Project description:This study aimed to investigate the physiological and molecular responses of Solanum lycopersicum (tomato) to Phytophthora cinnamomi infection. The initial defense response in tomato seeds included the production of reactive oxygen species (ROS) and callose deposition. Screening of commercial tomato varieties revealed varying levels of susceptibility, with the variety Marmande exhibiting heightened vulnerability. Three days post-inoculation, Marmande showed increased expression of genes associated with ROS generation, and biosynthesis pathways for phenylpropanoids and flavonoids. Additionally, 850 genes related to cell wall remodeling, including those involved in lignin biosynthesis and pectin methyl esterase inhibitors (PMEIs), were significantly upregulated. Seven days post-inoculation, a stronger transcriptional response was observed, with activation of ethylene (ET) and jasmonic acid (JA) signaling pathways, while salicylic acid (SA) showed minimal activity. Metabolomic analysis of infected roots revealed elevated levels of metabolites linked to lycopene, flavonoids, and phenylpropanoids. Furthermore, infected roots exhibited a significant reduction in pectin levels, which was corroborated by in vitro assays showing zoospore-mediated pectin degradation. These results suggest that degradation of root pectin is a key mechanism facilitating zoospore invasion in susceptible tomato hosts. This study provides new insights into the molecular mechanisms underlying host-pathogen interactions and identifies potential targets for managing Phytophthora cinnamomi-induced diseases in crops.

Project description:Solanum lycopersicum and Solanum tuberosum are agriculturally important crop species as they are rich sources of starch, protein, antioxidants, lycopene, beta-carotene, vitamin C, and fiber. The genomes of S. lycopersicum and S. tuberosum are currently available. However the linear strings of nucleotides that together comprise a genome sequence are of limited significance by themselves. Computational and bioinformatics approaches can be used to exploit the genomes for fundamental research for improving their varieties. The comparative genome analysis, Pfam analysis of predicted reviewed paralogous proteins was performed. It was found that S. lycopersicum proteins belong to more families, domains and clans in comparison with S. tuberosum. It was also found that mostly intergenic regions are conserved in two genomes followed by exons, intron and UTR. This can be exploited to predict regions between genomes that are similar to each other and to study the evolutionary relationship between two genomes, leading towards the development of disease resistance, stress tolerance and improved varieties of tomato.

Project description:BackgroundThe use of light emitting diodes (LEDs) brings several key advantages over existing illumination technologies for indoor plant cultivation. Among these are that LEDs have predicted lifetimes from 50-100.000 hours without significant drops in efficiency and energy consumption is much lower compared to traditional fluorescent tubes. Recent advances allow LEDs to be used with customized wavelengths for plant growth. However, most of these LED growth systems use mixtures of chips emitting in several narrow wavelengths and frequently they are not compatible with existing infrastructures. This study tested the growth of five different plant species under phosphor coated LED-chips fitted into a tube with a standard G13 base that provide continuous visible light illumination with enhanced blue and red light.ResultsThe LED system was characterized and compared with standard fluorescence tubes in the same cultivation room. Significant differences in heat generation between LEDs and fluorescent tubes were clearly demonstrated. Also, LED lights allowed for better control and stability of preset conditions. Physiological properties such as growth characteristics, biomass, and chlorophyll content were measured and the responses to pathogen assessed for five plant species (both the model plants Arabidopsis thaliana, Nicotiana bentamiana and crop species potato, oilseed rape and soybean) under the different illumination sources.ConclusionsWe showed that polychromatic LEDs provide light of sufficient quality and intensity for plant growth using less than 40% of the electricity required by the standard fluorescent lighting under test. The tested type of LED installation provides a simple upgrade pathway for existing infrastructure for indoor plant growth. Interestingly, individual plant species responded differently to the LED lights so it would be reasonable to test their utility to any particular application.

Project description:Rice stripe virus (RSV) causes the general chlorosis symptom and influences expression of numberous chloropalst-related genes at transcriotional level in Nicotiana benthamiana plants, but the mechanism are not well understood. Small RNAs (sRNAs), including virus-derived siRNA (vsiRNA) play roles in modulating genes expression post-transcriptionally. This present work presents multi-omics analysis of the transcriptome, sRNAome and degradome in RSV-infected N.benthamiana plants. Transcriptome-seq profiled 4127 N. benthamiana genes, with differentially expressed genes (DEGs) enriched in functional categories such as metabolic process, protein phosphorylation, regulation of transcription, carotenoid biosynthetic process. We identified 400863, 203874 and 244713 reads of vsiRNA from 3 sRNA libraries of RSV-infected N.benthamiana plants respectively. The degradome-seq report discovered a significant number of N.benthamiana genes that might be regulated by vsiRNAs post-transcriptionally. Based on integrated analysis of the three omics, we provide a substantial amount of novel information on the transcriptional and post-transcriptional networks in RSV-infected N.benthamiana, which will extends our horizon about the interactions between virus and their hosts.
