Project description:Tomato fruit ripening is associated with a dramatic increase in susceptibility to the fungal pathogen Botrytis cinerea, the causal agent of gray mold. Mature green fruit, prior to ripening, are largely resistant to B. cinerea, whereas red fruit, at the end of ripening, are susceptible to B. cinerea infection. We used microarrays to detail the gene expression changes that are induced by B. cinerea when tomato fruit at unripe and ripe stages are infected. Keywords: plant responses to pathogens

We used microarrays to detail the gene expression changes that are induced by B. cinerea when tomato fruit at unripe and ripe stages are infected. Experiment Overall Design: Tomato fruit at mature green and red ripe stages were wound inoculated with a water suspension of B. cinerea conidia. Twenty four hours post inoculation fruit pericarp and epicarp tissue around and including the inoculation sites was collected and the total RNA extracted. Total RNA was also collected from healthy and mock inoculated fruit.

Project description:Leaf mold disease caused by Cladosporium fulvum is a major disease in cultivated tomato plants and affects global tomato production. Some Cf genes, of which Cf-16 is an effective gene for resisting tomato leaf mold, are associated with leaf mold resistance; however, the molecular mechanism is largely unknown. We used comparative transcriptome analysis of C. fulvum-resistant (cv. Ontario7816, including the Cf-16 gene) and C. fulvum-susceptible (cv. Moneymaker) tomato lines to identify differentially expressed genes (DEGs) at 4 and 8 days postinfection with C. fulvum. Our results provide new insights into the resistance response mechanism of Cf genes to C. fulvum, especially the unique characteristics of Cf-16 in response to C. fulvum infection.

Project description:Purpose: Grafting is a commonly used cultural practice to counteract salt stress and is especially important for vegetable production. However, it is not clear which metabolic processes and genes are involved in the response of tomato rootstocks to salt stress. Our goals is to elucidate the regulatory mechanism through which grafting enhances salt tolerance. Methods: The salt-sensitive tomato variety Zhongza 9 and the strongly salt-tolerant tomato rootstock variety QZ-006 (selected by the research group in the early stage) were used as experimental materials and were purchased from the Vegetable and Flower Institute of the Chinese Academy of Agricultural Sciences (Beijing, CHN) and Beijing Kaixingelin Agricultural Technology Co., Ltd. (Beijing, CHN)；The leaves of the seedlings of every sample was added to 5 mL of HNO3 (65%~68%) after they were heated in a microwave digestion system for 2~3 hours；RNA-seq libraries were sequenced on an Illumina HiSeq X Ten platform；qRT‒PCR was performed according to the instructions of a Fast Super EvaGreen qPCR Master Mix Kit (US Everbright®, Inc.)；The amino acid contents in the tomato leaves were calculated by the external standard method. The chlorophyll of the seedlings was extracted with acetone-ethanol (1:1) ；An indirect enzyme-linked immunosorbent assay (ELISA) was used to determine auxin (IAA), gibberellin (GA), cytokinin (ZR), brassinolide (BR), abscisic acid (ABA), jasmonic acid (JA) and salicylic acid (SA) contents, and kit purchased from ThermoFisher Scientific Co., Ltd. (USA). Endogenous ethylene (ETH) was collected, fixed and determined according to the methods of Ling (Ling et al.,2008) using a Shimadzu 2010 gas chromatograph equipped with a hydrogen flame ion detector. ETH standard gas was purchased from Sigma Company. Results: Compared with the NGS, the GSs were more salt tolerant, and the Na+ content in the leaves decreased significantly. Through transcriptome sequencing data analysis of 36 samples, we found that GSs exhibited more stable gene expression patterns, with a lower number of DEGs. WRKY and PosF21 transcription factors were significantly upregulated in the GSs compared to the NGSs. Moreover, the GSs presented more amino acids, a higher photosynthetic index and a higher content of growth-promoting hormones. The main differences between GSs and NGSs were in the expression levels of genes involved in the BR signalling pathway, with significant upregulation of XTHs. Conclusions: Our study demonstrates that grafting on salt tolerant rootstocks can bring different metabolic processes and transcription levels changes to scion leaves, thereby the scion leaves show stronger salt tolerance. This information provides new insight into the mechanism underlying tolerance to salt stress regulation and provides useful molecular biological basis for improving plant salt resistance.

Project description:ELICITOM project aims to decipher the complex regulation of tomato induced resistance to pathogens. Here, we use a classical elicitor of tomato defenses, ie beta-aminobutyric acid (BABA). This unusual amino acid triggers a strong resistance to the oomycete pathogen Phytophthora parasitica as well as to Oidium neolycopersici (powdery mildew) to a lesser extent. No resistance could be observed towards the grey mold (Botrytis cinerea). Transcriptomic data were generated from RNA extracted from tomato leaves (Solanum lycopercum cv "Marmande") sprayed with 10 mM BABA compared to control organs treated with water, 24 h after treatment. Mapping was achieved on Solanum lycopersicum cv Heinz1706 genome (release ITAG2,3).

Project description:The commercial tomato cultivar âKommeetâ was grafted either onto the tomato cultivar âMoneymakerâ (sub-optimal temperature sensitive) or onto the line accession âLA 1777â of the wild tomato species S. habrochaites (sub-optimal temperature tolerant) in a heated glasshouse. Grafted tomato plants were grown in a nutrient film technique system with re-circulating nutrient solution resulting in different root temperature (T), which was either optimal (day and night 25±0.6°C) or sub-optimal (day and night 15±0.4°C) while the air T was optimal (day and night 25±0.6°C) throughout the experimental procedure. After 30 days of differential treatment, differences in growth, physiology, and global gene expression in roots and leaves of all grafting and T combinations were investigated.
