| description | Flooding caused or exacerbated by climate change has threatened plant growth and
food production worldwide. The lack of knowledge on how crops respond and adapt to flooding
stress imposes a major barrier to enhancing their productivity. Hence, understanding the floodingresponsive
mechanisms of crops is indispensable for developing new flooding-tolerant varieties.
Here, we examined the banana (Musa acuminata cv. Berangan) responses to soil waterlogging for
1, 3, 5, 7, 14, and 24 days. After waterlogging stress, banana root samples were analyzed for their
molecular and biochemical changes. We found that waterlogging treatment induced the formation
of adventitious roots and aerenchyma with conspicuous gas spaces. In addition, the antioxidant
activities, hydrogen peroxide, and malondialdehyde contents of the waterlogged bananas increased in
response to waterlogging stress. To assess the initial response of bananas toward waterlogging stress,
we analyzed the transcriptome changes of banana roots. A total of 3508 unigenes were differentially
expressed under 1-day waterlogging conditions. These unigenes comprise abiotic stress-related
transcription factors, such as ethylene response factors, basic helix-loop-helix, myeloblastosis, plant
signal transduction, and carbohydrate metabolisms. The findings of the study provide insight into
the complex molecular events of bananas in response to waterlogging stress, which could later help
develop waterlogging resilient crops for the future climate. |
