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.

Project description:Decrease in agricultural productivity in successive cuttings of sugarcane plants has been related to several extrinsic and intrinsic factors, even though no studies have been recently conducted to assess the physiological potential of sett roots in successive cuts in sugarcane culture. Proteomic studies on sugarcane sett roots at different cut stages are unknown. The UPLC-ESI-TOF-MS system and bioinformatics tools were used to identify proteins of sett roots in the first and fifth cuts of sugarcane cultivar RB966928 in the sprouting stage. The differences in proteome of sett roots from sugarcane cv. RB966928 in the first and fifth cut detected in current study support the hypothesis that the proteome of sett roots may change after successive cuts in sugarcane culture. A reduction in the number of proteins has been observed in the roots of the fifth cut, while 34% of proteins, identified exclusively in the first cut, were absent in the fifth one. Proteome analysis of sett roots in the first and fifth cut showed that the changes after successive cuts are not only quantitative, but mainly qualitative. The detailed list of proteins identified in the first cut but absent in the fifth cut reported in the present study is relevant since it opens a perspective for the lines of research that employ biotic or abiotic elicitors to induce gene expression for essential proteins absents in sett roots of the fifth cut, increasing the agricultural productivity and longevity of cane fields.

Project description:Sugarcane is an important crop worldwide for sugar production and increasingly, as a renewable energy source. Modern cultivars have polyploid, large complex genomes, with highly unequal contributions from ancestral genomes. Long Terminal Repeat retrotransposons (LTR-RTs) are the single largest components of most plant genomes and can substantially impact the genome in many ways. It is therefore crucial to understand their contribution to the genome and transcriptome, however a detailed study of LTR-RTs in sugarcane has not been previously carried out. Sixty complete LTR-RT elements were classified into 35 families within four Copia and three Gypsy lineages. Structurally, within lineages elements were similar, between lineages there were large size differences. Four distinct patterns were observed in sRNA mapping, the most unusual of which was that of Ale1, with very large numbers of 24nt sRNAs in the coding region. The results presented support the conclusion that distinct small RNA-regulated pathways in sugarcane target the lineages of LTR-RT elements. Individual LTR-RT sugarcane families have distinct structures, and transcriptional and regulatory signatures. Our results indicate that in sugarcane individual LTR-RT families have distinct behaviors and can potentially impact the genome in diverse ways. For instance, these transposable elements may affect nearby genes by generating a diverse set of small RNA's that trigger gene silencing mechanisms. There is also some evidence that ancestral genomes contribute significantly different element numbers from particular LTR-RT lineages to the modern sugarcane cultivar genome. Examination of small RNA populations in the sugarcane leaves that show matches against sugarcane LTR-RTs.

Project description:Sugarcane is a very efficient crop to produce ethanol. In recent years, extensive efforts have been made in order to increase sugarcane yields. To reach this goal, molecular biology tools have been used comprehensively, identifying genes, pathways and genetic polymorphisms. However, some important molecular components, like microRNAs, have not been deeply investigated. MicroRNAs are an important class of endogenous small, noncoding RNAs that regulate gene expression at the post-transcription level and play fundamental roles in diverse aspects of animal and plant biology. Plant genomes harbor numerous miRNA genes that regulate many protein-coding genes to influence key processes ranging from development, metabolism, and responses to abiotic and biotic stresses. There is wide range of pests and diseases that affect sugarcane, yet the mechanisms that regulate pathogen interactions with sugarcane have not been thoroughly investigated. To gain knowledge on the physiological responses to pathogens mediated by microRNAs in sugarcane, we screened the transcriptoma of sugarcane plants infected with Acidovorax avenae subsp avenae, the causal agent of red stripe disease in sugarcane, and detected several microRNAs modulated in the presence of the pathogen. Furthermore, we validated with qPCR a number of microRNA expression patterns observed by bioinformatics analysis. In addition, we observed high expression levels of several star microRNAs, in numbers larger than the mature microRNAs in some cases. Interestingly, sof-miR408 was consistently down-regulated in the presence of several pathogens, but not in the presence beneficial microbes. This result indicates that the sugarcane senses pathogenic or beneficial microorganisms differentially and triggers specific epigenetic regulatory mechanisms accordingly Screenning of sRNA transcriptome of sugarcane plants infected with Acidovorax avenae subsp avenae after seven days

Project description:We performed cell wall proteins (CWPs) extraction and analysis from sugarcane 7-month-old young and mature leaves and basal and apical internodes in order to point the differences regarding the cell wall proteome composition in these specific organs and diverse developmental stages. We used two different extraction methods for leaves CWPs: destructive and non-destructive. For internodes, only the non-destructive technique was used. The collection of CWPs was identified through LC-MS/MS analyses. Altogether, 110 sugarcane CWPs were identified and classified into eight functional categories. Sugarcane has one of the highest coverage of CWPs identified by mass spectrometry, reaching 283.
