is a globally important vegetable and oil crop. The research is meaningful for the yield and plant architecture of . In this study, one natural mutant line with determinate and capitulum-like inflorescence was chosen for further study. Genetic analysis indicated that the segregation patterns of inflorescences in the F populations supported a digenic inheritance model, which was further approved via the BSA-Seq technique. The BSA-Seq method detected two QTL regions on C02 (14.27-18.41 Mb) and C06 (32.98-33.68 Mb) for the genetic control of determinate inflorescences in MT plants. In addition, the expression profile in MT compared with WT was analyzed, and a total of 133 candidate genes for regulating the flower development (75 genes, 56.4%), shoot meristem development (29 genes, 21.8%), and inflorescence meristem development (13 genes, 9.8%) were identified. Then one joint analysis combing BSA-Seq and RNA-Seq identified two candidate genes of and for regulating the MT phenotype. Furthermore, the potential utilization of the MT plants was also discussed.

Background: Butyrate may inhibit SARS-CoV-2 replication and affect the development of COVID-19. However, there have been no systematic comprehensive analyses of the role of butyrate metabolism-related genes (BMRGs) in COVID-19.
Methods: We performed differential expression analysis of BMRGs in the brain, liver and pancreas of COVID-19 patients and controls in GSE157852 and GSE151803.

Background: The swift rise in the prevalence of Alzheimer's disease (AD) alongside its significant societal and economic impact has created a pressing demand for effective interventions and treatments. However, there are no available treatments that can modify the progression of the disease.
Methods: Eight AD brain tissues datasets and three blood datasets were obtained.
Inducible regulating homologous recombination enables precise genome editing in Pichia pastoris without perturbing cellular fitness.

The methylotrophic yeast Pichia pastoris (also known as Komagataella pastoris) is an ideal host for producing proteins and natural products. Enhancing homologous recombination (HR) is helpful for improving the precision of genome editing, but results in stress to cellular fitness and is harmful for industrial applications. To overcome these challenges, we developed a tetracycline repressor protein (TetR)/tetO2 inducible system to dynamically regulate the HR-related gene RAD52 in P.

Background: Maternal smoking and foetal exposure to nicotine and other harmful chemicals in utero remains a serious public health issue with little knowledge about the underlying genetics and consequences of maternal smoking in ageing individuals. Here, we investigated the epidemiology and genomic architecture of maternal smoking in a middle-aged population and compare the results to effects observed in the developing foetus.
Methods: In the current project, we included 351,562 participants from the UK Biobank (UKB) and estimated exposure to maternal smoking status during pregnancy through self-reporting from the UKB participants about the mother's smoking status around their birth.

Breast cancer has emerged as the leading cause of global cancer incidence, surpassing lung cancer. Accumulating evidence suggests that probiotics exhibit inhibitory effect on breast cancer progression, highlighting the need to identify gut flora-derived probiotics with potential anti-breast cancer properties. Here, we investigated the effect of the cell-free supernatant of C.
