Project description:The Zinc Finger Transcription Factor SlZFP2 Negatively Regulates Abscisic Acid Biosynthesis and Fruit Ripening in Tomato
| PRJNA269239 | ENA
Project description:Abscisic acid (ABA) regulates seed and bud dormancy. We show by forward and reverse genetic analysis that the tomato transcription factor SlZFP2 is required for release of bud and seed dormancy through negative regulation of ABA biosynthesis. We also demonstrated that ABA promotes growth and represses flowering in tomato both through transcriptional control on the florigen-encoding gene SINGLE FLOWER TRUSS (SFT) in tomato. To gain further insight on transcriptome changes by overexpresion of HA-SlZFP2, we sequenced two lines of p35S:HA-SlZFP2 in LA1589 background and their nontransgenic siblings on Illumina Hiseq2000 platform.

Two homozygous transgenic lines 103 and 104 showing very similar phenotypes in flowering and branching were chosen for profiling gene expression via RNA sequencing. Their respective nontransgenic siblings were served as controls (103N and 104N).

Project description:Background: Tomato (Solanum lycopersicum) self-compatibility (SC) is defined as self-pollen tubes that can penetrate their own stigma, elongate in the style and fertilize their own ovules. Self-incompatibility (SI) is defined as self-pollen tubes that are prevented from developing in the style. To determine the influence of gene expression on style self-pollination, a transcriptome-wide comparative analysis of SC and SI tomato unpollinated/pollinated styles was performed using RNA-sequencing (RNA-seq) data. Results: Transcriptome profiles of 24-h unpollination (UP) and self-pollination (P) styles from SC and SI tomato species were generated using high-throughput next generation sequencing. From the comparison of SC self-pollinated and unpollinated styles, 1341 differentially expressed genes (DEGs) were identified, of which 753 were downregulated and 588 were upregulated. From the comparison of SI self-pollinated and unpollinated styles, 804 DEGs were identified, of which 215 were downregulated and 589 were upregulated. Nine gene ontology (GO) terms were enriched significantly in SC and 78 GO terms were enriched significantly in SI. A total of 105 enriched Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways were identified in SC and 80 enriched KEGG pathways were identified in SI, among which “Cysteine and methionine metabolism pathway” and “Plant hormone signal transduction pathway” were significantly enriched in SI. Conclusions: This study is the first global transcriptome-wide comparative analysis of SC and SI tomato unpollinated/pollinated styles. Advanced bioinformatic analysis of DEGs uncovered the pathways of “Cysteine and methionine metabolism” and “Plant hormone signal transduction”, which are likely to play important roles in the control of pollen tubes growth in SI species. 24-h unpollination (UP) and self-pollination (P) styles mRNA profiles from SC and SI tomato species were generated by deep sequencing, in triplicate, using Illumina Hiseq 2500 platform.

Project description:Leafy spurge (Euphorbia esula) is an herbaceous perennial weed that produces vegetatively from an abundance of underground adventitious buds. The objectives of this study were to determine how mimicking natural seasonal conditions (photoperiod and temperature) under controlled environmental conditions affect dormancy and flowering competence; to determine molecular mechanisms associated with well-defined phases of seasonal dormancy transitions based on transcript profiles obtained by microarray analysis; and to link mechanisms regulating induction and release of endodormancy and flowering competence. Reduction in temperature (27 to 10°C) and photoperiod (16 to 8 h) over a three-month period induced a para- to endo-dormant transition in crown buds. An additional eleven weeks of prolonged cold (5-7°C) and short-photoperiod treatment resulted in accelerated shoot growth from crown buds, and 99% floral competence when plants were returned to growth promoting conditions. Exposure of paradormant plants to short-photoperiod and prolonged cold treatment alone had minimal affect growth potential or on flowering (~1%); whereas endodormant crown buds without prolonged cold treatment, had delayed shoot growth and approximately 2% flowering when returned to growth promoting conditions. Transcriptome analyses revealed that 373 and 260 genes were differentially expressed (p<0.005) during para- to endo-dormant and endo- to eco-dormant transitions, respectively. Transcripts from flower competent vs. non-flower competent crown buds identified 607 differentially expressed genes, and genes involved in cell cycle and DNA processing, oxidative stress, flower regulation, and proteolysis were over-represented. Further, sub-network analysis identified expression targets and binding partners associated with circadian clock, dehydration/cold signaling, phosphorylation cascades, and response to abscisic acid, ethylene, gibberellic acid, and jasmonic acid, suggesting these central regulators affect well-defined phases of dormancy. Potential genetic pathways associated with these dormancy transitions and flowering were used to develop a proposed conceptual model.

Project description:Tomato flowering and fruit set require an optimal temperature of 25/22 ± 2˚C (day/night). When the air temperature reaches to above the optimal range (higher than 30/26˚C; day/night), only a small number of flower buds would develop into mature flowers and produce a reduced number of pollen. This project used the iodoTMT proteomics analysis method to identify heat-induced proteomes in these tomato flower buds.

Project description:In this study, we explored the metabolome and transcriptome of the ripe fruit in nine landrace accessions representing the seven genetic groups and compared them to the mature fruit of the wild progenitor S. pimpinellifolium. The goal is to shed light in understanding the factors responsible for acquiring tomato fruit quality (taste and flavour) at molecular level during the domestication process.
