TL;DR: In this paper, the authors report tree census data collected in a network of 34 forest sites in Japan and provide species abundance, survivorship and stem girth growth of 52,534 individuals of 334 tree and liana species.
Abstract: This data paper reports tree census data collected in a network of 34 forest sites in Japan. This is the largest forest data set freely available in Japan to date. The network is a part of the Monitoring Sites 1000 Project launched by the Ministry of the Environment, Japan. It covers subarctic to subtropical climate zones and the four major forest types in Japan. Forty-two permanent plots, usually 1 ha in size, were established in old-growth or secondary natural forests. Censuses of woody species ≥15 cm girth at breast height were conducted every year or once during 2004 to 2009. The data provide species abundance, survivorship and stem girth growth of 52,534 individuals of 334 tree and liana species. The censuses adopted common census protocol, which provide good opportunities for meta-analyses and comparative studies among forests. The data have been used for ecological studies as well as for the biodiversity reports published by the Ministry of the Environment.

TL;DR: This is the first successful attempt to evaluate the coronal magnetic field models by using the Sun's shadow observed in the TeV cosmic-ray flux, and it is found that the intensity deficit in the simulated Sun’s shadow is very sensitive to the corona magnetic field structure.
Abstract: We report on a clear solar-cycle variation of the Sun's shadow in the 10 TeV cosmic-ray flux observed by the Tibet air shower array during a full solar cycle from 1996 to 2009. In order to clarify the physical implications of the observed solar cycle variation, we develop numerical simulations of the Sun's shadow, using the potential field source surface model and the current sheet source surface (CSSS) model for the coronal magnetic field. We find that the intensity deficit in the simulated Sun's shadow is very sensitive to the coronal magnetic field structure, and the observed variation of the Sun's shadow is better reproduced by the CSSS model. This is the first successful attempt to evaluate the coronal magnetic field models by using the Sun's shadow observed in the TeV cosmic-ray flux.

TL;DR: The morphological features and textures in condensed domains formed during first-order phase transition in adsorbed monolayers of 2-hydroxyethyl laurate have been studied at different temperatures as discussed by the authors.
Abstract: The morphological features and textures in condensed domains formed during first-order phase transition in adsorbed monolayers of 2-hydroxyethyl laurate have been studied at different temperatures. Domains in these monolayers are not observed at ≥26 °C, indicating that the critical temperature for the phase transition is near this value. Under equilibrium conditions, the shapes of the domains show a transition from circular to fingering pattern near 15 °C. The domains have more branching in their structures with a further increase in the temperature. Increased formation rate by a temperature jump causes fractal domains at ≥15 °C but does not change the domain shapes at lower temperatures. The fractal structures formed by a high growth rate undergo relaxation to their equilibrium shapes within 25 min. A continuous variation in the textures of the domains with temperature is observed. Similar to the shape transition, above 13 °C the domains show a transition from stripe texture to one of uniform molecular o...

TL;DR: A clone encoding a putative angiotensin-converting enzyme-related gene from the wing disc cDNA library of the silkworm, Bombyx mori, suggests that the transcription of the BmAcer gene is directly 20E-inducible.

TL;DR: The hst1 gene is precisely introgressed, transferring salinity tolerance from “Kaijin” into high-yielding “Yukinko-mai” (WT) rice through single nucleotide polymorphism (SNP) marker-assisted selection to develop a new salt-tolerant rice germplasm using speed-breeding.
Abstract: Salinity critically limits rice metabolism, growth, and productivity worldwide. Improvement of the salt resistance of locally grown high-yielding cultivars is a slow process. The objective of this study was to develop a new salt-tolerant rice germplasm using speed-breeding. Here, we precisely introgressed the hst1 gene, transferring salinity tolerance from “Kaijin” into high-yielding “Yukinko-mai” (WT) rice through single nucleotide polymorphism (SNP) marker-assisted selection. Using a biotron speed-breeding technique, we developed a BC3F3 population, named “YNU31-2-4”, in six generations and 17 months. High-resolution genotyping by whole-genome sequencing revealed that the BC3F2 genome had 93.5% similarity to the WT and fixed only 2.7% of donor parent alleles. Functional annotation of BC3F2 variants along with field assessment data indicated that “YNU31-2-4” plants carrying the hst1 gene had similar agronomic traits to the WT under normal growth condition. “YNU31-2-4” seedlings subjected to salt stress (125 mM NaCl) had a significantly higher survival rate and increased shoot and root biomasses than the WT. At the tissue level, quantitative and electron probe microanalyzer studies indicated that “YNU31-2-4” seedlings avoided Na+ accumulation in shoots under salt stress. The “YNU31-2-4” plants showed an improved phenotype with significantly higher net CO2 assimilation and lower yield decline than WT under salt stress at the reproductive stage. “YNU31-2-4” is a potential candidate for a new rice cultivar that is highly tolerant to salt stress at the seedling and reproductive stages, and which might maintain yields under a changing global climate.
