Project description:Background'Zhongshanshan' is the general designation for the superior interspecific hybrid clones of Taxodium species, which is widely grown for economic and ecological purposes in southern China. Growth is the priority objective in 'Zhongshanshan' tree improvement. A high-density linkage map is vital to efficiently identify key quantitative trait loci (QTLs) that affect growth.ResultsIn total, 403.16 Gb of data, containing 2016,336 paired-end reads, was obtained after preprocessing. The average sequencing depth was 28.49 in T. distichum var. distichum, 25.18 in T. mucronatum, and 11.12 in each progeny. In total, 524,662 high-quality SLAFs were detected, of which 249,619 were polymorphic, and 6166 of the polymorphic markers met the requirements for use in constructing a genetic map. The final map harbored 6156 SLAF markers on 11 linkage groups, and was 1137.86 cM in length, with an average distance of 0.18 cM between adjacent markers. Separate QTL analyses of traits in different years by CIM detected 7 QTLs. While combining multiple-year data, 13 QTLs were detected by ICIM. 5 QTLs were repeatedly detected by the two methods, and among them, 3 significant QTLs (q6-2, q4-2 and q2-1) were detected in at least two traits. Bioinformatic analysis discoveried a gene annotated as a leucine-rich repeat receptor-like kinase gene within q4-2.ConclusionsThis map is the most saturated one constructed in a Taxodiaceae species to date, and would provide useful information for future comparative mapping, genome assembly, and marker-assisted selection.
Project description:Taxodium 'Zhongshanshan 401' is an important economic plant with ornamental and ecological values, and has been widely planted in southeastern China. In this study, the complete chloroplast (cp) genome of T. 'Zhongshanshan 401' was sequenced and illustrated to add the more genetic information. The entire cp genome of T. 'Zhongshanshan 401' was 132,037 bp in length with 35.3% overall GC content. The cp genome contained 120 genes, including 83 protein-coding genes, 33 tRNA genes, and four rRNA genes. Fifteen genes contain two exons and two contains three exons. Phylogenetic analysis based on whole cp genome sequences showed that T. 'Zhongshanshan 401' was more closely related to T. mucronatum.

Project description:To study the roles of NWMN_0641, we used microarray to compare the transcriptome of the NWMN_0641 deletion strain with that of the wild-type Staphylococcus aureus Newman strain. Transcriptome of the NWMN_0641 deletion mutant strain and the wild-type Newman strain
Project description:We sought to understand the change in the global gene expression profile of the ΔYGP1 strain in comparison with the BGL-6_Kl parental strain. The transcriptome analysis revealed the change in expression of genes involved in cell wall structure, biogenesis, and integrity that might contribute to the improvement of the BGL display efficiency phenotype.
