Catma1-bou-bou mutant characterisation: Autotrophic growth acquisition in the ABOUTDESOUFFLE (bou) mutant

ABSTRACT: rs07-09_bou - catma1-bou - Autotrophic growth acquisition is abolished in the bou mutant in Arabidopsis thaliana. BOU encodes a putative mitochondrial acyl carnitine carrier. bou mutant is blocked at the cotyledon stage. Autotrophic growth of the bou mutant can be achieved with addition of sugar in the medium or in darkness. Moreover, BOU gene expression is activated by light and depends on plant developmental stage. We wish to determine what are the consequences of bou gene mutation at the transcriptome level. We wish to understand whether bou growth arrest is due to the modification of specific genes expression or to a general effect on metabolism at the transition from heterotrophic to autotrophic growth. - Seeds from a heterozygous plants were grown for either 5 or 8 days after germination on synthetic medium (MS/2) without sugar under continuous light. We harvested cotyledon-stage blocked plants (bou phenotype) from three independent Petri dishes and also green seedlings with true leaves and fully developed root (heterozygotes with a wild-type phenotype) . We also grew independently Col-O plants for 5 and 8 days to compare them with the bou mutants. Keywords: gene knock in (transgenic),normal vs disease comparison,time course

Proteome Analysis of rapeseed Cotyledons to Light

Project description:Among multiple factors, light plays a decisive role in the switch from heterotrophic to autotrophic growth. Under dark condition, the rapeseed hypocotyl extended quickly with an apical hook, yellow and folded cotyledon, and the glyoxysome assembling. Whereas under light, the hypocotyl extended slowly, the cotyledon unfolded and turned green. In this study, we performed proteome profiling analyses to show the differential molecular responses of Brassica napus cotyledons to light and dark and reveal metabolic adaptations in postgerminative seedling establishment. In both light and dark-grown conditions.

Expression data from Arabidopsis wild-type, sicy-192, and sicy-192 gun1-101 plants

Project description:Plastid gene expression (PGE) acts as a signal that regulates the expression of photosynthesis-associated nuclear genes (PhANGs) via GENOMES UNCOUPLED1 (GUN1)-dependent retrograde signaling. We recently isolated Arabidopsis sugar-inducible cotyledon yellow-192 (sicy-192), a gain-of-function mutant of plastidic invertase (INV-E), and showed that following the treatment of this mutant with sucrose, the expression of PhANGs decreased while that of nitrate reductase 1 (NIA1) increased. Plastid-encoded RNA polymerase (PEP)-dependent PGE was markedly suppressed in the sicy-192 mutant by the sucrose treatment. A double mutant of sicy-192 and gun1-101, a null mutant of GUN1, revealed that metabolic perturbation in the sucrose-treated sicy-192 mutant was, at least in part, dependent on GUN1. To confirm whether there is a relationship between plastid sugar metabolism and nuclear gene expression, we performed a microarray analysis using Suc-treated 3 genotypes consisting of wild-type, sicy-192, and sicy-192 gun1-101 plants. Wild-type, sicy-192, and sicy-192 gun1-101 plants were grown on MS medium containing 100 mM sucrose in a growth chamber kept at 25Â°C during 16 h of light (100 Âµmol/m2/s) and at 22Â°C during 8 h of darkness for 4 days. At 4 days of age, cotyledons were collected as samples for microarray analysis.

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

Transcription profiling of wild type, mur4 knock-out and prl1 knock-out Arabidopsis plants grown in media with 1% glucose

Project description:Sugars such as glucose function as signal molecules that regulate gene expression, growth and development in plants, animals and yeast. To understand the molecular mechanisms of sugar responses, we isolated and characterized an Arabidopsis thaliana mutant, high sugar- response 8 (hsr8), which enhances sugar responsive growth and gene expression. Light- grown hsr8 plants exhibited increased starch and anthocyanin and reduced chlorophyll content in response to glucose treatment. Dark- grown hsr8 seedlings show glucose- hypersensitive hypocotyl elongation and development. The HSR8 gene, isolated using map-based cloning, is allelic to the MUR4 gene involved in arabinose synthesis. Dark- grown mur1 and mur3 seedlings also exhibit similar sugar responses to hsr8/mur4. The sugar- hypersensitive phenotypes of hsr8/mur4, mur1 and mur3 were restored to those of WT by boric acid, suggesting that alterations in the cell wall cause hypersensitive sugar- responsive phenotypes. Genetic analysis showed that sugar- hypersensitive responses in hsr8 mutants were suppressed by prl1, indicating that nuclear-localised PRL1 is required for enhanced sugar-responses in hsr8 mutant plants. Microarray analysis revealed that expression of many cell wall-related and sugar-responsive genes was altered in mur4-1, and expression of a significant proportion of these genes was restored to wild type levels in the mur4-1prl1 double mutant. These findings reveal a pathway that signals changes in the cell wall through PRL1 to altered gene expression and sugar- responsive metabolic, growth and developmental changes. The experiments submitted here are conducted on 6d-old seedlings grown on medium containning 1% glucose in dark.

Transcript profiling in Arabidopsis gollum mutant: Role of the Gollum gene in the plant development

Project description:rs07-08_gollum - trancript profiling in arabidopsis gollum mutant. Elucidate the role of Gollum gene in the plant development by a RNAi approach. Seeds of WT and RNAi lines were sowed on soil and conserved 2 days at 4°C. The pots were transferred to the greenhouse under long-day conditions (16h light, 22°C). The leaves of one-month old plants were harvested and total RNA were extracted. Keywords: wt vs mutant comparison

Arabidopsis thaliana wild-type vs. cotyledon-less laterne (= pid enp homozygous) mutant

Project description:Transcriptional profiling of cotyledon transcriptomics at the seedling stage (6 d) by comparison of wild-type vs. cotyledon-less laterne (= pid enp) homozygous mutant. The goal was to determine the transcriptomic profile of a cotyledon. The experiment took advantage of the endogenously caused lack of cotyledons instead of dissecting these organs, which would cause wound-induced expression.This was achieved by comparing seedlings of the Arabidopsis thaliana pid enp double mutant, which is incapable to generate cotyledons. This is caused by the loss of apical cell polarisation of the auxin efflux carrier PIN1 in epidermal cells during embryogenesis.
