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).

Transcriptome analysis in petals and leaves of chrysanthemums with different chlorophyll levels

Project description:To identify the regulatory steps that control chlorophyll accumulation, we compared gene expression in petals and leaves of chrysanthemum cultivars with different chlorophyll levels. Microarray analyses showed that the expression levels of chlorophyll biosynthesis genes encoding glutamyl-tRNA reductase, Mg-protoporphyrin IX chelatase, Mg-protoporphyrin IX monomethylester cyclase, and protochlorophyllorophyllide oxidoreductase were well associated with chlorophyll content: their expression levels were lower in white petals than in green petals, and were highest in leaves. Among chlorophyll catabolic genes, expression of STAY-GREEN, encoding Mg-dechelatase, which is a key enzyme controlling chlorophyll degradation, was considerably higher in white and green petals than in leaves. We searched for transcription factor genes whose expression was well related to chlorophyll level in petals and leaves and found several such genes.

Asymmetric bending of lateral petals, a novel trait originated within Delphinium (Ranunculaceae), reinforces their mirrored helical rotation during flower opening

Project description:During the process of flower opening, most petals move downward in the direction of pedicel (i.e., epinastic movement). In most Delphinium flowers, however, their two lateral petals display a very peculiar movement, the mirrored helical rotation. Such a distinctive petal movement requires the twist of the stalk. However, in some lineages, their lateral petals also exhibit asymmetric bending that increases the degree of mirrored helical rotation, facilitating the formation of a 3D final shape. Notably, the petal asymmetric bending is a novel trait that has not been noticed yet so that its morphological nature, developmental process and molecular mechanisms remain largely unknown. Here, by using D. anthriscifolium as a model, we determined that the petal asymmetric bending was caused by localized expansion of cell width, accompanied with specialized arrangement of surface ornamentation, on the adaxial epidermis. Digital gene analyses, gene expression and functional studies revealed that a class I homeodomain-leucine zipper family transcription factor gene, DeanLATE MERISTEM IDENTITY1 (DeanLMI1), contributes to the petal asymmetric bending; knockdown of it led to the formation of explanate 2D petals. Specifically, DeanLMI1 promotes cell expansion in width and influences the arrangement of surface ornamentation, through regulating the auxin distribution, on the localized adaxial epidermis. These results not only provide a comprehensive portrait of petal asymmetric bending for the first time, but also shed some new insight into the mechanisms of flower opening and helical movement in plants.

Proteome and Ubiquitome Changes during Rose Petal Senescence

Project description:Petal senescence involves numerous programmed changes in biological and biochemical processes. Ubiquitination plays a critical role in protein degradation, a hallmark of organ senescence. Therefore, we investigated changes in the proteome and ubiquitome of senescing rose (Rosa hybrida) petals to better understand their involvement in petal senescence. Of 3859 proteins quantified in senescing petals, 1198 were up-regulated and 726 were down-regulated during senescence. We identified 2208 ubiquitinated sites including 384 with increased ubiquitination in 298 proteins and 1035 with decreased ubiquitination in 674 proteins. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses revealed that proteins related to peptidases in proteolysis and autophagy pathways were enriched in the proteome, suggesting that protein degradation and autophagy play important roles in petal senescence. In addition, many transporter proteins accumulated in senescing petals, and several transport processes were enriched in the ubiquitome, indicating that transport of substances is associated with petal senescence and regulated by ubiquitination. Moreover, several components of the brassinosteroid (BR) biosynthesis and signaling pathways were significantly altered at the protein and ubiquitination levels, implying that BR plays important roles in petal senescence. Our data provide a comprehensive view of rose petal senescence at the posttranslational level.

Comparative gene expression in floral whorls of the basal eu-dicot Aquilegia formosa

Project description:Investigation of genome-wide gene expression in sepals, petals, stamens, staminodia and carpels in pre-anthesis Aquilegia flowers. One goal was to identify transcriptional signatures associated with petaloidy by comparing gene expression in petals and petaloid sepals. Other goals were to study the evolutionary origin and ecological function of staminodia by comparing a) expression patterns in stamens, staminodia and carpels, b) identifying transcriptional regulators expressed in staminodia and c) using gene set enrichment analysis to identify biological processes operating in staminodia.

Expression profiles of water deficit stress (WDS) regulated genes in rose petals

Project description:Water deficit stress (WDS) is a crucial factor that causes the inhibition of petal expansion and abnormal flower opening in rose. The regulatory mechanisms of petal expansion by WDS at transcriptional level were investigated by analysis expression profiles under WDS. Analysis used total RNA samples of petals taken from flowers treated by WDS comparison to those from control flowers. Transcriptome dynamics during treatment time responsive to WDS.
