Project description:Here we examine the expression of genes in unstimulated or following intraperitoneal injection with MegaFasL in MSM/Ms and C57BL/6 mouse livers and thymi This dataset is from two groups of 2 mice (1 MSM/Ms [MSM] and 1 C57BL/6 [B6] mouse) - either untreated (#1-#4) or injected intraperitoneally with 1.5ug of MegaFasL (#5-#8). Each group has four (4) samples - one liver (L) and one thymus (T) sample from each mouse. The liver and thymi were harvested from the same mouse. Unstimulated samples: 1_S1 = B6 T, 2_S=MSM T, 3_S3=B6 L, 4_S4=MSM L; MegaFasL-injected samples: 5_S1=B6 T, 6_S2=MSM T, 7_S3=B6 L, 8_S4=MSM L.

Project description:To investigate mouse intersubspecific divergence of transcriptional regulation between C57BL/6J (B6) and Japanese wild-derived MSM/Ms strains, we performed transcriptome analysis by microarray on liver from B6 and MSM, and B6-ChrNMSM chromosome substitution strain panel, which carries MSM-derived chromosome or chromosomal segment on the B6 host.
Project description:To analyze the difference in gene expression between alleles of F1 hybrids of mouse C57BL6/J (B6) and MSM/Ms (MSM) strains, we sequenced these F1 hybrids of reciprocal crosses. While most genes did show allelic bias, a small number of genes showed either B6- or MSM-biaed expression in both crosses. These allelic differences were associated with the allelic differences in histone acetylation in promoter regions determined by another experiments.
Project description:The hybrid seed production was performed using the male sterility line, which is an important way of heterosis utilization in Chinese cabbage. A stably inherited male sterile mutant msm was obtained from a Chinese cabbage DH line ‘FT’ using the isolated microspore culture combined with 60Co γ-rays mutagenesis. Compared to the wild type ‘FT’, the msm exhibited completely degenerated stamens and no pollen phenotype, and other characters had no significant difference except for stamen. The genetic analysis indicated that the msm mutant phenotype was controlled by a single recessive nuclear gene. Cytological observation showed that the stamen abortion of msm began at the tetrad period, and tapetum cells were abnormally expanded and highly vacuolated, leading to microspore abortion. Comparative transcriptome analysis on the flower buds of ‘FT’ and msm using RNA-Seq technology revealed a total of 1,653 differentially expressed genes (DEGs). Among which, a large number of genes associated with male sterility were found, including 64 pollen development and pollen tube growth-related genes, 94 pollen wall development-related genes, 11 phytohormone-related genes and 16 transcription factor-related genes, and the overwhelming majority of these genes were down-regulated in the msm vs. ‘FT’ comparison. Furthermore, KEGG pathway analysis indicated that a variety of carbohydrate metabolic and lipid metabolic pathways were significantly enriched, which may be related to pollen abortion. The expression patterns of 24 male sterility-related genes were analyzed using qRT-PCR. In addition, a total of 24,476 single nucleotide polymorphisms and 413,073 insertion-deletion events were specifically detected in msm. These results facilitate to elucidate the regulatory mechanisms of male sterility in Chinese cabbage.
