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

ABSTRACT: 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.

Evolutionary divergence of LFY function in the mustards Arabidopsis thaliana and Leavenworthia crassa.

Plant molecular biology 20060817 1-2

LEAFY (LFY), a transcription factor involved in the regulation of flower development in Arabidopsis thaliana, has been identified as a candidate gene in the diversification of plant architecture in Brassicaceae. Previous research with Leavenworthia crassa, which produces solitary flowers in the axils of rosette leaves, has shown that the L. crassa LFY ortholog, LcrLFY, rescues most aspects of flower development in A. thaliana but showed two novel traits: flowers produced additional petals and in ...[more]

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.
