Project description:Differential expression was determined in Calu-3 cells between mock infected and infection with NS1trunc124: A/Vietnam/1203-CIP048_RG4/2004 (H5N1) or WT: A/Vietnam/1203/2004 (H5N1) at different times post infection.

Nontarget-site resistance due to rapid physiological response in 2,4-D resistant Conyza sumatrensis: Reduced 2,4-D translocation and auxin-induced gene expression

Project description:We used RNAseq to quantify trascript expression from three populations of Conyza sumatrensis before and 5 hours after treatment with 2,4-D. This study investigates different responses between a 2,4-D resistant biotype compared to a 2,4-D sensitive biotype.

Transcriptomic analysis of PLA-degrading bacteria Brevibacillus brevis grown on polylactic acid

Project description:Polylactic acid (PLA) is a promising biodegradable material used in various fields, such as mulching films and disposable packaging materials. Biological approaches for completely degrading biodegradable polymers can provide environmentally friendly solutions. However, to our knowledge, no studies have performed transcriptome profiling to analyze PLA-degrading genes of PLA-degrading bacteria. Therefore, this study reports for the first time an RNA sequence approach for tracing genes involved in PLA biodegradation in the PLA-degrading bacterium Brevibacillus brevis. In the interpretation results of the differentially expressed genes, the hydrolase genes mhqD and nap and the serine protease gene besA were up-regulated by a fold change of 7.97, 4.89, and 4.09, respectively. This result suggests that hydrolases play a key role in PLA biodegradation by B. brevis. In addition, Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses showed that genes implicated in biofilm formation were upregulated. The biodegradation of PLA starts with bacteria attaching to the surface of PLA and forming a biofilm. Therefore, it could be confirmed that the above genes were up-regulated for access to PLA and biodegradation. Our results provide transcriptome-based insights into PLA biodegradation, which pitch a better understanding of microbial biodegradation of plastics.

Gene expression profile of leaf in rice grown under paddy field with macronutrient deficiencies

Project description:Macronutrients are pivotal elements for proper plant growth and development. We performed microarray analysis of rice leaves under nitrogen (N), phosphorus (P), and potassium (K) deficiency conditions in paddy field to obtain a global view of gene regulations associated with plant response to essential nutrients.

Insights into ROS-dependent signalling underlying transcriptomic plant responses to the herbicide 2,4-D

Project description:The synthetic auxin 2,4-dichlorophenoxyacetic acid (2,4-D) functions as an agronomic weed control herbicide. High concentrations of 2,4-D induce plant growth defects, particularly leaf epinasty and stem curvature. Although the 2,4-D phenotype is associated with ROS production, little is known about ROS-dependent signalling. In this study, by using T-DNA Arabidopsis mutants to silence peroxisomal acyl CoA oxidase 1 (acx1-2), we identified ACX1 as one of the main sources of ROS production and as partly the cause of the epinasty phenotype following the application of 2,4-D. Transcriptomic analyses of WT plants after treatment with 2,4-D revealed a ROS-related peroxisomal footprint in early plant responses, while other organelles, such as mitochondria and chloroplasts, are involved in later responses. Interestingly, a group of ACX1-dependent transcripts in plant responses to 2,4-D, previously associated with epinasty, is related to auxin biosynthesis, metabolism and signalling. We found that protein AUXIN SIGNALING F-BOX 3 (AFB3), a component of SCF (ASK-cullin-F-box) E3 ubiquitin ligase complexes, which functions as an auxin receptor and mediates Aux/IAA proteasomal degradation, acts downstream of ACX1 and is involved in the epinasty phenotype induced by 2,4-D. We also found that protein degradation associated with ubiquitin E3-RING and E3-SCF-FBOX in ACX1-dependent signalling in plant responses to 2,4-D is significantly regulated over longer treatment periods.
