We discuss the gravitational wave(GW) spectra predicted from the electroweak scalegenesis of the Higgs portal type with a large number of dark chiral flavors, which many flavor QCD would underlie and give the dynamical explanation of the negative Higgs portal coupling required to trigger the electroweak symmetry *** employ the linear-sigma model as the low-energy description of dark many flavor QCD and show that the model undergoes ultra-supercooling due to the produced strong first-order thermal phase transition along the(approximately realized) flat direction based on the Gildener-Weinberg mechanism. Passing through evaluation of the bubble nucleation/percolation, we address the reheating and relaxation processes, which are generically non-thermal and nonadiabatic. Parametrizing the reheating epoch in terms of the e-folding number, we propose proper formulae for the redshift effects on the GW frequencies and signal spectra. It then turns out that the ultra-supercooling predicted from the Higgs-portal scalegenesis generically yields none of GW signals with the frequencies as low as nano Hz,unless the released latent heat is transported into another sector other than reheating the universe. Instead, models of this class prefer to give the higher frequency signals and still keeps the future prospected detection sensitivity, like at LISA, BBO, and DECIGO, etc. We also find that with large flavors in the dark sector, the GW signals are made further smaller and the peak frequencies higher. Characteristic phenomenological consequences related to the multiple chiral scalars include the prediction of dark pions with the mass much less than Te V scale, which is also briefly addressed.

A 61-kb biosynthetic gene cluster(BGC), which is accountable for the biosynthesis of hibarimicin(HBM)B from Microbispora rosea subsp. hibaria TP-A0121, was heterologously expressed in Streptomyces coelicolor M1154, which generated a trace of the target products but accumulated a large amount of shunt products. Based on rational analysis of the relevant secondary metabolism, directed engineering of the biosynthetic pathways resulted in the high production of HBM B, as well as new HBM derivates with improved antitumor activity. These results not only establish a biosynthetic system to effectively synthesize HBMs-a class of the largest and most complex Type-II polyketides, with a unique pseudo-dimeric structure-but also set the stage for further engineering and deep investigation of this complex biosynthetic pathway toward potent anticancer drugs.

A Computer Program for Automatic Watering Based on Potential Evapotranspiration by Penman Method and Predicted Leaf Area in Miniature Pot Rose Production

引用

agricultural sciences in China 2010年第3期9卷 370-377页

作者： YU Wen-jin Kitamura Ryo Kato Katsuhiko LI Lian-hua Fukui Hirokazu agricultural College Guangxi University Nanning 530004 P.R.China The United Graduate School of agricultural Science Gifu University Gifu 5011193 Japan Faculty of Applied Biological sciences Gifu University Gifu 5011193 Japan gifu prefectural center for agricultural sciences Gifu 5011152 Japan

In this study, we developed a computer program for automatic prediction of watering time point by considering the environmental factors such as solar radiation, air temperature and relative humidity based on the multiple linear regression equation of leaf area and Penman Method. The experiments were carried out for a year in two watering experimental plots, one of which was controlled by pF value, and the other by the computer program. After comparing the results of the two plots, the following findings were obtained. In the computer program plot, the observed and predicted values of both leaf area and evapotranspiration indicated significant correlation at the 1% level, which suggested that the computer program had high prediction accuracy. In addition, no significant difference was observed between the two experimental plots with respects to the plant height, plant diameter, leaf area, leaf number, fresh weight, and dry weight, which demonstrated that the plants in the computer program plot had normal growth. On the other hand, although the number of flower buds and flowering shoots showed higher values at the end of certain cultivations in the computer program plot than those in pF value plot, we proposed that it was due to the effect of cumulative daily solar radiation in the greenhouse, rather than the watering. Thus, we have reached the conclusion that the computer program for automatic prediction of watering time point developed by this study has high applicability in miniature pot rose production.

This study addresses the hypothesis that stagnation of soybean yield on the farm can be improved by selection of a physiological trait favoring carbon assimilate partitioning to terminally placed pods versus genotypes having axillary pods at close plant spacing.13C was fed to source-sink units comprising a leaf,axillary/terminal pods,and petioles at upper and lower positions of the stem axis in two soybean cultivars,namely Shakujo and Enrei,at different densities of *** cultivars differ significantly in architecture,Shakujo bearing a few hundreds of pods in close succession to one another in a terminally placed raceme,in contrast to Enrei having axillary *** yield per plant was higher in Enrei than in Shakujo at low density,but Shakujo out-yielded Enrei at close *** density decreased yield per plant and altered the pattern of assimilate partitioning significantly within the plants for both *** high density more assimilates moved to the upper parts at the cost of the lower *** terminally placed pods of Shakujo were advantaged to receive assimilates under density *** benefit was accrued to pod filling of Enrei,however,under this condition.

Calcium Signaling in Plant Endosymbiotic Organelles： Mechanism and Role in Physiology

Molecular Plant 2014年第7期7卷 1094-1104页

Recent studies have demonstrated that chloroplasts and mitochondria evoke specific Ca2＋ signals in response to biotic and abiotic stresses in a stress-dependent manner. The identification of Ca2＋ transporters and Ca2＋signaling mol- ecules in chloroplasts and mitochondria implies that they play roles in controlling not only intra-organellar functions, but also extra-organellar processes such as plant immunity and stress responses. It appears that organellar Ca2＋ signaling might be more important to plant cell functions than previously thought. This review briefly summarizes what is known about the molecular basis of Ca2＋ signaling in plant mitochondria and chloroplasts.
