Project description:au07-13_sqe1 - sqe1 - Arabidopsis transcriptome microarray from wild type and mutant plants. - Arabidopsis microarray from Ler ecotype and the sqe-1 mutant. Keywords: gene knock out
Project description:RNA-sequencing performed on petals and inflorescence of Arabidopsis plants. The study provides insight into the role of the TCP5 transcription factor and its molecular mechanism underlying petal growth, using knock-out, overexpression and induction lines on which RNA-sequencing was performed.
Project description:rs07-04_mips - atmips mutant/photoperiod - In Arabidopsis thaliana, how does MIPS knock out influence gene expression? In AtMIPS mutants how does photoperiod influence gene expression. - Wild type Colombia and MIPS mutant (Salk 023626) plants are grown in short days (8h light) during 27 days and then transfered in long days (16h light) during 4 days. J4JC correspond to 27+4=31 days plants in short days. Keywords: gene knock out
Project description:HSC70 is the cytosolic isoform of plant HSP70. We have found that HSC70 family proteins bind to the heat shock transcription factor A1s (HsfA1s), which are the master regulators of the heat shock response in plants, and suppress their activity. We additionally found that the triple knock out of HSC70s alters responses of Arabidopsis plants to salt stress. To investigate the role of the HSC70s in salt stress responses, we evaluated the effects of the triple knock out on the transcriptome under salt stress.
Project description:Arabidopsis nudix hydrolase 7 knock-out mutant Atnudt7-1 exhibits a reduced size phenotype when compared with age-matched Col-0 wildtype plants growing in potting mix of 12 parts vermiculite: 3 parts redi-earth and 1 part sand. In these array experiments the differences in gene expression caused by this mutation is assessed in comparison to wildtype plants.
Project description:The protein kinase OXI1 is induced by a large number of stress conditions and regulates the interaction of plants with pathogenic and beneficial microbes but little is yet known on the underlying mechanisms. In this work, we generated Arabidopsis OXI1 knock out and overexpression lines and show by transcriptome, proteome and metabolome analysis. Our work revealed that OXI1 regulates biosynthesis of SA via CBP60g-induced expression of isochorismate synthase SID2. OXI1 also induces the transcription factor WRKY33 and its downstream target PAD3, resulting in accumulation of camalexin. Moreover, OXI1 regulates ALD1, SARD4 and FMO1 to promote the biosynthesis of pipecolic acid (Pip) and N-hydroxy pipecolic acid (NHP), mediating systemic acquired resistance to bacterial infection. In contrast to OXI1 overexpressor plants, OXI1 knock out plants show enhanced expression of nuclear and chloroplast genes of photosynthesis, and accordingly enhanced growth under ambient conditions. Overall, these results show that OXI1 plays a key role in regulating the trade-off between growth and defense in plants.
Project description:CaGAL102 is a sequence homolog of Rmlb. In Candida knock out of this gene causes abnormal hyphal morphogenesis and increased sensitivity to cell wall damaging agents. The knock out strain is also avirulent in mouse model of systemic infection. To get a larger insight into the function of the protein product of this gene we carried out global transcription analysis through micro array experiment. The gene is expressed under normal growth conditions and the knock out causes the cells to become hyphal under these conditions. Many of the cell wall proteins were upregulated recapitulating the cell morphology. Keywords: Candida albicans, Gene knockout, genome wide transcription profiling study
