Project description:Methyl CpG Binding (MBD) proteins are a class of protein that binds with methylated DNA. In the model plant Arabidopsis thaliana there are 13 MBD proteins are there. To understand the gene regulation we performed microarray analysis of mutants of three genes (atmbd4, atmbd6 and atmbd11). Ten day old seedlings of these three mutant were compared with the wild type plants grown in same condition.
Project description:We sequenced the poly(A)+ and poly(A)- samples of the roots and shoots from 10-day-old WT seedlings grown under P+ and P- condition. The WT plant refers to Columbia ecotype Arabidopsis seedlings. Each condition has two replicates. After total RNA extraction, ribosomal RNAs were removed using RiboMinus™ Plant Kit repeated two times. The poly(A)+ and poly(A)- constituent were separated with oligo(dT) magnetic beads (Oligotex mRNA Mini Kit, QIAGEN). Using a 2-fold change and a P-value <0.05 as the cut-off for selecting the differentially expressed transcripts, we globally identified novel noncoding lncRNAs.
Project description:With the information gathered through mass-shift- and correlation-analysis, we predict PPi on a proteomic scale and describe the results in form of a network. This experiment was done with 3 week old Arabidopsis thaliana wt seedlings grown in hydroponic culture (1/2 MS-Medium)
Project description:Arabidopsis ult1-3 mutant was shown to rescue the phenotype of LFYasEMF1 to that of WT. We performed microarray analysis of 7-d-old and 15-d-old seedlings of WT, LFYasEMF1, ult1-3 and LFYasEMF1/ult1-3 grown under short day to study the underlie mechanism of this phenotypic rescuing. Gene expression of 7 and 15 day old WT, LFYasEMF1, ult1-3 and LFYasEMF1/ult1-3 seedlings grown under short day condition were performed and compared.
Project description:au14-03_bigun - bigun transcriptomics - What are the gene networks associated with BIGUN function during Hyaloperonospora arabidopsidis infection? - 5 weeks after germination of 12 seedlings of Arabidopsis thaliana Col-0,bigun 1 mutant and bigun 2 mutant genotypes(growth condition n°1),6 plants are infected by spraying a solution of Hyaloperonospora arabidopsidis spores,and 6 plants are left untreated,and all plants were cultivated under growth condition n°2.For each condition,leaves were sampled and pooled one week after infection.The experiment was repeated three times.
Project description:Arabidopsis ult1-3 mutant was shown to rescue the phenotype of LFYasEMF1 to that of WT. We performed microarray analysis of 7-d-old and 15-d-old seedlings of WT, LFYasEMF1, ult1-3 and LFYasEMF1/ult1-3 grown under short day to study the underlie mechanism of this phenotypic rescuing.
Project description:Plant roots located in the upper soil layers are prone to experience high temperatures. To gain insight into the effect of high temperature on root development and functioning, we exposed five-day-old Arabidopsis thaliana seedlings grown on agar plates to 30 °C for 48 hours, and compared the gene expression profile in the root tip with that from seedlings that remained at 22 °C.
Project description:Calcium deficiency response in liverwort, Arabidopsis and lettuce: (1) Marchantia polymorpha: M. polymorpha wildtype and Gβ-null mutant plants (Tak-1, gpb1-2) were grown in control liquid Yamagami media (2 mM Ca) for 6 days. For RNA-seq experiments, 6 day old gemmalings were transferred to calcium deficiency (0 mM Ca) media. Samples were collected at 48 h after the transfer. The transcriptomic profiles were collected from two independent batches. In total four biological replicates were used for each condition and each genotype for a total of 16 samples. (2) Arabidopsis thaliana: For Arabidopsis RNA-seq experiment, 6-day old seedlings grown on ½ strength MS media with sucrose were transferred to Yamagami media with 2 mM or 0 mM CaCl2 and treated for 7 days. (3) Lactuca Sativa: For lettuce RNA-seq, 4-day old seedlings grown on water agar (1%) were transferred to Yamagami media with 2 mM or 0.15 mM CaCl2 and treated for 7 days. In total four and three biological replicates were used for each condition for a total of 8 and 6 samples respectively for Arabidopsis and lettuce.
