Transcription profiling of Arabidopsis thaliana AP1::AtIPT4 transformants vs wild type plants to identify the candidate genes responsive to cytokinin

ABSTRACT: The aim of this experiment is to identify the candidate genes responsive to cytokinin in Arabidopsis floral development. For this purpose, AtIPT4 gene under the control of the AP1 promoter was transformed into wild type plants of Arabidopsis. The transcriptional profiles of the young inflorescence of AP1::AtIPT4 transformants and wild-type plants are compared.

Gene 20100101 1-2

Cytokinin is an essential regulator of numerous plant growth and developmental processes. However, less is known about the mechanisms of cytokinin-regulated floral development. In the present study, we found that flower-specific elevation of cytokinin through transgenic expression of an Arabidopsis ATP/ADP isopentenyltransferase 4 (AtIPT4) gene under the control of the APETALA1 (AP1) promoter lead to floral developmental alterations. These changes included promotion of the number of flowers and ...[more]

ABNORMAL POLLEN 1 (AP1) encodes a legume-type lectin receptor-like kinase and is involved in starch accumulation during rice pollen maturation

Project description:Starch accumulation is the key progress for the maturity of rice pollen grains. However, the regulatory mechanism underlying which remains less understood. Here, we isolated a rice male-sterile mutant ap1, which produces non-viable pollen grains with defective starch accumulation. Functional analysis revealed that AP1 encodes an active L-type lectin receptor-like kinase (L-LecRLK). AP1 is located on plasma membrane and its transcript is highly accumulated in pollen during the starch synthesis phase. RNA-seq analysis suggests that the mutation of AP1 significantly altered the expression of numerous genes involved in starch and sucrose metabolic pathway. Phosphoproteomic profiling revealed that the phosphorylation levels of several proteins within this pathway were significantly downregulated in the mutant. Among which, a rice UDP-glucose pyrophosphorylase (OsUGP2), which roles in pollen starch accumulation, was identified. Further protein–protein interaction assays suggest that OsUGP2 is a feasible target of AP1 to regulate pollen starch accumulation. Our findings thus revealed a novel role of L-LecRLK in controlling pollen maturity via modulating starch metabolism.

Meyerowitz Lab Arabidopsis Operon Array v4 - 4000B scanner - AP1-GR ap1cal inflorescences - time series (hours)

Project description:This experiment describes gene expression after the activation of APETALA1-GR, to study and identify AP1 target genes. We used a 35S:AP1-GR ap1 cal line to induce a synchronized response activating the AP1-GR fusion protein in ap1 cal inflorescence-like meristems through dexamethasone treatment. Tissue samples were collected immediately after the treatment, as well as subsequent timepoints. The expression profiles of the individual samples were then analyzed by gene expression profiling using whole-genome oligonucleotide arrays (non-commercial; Meyerowitz Lab Arabidopsis Operon Array v4). Keywords: time course

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 Arabidopsis exposed to red light illumination with and without lincomycin

Project description:To identify putative regulatory elements enriched in the promoters of target genes of the PGE-dependent retrograde signaling pathway, we analyzed 500 bp regions of sequence upstream of genes whose expression was down-regulated by lincomycin. We treated dark-grown Arabidopsis seedlings with lincomycin, sampled them before or after a short illumination and examined the genomic response using Affymetrix ATH1 oligonucleotide microarrays. Differentially regulated genes were ranked based on descending degree of significance (p-value) and the top 50 genes affected by lincomycin in dark grown seedlings and top 50 genes affected by the antibiotic after illumination were selected for further analysis. Experiment Overall Design: 2*2 factorial design, two variables are (1) with/without lincomycin treatment (2) with/without red illumination. There are 2 replicates for each condition.
