Oak displays common local but specific distant gene regulation responses to different mycorrhizal fungi

tailieu.vn

sequencing approach, we compared the impact of three ectomycorrhizal (EMF) and one orchid mycorrhizal fungi (OMF) on gene regulation in colonized roots (local), non-colonized roots (short distance) and leaves (long distance) of the Quercus robur clone DF159 with reference to the recently published oak genome.

Cơ chế đóng mở gene diễn ra như thế nào trong tế bào? Mở là những hoạt động tức thời của tế bào chỉ do một phần nhỏ các gen. Đóng là giai đoạn các gen biểu hiện. Quá trình đóng mở gen được biết đến như diều hòa gen (gene regulation). Điều hòa gen là một phần quan trọng của sự phát triển bình thường. Gen đóng mở theo nhiều phương thức khác nhau trong suốt quá trình phát triển, chẳng hạn, cách tạo nên tế bào não nhìn bao quát và hoạt động khác biệt so với một tế bào sống hay một tế bào cơ.

Dynamic network inference and association computation discover gene modules regulating virulence, mycotoxin and sexual reproduction in Fusarium graminearum

tailieu.vn

Thirdly, in 70% of the modules whose top regulators are associated with mycotoxin (DON or ZEA) production, regulation of module genes by the top regu- lator was found under 50% or more of the conditions that lead to mycotoxin induction (Additional file 9). In summary, 24 of the 32 predicted top regulators (75%) for 34 of the 48 predicted modules (70%) showed high concordance between the regulator phenotype and condition-specific gene regulation..

Furthermore, a global functional annotation of the DEGs using GO terms indi- cated an induction in the expression of genes involved in biological regulation and catabolic processes, those. Figure S3), suggesting that PvRbohB plays a role in the signaling and gene regulation processes of P. In response to rhizo- bial inoculation, 1402 genes were upregulated in the control roots. however, only 293 of these genes were also induced in the inoculated PvRbohB-RNAi roots (Fig.

DNA methylation and its effects on gene expression during primary to secondary growth in poplar stems

tailieu.vn

Since transcription factors (TFs) lie at the center of gene regulation, we identified TFs with pronounced alterna- tions in methylation levels. 30.39%, and ~ 5.72% methylation levels in CG, CHG, and CHH contexts (Additional file 1), respectively. Although methylation levels in poplar stems fell into the ranges described for other angiosperms (CG.
