Intraspecific hybrids between the Arabidopsis thaliana accessions C24 and Landsberg erecta have strong heterosis. The reciprocal hybrids show a decreased level of 24-nt small RNA (sRNA) relative to the parents with the decrease greatest for those loci where the parents had markedly different 24-nt sRNA levels. The genomic regions with reduced 24-nt sRNA levels were largely associated with genes and their flanking regions indicating a potential effect on gene expression. We identified several exa ...[more]

Project description:Hybrids often display increased size and growth, and thus are widely cultivated in agriculture and horticulture. Recent discoveries demonstrating the important regulatory roles of small RNAs have greatly improved our understanding of many basic biological questions, and could illuminate the molecular basis for the enhanced growth and size of hybrid plants. We profiled small RNAs by deep sequencing to characterize the inheritance patterns of small RNA levels in reciprocal hybrids of two Arabidopsis thaliana accessions, Columbia and Landsberg erecta. We find 24-nt siRNAs predominate among those small RNAs that are differentially expressed between the parents. Following hybridization, the transposable element (TE)-derived siRNAs are often inherited in an additive manner, whereas siRNAs associated with protein-coding genes are often down-regulated in hybrids to the levels observed for the parent with lower relative siRNA levels. Among the protein-coding genes that exhibit this pattern, genes that function in pathogen defense, abiotic stress tolerance, and secondary metabolism are significantly enriched. Small RNA clusters from protein-coding genes where a TE is present within one kilobase show a different predominant inheritance pattern (additive) from those that do not (low-parent dominance). Thus, down-regulation in the form of low-parent dominance is likely the default pattern of inheritance for genic siRNA, and a different inheritance mechanism for TE siRNA is suggested.

Project description:F1 hybrids can outperform their parents in yield and vegetative biomass, features of hybrid vigor that form the basis of the hybrid seed industry. The yield advantage of the F1 is lost in the F2 and subsequent generations. In Arabidopsis, from F2 plants that have a F1-like phenotype, we have by recurrent selection produced pure breeding F5/F6 lines, hybrid mimics, in which the characteristics of the F1 hybrid are stabilized. These hybrid mimic lines, like the F1 hybrid, have larger leaves than the parent plant, and the leaves have increased photosynthetic cell numbers, and in some lines, increased size of cells, suggesting an increased supply of photosynthate. A comparison of the differentially expressed genes in the F1 hybrid with those of eight hybrid mimic lines identified metabolic pathways altered in both; these pathways include down-regulation of defense response pathways and altered abiotic response pathways. F6 hybrid mimic lines are mostly homozygous at each locus in the genome and yet retain the large F1-like phenotype. Many alleles in the F6 plants, when they are homozygous, have expression levels different to the level in the parent. We consider this altered expression to be a consequence of transregulation of genes from one parent by genes from the other parent. Transregulation could also arise from epigenetic modifications in the F1. The pure breeding hybrid mimics have been valuable in probing the mechanisms of hybrid vigor and may also prove to be useful hybrid vigor equivalents in agriculture.

Project description:The zygote, a totipotent stem cell, is crucial to the life cycle of sexually reproducing organisms. It is produced by the fusion of two differentiated cells-the egg and sperm, which in plants have radically different siRNA transcriptomes from each other and from multicellular embryos. Owing to technical challenges, the epigenetic changes that accompany the transition from differentiated gametes to totipotent zygote are poorly understood. Because siRNAs serve as both regulators and outputs of the epigenome, we characterized small RNA transcriptomes of zygotes from rice. Zygote small RNAs exhibit extensive maternal carryover and an apparent lack of paternal contribution, indicated by absence of sperm signature siRNAs. Zygote formation is accompanied by widespread redistribution of 24-nt siRNAs relative to gametes, such that ∼70% of the zygote siRNA loci do not overlap any egg cell siRNA loci. Newly detected siRNA loci in zygote are gene-proximal and not associated with centromeric heterochromatin, similar to canonical siRNAs, in sharp contrast to gametic siRNA loci that are gene-distal and heterochromatic. In addition, zygote but not egg siRNA loci are associated with high DNA methylation in the mature embryo. Thus, the zygote begins transitioning before the first embryonic division to an siRNA profile that is associated with future RdDM in embryogenesis. These findings indicate that, in addition to changes in gene expression, the transition to totipotency in the plant zygote is accompanied by resetting of the epigenetic reprogramming that occurred during gamete formation.

