially their roots, high POD activity. Banana ( Musa spp . ) is an important tropical fruit economic value, however, disease a critical factor affecting sound development industry. Different cultivars exhibit degree genetic variability for wilt. Compared spp. AAA group), Dajiao ABB group) has provides excellent test material isolation characterization genes. In this study, candidate gene, (basic helix-loop-helix), encoding ICE1-like protein transcription (TF), was cloned characterized. Real-time quantitative PCR (qPCR) results transcript levels strongly induced under cold treatment, salt, dehydration. Taken together, overexpression may extensively activate stress-related particular, activity increases by enhancing reactive oxygen species (ROS) scavenging system plant.
