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:The degree of yellowing in tobacco leaves is an important indicator for determining the maturity and harvesting time of tobacco leaves. Reduction in chlorophyll is of utility for promoting the concentrated maturation of tobacco leaves and achieving mechanised harvesting and mining, and utilising tobacco yellow leaf regulatory genes is of great significance for the selection and breeding of tobacco varieties suitable for mechanised harvesting and the resolution of the molecular mechanisms controlling leaf colouration. In this study, the phenotypes of the yellow-leaf K326 and K326 varieties were analysed, and it was observed that the yellow-leaf K326 variety exhibited a distinct yellow leaf phenotype with a significant reduction in chlorophyll content. Subsequently, using a combination of BSA-seq, transcriptomic sequencing (RNA-seq), and proteomic sequencing approaches, we identified the candidate gene Nitab4.5_0008674g0010 that encodes dihydroneopterin aldolase as a factor associated with tobacco leaf yellowing. Finally, by measuring the folate content in K326 and Huangye K326, the folate content in Huangye K326 was observed to be significantly lower than that in K326, thus indicating that folate synthesis plays a crucial role in phenotypic changes in tobacco yellow leaves. This study is the first to use BSA-seq combined with RNA-seq and proteomic sequencing to identify candidate genes in tobacco yellow leaves. The results provide a theoretical basis for the analysis of the mechanism of tobacco yellow leaf mutations.

Project description:The timing of flower opening is essential for pollination and thus seed production. Despite flower opening has been a long lasting topic for plant biologists, the underling molecular mechansim remains elusive. Here we used a unique cucumber line ‘6457’ that spontaneously produces super ovary with delayed corolla opening as material, and explored the physiological, cytological, nutritional and transcriptomic reasons for the delayed corolla opening in super ovary. Our data showed that cell division and cell expansion persisited for a longer period of time in the super ovary, especially during the green yellow bud stage and yellow bud stage. Similarly, RNA-seq analyses showed that RNA and protein synthesis related genes were upregulated during these two stages, which may account for the decreased nitrogen and phosphrate content in the super ovary. Further, activation of transcription factors were delayed in the green yellow bud stage, while signalling kinases related genes were upregulated in the yellow bud stage in the super ovary. Photosynthesis related genes were also significantly activated in the super ovary, which corresponds to the increased soluble suble content. Phytohoromones such as cytokinins and gibberllins were elevated in the super ovary. Consistently, cytokinins and gibberllins related genes showed significantly enhanced expression. Therefore, both developmental and nutritional factors regulate the timing of female flower opening in cucumber, and provide a valuable foundation for dissecting the underling regulatory pathways of flower opening in planta.

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 timing of flower opening is essential for pollination and thus seed production. Despite flower opening has been a long lasting topic for plant biologists, the underling molecular mechansim remains elusive.

Therefore, both developmental and nutritional factors regulate the timing of female flower opening in cucumber, and provide a valuable foundation for dissecting the underling regulatory pathways of flower opening in planta. The normal ovary blooms at 4-5 days after labeling (when the ovary is visible) (DAL), with the majority blooms at 5 DAL, while the anthesis of super ovary occurs at 8-9 DALs, with most super ovaries blooms at 9 DAL.In the normal ovary, corolla at 1 DAL (N1), 3 DAL (N3), 4 DAL (N4), and 5 DAL (N5) is the typical stage for green bud, green yellow bud, yellow bud, and flowering, respectively, whereas in the super ovary, corolla at 1 DAL (S1) is the green bud, corolla at 3, 4 and 5 DAL (S3, S4, S5) is the green yellow bud, corolla at 7 and 8 DAL (S7, S8) is the yellow bud, and corolla at 9 DAL (S9) is the typical flowering stage.Transcriptome profiling of 11 stages include N1,N3,N4,N5,S1,S3,S4,S5,S7,S8 and S9 were performed, and each stage had 3 biological replicates.

Project description:Nitrogen is the most important mineral nutrient of plant. As a worldwide and economically important vegetable, cucumber (Cucumis sativus L.) has a strong nitrogen-dependence. We took whole transcriptome sequencing approach to compare the gene expression profiles of cucumber leaves and roots grown under sufficient or insufficient nitrate supply. Analysis of the transcriptome data revealed that the root and leaf adapt different response mechanisms to long-term nitrogen deficiency. Photosynthesis and carbohydrate biosynthetic process were pronouncedly and specifically reduced in leaf, while the ion transport function, cell wall and phosphorus-deficiency response function seem systematically down-regulated in root. Genes in nitrogen uptake and assimilation are decreased in root, but some are increased in leaf under nitrogen deficiency. Several lines of evidence suggest that the altered gene expression networks support the basic cucumber growth and development likely through successful nitrogen remobilization involving in the induced expression of genes in ABA and ethylene pathways. cucumber leaf and root mRNA of 28-day after sowing nitrogen deficiency and sufficiency deep sequencing, using Illumina HiSeq 2000

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.
