Project description:We conducted micro-array analysis to quantify the global transcriptome variations in floral organs of a male and female tree allowing for identification of sex-linked transcripts. We used RNA samples from male floral buds in August and female floral buds in Spetemeber. Bud scale were removed. While the sampling time differed, the developmental stage of the floral organs was similar between the male and female.

Project description:We conducted micro-array analysis to quantify the global transcriptome variations in floral organs of a male and female tree allowing for identification of sex-linked transcripts. We used RNA samples from male floral buds in August and female floral buds in September. Bud scale were removed. While the sampling time differed, the developmental stage of the floral organs was similar between the male and female. Five independent samples of floral bud tissues with bud scales removes were collected from the upper crown of a sexually mature male tree and female tree. RNA was extracted from tissues and hybridized on Affymetrix Genechip Poplar Genome Array.

Project description:We conducted micro-array analysis to quantify the global transcriptome variations in floral buds through the course of the year allowing for identification of changing developmental signals. We used RNA samples from floral buds, with bud scale removed, in the upper crown of a sexually mature Populus deltoides tree 2 hours after sunrise. Three independent samples of floral bud tissues with bud scales removes were collected from the upper crown of a single sexually mature male tree. RNA was extracted from tissues and hybridized on Affymetrix Genechip Poplar Genome Array.

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. Keywords: time course

Project description:Background: Vicia sativa (the common vetch) possesses a predominant zygomorphic flower and belongs to the subfamily Papilionoideae, which is related to Arabidopsis thaliana in the eurosid II clade of the core eudicots. Each vetch flower consists of 21 concentrically arranged organs: the outermost five sepals, then five petals and ten stamens, and a single carpel in the center. Methodology/Principal Findings: We explored the floral transcriptome to examine a genome-scale genetic model of the zygomorphic flower of vetch. mRNA was obtained from an equal mixture of six floral organs, leaves and roots. De novo assembly of the vetch transcriptome using Illumina paired-end technology produced 71,553 unigenes with an average length of 511 bp. We then compared the expression changes in the 71,553 unigenes in the eight independent organs through RNA-Seq Quantification analysis. We predominantly analyzed gene expression patterns specific to each floral organ and combinations of floral organs that corresponded to the traditional ABC model domains. Comparative analyses were performed in the floral transcriptomes of vetch and Arabidopsis, and genomes of vetch and Medicago truncatula. Conclusions/Significance: Our comparative analysis of vetch and Arabidopsis showed that the vetch flowers conform to a strict ABC model. We analyzed the evolution and expression of the TCP gene family in vetch at a whole-genome level, and several unigenes specific to three different vetch petals, which might offer some clues toward elucidating the molecular mechanisms underlying floral zygomorphy. Our results provide the first insights into the genome-scale molecular regulatory network that controls the evolution and development of the zygomorphic flower in Papilionoideae. Examination of the transcriptomic changes in the six floral organs, leaves and roots in common vetch.

Project description:For identifying genes for sex determination in papaya, digital gene expression analysis by Ht-SuperSAGE (Matsumura et al., 2010) was carried out in flowers from male, female and hermaphrodite plants of papaya. Total more than 9,273,744 26bp-tags were obtained by sequence analysis using SOLiD3 and mapped on papaya primitive sex chromosome sequences. 6 samples examined: male young flowerbud, male mature flower bud, female young flower bud, female mature flower bud, hermaphrodite young flower bud, hermaphrodite mature flower bud
