Integration of spatial and temporal information during floral induction in Arabidopsis.

Wigge Philip A PA Kim Min Chul MC Jaeger Katja E KE Busch Wolfgang W Schmid Markus M Lohmann Jan U JU Weigel Detlef D

Science (New York, N.Y.) 20050801 5737

Flowering of Arabidopsis is regulated by several environmental and endogenous signals. An important integrator of these inputs is the FLOWERING LOCUS T (FT) gene, which encodes a small, possibly mobile protein. A primary response to floral induction is the activation of FT RNA expression in leaves. Because flowers form at a distant site, the shoot apex, these data suggest that FT primarily controls the timing of flowering. Integration of temporal and spatial information is mediated in part by th ...[more]

Transcription profiling of Arabidopsis thaliana LFY mutant plants transformed with either Arabidopsis LFY or Leanworthia crassa LFY to investigate evolutionary divergence of LFY function

Project description:The aim of this experiment is to test the ability of the ortholog of Arabidopsis LFY gene from Leanworthia crassa (Lcr) to complement an Arabidopsis LFY mutant. Plants used are homozygous lfy6 mutants (EMS alleles) in Ler background which are transformed or not (for the lfy6 mutant) by genomic clones for Arabidopsis LFY (AthLFY) or Leanworthia crassa LFY (LcrLFY). Flowering was synchronized by growing plants in SD then shifting them to LD. 2 time points samples (wild type Ler) were taken at the end of the SD period as a reference for genes induced by shifting to LD, irrespective of the status at the LFY locus.

Transcription profiling of Arabidopsis thaliana LFY mutant plants transformed with different LFY orthologs to investigate evolutionary divergence of LFY function

Project description:The aim of this experiment is to test the ability of the ortholog of Arabidopsis LFY gene from flowering and non flowering species to complement an Arabidopsis LFY mutant. Plants expressing, in a homozygous lfy12 background, the open reading frame of LFY orthologs under the control of Arabidopsis LFY promoter were synchronously induced to flower by growing plants in short days for 30 days then shifting them to Long Day for an additional 8 days. Shoot apices were dissected at either d0 or d8 in long days. Two biological replicates were performed. The following genotypes were used: Col - wild type arabidopsis; reference strain LFY (lfy12; LFY::AthLFY) - Arabidopsis UNI (lfy12; LFY::UNI) - Pisum ALF (lfy12; LFY::ALF) - Petunia WelNDLY (lfy12; LFY::WelNDLY) - Welwitschia mirabilis CrLFY1 (lfy12; LFY::CrLFY1) - Ceratopteris richardii CrLFY2 (lfy12; LFY::CrLFY2) - Ceratopteris richardii lfy-2; weak lfy allele lfy-9; intermediate leafy allele lfy-12; strong leafy allele.

Transcription profiling to investigate the photoperiodic control of starch mobilisation in Arabidopsis thaliana

Project description:In order to identify genes specifically involved in the photoperiodic control of the mobilisation programme for starch reserve in Arabidopsis thaliana transcription profiling was performed on the following genotypes Columbia wild type (Col-0), CO overexpressor (35S::CO), CO muntant (co-10), GBSSI mutant (gbs-1), aps1 mutant (aps1) and Columbia with sucrose. The different Arabidopsis thaliana genotype seedlings were cultivated in long day conditions (16 h day/ 8 h dark) at 22 C in controlled environment cabinets for two weeks. Samples were collected at ZT 4, immediately frozen in liquid nitrogen and processed.

Transcription profiling of Arabidopsis recombinant strains - control hybridizations

Project description:The study of natural genetic variation for plant disease resistance responses is a complementary approach to utilizing mutants to elucidate genetic pathways. While some key genes involved in pathways controlling disease resistance, and signaling intermediates such as salicylic acid (SA) and jasmonic acid (JA), have been identified through mutational analyses, the use of genetic variation in natural populations permits the identification of change-of-function alleles, which likely act in a quantitative manner. Whole genome microarrays, such as Affymetrix GeneChips, allow for molecular characterization of the disease response at a genomics level and characterization of differences in gene expression due to natural variation. Differences in the level of gene expression, or expression level polymorphisms (ELPs), can be mapped in a segregating population to identify regulatory quantitative trait loci (expression QTLs, eQTLs) affecting host resistance responses. We surveyed recombinant inbred lines (RILs) from a population derived from a cross of inbred Arabidopsis accessions Bayreuth-0 (Bay-0) and Shahdara (Sha) in order to map eQTLs controlling ELPs. We treated vegetatively grown plants with either SA or a control solution (Silwet), and harvested the plants 28 hours after chemical treatment. Here we present Affymetrix GeneChip microarray expression data for 8 biological replications of the control (Silwet) samples for Bay-0 and Sha.

We present Affymetrix GeneChip microarray expression data for 2 biological replications of the control (Silwet) samples for 63 RILs, plus replicated Bay-0 and Sha control samples grown at the same time as the RILs. These GeneChips representing 63 RILs, along with the GeneChips in Accession E-TABM-62 which represent an additional 148 RILs, form a 211 RIL dataset from which we mapped eQTLs.

Transcription profiling of Arabidopsis treated with silwet for varying time and high throughout haplotyping and single feature polymorphism markers in Arabidopsis

Differences in the level of gene expression, or expression level polymorphisms (ELPs), can be mapped in a segregating population to identify regulatory quantitative trait loci (expression QTLs, e-QTLs) affecting host resistance responses. We assessed Arabidopsis accessions Bayreuth-0 (Bay-0) and Shahdara (Sha) for natural variation in the response to SA. We treated vegetatively grown plants with either SA or a control solution (Silwet), and harvested the plants 4, 28, or 52 hours after chemical treatment. We present Affymetrix GeneChip microarray expression data for 2 biological replications of the control (Silwet) samples for Bay-0 and Sha. These GeneChips were used to generate genetic markers which allowed the development of high-density haplotype maps of a Bay-0 x Sha RIL population.
