Priming of tomato mother plants using chemical elicitors linked to whole genome DNA methylation.

ABSTRACT: Inbred parental lines of two cultivars (cv Moneyberg and cv Bolstar Granda) of the model crop tomato were primed (induced for resistance) during four different moments in their development, i.e. once in the vegetative phase (time window 1), once in the generative phase at early flowering (time window 2), multiple times in the generative phase during flowering (time window 3), and once during ripening of the first fruit bunch (time window 4). The primers were ß-aminobutyric acid (BABA), 2,6-dichloroisonicotinic acid (INA), methyljasmonate (MeJA), and water as control; they were selected for their ability to induce different plant resistance pathways. After collecting seed batches from these plants we here look at the effect of priming the tomato plants with those different chemicals on the plant genome methylation level.

Real-time quantitative PCR analysis of tomato bZIP genes in various tissues

Project description:We used Bio-Rad laboratories, lnc. PCR assay panel to analyze expression levels of bZIP genes in various tissues or organs. Tomato (Solanum lycopersicum) cv. Suhong 2003 were reared in growth chambers at 24 ± 1 °C with a photoperiod of 14 h light/10 h dark and light intensity of 200 μE m2 s-1. The roots, stem,leaves, flower, and fruits were collected from flowering plants for tissue expression analysis.

Comparative transcriptome analysis between resistant and susceptible tomato lines uncovers the response mechanism of Cf-16-mediated resistance to Cladosporium fulvum

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.

ELICITOM

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).

Antagonistic activities of co-transcriptional regulators within an early developmental window sets quantitative FLC expression

Project description:Quantitative variation in expression of the Arabidopsis floral repressor FLC influences whether plants overwinter before flowering or have a rapid cycling habit, enabling multiple generations a year. Genetic analysis has identified activators and repressors of FLC expression, but how they interact to set expression level is poorly understood. Here, we show that antagonistic functions of the FLC activator FRIGIDA (FRI), and the repressor FCA, at a specific stage of embryo development, determines FLC expression and flowering. FRI antagonizes an FCA-induced proximal polyadenylation to increase FLC expression and delay flowering. Sector analysis shows that FRI activity during the early heart stage of embryo development maximally delays flowering. Opposing functions of co-transcriptional regulators during an early embryonic developmental window thus set FLC expression levels and determine flowering time.
