Genetic variation in Arabidopsis thaliana reveals the existence of natural heat resilience factors for meiosis.

Heat interferes with multiple meiotic processes, leading to genome instability and sterility in flowering plants, including many crops. Despite its importance for food security, the mechanisms underlying heat tolerance of meiosis are poorly understood. In this study, we analyzed different meiotic processes in the Arabidopsis (Arabidopsis thaliana) accessions Columbia (Col) and Landsberg erecta (Ler), their F1 hybrids, and the F2 offspring under heat stress (37°C).

Poor accuracy of single serological IgM tests in children with suspected acute infection in Guangzhou, China.

Early and accurate diagnosis of () infection of children with pneumonia is at the core of treatment in clinical practice. Serological immunoglobulin M (IgM) tests for infection of children in south China have been rarely described. To assess the diagnostic performance and clinical application of serodiagnosis of infection in paediatric pneumonia patients.
