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).

Project description:The biocontrol agent Pythium oligandrum, which is a member of phylum Oomycota, can control diseases caused by a taxonomically wide range of plant pathogens, including fungi, bacteria, and oomycetes. However, whether P. oligandrum could control diseases caused by plant root-knot nematodes (RKNs) was unknown. We investigated a recently isolated P. oligandrum strain GAQ1, and the P. oligandrum CBS530.74 strain, for the control of RKN Meloidogyne incognita infection of tomato (Solanum lycopersicum L.). Initially, P. oligandrum culture filtrates were found to be lethal to M. incognita second-stage juveniles (J2s) with up to 84% mortality at 24 h after treatment compared to 14% in the control group. Consistent with the lethality to M. incognita J2s, tomato roots treated with P. oligandrum culture filtrates reduced the attraction of nematodes, and the number of nematodes penetrating the roots was reduced by up to 78%. In a greenhouse pot trial, P. oligandrum GAQ1 inoculation of tomato plants significantly reduced the gall number by 58% in plants infected with M. incognita. Notably, P. oligandrum GAQ1 mycelial treatment significantly increased tomato plant height (by 36%), weight (by 27%), and root weight (by 48%). Transcriptome analysis of tomato seedling roots inoculated with the P. oligandrum GAQ1 strain identified ~2,500 differentially expressed genes. The enriched GO terms and annotations in the up-regulated genes suggested modulation of plant hormone-signaling and defense-related pathways in response to P. oligandrum. In conclusion, our results support that P. oligandrum GAQ1 can serve as a potential biocontrol agent for M. incognita control in tomato. Multiple mechanisms appear to contribute to the biocontrol effect involving direct inhibition of M. incognita, potential priming of tomato plant defenses, and plant growth promotion.

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.
