Project description:transcriptome sequencing was performed to analyze the gene expression profiles of Eriocheir sinensis under normal temperature (22°C) and high temperature (27°C, 32°C) conditions. The differentially expressed genes (DEGs) were identified to provide key molecular targets for elucidating the mechanisms by which temperature affects molting and development in E. sinensis.
Project description:High temperature during the grain-filling stage causes deleterious effects on storage material accumulation and grain quality. But it is still unclear how high temperature affects storage materials accumulation. In this study, we systemically analyzed the expression pattern of rice genes under high temperture during the grain-filling stage.
Project description:High temperature influences plant development and can reduce crop yields. We used the Agilent Barley Gene Expression Microarray to identify high temperature responsive genes in cereals. In temperate cereals, such as wheat and barley, high temperature results in rapid progression through reproductive development in long-days but inhibits early stages of reproductive development in short-days. We examined the transcriptome of barley plants grown at two different temperatures, 15°C or 25°C, in either long or short-days. Under these conditions early reproductive development was accelerated by high temperature in long-days but inhibited by high temperature in short-days. To control for the effect of temperature on vegetative growth, plants were sampled at the same stage of vegetative development (leaf emergence) in all treatments. Transcriptome analysis identified genes that show changed transcript levels in response to daylength (long versus short-days), genes that show changed transcript levels in response to temperature (15°C versus 25°C), and small groups of genes that show changed transcript levels only in response to specific combinations of daylength and temperature. For example, genes that are upregulated only under long-days and high temperature: conditions in which early reproductive development proceeds rapidly. The temperature responsive genes identified here offer potential candidates for developmental regulators controlling the developmental response of cereal crops to high temperatures.
