Project description:By characterizing the cell wall proteomes of different sugarcane organs (leaves and stems) at two developmental stages (young vs mature/apical vs basal), it was possible to address unique characteristics in each of them. Four-month-old leaves showed a higher proportion of oxido-reductases and proteins related to lipid metabolism (LM), besides a lower proportion of proteins acting on polysaccharides, in comparison to four-month-old internodes. It was possible to note that sugarcane leaves and young stems have the highest LM rate than all species, which was assumed to be linked to cuticle formation. The data generated enriched the number of cell wall proteins (CWPs) identified in sugarcane, reaching 277. To our knowledge, sugarcane has now the second higher coverage of monocot CWP in plants

Project description:Drought is considered the major abiotic stress limiting crop productivity. This study sought to identify proteins involved in the drought response in sugarcane stems submitted to drought stress. The integration of nuclei enrichment sample preparation with the shotgun proteomic approach (nLC-MS/MS) resulted in great coverage of the sugarcane stem proteome with 5,381 protein groups identified (1% FDR). A total of 1,204 differentially accumulated proteins (DAPs) were detected in response to drought, among which 586 showed increased abundance and 618 decreased abundance.

Project description:Background: Sugarcane is an important sugar and energy crop largely used for bioethanol production in the world. The development of sugarcane cultivars with high sucrose content and yield is one of the biggest challenges of breeding programs nowadays. To identify genes networks that underlie sucrose content and yield, we used a custom designed oligonucleotide array with 21,901 different probes to study the transcriptome from breeding populations of sugarcane contrasting to sucrose content and genotypes contrasting to photosynthesis rate. Results: Physiological and biochemical data reveals that the transcriptome profiles described here showed a close relationship between sucrose content and stem development. A total of 2135 genes were differentially expressed in at least one experimental hybridization. We identified genes related to carbohydrate metabolism, cell wall metabolism and signal transduction. The same oligoarrays was used to detect transcription in both sense and antisense orientation. The enriched functional category from antisense expressed genes reveals light harvesting and circadian clock as the two top categories that can be related to photosynthesis and yield in sugarcane. Conclusions: Knowledge on the mechanisms underlying carbon partitioning and its relationship with sucrose accumulation in sugarcane stems would help defines routes to increase yield. Our findings showed for instance that sucrose accumulation and yield in sugarcane may be regulated by hormone signaling pathways, light harvesting and circadian clock genes. Analysis of the expression data and gene category enrichment provided an insight into signaling pathways and transcriptional control contrasting in high brix and low brix plants as well as differing photosynthesis rates and yield.

Project description:Background and aims The endophytic diazotrophic strain CBAmC of Nitrospirillum amazonense has been reported as a plant growth promoter of sugarcane variety RB867515 when grown under field conditions. The present work aimed to assess the influence of apoplast fluid from RB867515 on the transcriptomic and proteomic profiles of CBAmC cultured in vitro. Methods RNA-Seq in Ion Proton™ and ESI-LC-MS/MS peptide analysis were used to evaluate the transcriptomic and proteomic profiles, respectively, of CBAmC exposed for 2 h to the sugarcane apoplast fluid. Results The bacterial transcriptomic and proteomic profiles were well correlated. The overall response of CBAmC to the apoplast fluid included overexpression of defense systems against reactive oxygen species (ROS) and osmotic stress, RND efflux pumps for toxic compounds, Sec and Tat secretory systems, and assimilative metabolism of iron. In contrast, active transporters of organic compounds, chemotaxis system and flagellum structure were underexpressed. Conclusions The bacterial metabolic pathways / functions activated in response to the sugarcane apoplast fluid are most likely related to its adaptation to the peculiar characteristics of the fluid. The activation of some of those functions could be determinant for its adaptation to the sugarcane apoplastic niche, and perhaps be involved in the previously observed effect of promoting plant growth.
