Project description:Iron (Fe) deficiency is a yield-limiting factor for a variety of field crops across the world and generally results from the interaction of limited soil Fe bioavailability and susceptible genotype cultivation. Tomato, a Strategy I, model plant for Fe deficiency, is an important economical crop. Tomato responses in order to improve Fe uptake are based on acidification of rhizosphere, reduction of Fe3+ to Fe2+ and transport of Fe2+ into the cells. Transcriptional profile obtained by roots (27-d) of 21-d-old tomato plants starved of iron for an additional week was compared with the transcriptional profile obtained for roots (27-d) of 21-d-old tomato plants grown for an additional week at 100 M-NM-<M Fe. Tomato plants were hydroponically grown in both cases. Three different biological replicates were used for each sample repeating the experiment three times. All samples were obtained pooling roots of six plants (27-d-old).

Project description:RKNs are economically most damaging, obligate sedentary endoparasites that form giant cells within host roots to obtain nutrition and complete their life cycle. We report genome-wide identification of miRNAs from both host and RKN using RKN-infected susceptible tomato roots through high-throughput sequencing. Eleven small RNA libraries were made from five disease development stages, their five corresponding uninfected development stages and uninfected development stage 0. A total of 52 conserved miRNAs, 4 variants of conserved miRNAs and 281 novel miRNAs of host were identified. A significantly upregulated expression of majority of the miRNAs was observed during susceptible response and downregulated expression during resistance response through qRT-PCR. The miRNA targets were predicted and validated through 5’RLM-RACE. Furthermore, correlation between the expression profile of selected conserved miRNAs viz., miR164, miR156, miR396, miR159, and novel Sly_miRNA996 with their target transcription factors viz., NAC, SBP, GRF1, GAMYB-like, and MYB-like, respectively was also determined. This study suggests a potential role of host miRNAs in regulating transcription factor genes involved in plant developmental processes and defense responses during RKN infection. Additionally, 328 RKN miRNAs including 38 conserved miRNAs, 106 novel miRNAs, and 184 candidate novel miRNAs were identified from same dataset. The differential expression of conserved and RKN-specific miRNAs at different development stages of nematode in tomato roots suggests their probable role during nematode development and adaptation to parasitic behavior. This is the most comprehensive study reporting the identification and characterization of miRNAs from both tomato and RKN in five different disease development stages under soil grown conditions and their potential roles during RKN infection in tomato roots.

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:Tomato, a Strategy I model plant for Fe deficiency, is an important economical crop. The transcriptional responses induced by Fe deficiency in tomato roots were previously described (Zamboni et al., 2012). The changes in trascriptome caused by the supply of Fe to plants starved fro 1 week were described in relation to the different nature of chelating agents (Fe-WEHS, Fe-CITRATE and Fe-PS). Transcriptional profile obtained by roots (27-d) of 21-d-old tomato plants starved of iron (0 μM Fe-EDTA) for 1 week and supplied for 1 h with 1 μM of Fe as Fe-WEHS (supply_Fe_WEHS), Fe citrate (supply_Fe_CITRATE) and Fe-PS (supply_Fe_PS). Tomato plants were hydroponically grown in all three case of Fe supply. Three different biological replicates were used for each sample repeating the experiment three times. All samples were obtained pooling roots of six plants (27-d-old).

Project description:This work aims to study the effect of the elevated CO2 concentration on the tomato plant response to the toxicity provoked by ammonium nutrition. Tomato plants (Solanum lycopersicum L. cv. Agora Hybrid F1, Vilmorin®) were grown for 4 week with 15 mM of nitrogen, supplied as nitrate or ammonium, at ambient or elevated CO2 conditions (400 ppm or 800 ppm). Transcription profiling by array was carried out in roots for the four growth conditions assayed and gene expression comparisons were done between N sources and CO2 conditions: i) genes differentially expressed in response to the atmospheric CO2 concentration (800 ppm vs 400 ppm CO2) under nitrate or ammonium nutrition; ii) genes differentially expressed in response to the N source (ammonium vs nitrate) under ambient or elevated condition. 3 biological replicates for each growth condition were analysed.CO2).
