Project description:Stamen development is an important developmental process that directly affects the yield of Prunus sibirica. In this study, the male sterile flower buds and male fertile flower buds of Prunus sibirica were used as materials to performed RNA-Seq analyses to compare transcription differences. The results would provide a theoretical basis for further investigation of the formation mechanism of male sterile flower.
Project description:Pistil development is an important developmental process that directly affects the yield of Prunus sibirica. Through transcriptome sequencing analysis of clones with abortive pistil (No. 595) and normal pistil (No. 28) of Prunus sibirica, a total of 1950 significantly differentially expressed genes were obtained, among which 1000 genes were up-regulated and 950 genes were down-regulated. The results provide a theoretical basis for further investigation of the formation mechanism of pistil abortion.
Project description:We will use high-throughput sequencing technology to study gene expression under NaCl treatment, screen for differential expressed genes, and then analyze the gene regulation features. Nitraria sibirica Pall. seedlings were treated by 0, 100 and 400 mM NaCl with 3 replicates,and the leaves were harvested after treated 3 days. Extracting total RNA of leaves and then sequencing by Illumina HiSeq 2000 sequencing platform. Our study provides a basis for the study of salt-tolerant gene resources in Nitraria sibirica Pall.
Project description:Transcriptome sequencing of non-model organisms is valuable resource of the genetic basis of ecological-meaningful traits. The Royal Irises, Iris section Oncocyclus (Iris: Iridaceae, order Asparagales), are a Middle-East group of species in the course of speciation. The species are characterized with extremely large flowers, a huge range of flower colors and a unique pollination system. The Royal Irises, which are a symbol of conservation in the Middle-east, serve as a model for evolutionary processes of speciation and plant ecology. However, there are not sufficient transcriptomic and genomic data for molecular characterization. Thus, it is necessary to generate massive transcript sequences for functional characterization and molecular marker development for the Royal Irises. The Iris transcriptome sequencing provides valuable resource for studying adaptation-associated traits in this non-model plant. Although intensive eco-evolutionary studies, this is the first reported transcriptome for the Royal Irises. The data available from this study will facilitate gene discovery, functional genomic studies and development of molecular markers in irises, and will provide genetic tools for their conservation.
