Project description:We report the expression analysis of seed kernel in Camellia oleifera cultivars. In total 221 cultivars are sequenced by the Illumina sequencing experiments to obtain the gene expression profiles.
Project description:Composts are the products obtained after the aerobic degradation of different types of organic matter wastes and can be used as substrates or substrate/soil amendments. There are a small but increasing number of reports that suggest that foliar diseases may be reduced when using compost as growing medium compared to standard substrates. The purpose of this study was to unravel the gene expression alteration produced by the compost to gain knowledge about the mechanisms involved in the compost-induced systemic resistance. A compost from olive marc and olive tree leaves was able to induce resistance against Botrytis cinerea in Arabidopsis compared to the standard substrate perlite. Microarray analyses revealed that 178 genes were differently expressed with a fold change cut off of 1 from which 155 were upregulated and 23 were down regulated in compost-grown compared to perlite-grown plants. Functional enrichment study of up regulated genes revealed that 38 Gene Ontology terms were significantly enriched. Response to stress, biotic stimulus, other organism, bacterium, fungus, chemical and abiotic stimulus, SA and ABA stimulus, oxidative stress, water, temperature and cold were significantly enriched terms as well as immune and defense responses, systemic acquired resistance, secondary metabolic process and oxireductase activity. Interestingly, PR1 expression, which was equally enhanced by growing the plants in compost and by B. cinerea inoculation, was further boosted in compost-grown pathogen-inoculated plants. Compost triggered a plant response that shares similarities with both systemic acquired resistance and ABA dependent/independent abiotic stress responses.

Project description:Oral administration of an extract of compost fermented with thermophiles to pigs reduces the incidence of stillbirth and promotes piglet growth. However, the mechanism by which compost extract modulates the physiological conditions of the animals remains largely unknown. Here, we investigate the effects of compost extract on the gene expression in the intestine of the rat as a mammalian model. Gene expression analyses of the intestine indicated that several immune-related genes were upregulated following compost exposure. Thus, thermophile-fermented compost can contain microbes and/or substances that activate the gut mucosal immune response in the rat. In Male Wistar rats aged 3 weeks, tap water was supplemented with 1.0% (v/v) compost extract for the experimental rats, whereas water only was given to the control rats. The rats received water ad libitum for 12 weeks. Fresh gut samples were collected from individual rats at the end of the feeding test and stored at -80°C. The intestine were separated from the gut and used as samples for the isolation of total RNA. otal RNA was then subjected to microarray experiments using the Whole Rat Genome (4x44k) Oligo Microarray (Agilent Technologies, Inc.)

Project description:<p>Oil-tea <em>Camellia</em> is a promising woody oil crop that has been widely used as a cooking oil, lubricant, and cosmetics. However, there is a lack of dominant varieties suitable for high-altitude cold mountainous regions. <em>Camellia weiningensis</em> (<em>C. weiningensis</em>) is the only high-altitude species of the Camellia genus incorporated into Camellia oil production in China, characterized by high oil content and superior quality. However, this species has garnered limited attention and its lipid biosynthesis mechanism remains unexplored. In this study, lipidomic and transcriptomic analyses were conducted across different developmental stages of C. weiningensis. The oil content of C. weiningensis seeds increased continuously during seed development and was rich in unsaturated fatty acids, particularly oleic acid. A total of 1352 lipid molecules were identified, among which triacylglycerol exhibited the highest abundance and diversity. Furthermore, diacylglycerol, phosphatidic acid, and phosphatidylcholine exhibited high relative contents, with an abundance of unsaturated fatty acids especially oleic acid, predominantly located at the sn-2 position. RNA sequencing of developing seeds revealed enhanced expression of genes associated with fatty acid synthesis. Co-expression analysis identified several key structural genes (ACC, SAD, FAD2, DGAT1, PDAT1, and Ole) and transcription factors (MYBs, ERFs, WRKYs, and GRFs) were involved in fatty acid synthesis. These findings provide insights into the molecular mechanisms underlying fatty acid biosynthesis in C. weiningensis seeds, which will be beneficial for increasing the yield of oil-tea Camellia and for breeding superior varieties adapted to cold mountainous areas.</p>
