Transcriptional profiling and genes involved in acquired thermotolerance in Banana: a non-model crop
Abstract Banana is a non- model crop plant, and one of the most important crops in the tropics and sub tropics. Heat stress is the major abiotic stress affecting banana crop production because of its long growth period and is likely to become a threat due to global warming. To understand an acquired...

| Sumario: | Abstract Banana is a non- model crop plant, and one of the most important crops in the tropics and sub tropics. Heat stress is the major abiotic stress affecting banana crop production because of its long growth period and is likely to become a threat due to global warming. To understand an acquired thermotolerance phenomenon at the molecular level, the RNA-seq approach was employed by adapting TIR method. A total of 136.38 million high quality reads were assembled. Differentially expressed genes under induction (I) was 3936, I + L was 2268 and lethal stress was 907 compared to control. Gene ontology and DGE analysis showed that genes related to heat shock factors, heat shock proteins, stress associated proteins, ROS scavenging, fatty acid metabolism, protein modification were significantly up regulated during induction, thus preparing the organism or tissue at molecular and cellular level for acquired thermotolerance. KEGG pathway analysis revealed the significant enrichment of pathways involved in protein processing, MAPK signaling and HSPs which indicates that these processes are conserved and involved in thermo tolerance. Thus, this study provides insights into the acquired thermotolerance phenomena in plants especially banana. |
