Project description:Transcriptome analysis of tomato fruits under heat stress revealed that most SlCRK genes were downregulated upon heat treatment. GO enrichment analysis of genes that were co-expressed with SlCRK members have identified various stress response related and proteasoma protein catabolic process related genes, which may be involved in heat stress signaling Overall, our results provide valuable information for further research on the roles of SlCRKs in response to abiotic stress, especially heat stress.

Project description:Background: Heat stress triggers an evolutionarily conserved set of responses in cells. The transcriptome responds to hyperthermia by altering expression of genes to adapt the cell or organism to survive the heat challenge. RNA-seq technology allows rapid identification of environmentally responsive genes on a large scale. In this study, we have used RNA -seq to identify heat stress responsive genes in the chicken male white-leghorn hepat ocellular (LMH) cell line. Result: The transcripts of 812 genes were responsive to heat stress (p <0.01) with 235 genes up- regulated and 577 down-regulated following 2.5 hours of heat stress. Among the up- regulated were genes whose products function as chaperones, along with genes aff ecting collagen synthesis and deposition, transcription factors, chromatin remodelers and genes modulating the WNT and TGF-beta pathways. Predominant among the down-regulated genes were ones that affect DNA replication and repair along with chromosom al segregation. Many of the genes identified in this study have not been previously implicated in the heat stress response. Conclusion: These data extend our understanding of the transcriptome response to heat stress. Many of the identified biological processes and pathways likely function in adapting cells and organisms to hyperthermic stress. This study may provide important guides to future efforts attempting to improve species abilities to withstand heat stress through genome wide association studies and breeding. In addition, the genes down regulated by heat stress may provide important targets for improving hyperthemic treatment in cancer patients.

Project description:Sequencing of 24 small RNA libraries produced 55.2M reads while 404M reads were obtained from the corresponding 24 PARE libraries. From these, 202 miRNAs were ascertained, of which mature miRNA evidence was obtained for 104 and 36 were found to be differentially expressed after heat stress. The PARE analysis identified 589 transcripts targeted by 84 of the ascertained miRNAs. PARE sequencing validated the targets of the conserved members of miRNA156, miR166 and miR393 families as squamosa promoter-binding-like, homeobox leucine-zipper and transport inhibitor responsive proteins, respectively. Heat stress responsive miRNA targeted superoxide dismutases and an array of homeobox leucine-zipper proteins, F-box proteins and protein kinases. Query of miRNA targets to interactome databases revealed a predominant association of stress responses such as signalling, antioxidant activity and ubiquitination to superoxide dismutases, F-box proteins, pentatricopeptide repeat-containing proteins and mitochondrial transcription termination factor-like proteins.

Project description:The expression of heat-shock proteins (Hsps) induced by a non-lethal heat treatment confers acquired thermotolerance (AT) to organisms against a subsequent challenge of otherwise lethal temperature. After stress signal lifted, AT gradually decayed with the decline of Hsps during recovery period. The duration of AT may be critical for sessile organisms, such as plants, to survive repeated heat stress in the environment. To identify heat-induced genes involved in duration of AT, we took a reverse-genetics approach by screening for Arabidopsis T-DNA insertion mutants that show decreased thermotolerance after a long recovery at non-stress condition following a conditioning treatment. Among the tested mutants corresponding to 47 genes, only the HsfA2 knockout mutant showed significant phenotype. The mutant plants were more sensitive to severe heat stress than the wild type after long but not short recovery following a pretreatment at 37oC, which can be complemented by introducing a wild-type copy of the gene. Quantitative hypocotyl elongation assay also revealed that AT decayed faster in the absence of HsfA2. Significant decline of the transcript levels of several highly heat-induced genes was observed in the HsfA2 knockout plants after a 4-h recovery or after 2 h of prolonged heat stress. Immunoblot anlysis showed that Hsa32 and class I small Hsp were lower in the mutant than in the wild type after a long recovery. Our results suggest that HsfA2 as a heat-induced transactivator sustains the post-stress expression of Hsp genes and extends the duration of AT in Arabidopsis. Keywords: heat shock response
