Project description:Mangrove plants are the demonstrated woody plants in tropical and subtropical coastal area with great ecological and economic importance. However, due to the extreme global climate change and increased human activities, mangroves is suffering a dramatic declining worldwide. Lumnitzera littorea (Jack) Voigt is one of the most endangered mangrove species in China. A comprehensive understanding on its resistance mechanisms to low ambient temperature help us to better conserve and restore L. littorea. In the current study, we performed comparative transcriptome analysis to investigate the genome-wide changes of gene expression profile in L. littorea under chilling stress (8°C day/5°C night) over normal condition (25°C day/23°C night). The low temperature suppressed fatty acid elongation and protein phosphorylation in L. littorea, while induced calcium ion binding process and signaling transduction, suggesting an activation of cold-stress sensing and signaling in L. littorea. Combining our analysis with our previous physiological assays, we showed a substantial photoinhibition occurring in the seedlings of L. littorea with the decrease of ambient temperature, and the synthesis of photosystem II reaction center protein D1 and peroxidase-involved scavenging of reactive oxygen species (ROS) were enhanced accordingly to combat the adverse impacts. Finally, we highlighted the biological significance of post-transcriptional regulation, including RNA binding and surveillance, in coping with cold stress in L. littorea. Collectively, our findings provide a global view to the resistance mechanisms of chilling stress in L. littorea, and valuable genetic resources to assist the protection and restoration of L. littorea.

Project description:Identification of bacteria isolated from healthy corals in the Great Barrier Reef
| PRJNA485194 | ENA
Project description:The Crown-of-Thorns starfish (COTS), Acanthaster planci, is a highly fecund predator of reef-building corals distributed throughout the Indo-Pacific. COTS population outbreaks cause substantial loss of coral cover, diminishing the integrity and resilience of the reef ecosystems thus increasing their susceptibility to climate change. We sequenced genomes of A. planci from the Great Barrier Reef, Australia (GBR) and Okinawa, Japan (OKI) to guide identification of species-specific peptide communication with potential applications in mitigation strategies. The genome-encoded proteins excreted and secreted into the surrounding seawater by COTS forming aggregations and by those escaping the predatory giant triton snail, Charonia tritonis, were identified LC-MS/MS.

Project description:The Crown-of-thorns starfish (COTS) Acanthaster planci feeds on hard corals and its outbreaks are a major cause of destruction of coral communities on the Australian Great Barrier Reef. Whilst population booms and the social behaviour of COTS have been well studied, little is known about the neural mechanisms underlying COTS metabolism and behaviour. One of the major classes of chemical messengers that regulate metabolic and behavioural processes in animals are neuropeptides. Here, we have analysed COTS genome and transcriptome sequence data to identify neuropeptide precursor proteins in this species. Mass spectrometry was employed to identify neuropeptides extracted from radial nerve cords. Forty-nine neuropeptide precursors were identified, including homologs of neuropeptide signaling systems that are evolutionarily conserved throughout the Bilateria.

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.
