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 performed transcript profiling of male sterile and fertile buds from a multiple-allele inherited male sterile AB line using the Illumina high-throughput sequencing platform and analyzed differential gene expression at the transcriptional level.
Project description:Investigation of comprehensive gene expression level changes in male strobili of sterile mutant, compared to the fertile plant. We designed a new custum array derived from ESTs of Cryptomeria japonica for this study. Male strobili of C. japonica were collected from Toyama 1 half-sib F2 pedigree. Toyama 1 male-sterile mutant was first reported in Saito, M. , H. Taira, and Y. Furuta (Journal of Forest Research 3(3):167-173).
Project description:Cotton (Gossypium spp.) is one of the most important economic crops and exhibits yield-improving heterosis in specific hybrid combinations. The genic male-sterility system is the main strategy used for producing heterosis in cotton. To better understand the mechanisms of male sterility in cotton, we carried out label-free quantitative proteomics analysis in the anthers of two near-isogenic lines, the male-sterile line 1355A and the male-fertile line 1355B, the two isogenic lines. These experiments, along with bioinformatics analyses, identified 124 proteins from the anthers at uninucleate pollen stage (stage 8) that were significantly differentially expressed between these two lines.

We designed a new custum array derived from ESTs of Cryptomeria japonica for this study. Male strobili of C. japonica were collected from Toyama 1 half-sib F2 pedigree. Toyama 1 male-sterile mutant was first reported in Saito, M. , H. Taira, and Y. Furuta (Journal of Forest Research 3(3):167-173). Microarray studies using both individual samples and pooled samples were performed. Total RNA was extracted from male strobili at four developmental stages derived from each seven fertile and male-sterile trees as individual samples. Pooled RNA samples were prepared from four to eight different fertile and sterile plants at three developmental stages.
