Project description:Metagenome sequencing All specimens were collected and immediately stored in a -80 freezer. All BALF samples were subjected to MS. DNA was extracted from BALF using the TIANamp Micro DNA kit (DP316, Tiangen Biotech). DNA libraries were constructed with the end-repair method and then sequenced on the BGI Sequencer platform (BGI Genomics, Shenzhen, China). Bioinformatic pipeline analysis Low-quality and short (<35 bp) reads were removed from raw data using fastp [10]. Remaining reads were mapped to the human reference genome (hg19) using the Burrows-Wheeler method to remove sequences of human origin. Filtered reads were classified with RefSeq, downloaded from NCBI (ftp://ftp.ncbi.nlm.nih.gov/genomes/).
Project description:Rice (Oryza sativa) is one of the world's major rations. The widely planted hybrid rice in Jiangxi Province is seriously affected by Magnaporthe oryzae, which seriously restricts the rice yield in Jiangxi Province. In recent years, studies have found that alternative polyadenylation (APA) is an important post-transcriptional regulation in eukaryotes. The genetic law and function of APA in the occurrence of hybrid rice blast in Jiangxi are not clear. In this study, Wufengyou T025 (WFY) and its parents (male parent Changhui T025(CH), and female parent Wufeng B(WFB)) were used as the research objects. Transcriptome and metabolome sequencing, combined with a variety of bioinformatics analysis methods and modern molecular biology experimental techniques, revealed the APA expression profile during the occurrence of Jiangxi hybrid rice blast. To explore the regulatory mechanism of APA core factors during the occurrence of rice blast. This study not only provides a new understanding of the occurrence of Jiangxi hybrid rice blast, but also provides more abundant resources for molecular breeding.
