iSB09 and iCB elicit ABA-responsive gene expression in Solanum lycopersicum seedlings

Project description:To compare the genome-wide transcriptional effect of ABA and iSB09 in tomato plants, we performed RNA-seq analysis of mock-, 10 uM ABA- or 20 uM iSB09-treated plants. Differential gene expression analysis between mock- and ABA-treated or iSB09-treated seedlings was done with DESeq2 and genes with an absolute value of log2 fold change (log2FC) > 1 or (log2FC) < -1 and p-adjusted value (padj) < 0.05 were selected. iSB09 upregulated and downregulated genes represent a subset of the ABA-responsive genes, which reflects the activation of PYL1-like and PYL4-like ABA receptors in tomato seedlings. Additionally, to compare the genome-wide transcriptional effect of ABA and iCB in tomato plants, we performed RNA-seq analysis of mock-, 10 uM ABA- or 10 uM iCB-treated plants. Differential gene expression analysis between mock- and ABA-treated or iCB-treated seedlings was done with DESeq2 and genes with an absolute value of log2 fold change (log2FC) > 1 or (log2FC) < -1 and p-adjusted value (padj) < 0.05 were selected. iCB mimics ABA transcriptional response through activation of the three subfamilies of ABA receptors.

iCB elicits ABA-responsive gene expression in Arabidopsis thaliana seedlings

Project description:To compare the genome-wide transcriptional effect of ABA and iCB in tomato plants, we performed RNA-seq analysis of mock-, 10 uM ABA- or 10 uM iCB-treated plants. Differential gene expression analysis between mock- and ABA-treated or iCB-treated seedlings was done with DESeq2 and genes with an absolute value of log2 fold change (log2FC) > 1 or (log2FC) < -1 and p-adjusted value (padj) < 0.05 were selected. iCB upregulated and downregulated genes represent almost all the ABA-responsive genes, which reflects the activation of PYL1-like and PYL4-like and PYL8-like ABA receptors in tomato seedlings.

RNA-seq analysis of ABA-treated Nicotiana benthamiana seedlings

Project description:Analysis of abscisic acid (ABA) perception and signaling in crops is complicated by the multigenic nature of the PYR/PYL/RCAR ABA receptor family and the reported functional redundancy, which is a formidable challenge, particularly in polyploid plants. Therefore, few molecular genetics studies have been performed in crop species to study the contribution of ABA signaling to balance plant growth and adaptation to the environment. Our data reveal ABA-responsive genes in Nicotiana benthamiana, an allotetraploid biotech crop, and provide a molecular framework for gene expression analyses aimed at optimizing plant growth and environmental adaptation in agriculture. To obtain the genome-wide transcriptional effect of ABA in Nb WT plants, we performed RNA-seq studies as described in experimental procedures. Differential gene expression analysis between mock- and ABA-treated seedlings was done with DESeq2 and genes with an absolute value of log2 fold change (log2FC) > 1 or (log2FC) < -1 and p-adjusted value (padj) < 0.05 were selected

Immunologic and clinical activity to ICB combinations in DAPPER Leiomyosarcoma cohort

Project description:Non-inflamed (cold) tumors such as leiomyosarcoma (LMS) do not benefit from immune checkpoint blockade (ICB) monotherapy. Combining ICB with angiogenesis-, or poly-ADP ribose polymerase (PARP) inhibitors may increase tumor immunogenicity by altering the immune cell composition of the tumor microenvironment (TME). The DAPPER phase II study evaluated the safety, immunologic, and clinical activity of ICB-based combinations in pre-treated LMS patients.

Overexpression of OsERF106MZ promotes root growth in rice seedlings by relieving the ABA-mediated inhibition of root growth

Project description:Background: Roots are essential for plant growth and serve a variety of functions, such as anchoring the plant to the ground and absorbing water and nutrients. OsERF106MZ is a salinity-induced gene that is expressed in germinating seeds and the roots of rice seedlings. However, the roles of OsERF106MZ in root growth remain poorly understood. Results: Histochemical staining of GUS (β-glucuronidase) activity in transgenic rice seedlings harboring OsERF106MZp::GUS indicated that OsERF106MZ is mainly expressed in the exodermis, sclerenchyma layer, and vascular system of roots. Overexpression of OsERF106MZ in rice seedlings leads to an increase in the length of primary roots (PRs). The expression of the ABA (abscisic acid) biosynthetic gene, OsAO3, is downregulated in OsERF106MZ-overexpressing roots under normal conditions, while the expression of OsNPC3, an AtNPC4 homolog involved in ABA sensitivity, is reduced in OsERF106MZ-overexpressin roots under both normal and NaCl-treated conditions. Under normal conditions, OsERF106MZ-overexpressing roots have a significantly low level of ABA; moreover, exogenous application of 1.0 µM ABA can suppress the OsERF106MZ-mediated promotion of root growth. Meanwhile, OsERF106MZ-overexpressing roots display less sensitivity to the ABA-mediated inhibition of root growth, when they are treated with ABA at 5.0 µM under normal conditions or exposed to NaCl-treated conditions. Chromatin immunoprecipitation (ChIP)-qPCR and luciferase (LUC) reporter assays showed that OsERF106MZ can bind directly to the sequence containing the GCC-box in the promoter region of OsAO3 gene and repress its expression. Conclusion: OsERF106MZ may play a role in maintaining root growth for resource uptake when rice seeds are sprouted under salinity stress, which is arrived at by alleviating the ABA-mediated inhibition of root growth.

Gene expression data from ABA, [5-(3,4-Dichlorophenyl)Furan-2-yl]-Piperidin-1-ylMethanethione (DFPM), and ABA+DFPM treated Arabidopsis thaliana seedlings.

Project description:Coordinated regulation of protection mechanisms against environmental abiotic stress and pathogen attack is essential for plant adaptation and survival. Initial abiotic stress can interfere with disease resistance signaling. Conversely, initial plant immune signaling may interrupt subsequent ABA signal transduction. However, the processes involved in cross talk between these signaling networks have not been determined. By screening a 9,600 compound chemical library, we identified a small molecule [5-(3,4-Dichlorophenyl)Furan-2-yl]-Piperidin-1-ylMethanethione that rapidly down-regulates ABA-dependent gene expression and also inhibits ABA-induced stomatal closure. Transcriptome analyses show that DFPM also stimulates expression of plant defense-related genes. Plate grown 12-day-old seedlings were transferred into 6 well plates with 1:5000 (V/V) DMSO in water as a control, 30uM DFPM, and 10uM ABA in water as a treatment for 6 hours. DFPM was added 30 min prior to ABA treatment. RNA was extracted using Trizol (Invitrogen, Carlsbad, CA, USA) and further purified using RNeasy Plant RNA purification kit (QIAgen, Valencia, CA, USA). Three biological replicates of ATH1 oligonucleotide arrays were hybridized with labeled samples from 1) wild-type Columbia (WT) untreated, 2) WT with 30uM DFPM treatment, 3) WT with 10uM ABA treatment, 4) WT with 30uM DFPM and 10uM ABA treatment. Each biological replicate was prepared by combining 7 independently-treated samples.
