UV-B increases active phytochrome B to suppress thermomorphogenesis and enhance UV-B stress tolerance at high temperatures.

Plants respond to slight increases in ambient temperature by altering their architecture, a phenomenon collectively termed thermomorphogenesis. Thermomorphogenesis helps mitigate the damage caused by potentially harmful high-temperature conditions and is modulated by multiple environmental factors. Among these factors, ultraviolet-B (UV-B) light has been shown to strongly suppress this response.

Online citizen petitions related to COVID-19 in South Korean cities: a big data analysis.

What do citizens demand of their governing bodies to cope with the spread of emerging infectious diseases after recognizing the growing danger? What are the similarities and differences in political participation via online citizen petitions regarding COVID-19 across cities with different degrees of pandemic experience? This study aims to answer these questions by examining citizen petitions regarding the COVID-19 pandemic in urban areas of South Korea. The pattern of citizens' requests is a part of integrative socio-ecological and political systems with spatial and temporal dimensions. We compare the pattern of online citizen petitions in four Korean cities, namely Seoul, Busan, Daegu, and Incheon, some of which were epicenters of the COVID-19 outbreak.
