Transcriptome analysis of Arabidopsis VIRE2-INTERACTING PROTEIN2 Overexpressor in Agrobacterium-mediated plant transformation and abiotic stresses

ABSTRACT: VIP2 is a transcription regulator and the C-terminal NOT2 domain of VIP2 interacts with VirE2. However, AtVIP2 overexpressor lines in Arabidopsis did not show an improvement in Agrobacterium-mediated stable root transformation. To investigate the role of VIP2 in Agrobacterium-plant interaction, we carried out transcriptome profiling by comparing a homozygous Arabidopsis AtVIP2 overexpressor line with wild-type Col-0 plants following Agrobacterium infection.

Transcription profiling of Arabidopsis inflorescence stalks of intact plants after infection with A. tumefaciens

Project description:The intention of these gene expression analysis was to study host responses to an infection with Agrobacterium tumefaciens at different stages of crown gall development. Therefore the transcriptome of infected inflorescence stalk tissue and mature crown galls of Arabidopsis thaliana (WS-2) was determined of three different time points. These were compared with the transcriptome of mock-infected inflorescence stalk tissue (reference) of the same age. The following time points were analyzed: (i) three hours post inoculation, before the T-DNA is integrated into the host genome (ii) six days after inoculation when the T-DNA is present in the nucleus and the oncogenes are expressed in the host cell, and (iii) 35 days after inoculation when a mature tumors has developed. For the three-hour- (3hpi) and six-day- time point (6dpi) plants were infected with the virulent strain C58, harboring a T-DNA, or with strain GV3101, containing a disarmed Ti-plasmid. This allows discrimination between signals which derive from the bacterial pathogen and the T-DNA encoded oncogenes. This SuperSeries is composed of the following subset Series:; GSE13929: Arabidopsis thaliana three hours after infection with Agrobacterium tumefaciens; GSE13930: Arabidopsis thaliana six days after infection with Agrobacterium tumefaciens; GSE13927: Transcriptome of mature A. thaliana crown galls. Experiment Overall Design: Refer to individual Series

To russet or not to russet: MdMyb93 as a regulator of suberin deposition in apple fruits

Project description:â¢ A comparison of the transcriptomes of russeted vs. waxy apple exocarps previously highlighted a tight relationship between a gene encoding a MYB-type transcription factor, MdMYB93, and some key suberin biosynthetic genes. The present work assesses the role of this transcription factor in the suberization process. â¢ A phylogenetic analysis of MdMYB93 and Arabidopsis thaliana MYBs was performed and the function of MdMYB93 was further investigated using Agrobacterium-mediated transient overexpression in Nicotiana benthamiana leaves. An RNA-Seq analysis was performed to highlight the MdMYB93-regulated genes. UPLC-TripleTOF and GC-MS were used to investigate alterations in phenylpropanoid, soluble free lipid, and lipid polyester contents. â¢ A massive accumulation of suberin and its biosynthetic precursors in MdMYB93 agro-infiltrated leaves was accompanied by a remobilization of phenylpropanoids and an increased amount of lignin precursors. Gene expression profiling displayed a concomitant alteration of lipid and phenylpropanoid metabolism, cell wall development, and extracellular transport, with a large number of induced transcripts predicted to be involved in suberin deposition. â¢ The present work supports a major role of MdMYB93 in the regulation of suberin deposition in russeted apple skins, from the synthesis of monomeric precursors, their transport, polymerization, and final deposition as suberin in primary cell wall. In order to draw a consistent picture of a gene expression profile of the MYB93 induced was performed comparing of 4 biological replicates of Nicotiana benthamiana leaves infiltrated with Pearleygate103 35S::MdMYB93 and 4 biological replicates of control plants infiltrated with P19 only.

Transcription profiling of Arabidopsis thaliana six days after infection with Agrobacterium tumefaciens

Project description:This study focuses on responses of the host plant to infection and transformation with Agrobacterium tumefaciens. Genome wide changes in gene expression were integrated with the alterations in metabolite levels six days after inoculation of agrobacteria. Plants were infected with the virulent strain C58, harboring a T-DNA, or with strain GV3101, containing a disarmed Ti-plasmid. This allows discrimination between signals which derive from the bacterial pathogen and the T-DNA encoded genes. Experiment Overall Design: The bases of Arabidopsis thaliana (WS-2) inflorescence stalks were wounded and immediately infected with Agrobacterium tumefaciens or mock-infected for six days. Stalks of intact plants were inoculated with the oncogenic strain C58 (C58 6dpi 1 to 3) or the non-virulent strain GV3101 (GV3101 6dpi 1 to 3) to provide conditions close to nature. The gene expression data of three independent experiments of infected material were compared with three non-infected samples (reference 6dpi 1 to 3). Differential gene expression was determined by applying the LIMMA package (Linear Models for Microarray Data; Smyth, G.K. (2004) Applic. Genet. Mol. Biol. 3, Article 3; http://www.bepress.com/sagmb/vol3/iss1/art3/).

