Development of a social contact self-efficacy scale for 'third agers' in Japan.

PLoS One 2021 22;16(6):e0253652. Epub 2021 Jun 22.

Department of Community and Public Health Nursing, Faculty of Medicine/Graduate School of Health Sciences, Hokkaido University, Sapporo, Hokkaido, Japan.

Background: "Third agers" are people over retirement age in relatively good health; third agers make up an increasing percentage of the global population as the world's longevity increases.

Spatial regulation of thermomorphogenesis by HY5 and PIF4 in Arabidopsis.

Nat Commun 2021 06 16;12(1):3656. Epub 2021 Jun 16.

Department of Molecular Biosciences and The Institute for Cellular and Molecular Biology, The University of Texas at Austin, Austin, TX, USA.

Plants respond to high ambient temperature by implementing a suite of morphological changes collectively termed thermomorphogenesis. Here we show that the above and below ground tissue-response to high ambient temperature are mediated by distinct transcription factors. While the central hub transcription factor, PHYTOCHROME INTERCTING FACTOR 4 (PIF4) regulates the above ground tissue response, the below ground root elongation is primarily regulated by ELONGATED HYPOCOTYL 5 (HY5).

PeerJ 2021 1;9:e11553. Epub 2021 Jun 1.

Department of Geography, Minjiang University, Fuzhou, China.

Elevation is important for determining the nutrient biogeochemical cycle in forest ecosystems. Changes in the ecological stoichiometry of nutrients along an elevation gradient can be used to predict how an element cycle responds in the midst of global climate change. We investigated changes in concentrations of and relationships between nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg) in the leaves and roots of the dominant tree species, along an elevation gradient (from 500 to 1,000 m above mean sea level) in a subtropical natural forest in China.
