Project description:Arabidopsis thaliana (Col-0) plants were treated with BABA and gene expression differences to control plants were monitored after dip-inoculation with Pseudomonas syringae pv tomato DC3000. Keywords: transcript profiling, response to BABA-induced priming and infection
Project description:Sound vibration (SV) causes various developmental and physiological changes in plants. It strongly suggests the existence of sophisticated molecular mechanisms for SV perception and signaling in plants. However, the underlying molecular mechanism of SV-mediated plant responses remains elusive. Herein, we investigated the transcript changes in Arabidopsis thaliana upon five different single frequencies of SV treatment.
Project description:To prevent activation of plant innate immunity the oomycete pathogen Hyaloperonospora arabidopsidis translocates effector proteins into infected cells of its host Arabidopsis thaliana. We noticed that some H. arabidopsidis effectors, when over-expressed in A. thaliana, render the plant more susceptible to infection by biotrophic pathogens (Fabro et al., 2011, PubMed PMID: 22072967). Here we performed transcriptome profiling of a representative transgenic line constitutively expressing H. arabidopsidis effector HaRxL106. We compared the transcriptomes of A. thaliana wild-type (Col-0) plants and an isogenic line expressing HaRxL106 before pathogen challenge and 24 h after infection with the compatible bacterial pathogen Pseudomonas syringae pv. tomato strain DC3000. HaRxL106 interacts with several Arabidopsis proteins (Mukhtar et al., 2011, PubMed PMID: 21798943; Wirthmueller et al., 2015, PubMed PMID: 25284001). To test whether the HaRxL106-interacting A. thaliana proteins MODIFIER OF SNC1, 6 (MOS6), 6B-INTERACTING PROTEIN 1-LIKE 1 (ASIL1) or RADICAL-INDUCED CELL DEATH1 (RCD1) are altered in their transcriptional response to a biotrophic pathogen we performed transcriptome profiling of mos6-1, asil1-1 and rcd1-1 mutants before and 24 h after infection with P. syringae pv. tomato DC3000.
