Expression data from Arabidopsis pollen and semi in vivo- and in vitro-grown pollen tubes.

Project description:Pollen tubes extend through pistil tissues and are guided to ovules where they release sperm for fertilization. Although pollen tubes can germinate and elongate in a synthetic medium, their trajectory is random and their growth rates are slower compared to growth in pistil tissues. Furthermore, interaction with the pistil renders pollen tubes competent to respond to guidance cues secreted by specialized cells within the ovule. The molecular basis for this potentiation of the pollen tube by the pistil remains uncharacterized. We used a surgical procedure to obtain large quantities of uncontaminated pollen tubes that grew through the pistil and defined their transcriptome by microarray analysis. We also characterized the transcriptome of in vitro-grown pollen tubes (for 0.5hours or 4hours) and dessicated mature pollen in Arabidopsis.

Arabidopsis unfertilized pistil development and senescence

Project description:Transcription profiling of post-anthesis unfertilized pistil development and senescence in Arabidopsis, in a serie including samples from seven different stages according to pistil age in days post-anthesis (dpa). The time course started at anthesis and ended at 12-14 dpa, several days later of the loss of fruit set capacity. Keywords: Developmental time course

A plant-specific ISWI subunit is involved in fertility by inhibiting the pistil overgrowth

Project description:we identified the forkhead-associated domain 2 (FHA2) as a plant-specific subunit of an ISWI chromatin-remodeling complex in Arabidopsis. By in vivo and in vitro analyses, we demonstrated that FHA2 directly binds to RLT1 and RLT2, two redundant subunits of the ISWI complex in Arabidopsis. A reduced-fertility phenotype was observed in both the fha2 and rlt1/2 mutant plants and the phenotype was ascribed to overgrowth of the pistil during the floral development. However, the early-flowering phenotype of the rlt1/2 mutant was not shared by the fha2 mutant. Consistently, our RNA-seq analysis indicated that the fha2 mutant affects a subset of rlt1/2-regulated genes but not genes involved in the regulation of flowering time. This study demonstrates that FHA2 functions as a previously uncharacterized subunit of the Arabidopsis ISWI complex to exclusively regulate the pistil growth during the floral development.

Targets of FRUITFULL in the pistil/silique [ChIP-Seq]

Transcriptomic analysis reveals genes releated to pistil abortion in Prunus sibirica

Project description:Pistil development is an important developmental process that directly affects the yield of Prunus sibirica. Through transcriptome sequencing analysis of clones with abortive pistil (No. 595) and normal pistil (No. 28) of Prunus sibirica, a total of 1950 significantly differentially expressed genes were obtained, among which 1000 genes were up-regulated and 950 genes were down-regulated. The results provide a theoretical basis for further investigation of the formation mechanism of pistil abortion.

Whole genome analysis of pollen-pistil interactions in Arabidopsis thaliana: time course

Project description:Plant reproduction depends on the concerted activation of many genes to assure the correct communication between pollen and pistil. Here we queried the whole transcriptome of Arabidopsis thaliana in order to identify genes with specific reproductive functions. We used the ATH1 whole genome array to profile wild-type unpollinated pistils and unfertilized ovules in comparison with the expression profile of pistils 0.5, 3.5 and 8.0 hours after pollination KEYWORDS: time course
