Histone demethylases ELF6 and JMJ13 antagonistically regulate self-fertility in Arabidopsis

ABSTRACT: The chromatin modification H3K27me3 is involved in almost every developmental stage in Arabidopsis. Much remains unknown about the dynamic regulation of this histone modification in flower development and control of self-fertility. Here we demonstrate that the H3K27me3-specific demethylases ELF6 and JMJ13 antagonistically regulate carpel and stamen growth and thus modulate self-fertility. Transcriptome and epigenome data are used to identify potential targets of ELF6 and JMJ13 responsible for these physiological functions. We find that ELF6 relieves expansin genes of epigenetic silencing to promote cell elongation in the carpel, enhancing carpel growth and therefore encouraging out-crossing. On the other hand, JMJ13 activates genes of the jasmonic acid regulatory network alongside the auxin responsive SAUR26, to inhibit carpel growth, enhance stamen growth, and overall promote self-pollination. Our evidence provides novel mechanisms of self-fertility regulation in A.thaliana demonstrating how chromatin modifying enzymes govern the equilibrium between flower self-pollination and out-crossing.

Expression data from Andromonoecious poplar flower

Project description:Exceptionally andromonoecious individuals that flowers appeared to form that structure resembling a carpel attached to the reverse side of stamen cup were detected in strictly dioecious poplar. Andromonoecious poplarswere used to analyze transcript levels accurately. We used microarrays to detail the global programme of gene expression during flower development and identified distinct classes of different-regulated genes between sexes during this process.

An RNA-seq transcriptome analysis of floral buds of an interspecific Brassica hybrid between B. carinata and B. napus

Project description:Using the Illumina HiSeq 2000 platform, 39,598; 32,403and 42,208 genes were identified in flower buds of B. carinata cv.W29, B. napus cv. Zhongshuang 11 and their hybrids, respectively. The differentially expressed genes (DEGs) were significantly enriched in pollen wall assembly, pollen exine formation, pollen development, pollen tube growth, pollination, gene transcription, macromolecule methylation and translation, which might be associated with impaired fertility in the F1 hybrid. These results will shed light on the mechanisms underlying the low fertility of the interspecific hybrids and expand our knowledge of interspecific hybridization.

Transcript profiling of Arabidopsis epiF3 plants

Project description:Arabidopsis msh1 mutants display developmental reprogramming (dr) phenotypes, include reduction in growth, enhanced branching, and delayed maturation and flowering time. MSH1-epi lines were derived by crossing msh1 lines with Col-0 wild type, followed by selection for homozygous MSH1/MSH1 F2 plants and serial self-pollination. MSH1-epiF3 plants displayed phenotypic variation in plant growth, showing enhanced growth, larger rosette diameter, thicker floral stems and earlier flowering time. We carried bisulfite sequencing and uncover the methylome changes accompany the heritable MSH1-epi phenotypes that condition dramatic variation in plant growth.

Genome-wide gene expression of rice cultivar Gui-630 (Indica) X Taiwanjing (Japonica) and mutant lemmata (lem) panicle

Project description:The lem mutant was discovered in a doubled haploid (DH) line derived from the F1 of Gui-630 (Indica)xTaiwanjing (Japonica) by anther culture. The lem mutant did not affect other traits but caused all other floral organs (including palea, lodicule, stamen and carpel) to homeotically transform into lemma or lemma-like structures and caused floral meristem to be indeterminate, thus resulting in the mutant floret consisting of whorls of lemma and lemma-like organs. To identify the global gene expression changes mediated by LEM, we used 57K Affymetrix rice whole genome array to investigate the differences of genome-wide transcriptome between the young panicles of mutant lem versus WT samples during flower development stage. Keywords: rice (Oryza sativa L.),wild-type and lemmata mutant
