Heat stress in 7 Solanaceae species, replicate 1 and 2

ABSTRACT: Seven different Solanaceae species, Potato (Solanum tuberosum), Tomato (Solanum lycopersicum), Eggplant (Solanum melongena), Pepper (Capsicum annuum), Tobacco (Nicotiana tabacum), Petunia and Nicotiana benthamiana were subjected to heat stress. Plants were grown for 4-6 weeks at 25 C after which heat stress was initiated by exposing the plants to 35 C for 6, 12, 24, 48 and 96 hours. Control samples were isolated from plants just before initiating the heat stress. RNA was isolated using Qiagen RNeasy. Keywords: Direct comparison

Project description:Seven different Solanaceae species, Potato (Solanum tubersosum), Tomato (Solanum lycopersicum), Eggplant (Solanum melongena), Pepper (Capsicum annuum), Tobacco (Nicotiana tabaccum), Petunia and Nicotiana benthiamana were subjected to drought stress. Drought stress was applied by stopping watering of the plants, control plants were normally watered with nutrient solution. Samples were collected at 0, 1, 3, 5, 7 and 10 days after the first application of the drought stress. RNA was isolated using Qiagen RNeasy. Keywords: Direct comparison

Project description:Seven different Solanaceae species, Potato (Solanum tubersosum), Tomato (Solanum lycopersicum), Eggplant (Solanum melangena), Pepper (Capsicum annuum), Tobacco (Nicotiana tabaccum), Petunia and Nicotiana benthiamana were subjected to salt stress. The stress applied was 150mM NaCl and control plants were watered without the additional salt. Samples were collected at 0, 6, 12, 24, 48 and 96 hours after the first application of the salt. RNA was isolated using Qiagen RNeasy. Keywords: Direct comparison

Genome-wide identification of eggplant (Solanum melongena L.) miRNAs and their targets reveals differential regulation of heterostyly [Seq]

Project description:MicroRNAs (miRNAs), a class of endogenous, non-coding, ~21 nucleotide RNAs, regulate the expression of their target genes by mRNA cleavage or translation inhibition. In plants, miRNAs have been demonstrated to play crucial roles in regulating diverse cellular, physiological, and developmental processes. The identification of all the miRNAs is not yet complete; there are no studies on their possible links with the difference in heterostyly observed in eggplant (Solanum melongena L.).

Genome-wide identification of Argonautes in Solanaceae with emphasis on potato

Project description:Regulatory small RNAs (sRNAs) play important roles in many fundamental processes in plant biology such as development, fertilization and stress responses. The AGO protein family has here a central importance in gene regulation based on their capacity to associate with sRNAs followed by mRNA targeting in a sequence-complementary manner. The present study explored Argonautes (AGOs) in the Solanaceae family, with emphasis on potato, Solanum tuberosum (St). A genome-wide monitoring was performed to provide a deeper insight into gene families, genomic localization, gene structure and expression profile against the potato late blight pathogen Phytophthora infestans. Among 15 species in the Solanaceae family we found a variation from ten AGOs in Nicotiana obtusifolia to 17 in N. tabacum. Comprehensive analyses of AGO phylogeny revealed duplication of AGO1, AGO10 and AGO4 paralogs during early radiation of Solanaceae. Fourteen AGOs were identified in potato. Orthologs of AGO8 and AGO9 were missing in the potato genome. However, AGO15 earlier annotated in tomato was identified. StAGO15 differs from the other paralogs having residues of different physico-chemical properties at functionally important amino acid positions. Upon pathogen challenge StAGO15 was significantly activated and hence may play a prominent role in sRNA-based regulation of potato defense.

High-throughput sequencing of eggplant small RNAs

Project description:MiRNAs are a class of non-coding, small RNAs that play important roles in the regulation of gene expression. Although plant miRNAs have been extensively studied in model systems, less is known in other plants with limited genome sequence data, including eggplant (Solanum melongena L.). To identify miRNAs in eggplant and their response to Verticillium dahliae infection, a fungal pathogen for which effective cure methods and a clear understanding of its mechanisms are currently lacking, we deep-sequenced two small RNA (sRNA) libraries prepared from mocked and infected seedlings of eggplants. Specifically, 30,830,792 reads produced 7,716,328 unique small RNAs have been identified.

Solanum torvum transcriptional responses to nematodes

Project description:Solanum torvum Sw is worldwide employed as rootstock for eggplant cultivation because of its vigour and resistance/tolerance to the most serious soil-borne diseasesas bacterial, fungal wilts and root-knot nematodes. A 30,0000 features custom combimatrix chip was designed and microarray hybridizations were conducted for both control and 14 dpi (day post inoculation) with Meloidogyne incognita-infected roots samples. We also tested the chip with samples from the phylogenetically-related nematode-susceptible eggplant species Solanum melongena.The genes identified from S. torvum catalogue, bearing high homology to knownnematode resistance genes, were further investigated in view of their potential role in the nematode resistance mechanism. total RNA was extracted from control and 14 days post-infection (infection with root-knot nematode Meloidogyne incognita) from roots of Solanum torvum and Solanum melongena. Three biological replicates were used for each condition and genotype for a total of 12 samples.
