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:Winter season with reduced day length (photoperiod); led to the growth cessation, dormancy induction and cold acclimation in woody perennial plants. To develop an understanding of the photoperiod signal transduction in Vitis riparia; shoot tip transcriptome profiling was performed under differential photoperiod treatments (long (LD, 15h) and short day (SD, 13h)) for 7 or 21 days after shoots reached 10 nodes (LD7, SD7, LD21 or SD21).

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:BACKGROUND: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 long vs. short photoperiod. RESULTS:A total of 164 known miRNAs derived from 68 families and 203 novel miRNAs from 182 families were identified. Their 4611 targets were predicted using psRobot and TargetFinder, amongst which 349 were validated by degradome sequencing. Fourteen targets of six miRNAs were differentially expressed between the treatments. A total of eight known and 16 novel miRNAs were affected by temperature and photoperiod. Functional annotations revealed that "Plant hormone signal transduction" pathway was significantly over-represented in the miRNA targets. The miR156/157/SBP-Boxes and novel-mir153/ethylene-responsive transcription factor/senescence-related protein/aminotransferase/acyl-CoA thioesterase are the two most credible miRNA/targets combinations modulating the plant's responsive processes to the temperature-photoperiod changes. Moreover, the newly evolved, cucumber-specific novel miRNA (novel-mir153) was found to target 2087 mRNAs by prediction and has 232 targets proven by degradome analysis, accounting for 45.26-58.88% of the total miRNA targets in this plant. This is the largest sum of genes targeted by a single miRNA to the best of our knowledge. CONCLUSIONS:These results contribute to a better understanding of the miRNAs mediating plant adaptation to combinations of temperature and photoperiod and sheds light on the recent evolution of new miRNAs in cucumber.

Project description:To begin understanding transduction of the photoperiod signal, Vitis riparia Michx. (PI588259) grapevines that had grown for 35 days in long photoperiod (long day, LD, 15h) were subjected to either continued LD or a short photoperiod (short day, SD, 13h) treatment. Shoot tips (4-node shoot terminals) were collected from each treatment at 7 and 28 days of LD and SD for proteomic analysis via two-dimensional (2D) gel electrophoresis. The peptides were identified using MALDI-TOF_TOF mass spectrometer after trypsin digestion. A master gel was made and mapped with all p roteins from both photoperiod treatments. The proteins were identified by matching the peptide sequences against the 12X Vitis vinifera grape genome in NCBI. This study was funded in part by NSF grant DBI064755 and the South Dakota Agriculture Experiment Station.

Project description:In order to find out the genes involved in the heat shock response of cucumber, the seedlings of '9930', a North China type cucumber variety, were treated with high temperature at 42℃, and the leaves of the seedlings were taken after 0, 3 and 6 hours of treatment for transcriptome sequencing to analyze the differential expression genes of cucumber in response to high temperature stress. The results showed that compared with the control (heat treatment at 0h), there were 6 082 genes differentially expressed after heat treatment for 3 h and 6 h, of which 3245 were up-regulated and 2 388 were down-regulated. The results of enrichment analysis of GO and KEGG showed that these differentially expressed genes were mainly involved in metabolic pathway and protein synthesis pathway. Among the differentially expressed genes, there are many Hsp family genes, including Hsp20, HSP70 and Hsp90, which are up-regulated by heat stress, indicating that these genes may play a positive regulatory role in heat shock response of cucumber. In addition, many transcription factors, including AP2, MYB, WRKY, bHLH and HSF, were also induced by heat.

Project description:The timing of reproductive development determines spike architecture and thus yield in temperate grasses such as barley (Hordeum vulgare L.). Reproductive development in barley is controlled by the photoperiod response gene Ppd-H1 which accelerates flowering time under long-day (LD) conditions. A natural mutation in Ppd-H1 prevalent in spring barley causes a reduced photoperiod response, and thus, late flowering under LD. However, it is not very well understood how LD and Ppd-H1 control pre-anthesis development, and thus spike architecture and yield in barley. We performed a detailed morphological analysis of the pre-anthesis development in the spring barley cultivar Scarlett and its wild barley derived introgression line S42-IL107, carrying the photoperiod responsive Ppd-H1 allele. Characterization of shoot apex development in these genotypes indicated that floral transition and initiation of floral primordia occurred under LD (16h light/ 8h dark) and short day (SD, 8h light/ 16h dark) conditions, while inflorescence and seed development strictly required LDs. Additionally, a fast photoperiod response in the presence of the dominant Ppd-H1 allele promoted floret fertility under LDs. To characterize the effects of the photoperiod and allelic variation at Ppd-H1 on gene expression during pre-anthesis development we performed RNA sequencing of leaves and developing main shoot apices during the vegetative phase and early stages of inflorescence development in Scarlett and S42-IL107 grown under SD and LD conditions. Main shoot apices of both genotypes were sampled at defined developmental stages, i.e. Waddington stage W0.5, W1.0, W2.0 and W3.5, respectively. Leaf samples were harvested from plants before (W1.0) and after floral transition (W2.0). We identified genes that were specifically regulated at floral transition independent of day-length and Ppd-H1 and thus may serve as markers for the staging of floral transition. Furthermore, we identified transcripts differentially expressed between photoperiods and between genotypes in leaves and in shoot apices. This set of transcripts might act as candidates downstream of Ppd-H1 and are correlated with the promotion of shoot apex development and higher floret fertility under LD and in the presence of the photoperiod responsive Ppd-H1 allele.

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.
