Previously, we mapped the qSPP7 QTL affecting the number of spikelets per panicle (SPP) on rice chromosome 7 using near-isogenic line (NIL WH29001) derived from an interspecific cross between the japonica ‘Hwaseong’ and O. minuta. In the present study, we confirmed this QTL using progeny derived from a cross between IL102, a WH29001 sister line and Hwaseong. Genetic analysis determined that qSPP7 was located between a KASP marker KJ07-049 and RM21605. The O. minuta segment on chromosome 7 introgressed into the Hwaseong background was associated with an increase in SPP. The panicle structure of IL102 revealed that not only the number of SPP increased significantly, but also the number of branches per panicle increased as compared to Hwaseong suggesting that the donor allele of qSPP7 promotes branching in the genetic background of Hwaseong. Linkage analysis indicated that qEhd1 on chromosome 10 is involved in the difference in heading date of IL102 and Hwaseong. Experiments under 3 different day length conditions revealed that IL102 always showed earlier heading and higher SPP as compared to Hwaseong indicating that the effect of qSPP7 in the Hwaseong background was not dependent on photoperiod, and SPP increased in proportion to the number of days to heading.

Low-temperature germinability (LTG) is an important trait for rice direct seeding at temperate and high-altitude region. Previously, five QTLs (quantitative trait loci) for LTG were detected using an interspecific cross population between the Korea japonica cultivar Hwaseong and Oryza rufipogon (IRGSP#105491). O. rufipogon alleles at all loci increased the germination rate at the 13℃ condition. In this study, we tried to confirm and fine-map qLTG1 located on the short arm of chromosome 1. To map the qLTG1, two introgression lines, TR5 and TR20 were crossed to Hwaseong to develop F2:3 populations. QTL analysis confirmed the existence of the qLTG1 and it explained 55.5% and 29.9% of phenotypic variation in two populations, respectively. Substitution mapping using informative recombinant lines indicated that qLTG1 was located in 167-kb region between two SSR markers RM10310 and RM10326. This segment harbored 18 genes with nine of them were annotated with specific gene function. In addition, the O. rufipogon introgression in this region was associated with an increase in spikelets per panicle in the Hwaseong background. The results strongly indicate that the O. rufipogon alleles will be a valuable source of genes in improving japonica rice for low-temperature germinability and yield. To our knowledge, this is the first report to fine-map qLTG1 associated with LTG in rice considering that no QTL for LTG has not been reported near this QTL region from other biparental populations.

Efforts to reduce tobacco use among school children need to be based on understanding of access to cigarettes by these subjects because previous studies indicated that enforcement of laws for controlling tobacco sales seems to not affect teen/school children because they can obtain cigarettes from different sources. This paper aims to describe access to and availability of cigarettes among school students (aged 13-15 years old) according to the data from GYTS Vietnam 2014. In GYTS, a national school-based survey of students of grades 8-10, our findings showed that about 15% school children are current smokers who smoke at home, and that they could easily buy cigarettes from stores (63.2%), or someone else (27.8%), or street vendors (9%). Notably, over 85% of school children answered that they were not refused because of their age. This high percentage was nearly the same in the North (85.7%), the Centre (92.5%), and the South (89.7%) of Viet Nam. These findings show that it is quite easy for school children to obtain cigarettes and this is a crucial challenge for policy makers aiming to reduce tobacco use among youth in general and school-age students in particular.

The aim of this study is to evaluate the effect of yeast extract (YE) and salicylic acid (SA) on the expression of curcuminoid-biosynthesis genes (CzDCS and CURS1-3), and accumulation of curcumin in Curcuma zedoaria cell cultures. The results showed that, in cells treated with YE or SA, the expression levels of curcuminoid genes were 1.14- to 3.64-fold higher than the control (untreated cells), in which the YE exhibited a stronger effect in comparison with SA. Curcumin accumulation also tended to be similar to gene expression, curcumin contents in YE- or SA-treated cells were 1.61- to 2.53-fold higher than the control. The SA treatment at the fifth day of culture stimulated the curcumin accumulation and expression in all four genes compared to that at the beginning. While the YE treatments gave different results, the CzCURS1 and CzCURS3 genes were expressed strongly in cells that were treated at the beginning. However, the CzDCS and CzCURS2 genes showed the opposite expression pattern, they were activated strongly in the treatments at day five of the culture. However, the content of curcumin reached its maximum value on the fifth day of culture in all investigations.

In this work, a model for the microstructure of Sr2-xLaxFeMoO6 nanoparticles samples (0 ≤ x ≤ 0.4) was established based on scanning electron microscopy and magnetic studies. The analysis reveals antiphase crystalline domains in the particles with the size distribution centered around mean values below ~12 nm for all the samples. Such small-size domains are responsible for the superparamagnetic properties observed for temperatures below room temperature, which are dependent on their dipole interactions. According to the fraction of Fe atoms at the antiphase boundaries calculated under the spherical domain assumption, these domains have lower degrees of atomic disorder than those estimated from the saturation magnetization values at 5 K, which are consistent with the high spin polarization values previously reported. The Curie temperature values, and the broadening of the magnetic phase transition can be satisfactorily explained based on the domain size distribution.
