Project description:Pyrenochaeta lycopersici causes corky root disease of tomato. A comparative RNA-Seq-based transcriptome analysis was conducted at 96 hpi (hours post infection) on two tomato cultivars: the resistant Mogeor and its genetic background, susceptible Moneymaker to investigate the differences in their transcripts and identify the molecular bases of this plant-pathogen interaction and gain hints over resistance mechanisms.
Project description:Transcriptional changes in greenhouse-grown plants of tomato varieties Monaymaker and Mogeor infected with Pyrenochaeta lycopersici compared to uninfected control plants. The objective of the the study was to give an insight into the establishment of compatible and incompatible interactions between tomato and the pathogen using susceptible (Moneymaker) and resistant (Mogeor) varieties of tomato. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Justyna Anna Milc.

Project description:To characterize the PTI response of tomato and the effect of the delivery of a subset of effectors, we performed an RNA-seq analysis of tomato Rio Grande prf3 leaves challenged with either the flgII-28 peptide or the following bacterial strains: Agrobacterium tumefaciens GV2260, Pseudomonas fluorescens 55, Pseudomonas putida KT2440, Pseudomonas syringae pv. tomato (Pst) DC3000, Pst DC3000 deltahrcQ-U deltafliC and Pst DC3000 deltaavrPto deltaavrPtoB. NOTE: Samples in SRA were assigned the same sample accession. This is incorrect as there are different samples, hence âSource Nameâ was replaced with new values. Comment[ENA_SAMPLE] contains the original SRA sample accessions.
Project description:In this experiment we measured the transcriptional response of ten tomato cultivars when infected by the plant-parasitic nematode M. incognita. The ten cultivars showed differential levels of susceptibility to M. incognita infection. Ten-days old plants were exposed to nematodes and harvested 1, 2, 3, 4, 7, or 10 days post infection. Galls or representative uninfected tissues were harvested and used for RNA sequencing. The data was used to investigate the link between susceptibility to M. incognita infection and gene expression in tomato.
Project description:PHYTOCHROME-INTERACTING FACTORs (PIFs) regulate growth-related gene expression in response to environmental conditions. Among their diverse functions in regulating signal responses, PIFs play an important role in thermomorphogenesis (the response to increased ambient temperature) and in the shade-avoidance response. While numerous studies have examined the varied roles of PIFs in Arabidopsis (Arabidopsis Thaliana), their roles in crop plants remain poorly investigated. This study delves into the conservation of PIFs activity among species by examining their functions in tomato (Solanum lycopersicum) and comparing them to known PIF functions in Arabidopsis using single and higher-order mutants of tomato PIF genes (SlPIFs). We demonstrate that, in contrast to Arabidopsis, PIFs are not required for thermomorphogenesis-induced stem elongation in tomato. In addition, whereas Arabidopsis PIF8 has a minor effect on plant growth, tomato SlPIF8a plays a key role in the low red/far-red (R/FR) response. In contrast, SlPIF4 and SlPIF7s play minor roles in this process. We also investigated the tissue-specific low R/FR response in tomato seedlings and demonstrate that the aboveground organs exhibit a conserved response to low R/FR, which is regulated by SlPIFs. Our findings provide insights into PIF-mediated responses in crop plants, which may guide future breeding strategies to enhance yield under high planting densities.
