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.

Project description:affy_petaldvt_lyon_rose. The objective is to identify genes involved in petal development in rose. We aim at identifying genes whose expression correlates with flower opening and scent emission. In this study, we used a microarray approach to compare the transcriptome of a scented rose flower (PF) versus non-scented rose flower (RF). Samples (petal tissues) were collected at the same time early in the afternoon. Total RNA was extracted using the Plant RNA kit (Macherey Nagel), and then used to hybridize Rosa-Affymetrix microarrays. Keywords: scented vs non-scented flowers 4 arrays - rose. Scented and non-scented flowers, 2 replicates each.

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.

Project description:Investigation of gene expression level changes in snapdragon petals and sepals during flower development The flower developmental stages analyzed in this study are representative of distinct developmental events: (i) preanthesis, (ii) anthesis, (iii) maturation and (iv) presenescence and are further described in the accompanying article. A 24 chip study using total RNA recovered from samples of petal and sepal tissue of Antirrhinum majus cv. Maryland True Pink harvested at four different stages of flower development, namely (i) preanthesis (three days before flower opening=d-3), (ii) anthesis (day of flower opening=d1), (iii) maturation (four days after flower opening=d4) and (iv) presenescence (seven days after flower opening=d7). Three separate samples were extracted per tissue and developmental stages. Each chip measures the expression level of 11,959 ESTs from Antirrhinum majus cv. Maryland True Pink with up to six 60-mer probes per target.

Project description:affy_duplicature_lyon_rose. The objective is to identify the genes involved in petal doubling in rose. In this study we are using two rosa gallica genotypes: wild-type (simple flower rose) and Cardinal de Richelieu (double flower rose), and two rosa hybrida genotypes : Souvenir de la Malmaison, which has about 110 petal, and its bud sport cultivar, Souvenir de St Anne’s. In this study, we used a microarray approach to compare the transcriptome of double flower rose (CDR) versus simple flower rose (G). The objective is to identify genes whose expression is associated with the double flower phenotype. These genes are putative candidates involved in the control of petal organ number per flower. Floral buds were dissected under a microscope and pooled in eppendorf tubes. Tissue samples were harvested at the same time during 3 weeks in April 2007. Total RNA was extracted from the pools of flowers using the Plant RNA kit (Macherey Nagel), and then used to hybridize Rosa-Affymetrix microarrays. Keywords: genotype comparison

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.

Project description:Soybean plants were subjected to water deficit, heat stress, and combination of water deficit and heat stress. Flower parts, sepal, anther, ovary and stigma were collected from 8-10 different plants at R1 stage growing under three above mentioned stress conditions, and under control conditions 10 days after initiation of the stresses. Differential gene expression compared to control was studied using RNAseq method.

Project description:affy_floralangers_rose - affy_floral_rose - - Which genes are induced during floral initiation? - Are the genes involved in floral initiation identical between our 3 genotypes? - Which genes are involved in the control of recurrent blooming in rose? - Which genes are diferentially expressed between buds that will become floral and buds that will remain vegetative?-This project aims to find in rose genes involved in flowering control (floral initiation and recurrent flowering). First, the floral initiation will be observed in 3 genotypes. Then we will check if same genes are regulated within genotypes for this process. Concerning recurrent blooming, we will compare flower bud versus vegetative buds in non-recurrent conditions and finally bud from non-recurrent and recurrent genotypes.
