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).

Effects of Ecological Restoration and Climate Change on Herbaceous and Arboreal Phenology.

With global climate change, changes in vegetation phenology have become increasingly evident. Horqin Sandy Land is located near the eastern part of the West Liaohe River. It is the largest sandy land in China and its ecological environment is fragile.

Safety and Efficacy of Tirofiban in Acute Ischemic Stroke Patients Receiving Endovascular Treatment: A Meta-Analysis.

Objectives: Tirofiban is widely used in clinical practice for acute ischemic stroke (AIS). However, whether tirofiban increases the bleeding risk or improves the outcome of AIS patients with endovascular treatment (ET) is unknown. The aim of this meta-analysis is to evaluate the safety and efficacy of tirofiban compared with those without tirofiban in AIS patients receiving ET.
