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

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

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 Unfertilized pistils were obtained growing under low humidity cer6-2 conditional male sterile mutant of Arabidopsis in Ler background. The seven stages considered were: 0-1 dpa, 2-3 dpa, 4-5 dpa, 6-7 dpa, 8-9 dpa 10-11 dpa and 12-14 dpa. Two biological replicas with two technical replicas each were performed for each stage. The biological replicas were grown independently, and all the samples of each one were harvested simultaneously. Amplified RNA from each sample was hibridized together with a global reference over the DNA microarray. The reference was generated from an equimolar mix of amplified RNAs from each of the seven samples of the corresponding biological replica. Amplified RNA from each sample was labelled separately with Cy5 and with Cy3, and each labelling was compared in the DNA microarray with Cy3-labelled and with Cy5-labelled RNA from the reference mix, respectively.

Project description:Flowers have a species-specific fertile period during which pollination and fertilization have to occur to initiate seed and fruit development. Within the flower, the functional life span of the ovule containing the female gametophyte is decisive for fertilization and the initiation of seed development. Here we performed an RNA-sequencing based transcriptome analysis of senescing unfertilized ovules during in a time series. We isolated ovules from Arabidopsis thaliana flowers emasculated at stage 12c at three different time points: 2 days after emasculation (DAE), 3 DAE, and 4 DAE. These time points correspond to intact mature ovules (2DAE), early ovule senescence (3 DAE), and late ovule senescence (4 DAE). We extracted total RNA from the ovules in 3 independent biological replicates, thus generating 9 RNA samples in total, for RNA-sequencing by Illumina HiSeq.

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 Flowers at the developmental stage 12c were emasculated 24 hours before pollination. Pistils were collected at 0, 0.5, 3.5 and 8 Hours After Pollination (HAP) and immediately frozen in liquid nitrogen. Unfertilized ovules were collected by the funiculus from dissected UP and immediately frozen in liquid nitrogen. To minimize biological variation 20 pistils were collected from a minimum of 10 plants and for ovule isolation 50 pistils were used from about 30 plants to isolate approximately 1500 ovules for each replicate experiment.

Project description:Cytokinins are plant hormones with biological functions ranging from coordination of plant growth and development to the regulation of senescence. A series of 2-chloro-N6-(halogenobenzylamino)purine ribosides was prepared and tested for cytokinin activity in selected bioassays. Several compounds showed significant activity, especially in delaying senescence in detached wheat leaves. We used microarrays to gather information about the reprogramming of gene transcription when senescent Arabidopsis leaves were treated with selected C2-substituted aromatic cytokinin ribosides that showed high activity in the senescence bioassay. Arabidopsis senescent leaves were treated with cytokinins and subsequently used for RNA extraction and hybridization on Affymetrix microarrays. 21-days old Arabidopsis leaves were treated with the appropriate cytokinin or left untreated (DMSO only).
