Project description:Global warming and human activities have led to an increased frequency of hypoxia in coastal regions. Hypoxia not only affects the growth and development of scallops but can also cause death, posing a significant challenge to the health and sustainability of aquaculture. Its effects on scallop growth and immune system have been widely reported, but studies on the effects of hypoxic stress on the metabolism of Yesso scallop Mizuhopecten yessoensis are not fully understood. Additionally, the molecular mechanisms of hypoxic stress on damage to the Yesso scallop are still limited. In this study, we deploy high-throughput RNA sequencing (RNA-Seq) and non-targeted liquid chromatography-mass spectrometry (LC-MS) based metabolomics analysis to investigate the alterations in key genes and metabolites in scallops after 24 hours of hypoxia stress (DO: 1 ± 0.1 mg/L). A total of 704 differentially expressed genes (DEGs) and 302 differentially expressed metabolites (DEMs) were identified in the gill tissues of Yesso scallops under hypoxic conditions, respectively. DEGs and DEMs were involved in energy metabolism, antioxidant responses, immune responses, and inflammatory responses, as well as processes of cell apoptosis and cell proliferation. KEGG enrichment analysis shows that the mTOR signaling pathway is a significantly enriched pathway shared by DEGs and DEMs. These findings suggest that Yesso scallops cope with acute hypoxic stress by changing energy metabolism, inhibiting cell apoptosis and proliferation, and increasing immune defense strategies. Overall, the results of this study provide a new understanding of how Yesso scallops respond to hypoxia and provide target genes for the selection and breeding of low-oxygen-tolerant scallops.

Project description:C3-C4 intermediate Moricandia suffruticosa showed tolerance to drought and heat stresses, and high photosynthetic capacity under these abiotic stresses as comparing with C3 relative crop rapeseed (Brassica napus). In our study, systematic analysis was conducted to reveal photosynthetic difference between C3-C4 Moricandia suffruticosa and its relative C3 rapeseed from the same Brassiceae tribe. It was found that Moricandia leaf photosynthesis and anatomy were significantly changed compared to rapeseed under drought and heat stress conditions. De novo transcriptome of Moricandia was assembled by next generation sequencing, and unigenes were mapped to respective rapeseed gene locus. Then comparative transcriptome analysis was conducted in leaf tissues of Moricandia and rapeseed under both drought and heat stresses. Main pathways and candidate genes were revealed from this analysis, which may be associated with the stress induced change in Moricandia.

Project description:Drought and heat are major abiotic stresses frequently coinciding to threaten rice production. Although hundreds of stress-related genes have been identified in the past two decades, very few genes have been confirmed to confer resistance to multiple stresses in crops. Here we report ONAC023, identified through NAC-centered gene regulatory network and genetic association analyses, is a hub stress-regulator that integrates the regulations of both drought and heat tolerance in rice. The loss-of-function mutant of ONAC023 showed significantly increased sensitivity to drought and heat stresses, whereas the overexpression of ONAC023 confers drought and heat tolerance at both seedling and reproductive stages. Notably, drought and heat stresses activated the function of ONAC023 not only by the induction of ONAC023 transcript but also by the nuclear accumulation of ONAC023 protein through a remorin-importin-α-assisted translocation. Under drought or heat stress, ONAC023 can directly target and promote the expression of functionally diverse downstream genes, such as OsPIP2;7, PGL3, OsFKBP20-1b, and OsSF3B1, which are involved in various stress-responsive processes including water transport, reactive oxygen species homeostasis, and alternative splicing (AS). Furthermore, genome-wide AS profiling revealed that the loss of ONAC023 function led to alternation of the encoding outcomes of thousands of AS transcripts under drought and heat stresses. These results manifested that ONAC023 is fine tuned to positively regulate drought and heat tolerance through the integration of multiple stress-responsive processes. Our findings provide not only an underlying connection between drought and heat responses, but also a promising candidate for engineering multi-stress-resilient rice.

We used microarrays to examine the genomic programs of cells incubated under different microenvironments. Experiment Overall Design: HMEC cells were exposed to different environmental stresses and RNAs were extracted and put on Affymetrix microarrays. We gathered RNAs from cells grown in regular media (control), lactic acidosis, hypoxia, the combinatino of lactic acidosis and hypoxia, lactosis, as well as acidosis.

Project description:Biotic and abiotic stresses limit agricultural yields, and plants are often simultaneously exposed to multiple stresses. Combinations of stresses such as heat and drought or cold and high light intensity, have profound effects on crop performance and yeilds To analyze such responses, we initially compared transcriptome changes in ten Arabidopsis thaliana ecotypes using cold, heat, high light, salt and flagellin treatments as single stress factors or their double combinations.
