Project description:RNA Seq was extracted from cucumber leaves after 7 days of bacteria inoculated in shoot and salt stress treatment. There were four treatment in this study, : ‘CK’ stands for seedlings under 0 mM NaCl without BC56 inoculation; ‘BC56’ refers to seedlings under 0 mM NaCl with BC56 inoculation; ‘Salt’ means seedlings under 100 mM NaCl without BC56 inoculation; ‘BC56+Salt’ indicates seedlings under 100 mM NaCl with BC56 inoculation.GO was used to assign putative functions to all identified DEGs into three principal categories, namely cellular component, molecular function, and biological process. An analysis of the GO terms suggested that ‘nucleus’, ‘plasma membrane’, and ‘integral component of membrane’ were the most dominant terms in the cellular component. While ‘biological process’, ‘regulation of transcription, DNA -templated’ and ‘transcription, DNA-templated’ were the most abundant terms in the biological process. In addition ‘molecular function’, ‘protein binding’ and ‘DNA-binding transcription factor activity’ were the major terms in the molecular function category. KEGG pathway analysis of DEGs in different comparison group suggested that in the BC56 vs CK comparison group DEGs were mainly enriched in four pathways which are ‘photosynthesis - antenna proteins’, ‘phenylpropanoid biosynthesis’, ‘metabolic pathways’ and ‘MAPK signaling pathway – plant’. In the BC56 vs CK comparison group DEGs were mainly enriched in seven pathways which are ‘phenylpropanoid biosynthesis’, ‘plant hormone signal transduction’, ‘biosynthesis of secondary metabolites’, ‘flavonoid biosynthesis’, ‘metabolic pathways’, ‘carotenoid biosynthesis’ and ‘stilbenoid, diarylheptanoid and gingerol biosynthesis’. In addition, compared with BC56+Salt vs CK, ‘ABC transporters’, ‘nitrogen metabolism’ and ‘phenylalanine metabolism’ is only significantly enriched in Salt vs CK.

Project description:Previous study we have reported the cucumber TEOSINTE BRANCHED1/CYCLOIDEA/PCF (TCP) family gene BRANCHED1 (CsBRC1) as a main transcription factor functions to regulate shoot branching. Here, we found CsBRC1 (CsTCP18b in this study) had a paralogous gene CsTCP18a. To investigate whether the function of CsTCP18a was same as CsTCP18b, we carried out biochemical experiments and genetic transformation. The Real-Time PCR and in situ hybridization showed that CsTCP18a displayed different expression patterns in cucumber compared with CsTCP18b. Ectopic expression of CsTCP18a in Arabidopsis tcp18 (brc1) mutants resulted in a decreased number of rosette branches and rosette leaves, whereas silencing CsTCP18a in cucumber only led to a deformed true leaf of seedling without influencing the shoot branching. RNA-seq analysis of wild-type plants and CsTCP18a-RNAi lines implicated that CsTCP18a regulated early leaf development of cucumber through affecting the transcripts of auxin and cytokinin related genes. Further studies indicated that CsTCP18a could directly interact with CsTCP10 and CsTCP18b in vitro and in vivo. Therefore, our data suggested that CsTCP18a had functional redundancy with CsTCP18b in inhibiting axillary buds outgrowth, and it could also regulate leaf development during cucumber seedling.

Project description:The cucumber is one of the most important vegetables worldwide and is used as a research model for study of phloem transport, sex determination and temperature-photoperiod physiology. The shoot apex is the most important plant tissue in which the cell fate and organ meristems have been determined. In this study, a series of whole-genome small RNA, degradome and transcriptome analyses were performed on cucumber shoot apical tissues treated with high vs. low temperature and a long vs. short photoperiod.

