Transcription profiling by array of Arabidopsis with different genotypes for flowering locus C and frigida after flowering induction

ABSTRACT: Plants of three different genotypes (FRI FLC, FRI flc and fri flc) were induced to flowering by shifting from short day conditions to long day conditions. FRI=FRIGIDA, FLC=FLOWERING LOCUS C.

Although multiple environmental cues regulate the transition to flowering in Arabidopsis thaliana, previous studies have suggested that wild A. thaliana accessions fall primarily into two classes, distinguished by their requirement for vernalization (extended winter-like temperatures), which enables rapid flowering under long days. Much of the difference in vernalization response is apparently due to variation at two epistatically acting loci, FRI and FLC. We present the response of over 150 wil ...[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 of potent induction of flowering in A. thaliana by elevated temperature

Project description:Plants were grown on soil for 35 days under short day conditions (8hrs light/16hrs dark) at 16¡ÄC and 65% relative humidity. Flowering was induced by shifting either to long day conditions (16/8) at 16¡ÄC and 65% relative humidity or to 25¨¬C in short days (8/16). Samples were taken at day 0, 2, 5 and 9 after shifting.

Transcription profiling by array of Arabidopsis thaliana roots following the photoperiodic induction of flowering

Project description:The induction of flowering by the photoperiodic pathway (i.e. an increase in daylength) involves the production of systemic signals that induce the transition to reproductive development. In order to evaluate the early events occurring in the roots during the photoperiodic induction of flowering, we harvested the roots of 7 week-old Col-0 Arabidopsis thaliana plants grown plants exposed to a single 22-hour long day. Control plants were maintained under 8-hour short days. Plants were grown in hydroponics and roots tissues were harvested 16 and 22 hours after the beginning of the light period.
