Project description:Transcriptional profiling of sugarcane leaf (+1) was collected from drought-prone areas at 42 and 117 days after the last rainfall when plants were 6- and 9-month-old, respectively. Sample hybridization (non-irrigated treatment against irrigated control) was performed to monitor gene expression in a two-color Agilent custom microarray. Our goal was to investigate the effect of mild and severe water stress on the transcriptomes of drought-sensitive (IACSP97-7065) and -tolerant (IACSP94-2094) sugarcane genotypes.

Project description:In order to increase our understanding on the epigenetic regulation in response to abiotic stresses in plants, sRNA regulation in sugarcane plants submitted to drought stress was analyzed. Deep sequencing analysis was carried out to identify the sRNA regulated in leaves and roots of sugarcane cultivars with different drought sensitivities. An enrichment of 22-nt sRNA species was observed in leaf libraries. The pool of sRNA selected allowed the analysis of different sRNA classes (miRNA and siRNA). Twenty eight and 36 families of conserved miRNA were identified in leaf and root libraries, respectively. Dynamic regulation of miRNA was observed and the expression profile of eight miRNA was verified in leaf samples by stem-loop qRT-PCR assay. Altered miRNA regulation was correlated with changes in mRNA levels of specific targets. 22-nt miRNA triggered siRNA-candidates production by cleavage of their targets in response to drought stress. Some genes of sRNA biogenesis were down-regulated in tolerant genotypes and up-regulated in sensitive in response to drought stress. Our analysis contributes to increase the knowledge on the roles of sRNA in epigenetic-regulatory pathways in sugarcane submitted to drought stress.

Project description:Proteomics of organelle and cytoplasmic enriched samples from Sorghum bicolor RTx430 (pre-flowering drought tolerant) and RTx642 (pre-flowering drought sensitive) before and during drought. 3 biological replicates, except BTx642 drought samples, which had 2 biological replicates due to limited sample. Identified multiple protein-level responses in both genotypes, demonstrated that these responses are consistent with the literature, as well as identified multiple RTx430-specific changes that suggest novel drought-tolerance strategies unique to RTx430. Sorghum leaves (both genotypes, +/- drought) were separated into cytosolic and organelle fractions, then digested with trypsin, and analyzed by LC-MS/MS. Data was searched using MaxQuant's Andromeda and a UniProt database. Data was then evaluated for missingness, normalized, and missing values imputed using Bioconductor R package DEP (Zhang et al. 2018).

Project description:Background: Drought stress is the major environmental stress that affects plant growth and productivity. It triggers in plants a wide range of responses detectable at different scales: molecular, biochemical and physiological levels. At the molecular level the response to drought stress results in the differential expression of several metabolic pathways. For this reason, explore the subtle differences existing in gene expression of drought sensitive and drought tolerant genotypes allows to identify drought-related genes that could be used for selection of drought tolerance traits. Genome-wide RNA-Seq technology was used to compare the drought response of two sorghum genotypes characterized by contrasting water use efficiency. Results: the physiological measurements carried out confirmed the drought sensitivity of IS20351 and the drought tolerance of IS22330 previously studied. The expression of drought-related genes was more abundant in the sensitive genotype IS20351 compared to the tolerant IS22330. The Gene Ontology enrichment highlighted a massive increase in transcript abundance in “response to stress” and “abiotic stimulus”, “oxidation-reduction reaction” in the sensitive genotype IS20351 under drought stress. “Antioxidant” and “secondary metabolism”, “photosynthesis and carbon fixation process”, “lipids” and “carbon metabolism” were the pathways most affected by drought in the sensitive genotype IS20351. The sensitive genotype IS20351 showed under well-watered conditions a lower constitutive expression level of “secondary metabolic process” (GO:0019748) and “glutathione transferase activity” (GO:000004364). Conclusions: RNA-Seq analysis revealed to be a very useful tool to explore differences between sensitive and tolerant sorghum genotypes. The transcriptomic results supported all the physiological measurements and were crucial to clarify the tolerance of the two genotypes studied. The connection between the differential gene expression and the physiological response to drought states unequivocally the drought tolerance of the genotype IS22330 and the strategy adopted to cope with drought stress.

