Project description:Banana is an important tropical fruit with high value. One main specie (cultivar Cavendish) is susceptible to low temperature, another close relative specie (Dajiao), considerably higher cold tolerance than Cavendish. Our previous global proteomics results suggested that some membrane proteins be likely involved in cold tolerance of Dajiao via antioxidation mechanism. To further investigate early cold stress response of Dajiao, we applied comparative membrane proteomics analysis for both cold-sensitive Cavendish and cold-tolerant Dajiao subjected to 10 °C for 0, 3 and 6 h.

Project description:Cold-sensitive Cavendish Banana and relatively cold-tolerant Dajiao (Musa spp.) comprise an important part of diets for millions of people around the globe. Low temperature is one of the key environment stresses which greatly affect the global banana production. However, little is known about the changes of global protein phosphorylation in Musa spp. and their regulatory roles in response to cold stress. In this study, we employed a TMT6-plex quantitative analysis to conduct a global phosphoproteome profiling between Cavendish Banana and Dajiao subject to the cold stress for 0 hour and 3 hour. A total of 679 phosphopeptides containing 772 distinct phosphorylated sites from 529 phosphoproteins were identified in Cavendish Banana, 180 phosphorylation sites (belonging to 147 phosphoproteins) were differentially changed after 3 h cold stress. While in Dajiao 241 phosphopeptides with 271 individual phosphosites from 207 phosphoproteins were confidently identified, and 83 phosphorylation sites from 63 phosphoproteins were differentially changed under 3 h cold stress. Bioinformatic analysis of protein interaction network indicated that Mitogen-activated protein kinase kinase 2 (MKK2) was located in the center of the MAPK signaling network along with 7 other members whose phosphorylated site abundances were remarkably differentiated between Cavendish Banana and Dajiao in response to cold stress. Western blotting of MKK2 protein and its T31 phosphorylated site showed the increased expression of MKK2 in the time course of cold stress, with no detectable T31 phosphorylation in Cavendish Banana. On the contrary, the decreased MKK2 expression with increased T31 phosphorylation was consistently observed in Dajiao. These results suggest that the MKK2 interaction network in Dajiao, along with other cold-specific phosphoproteins found in this study, appears to play an important role in the molecular mechanisms of Dajiao being high tolerance to cold stress. The results also provide new evidence that cellular MKK2 phosphorylation as a signaling pathway plays an important role in abiotic stress tolerance that serves as a universal plant cold tolerance mechanism. To the best of our knowledge, this is the first report of MKK2 network involved in the regulatory of the Musa spp. response to cold stress.

Project description:We report the high-throughput profiling of miRNAs in banana. By deep sequencing and computational and molecular analyses, we identify 113 known and 26 banana-specific miRNAs and we characterize their expression pattern under cold and heat stress. We find that 42 banana miRNAs are temperature-responsive. By degradome sequencing, we identify 60 targets for known miRNAs and half of these targets are regulated by 15 temperature-responsive miRNAs. The correlative expression patterns between several miRNAs and their target genes are further validated via qRT-PCR. Our results provide a foundation for understanding the miRNA-dependent temperature stress response in banana and the characterized correlations between miRNAs and their responses to cold or heat stress could serve as markers in the breeding programs or tools for biotechnological approaches for improving temperature stress tolerance of banana.

Project description:Cold stress greatly affects plant growth and crop yield. To identify novel genes and possible mechanisms involved in chilling tolerance responses in rice seedlings, RNA sequencing (RNA-seq) technology was used for genome-wide gene expression profiling analysis to compare three cold-tolerant genotypes and one cold-sensitive genotype under both normal temperature and cold stress treatments.