Project description:In Arabidopsis, pericentromeric repeats, retroelements, and silenced rRNA genes are assembled into heterochromatin within nuclear structures known as chromocenters. The mechanisms governing higher-order heterochromatin organization are poorly understood but 24-nt small interfering RNAs (siRNAs) are known to play key roles in heterochromatin formation. Nuclear RNA polymerase IV (Pol IV), RNA-DEPENDENT RNA POLYMERASE 2 (RDR2), and DICER-LIKE 3 (DCL3) are required for biogenesis of 24-nt siRNAs that associate with ARGONAUTE 4 (AGO4). Nuclear RNA polymerase V (Pol V) collaborates with DRD1 (DEFICIENT IN RNA-DEPENDENT DNA METHYLATION 1) to generate transcripts at heterochromatic loci that are hypothesized to bind to siRNA-AGO4 complexes and subsequently recruit the de-novo DNA methylation and/or histone modifying machinery. Here, we report that decondensation of the major pericentromeric repeats and depletion of the heterochromatic mark histone H3 lysine 9 dimethylation at chromocenters occurs specifically in pol V and drd1 mutants. Disruption of pericentromeric repeats condensation is coincident with transcriptional reactivation of specific classes of pericentromeric 180-bp repeats. We further demonstrate that Pol V functions independently of Pol IV, RDR2, and DCL3-mediated siRNA production to affect interphase heterochromatin organization, possibly by involving RNAs that recruit structural or chromatin-modifying proteins.

Plant Materials: Seeds were sterilized and sown onto plates containing MSN medium (MS salts supplemented with 1% (w/v) sucrose, pH7 with KOH, 0.6% wt/vol Noble agar). After 2 days at 4°C, the plates were transferred to a growth room with conditions of 22°C/18°C (day/night) and 16h light/8h dark cycle under Philips Cool Daylight TLD 58W/840 fluorescent tubes providing a photosynthetic photon flux density of 130 - 150 umol photons m-2·s-1 as measured using a quantum meter (Model MQ-200 calibrated for electric light source, Apogee). At 18 days after sowing (DAS), the plants were transferred to soil and grown to the reproductive stage in a growth room with controlled light conditions (OSRAM L 36W/865 LumLux Daylight, 130 - 150 umol photons m-2·s-1). To minimize the edge effects, the positioning of both plates and trays on the shelves was rotated every two days. All the plants were grown under the condition described above unless specified. Plant sample preparation and RNA extraction: For the transcriptomes of 15 DAS plants, the aerial tissues of 15 day seedlings were sampled. For the transcriptomes of plants at 28 DAS, the four largest leaves of 28 day plants from the parental lines (C24, Ler), the reciprocal Hybrids and eight F4 Hybrid Mimic lines were harvested. Each sample comprised a pool of five plants. Two biological replicates of each sample were sequenced. Total RNA was isolated using QIAGEN RNeasy MiniKitTM following the product instructions. To eliminate variation in experimental conditions in different positions in the growth room, nine F4 plant lines were divided into two batches to ensure plants were grown on the same shelves in each experiment. Parental lines C24 and Ler and the F1 Hybrid from which the F4 lines derived from were grown under the same conditions in each experiment as controls. The first batch including samples C24 (RepA and RepB), Ler (RepA and RepB), C24 x Ler F1, F4-L1-1, F4-L1-2, F4-L2-1, F4-L2-2 and F4-S-1 were grown under the condition describe above, we also sampled the five smallest C24 seedlings and five smallest Ler seedlings among the population (n = 50); the mRNA sequencing was performed by the Australian Genome Research Facility (AGRF). The second batch including C24 (RepC and RepD), Ler (RepC and RepD), Ler x C24 F1 Hybrid, F4-L3-1, F4-L3-2, F4-L4-1 and F4-L4-2 were grown in the same light intensity as above but under different light tubes (SYLVANIA PREMIUM extra FL36W/865 Super Daylight deluxe light tube). For the transcriptome of the two F6 Hybrid Mimic lines at 15 DAS, C24, Ler, Ler x C24 F1 Hybrids and three siblings from each F6 line (L3-1-1-2 and L4-2-1-2) were grown on MS medium (MS salts supplemented with 1% (w/v) sucrose, pH 5.7 with KOH, add 0.6% wt/vol agar) with controlled light conditions (SYLVANIA PREMIUM extra FL36W/865 Super Daylight deluxe, 130 - 150 umol photons m-2·s-1). The mRNA sequencing service was provided by AGRF on the Illumina platform, 100bp paired ends.

Project description:Hybrid vigor or heterosis refers to the superior performance of F1 hybrid plants over their parents. Heterosis is particularly important in the production systems of major crops. Recent studies have suggested that epigenetic regulation such as DNA methylation is involved in heterosis, but the molecular mechanism of heterosis is still unclear. To address the epigenetic contribution to heterosis in Arabidopsis thaliana, we used mutant genes that have roles in DNA methylation. Hybrids between C24 and Columbia-0 (Col) without RNA polymerase IV (Pol IV) or methyltransferase I (MET1) function did not reduce the level of biomass heterosis (as evaluated by rosette diameter). Hybrids with a mutation in decrease in dna methylation 1 (ddm1) showed a decreased heterosis level. Vegetative heterosis in the ddm1 mutant hybrid was reduced but not eliminated; a complete reduction could result if there was a change in methylation at all loci critical for generating the level of heterosis, whereas if only a proportion of the loci have methylation changes there may only be a partial reduction in heterosis.