Project description:Salinity seriously reduces the yield and quality of crops. Silicon (Si) has been widely reported to have beneficial effects on plant growth and development under salt stress. However, the mechanism is still poorly understood. In an attempt to identify genes or gene networks that may be orchestrated to improve salt tolerance of cucumber plants, we profiled the RNA-seq transcriptomes of both control and salt-stressed cucumber leaves in the presence or absence of added Si. The comparative transcriptome analysis revealed that Si plays an important role in shaping the transcriptome of cucumber: the expression levels of >1,000 genes (differtially expressed genes, DEGs) were changed in response to Si treatment as compared with the control, and these genes were mainly involved in ion transport, hormone and signal transduction, biosynthesis and metabolic processes, stress and defense responses, and antioxidant activity. Under salt stress, many genes functionally associated with metabolic processes and responses to environmental stimuli were strongly up- or down-regulated in their expressions. Si treatment showed a tendency that induced the transcriptomic profile of salt-stressed cucumber back to that of the control with large majority of Na down-regulated DEGs and about half of Na up-regulated DEGs being adjusted back to CT levels. This study provides a novel insight into the mechanism for Si-mediated alleviation of salt stress in plants at the transcriptome level, and it suggests that Si may act as an elicitor to precondition cucumber plants and induce salt tolerance.

Project description:The experiment was made do to assess the influence of increased salt concentration on cucumber chloroplast transcription. We used 0,4M NaCl water solution and we checked its influence on plants after 0, 4, 8, 24, 48 hours. We have also measured changes in chloroplast gene expression after recovery of plants in water (48 hours of 0,4M NaCl solution treatment followed by 48 hours in clean water). Other growth conditions weren't changed comparing to those of standard plants growth in our experiments (check: versatile chamber growth protocol)

Project description:In a previous study, we found that H2S alleviates salinity stress in cucumber by maintaining the Na+/K+ balance and by regulating H2S metabolism and the oxidative stress response. However, little is known about the molecular mechanisms behind H2S-regulated salt-stress tolerance in cucumber. Here, an integrated transcriptomic and proteomic analysis based on RNA-seq and 2-DE was used to investigate the global mechanism underlying H2S-regulated salt-stress tolerance. In total, 11 761 differentially expressed genes (DEGs) and 61 differentially expressed proteins (DEPs) were identified. Analysis of the pathways associated with the DEGs showed that salt stress enriched expression of genes in primary and energy metabolism, such as photosynthesis, carbon metabolism and biosynthesis of amino acids. Application of H2S significantly decreased these DEGs but enriched DEGs related to plant-pathogen interaction, sulfur-containing metabolism, cell defense and signal transduction pathways. Notably, changes related to sulfur-containing metabolism and cell defense were also observed through proteome analysis, such as Cysteine synthase 1, Glutathione S-transferase U25-like, Protein disulfide-isomerase and Peroxidase 2. We present the first global analysis of the mechanism underlying H2S regulation of salt-stress tolerance in cucumber through tracking changes in the expression of specific proteins and genes.

Project description:Shoot branching is an important agronomic trait that directly determines plant architecture and affects crop productivity. To promote crop yield and quality, axillary branches need to be manually removed during cucumber production for fresh market and thus are undesirable. Auxin is well known as the primary signal imposing for apical dominance and acts as a repressor for branching outside of the lateral buds. The TEOSINTE BRANCHED1/CYCLOIDEA /PCF (TCP) family gene BRANCHED1 (BRC1) has been shown to be the central integrator for multiple environmental and developmental factors that functions locally to inhibit shoot branching. However, no direct link has been reported between auxin and BRC1. Here, we find that cucumber BRANCHED1 (CsBRC1) is expressed in the axillary buds and displays higher expression level in cultivated cucumber than its wild ancestor. Knockdown of CsBRC1 by RNAi leads to increased bud outgrowth and reduced auxin accumulation in buds. We further show that CsBRC1 directly binds to two auxin efflux carriers PIN-FORMED (CsPIN1b and CsPIN3) and negatively regulates their expression. Ectopic expression of CsPIN1b or CsPIN3 driven by CsBRC1 promoter results in increased shoot branching. Moreover, shade induces the expression of CsBRC1 in cultivated cucumber, but not in wild ancestor, which may be partly due to the addition of two light response elements in the CsBRC1 promoter of cultivated cucumber. Therefore, our data suggest the formation of a regulatory pathway of shade-CsBRC1-auxin transport in suppressing lateral bud outgrowth during cucumber domestication.
