Project description:To identify genes that co-express with rice cellulose synthase genes involved in rice secondary cell wall formation, transcriptome analyses was performed using rice internodesbefore and after the heading stage, where secondary cell wall formation extensively occur.

Project description:We compared the transcriptome of homozygous mutants for AtCesA4 and AtCesA6 (cellulose synthase genes) to their heterozygous counterparts that have a wild type phenotype. All plants were 4-weeks-old and grown under short day conditions.

Project description:Transcriptional profiling after inhibition of cellulose synthesis by thaxtomin A and isoxaben in Arabidopsis thaliana suspension cells Perturbations in the cellulose content of the plant cell wall lead to global modifications in cellular homeostasis, as seen in cellulose synthase mutants or after inhibiting cellulose synthesis. In particular, application of inhibitors of cellulose synthesis such as thaxtomin A (TA) and isoxaben (IXB) initiates a programmed cell death (PCD) in Arabidopsis thaliana suspension cells that is dependent on de novo gene transcription. To further understand how TA and IXB activate PCD, a whole genome microarray analysis was performed on mRNA isolated from Arabidopsis suspension cells exposed to TA and IXB. More than 75% of the genes upregulated by TA were also upregulated by IXB, including genes encoding cell wall-related and calcium-binding proteins, defence/stress-related transcription factors, signalling components and cell death-related proteins. Comparisons with published transcriptional analyses revealed an important subset of genes generally induced in response to various biotic and abiotic stress.

Project description:The barley brittle stem mutants, fs2, designated X054 and M245, have reduced levels of cellulose compared with their isogenic parents Ohichi and Shiroseto. A custom-designed microarray, based on Agilent technology and including genes involved in cell wall metabolism, was used to compare transcript levels in the mutant and parental lines. For both mutants, the microarray revealed a marked decrease in mRNA for the HvCesA4 cellulose synthase gene in specific zones of stem internodes, and this was confirmed by quantitative PCR.

Project description:The interplay between plant chemistry and architecture was investigated using a pharmacological approach combined with mutant analysis. Due to the high abundance and essential role of cellulose in plant development and function, it was hypothesized that perturbation of cellulose biosynthesis would have far-reaching effects on plant chemistry and resource allocation. The impact of cellulose disruption was studied through comprehensive multiphase-NMR (CMP-NMR) using the Arabidopsis thaliana cellulose synthase mutant ectopic lignification1 (eli1). CMP-NMR confirmed several known metabolic impacts of cellulose disruption including increased lignification, increased starch production, and a shift from crystalline to amorphous cellulose. It also revealed unexpected metabolic impacts such as increased methanol production, increased seed-derived lipid content, and the presence of the peptide pentaglycine, which had not been previously observed in plants. It was further hypothesized that the metabolic impacts of cellulose disruption are mediated by one or more signal molecules that would be elevated in cellulose synthase mutants such as eli1. The presence of one or more signal molecules in eli1 that induce a lignification response was confirmed by exposing wild-type seedlings to ground tissue from eli1. Treatment of wild-type seedlings with pentaglycine suggested that the peptide may be at least partially responsible for mediating this response. A case is made for glycine rich proteins (GRPs) as the source of pentaglycine in vivo, and for wall associated kinases (WAKs) as receptors that trigger either developmental or defence responses through differential binding of intact GRPs and oligoglycine peptides.

Project description:We compared the transcriptome of homozygous mutants for AtCesA4 and AtCesA6 (cellulose synthase genes) to their heterozygous counterparts that have a wild type phenotype. All plants were 4-weeks-old and grown under short day conditions. 10 samples were used in this experiment: 3 each homozygous and heterozygous AtCesA4 plants, and 2 each homozygous and heterozygous AtCesA6 plants.

Project description:Salt stress is one of the most detrimental abiotic stresses for plants. The plant cell wall, which encases plant cells and functions as a cellular exoskeleton, is an important structure to cope with such stresses. One of the main components of the cell wall is cellulose, which is synthesized by cellulose synthase (CESA) complexes (CSC) at the plasma membrane by moving along underlying cortical microtubules. COMPANION OF CELLULOSE SYNTHASE (CC) 1 and 2 have been identified to be components of the CSCs, and function in maintaining cellulose synthesis under salt stress by supporting microtubules and CESA behaviors. However, the exact regulatory mechanisms of the CC1 and CC2 proteins remain largely unknown. In this project, we did an immunoprecipitation-mass spectrometry (IP-MS) analysis to identify potential interactors of CC1 for further study.

Genes expression was measured for the upper and lower zones from the 4th internodes of stems. Plant were at Zadocks developmental stage 49. Gene expression was compared between mutants and their wildtype parents.
