Project description:Temperature is an important factor that affects the growth and reproduction of mangrove plants. Laguncularia racemosa (L.) C.F. Gaertn is a controversial species in China, in terms of being a pioneer species for mangrove restoration and a putative invasive species occupying the natural habitats. One of its advantages is the strong resistance to low temperature, which makes L. racemose more adaptive to extreme climate change than local mangrove species. However, little is known about the regulatory mechanisms underlying the cold-stress tolerance in L. racemose, which restricted our understanding on its biological features and invasion potential. In this study, In the current study, we investigated the physiological and molecular mechanisms involved in chilling-stress adaptation in L. racemose. Freezing temperature caused damage to cell membrane system and reduced photosynthesis efficiency in L. racemose. To combat the adverse impacts, plasma membrane biosynthesis and antioxidant processes were substantially enhanced. Furthermore, we showed that there was a difference between the responses to freeze-thaw injury in L. racemose from different locations. It may provide new clues to the different genetic background between varieties of L. racemose. These novel findings could provide biochemical and genetic basis for the cultivation and restoration of L. racemose.

Project description:Gene expression changes in human populations exposed to chronic low level radiation have important implications. There are few areas around the world where human population is exposed to elevated levels of natural background radiation. The high level natural radiation areas (HLNRAs) of Kerala coast in south west India is unique for its wide variation in the background radiation dose (<1.0mGy to 45mGy/year). The areas with a background radiation dose of ≤ 1.5mGy/year are considered as normal level natural radiation areas (NLNRA), whereas areas with > 1.5mGy/year are considered as HLNRA. We used microarray analysis to find out global changes in gene expression in peripheral blood mononuclear cells (PBMCs) of individuals belonging to different HLNRA groups as compared to individuals from normal level natural radiation areas (NLNRA).
Project description:To study the responses of microbial communities to short-term nitrogen addition and warming,here we examine microbial communities in mangrove sediments subjected to a 4-months experimental simulation of eutrophication with 185 g m-2 year-1 nitrogen addition (N), 3oC warming (W) and nitrogen addition*warming interaction (NW).
Project description:we used high-throughput Illumina Genome Analyzer IIx (GAIIx) technology to sequence the small RNA transcriptomes of the mangrove species, Avicennia marina. Based on sequence similarity or the secondary structure of precursors, we have identified 193 conserved miRNAs and 26 novel miRNAs in the small RNA transcriptome of Avicennia marina. 1 sample
Project description:In this study two Viperidae species, living in two different habitats, the horned desert viper (Cerastes cerastes) native to the deserts in North Africa and in turn the mangrove pit viper (Cryptelytrops purpureomaculatus), which can be found in South/Southeast Asia, were studied in terms of the identification of the venom proteome.