Transcription profiling by array of Arabidopsis after infection with different strains of Agrobacterium tumefaciens

Project description:This study focuses on responses of the host plant to infection with Agrobacterium tumefaciens. Genome wide changes in gene expression were integrated with the alterations in metabolite levels three hours after inoculation of agrobacteria. Plants were infected with the virulent strain C58, harboring a T-DNA, or with strain GV3101, containing a disarmed Ti-plasmid. This allows discrimination between signals which derive from the bacterial pathogen and the T-DNA encoded genes. Experiment Overall Design: The bases of Arabidopsis thaliana (WS-2) inflorescence stalks were wounded and immediately infected with Agrobacterium tumefaciens or mock-infected for three hours. Stalks of intact plants were inoculated with the oncogenic strain C58 (C58 3 hpi 1 to 6) or the non-virulent strain GV3101 (GV3101 3 hpi 1 to 3) to provide conditions close to nature. The gene expression data of three independent experiments of infected material were compared with six non-infected samples (reference 3 hpi 1 to 6). Differential gene expression was determined by applying the LIMMA package (Linear Models for Microarray Data; Smyth, G.K. (2004) Applic. Genet. Mol.

Constitutive expression of Medicago truncatula NRT1 PTR FAMILY 1.7 enhances growth in Arabidopsis thaliana

Project description:To gain insight into the molecular mechanisms underlying the increased growth of Col-0:MtNPF1.7 CE plants compared to WT, leaves from plants grown for 21 days on defined media were subjected to transcript profiling using the Affymetrix Arabidopsis ATH1 microarray. We tested gene expression from plants grown at 0.1 mM nitrate and at 10 mM nitrate. The 0.1 mM nitrate concentration is below MtNPF1.7’s Km and at that nitrate concentration, large growth differences between Col-0:MtNPF1.7 CE and wild-type Col-0 plants were observed, while 10 mM nitrate is well above MtNPF1.7’s Km, where fewer differences in growth were seen. Three independent biological replicates were collected.

LC-MSMS of RIBOPROTEOMES OF HEALTHY, POTATO VIRUS A- AND AGROBACTERIUM -INFECTED NICOTIANA BENTHAMIANA PLANTS

Project description:Nicotiana benthamiana is an important model plant for plant-microbe interaction studies. We compared the proteomes of ribosomes purified from healthy N. benthamiana plants and plants that were infected with two plant pathogens potato virus A (PVA genus Potyvirus) and A. tumefaciens bacteria. Ribosomes were affinity purified from transgenic leaves that expressed FLAG-tagged RPL18B (RPL: ribosome protein large subunit) of A. thaliana. Control purifications were made from non-transgenic plants that were infected with PVA. Our riboproteome revealed ~6600 r-protein hits representing 424 distinct r-proteins that were members from 71 of the expected 81 r-protein families.

Arabidopsis thaliana Col-0 leaf transcriptome response to Agrobacterium tumefaciens C58

Project description:As sessile organisms, plants require dynamic pathways in order to recognize pathogens and coordinate plant defenses by signalling. Agrobacterium tumefaciens C58 is able to avoid triggering plant defenses prior to entering the cell, and therefore is only detected once infection has begun making Agrobacterium a plant pathogen to numerous plant species. Understanding plant responses to Agrobacterium will be useful in improving plant defenses and potentially may also improve plant transformation efficiency. Microarrays were utilized for detailing the global gene expression pattern in A. thaliana Col-0 leafs in response to A. tumefaciens C58 for the identification of differentially expressed genes. 3-week-old A.thaliana Col-0 seedlings were selected for growth in hydroponic systems. A. tumefaciens C58 was inoculated into the hydroponic system and co-cultivation persisted for 8 hours. Leaf tissue was seperated for RNA extraction and hybridization to the ATH1 Affymetrix microarray.
