Project description:We used Bio-Rad laboratories, lnc. PCR assay panel to analyze expression levels of MAPK genes under various stress conditions and plant hormone treatments. Cucumber plants of the ‘Jinyan No.4’ cultivar were reared in growth chambers at 28 ± 1 °C with a photoperiod of 16 h light/8 h dark and light intensity of 400 μmol m−2 s−1. Three-week-old seedlings were used for all abiotic and biotic treatments. For heat or cold treatment, the seedlings were subjected to 35 ± 1 °C or 4 ± 1 °C conditions, respectively. The samples for RNA extraction were collected at 0, 1, 2, 4, and 8 h after treatment. For dehydration treatment, the leaves of plants were sampled at 0, 2, 4, and 6 d after watering stopped. For disease treatment, Pseudoperonospora cubensis (P.cubensis) was used to infect the seedlings, and leaves were collected at 0, 1, 2, and 3 d after infection. For hormone treatments, the seedling leaves were sprayed with 100 mM methyl jasmonate (meJA) or 100 mM abscisic acid (ABA) and then sampled at 0, 1, 2, 4, and 8 h intervals. The experiment was designed to examine the transcription patterns of 58 MAPK cascade genes in cucumber in response to three different abiotic stresses (cold, heat, and drought), one biotic stress (Pseudoperonospora cubensis) and two (MeJA and ABA) plant hormone treatments.

Project description:There are 16 organ samples (dry seeds, 24H imbibed seeds, 48H imbibed seeds, juvenile rosette, adult rosette, senescence leaves, cauline leaves, stems, young buds, mature flower buds, flowers, young siliques, mature siliques and old siliques) with triplicates. There are 17 samples of different environmental samples (0 h white, 1 h white, 6 h white, 24 h white, dark, blue, far-red and red lights, control, cold 2h, cold 6h, hot 2h, hot 6h, NaCl 2h, NaCl 6h, dry 2h and dry 6h) with triplicates. For 12 organs, three lines of plants were grown in soil under the long-day conditions of 16 hours light at 22℃. Samples were collected from each of juvenile rosette leaves, adult rosette leaves, cauline leaves, stems, young flower buds (sepals were closed and petals are not visible), mature flower buds (petals are visible), flowers, young siliques filled with white seeds, mature siliques filled with green seeds, old yellowing siliques (2-month-old) and senescence rosettes. Root tissues were collected from 2-week-old plants growing on 1% agar plates containing Murashige and Skoog (MS). Callus were collected from cultured CIM (callus induction medium) containing B5 medium supplemented with 20 g liter–1 glucose, 0.5 mg liter–1 2,4-D, and 0.1 mg liter–1 kinetin. Dry seed was defined to be after-ripened seeds for 4 weeks. Imbibed seeds are collected from seeds imbibed on the moistened paper for 24 and 48 hours under the continuous light at 22℃. In light irradiations, wild type (WT) seeds were plated on MS plates. For the time course experiment of white light, the plates were placed at 4°C in darkness for at least 2 days prior to receiving 6 h red light irradiation to synchronize germination. Then, plates were placed in the dark for 3 days and then exposed to white fluorescent light (100 μmol m–2 s–1) for 1, 6 and 24 h. For monochromatic light experiment, WT seedlings were grown in continuous red light, blue light, far-red light, or darkness for 6 days after red light irradiation. The light intensity used was 0.17 μmol m–2 s–1 for red light, 1.16 μmol m–2 s–1 for blue light and 0.53 μmol m–2 s–1 for far-red light. All abiotic stress samplings were collected from plants grown for 2 weeks on MS plates under 2 and 6 hours of abiotic stress conditions at the continuous light at 22℃. For drought stress treatment, plants were transferred and dehydrated onto the dried filter paper in the covered plastic dishes. For heat and cold stress treatments, the covered plastic dishes with plants were transferred directly from 22 to 37 and 2℃ respectively. For salinity stress treatment, plants were transferred onto the filter paper moistened with MS plates including 200mM NaCl.

Project description:Lateral organ development is important for cucumber yield, while the molecular mechanism controlling leaf and floral organ development in cucumber remain elusive. In this report, a novel EMS-mutaginized mutant, round leaf (rl) was distinguished with remarkable round leaf shape, abnormal floral organ and inhibited tendril outgrowth in early development phase. Moreover, the ovule organogenesis disrupted completely in parthenocarpy fruit of rl. MutMap+ analysis revealed that RL encodes a protein kinase PINOID (CsPID, Csa1G537400). A non-synoymous SNP in the second exon of CsPID resulted in an amino-acid substitution from Arg in the wild type to Lys in the rl mutant. CsPID was down-regulated in rl mutant and preferentially expressed in young leaf, and flower buds. IAA quantification showed that rl plants exhibited a lower IAA content than wild type in ovary and blade edge. IAA immunolocalization results confirmed the IAA content alteration in rl plants. Transcriptome profile analysis further suggested IAA biosynthesis, polar transport and signal transduction genes participated in the leaf and floral development process by CsPID. Biochemical analyses showed that CsPID may regulate leaf shape by interacting with CsREV. In conclusion, this study revealed that the extensive genetic architecture of lateral organ organogenesis and development via CsPID regulating auxin polar transport action in cucumber.

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.

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:In this study, Agrobacterium tumefaciens containing recombinant plasmids were used to agroinoculate cucumber seedlings with tandem repeats of DNA-A genome of Tomato leaf curl New Delhi virus (ToLCNDV). The inoculated seedlings, representing both resistant and susceptible accessions, were monitored for symptoms over a period of four weeks. Symptom development was observed in susceptible genotypes, while the resistant genotype remained symptomless. Leaf samples were collected from both agroinoculated and control plants for further analysis. This research sheds light on the pathogenicity of ToLCNDV in cucumber and highlights the potential resistance mechanisms in certain accessions.