Project description:Sugarcane established industrial crop providing sugar, ethanol and biomass-derived electricity around the world. Cane sugar content is an important, breeding target, but its improvement remains very slow in many breeding programmes. Biotechnology strategies to improve sucrose accumulation made little progress at crop level, mainly due to the limited understanding of its regulation. MiRNAs regulate many metabolic processes in plants. However, their roles and target genes associated with sugarcane sucrose accumulation remains unknown. Here, we conducted high-throughput sequencing of transcriptome, small RNAs and degradome of leaves and stem of two sugarcane genotypes with contrasting sucrose content from the early to late stages of sucrose accumulation stages, which provided more insights into miRNA-associated gene regulation during sucrose accumulation. Transcriptome analysis identified 18,722 differentially expressed genes (DEGs) between both genotypes during sucrose accumulation. The major DEGs identified were involved in starch and sucrose metabolism, and photosynthesis etc. miRNA sequencing identified 563 known and 281 novel miRNAs from both genotypes during sucrose accumulation. Of these, 311 miRNAs were differentially expressed.752 targets of 368 miRNAs (609 targets for 260 known miRNAs and 168 targets for 108 novel miRNAs) were identified by degradom sequencing.Several known and novel miRNAs and their target genes associated with sugar metabolism, sugar transport and sucrose storage were identified in this study.This new insight into the complex network of sucrose accumulation in sugarcane will help identify candidate targets for sucrose improvement in sugarcane through molecular means.

Project description:Drought stress is a major problem around the world and although progress in understanding how vegetable crops and model plants adapt to drought have been made, there is still little information about how fruit crops deal with moderate drought stress. In this study, we investigated the response of two apple genotypes: a drought-sensitive genotype (M26) and a drought-tolerant genotype (MBB). Our results of the morphology, physiology and biochemistry under moderate drought stress, indicated that relative water content (RWC) and leaf area (LA) were not significant changes in two genotypes. However, it had larger leaf mass per area (LMA), and accumulated higher free proline (CFP), soluble sugars (CSS) and malonaldehyde (MDA) in the leaves. Thus, it appears that the MBB genotype could produce more osmosis-regulating substances. Phosphoproteomic was analyzed from leaves of both genotypes under moderate drought stress using the isobaric tags for relative and absolute quantification (iTRAQ) technology. A total of 595 unique phosphopeptides, 682 phosphorylated sites and 446 phosphoproteins were quantitatively analyzed in the two genotypes. Motif analyses of the phosphorylation sites showed that six motifs including [PxsP], [sP], [sD], [Rxxs], [sxP] and [sxs] were enriched. We identified 12 and 48 PLSC phosphoproteins in M26 and MBB, respectively. Among these, 9 PLSC phosphoproteins were common to both genotypes, perhaps indicating a partial overlaps of the mechanisms to moderate drought stress. Gene ontology analyses revealed that the PLSC phosphoproteins present a unique combination of metabolism, transcription, translation and protein processing, suggesting that the response in apple to moderate drought stress encompasses a new homeostasis of major cellular processes. The basic trend was an increase in protein abundance related to drought and organic substance upon moderate drought stress between two genotypes. These increases were higher in the drought-tolerant genotype (MBB) than in the drought-sensitive genotype (M26). The 23 differentially expressed mRNA encoding phosphoproteins were analysis by quantitative real-time PCR (qRT-PCR). Our study is the first to address the phosphoproteome of a major fruit crop, apple rootstocks, in response to moderate drought stress, and provide insights into the molecular regulation mechanisms of apple rootstock under moderate drought stress.
