Transcription profiling of Gerbera hybrida flower organs vs a reference pool

ABSTRACT: Different gerbera hybrida flower organs including pappus bristles, stamen, early and late petal development and flower scape, were compared to a pooled reference sample to determine which genes are abundant for analyzed flower organs. Samples were pooled and included two biological replicants with three technical replicants that were independently labelled were included. Each biological replicant included one dye swap technical repeat. Gerbera 9K cDNA microarrays were used for hybridizations.

Development of composite inflorescences in the plant family Asteraceae has features that cannot be studied in the traditional model plants for flower development. In Gerbera hybrida, inflorescences are composed of morphologically different types of flowers tightly packed into a flower head (capitulum). Individual floral organs such as pappus bristles (sepals) are developmentally specialized, stamens are aborted in marginal flowers, petals and anthers are fused structures, and ovaries are located ...[more]

Transcription profiling of callus, petals and stamens from wild type and gmyb10 over-expressing gerbera plants in order to identify target genes for gmyb10 in the anthocyanin pathway

Project description:In the microarray experiment a comparison of different flower organs of transformed transgenic gerbera line to wild type gerbera was done. In the transgenic gerbera line the gene gmyb10 that regulates anthocyanin pathway is over-expressed. In this line anthocyanin pigmentation is altered compared to the wild type. In this experiment RNA from dark red callus, two stage of petal development and stamens of the transgenic lines were compared to RNA of wild type in order to identify target genes for gmyb10.

Transcription profiling of Gerbera hybrida flower organs vs leaf

Project description:Gerbera inflorescence sample was compared with a gerbera leaf sample in order to identify flower specific genes. Samples were pooled from different developmental stages and 4 replicants were independently labelled. All labellings/hybridizations included two dye swap replicants. Gerbera 9K cDNA microarrays were used for the hybridizations.

Transcription profiling of Gerbera inflorescence sample was compared with a gerbera leaf sample

Project description:Gerbera inflorescence sample was compared with a gerbera leaf sample in order to identify flower specific genes. Samples were pooled from different developmental stages and alltogether 8 replicates (including 2 biological replicates with 4 technical replicates each) were independently labelled. Both biological replicates included two dye swap replicates. Gerbera 9K cDNA microarrays were used for the hybridizations.

Transcription profiling of Gerbera petals of developmental stages 2, 4, 6, 7, 8, and 9 vs a reference sample to identify transcriptional changes in petal development

Project description:Gerbera petals of inflorescence developmental stages 2, 4, 6, 7, 8, and 9 were compared against a reference sample that included same amount of mRNA from stages 1-11. Alltogether six comparisons were done each including two biological replicates with 3 technical replicates resulting alltogether 36 hybridizations. At least one of each biological replicate was dyeswap hybridization. This experiment was done in order to profile transcriptional changes that occur in petals from stage where they still divide until senescence of the cells. Developmental stages have been characterized by Helariutta et al. (1995).

EST sequencing and microarray analysis of the floral transcriptome of Eustoma grandiflorum

Project description:Genome-wide DNA sequence resources are expected to enhance our understanding of the molecular basis of plant development and lead to improvements in desirable traits in horticultural crops. In this study, we sequenced 643,366 ESTs from Eustoma grandiflorum flowers using a normalised cDNA library constructed for several different flower development stages, times of day, and pollinated stamens. The sequences were assembled into 63,401 contigs and 242,212 singletons. BlastX searches for all of the contigs in the GenBank database matched 65% of the contigs to registered sequences, while 35% presented no hits. GO mapping assigned 48% of the 63,401 contigs to GO terms. Microarray analysis showed that subsets of genes were up- or downregulated as the flower developed. The downregulated genes were enriched for GO terms related to 1) oligopeptide transport, 2) response to jasmonic acid stimulus, and 3) cell wall modification, whereas the upregulated genes were enriched for GO terms involved in 1) secondary metabolism, such as the flavonoid biosynthetic process and the terpenoid biosynthetic process, and 2) epidermal cell modification. Two-condition experiment, loop-design among 4 developmental stages. Biological replicates: 4.

Expression profiling of Arabidopsis leaf, flower and fruit development

Project description:With the quantitative profiling of consecutive tissue growth stages, we provide a global overview of expression changes of individual genes that play a role in dynamic cellular processes and developmental changes. We used tandem mass tag-based mass spectrometry and RNA sequencing to generate proteomic, phosphoproteomic and transcriptomic expression profiles for rosette leaf, flower and fruit tissue samples of the model plant Arabidopsis thaliana. In doing so, we have generated a multi-omics dataset of progressive changes during the development of three important plant organ types that can be used to study the underlying molecular mechanisms from different angles.
