    Abstract Single nucleotide polymorphisms (SNPs) have been proved to be powerful markers in genetic analysis due to their high abundance and polymorphism in plant genomes. The recently developed high-resolution melting (HRM) analysis method provides a novel, quick, and close-tube PCR approach to analyze SNP variations. In present study, 101 HRM-based SNP markers from 20 soybean chromosomes were developed for genotyping vegetable soybean cultivar ‘Zhexian No.9 ’with ‘Williams 82 ’as reference. 33.7% of these markers were polymorphic between ‘Zhexian No.9 ’and ‘Williams 82'. Polymorphic markers were found on 85% (17 of 20) of the soybean chromosomes when comparing ‘Zhexian No.9 ’and ‘Williams 82'. Finally, an array of 101 in-sequence nucleotide letters was generated as the first precise SNP fingerprint of ‘Zhexian No.9'. The described marker-developing methodology could be used in other crops with known genomic information.

    Abstract The effects of photoperiod on nymphal growth and adult reproduction were investigated in a small cockroach, Margattea satsumana, living on the subtropical, Hachijo island (33°N), Japan. Nymphal development is slow under constant photoperiods at 25°C. The shortest mean duration of nymphal development (176 days) is observed at LD 14 : 10 h, followed by LD 12 : 12 h (221 days) and LD 16 : 8 h (309 days). Nymphal development is further prolonged when the nymphs are transferred from LD 12 : 12 to LD 16 : 8 h at 90 days after hatching. However, rapid and synchronized development is observed when nymphs were transferred in the opposite direction. A decreased change in photoperiod from LD 14 : 10 to LD 12 : 12 h also reduces the duration of nymphal development, and this cannot be explained by the results obtained at constant photoperiods. Similarly, nymphs reared at LD 16 : 8 h during the first 60 days mature more rapidly when transferred to LD 12 : 12 h than when transferred to LD 14 : 10 h. The developmental suppression induced by long days may represent a form of summer diapause that is terminated rapidly by short days. Based on these observations and field-census data, it is suggested that this cockroach has a univoltine life cycle overwintering as nondiapause adults, and that this life cycle is stabilized by the response to changing photoperiod.

  4. Article: Photoperiod and temperature affect the life cycle of a subtropical cockroach, Opisoplatia orientalis: seasonal pattern shaped by winter mortality

    Abstract Opisoplatia orientalis is an ovoviviparous cockroach living in the subtropical areas in Japan. Both adults and nymphs overwinter on Hachijo Island (33°N). The nymphs sampled before and after overwintering showed a similar pattern in frequency distribution of head widths with a definite peak of fifth instars. The present study was conducted to determine how this pattern was formed by investigating the effects of photoperiod and temperature on development and reproduction. Photoperiod influenced the number of nymphal instars, resulting in a longer duration of nymphal development at LD 12 : 12 h than at LD 16 : 8 h. However, the rate of development at each instar was only affected to a small extent by photoperiod and no sign of diapause was detected. It was suggested that the photoperiodic response controlling the number of nymphal instars might have evolved to adjust the timing of adult emergence and reproduction to the favourable season. The prereproductive period and time intervals between nymph depositions were prolonged as temperature declined, but there was no evidence for diapause in adults. Mortality occurred in eggs and embryos inside of the body of the females during winter. Thus, it was inferred that female adults would reset ovarian development in spring and deposit nymphs in summer simultaneously, and these nymphs would reach the fifth instar before winter comes. This winter mortality hypothesis was supported by experiments in which reproductive activity and mortality were monitored for field-collected adults under either constant or changing temperature conditions simulating those in the field.

    Abstract In order to achieve long-pulse H-mode plasma scenario over 400 s with high heating power in the Experimental Advanced Superconducting Tokamak (EAST) device, the lower graphite divertor will be upgraded into a tungsten (W) divertor with active water cooling, which consists of the W/Cu monoblock units and the W flat-tile units as the divertor plasma facing components. As a fundamental diagnostic tool, the divertor Langmuir probe (Div-LP) diagnostic system will be upgraded accordingly. This paper presents the design of two kinds of new Div-LP systems, which are planned to be utilized on the W/Cu monoblock units and the W flat-tile units for the upgraded lower tungsten divertor, respectively, including their structures and preliminary poloidal and toroidal layouts. The Div-LP diagnostic system can measure the plasma parameters with the schemes of triple-probe, double-probe, and single-probe, to obtain the spatial and temporal distribution of plasma behavior on the divertor targets, which is useful for the discharge control and operation in EAST. In addition, the thermal analysis of the two kinds of probe assemblies is also carried out by using the three-dimensional finite element code ANSYS, which is aimed to get the optimal designs to withstand the long-pulse and high-power operation in EAST future experiments.

    Abstract The migratory locust, Locusta migratoria Linne, shows not only prolonged copulation but also prolonged precopulatory associations between males and females. To understand the evolutionary significance of these behaviors, sperm competition success, measured by the P2, (i.e., the proportion of offspring sired by the second male to mate), was analyzed using the genetic marker albino. The precopulatory behavior has been proposed to guard a female or ensure timely mating. We report here that precopulatory mounting has a function other than guarding or just waiting in this locust: prolonged precopulatory mounting increases the length of copulation, which in turn increases the P2. Lengths of precopulatory mounting and copulation, as well as nearly absent postcopulatory mounting, were little influenced by the presence of a rival male. The observed large variation in P2 indicates that previously proposed mechanisms for sperm competition are not mutually exclusive, but all could occur in this species.

    Abstract A reversed-phase HPLC method for the determination of phenazine-1-carboxylic acid (PCA) in antifungal agent M18 is established. The mobile phase was a mixture of MeOH-5 mmol/L phosphate buffer (pH 5.0) (60:40, volume ratio). The flow rate was 1.0 mL/min, and the detection wavelength was 248 nm. The linear range and detectable limit were 50 mg/L-500 mg/L and 30 mg/L respectively. The recovery was 97.53% and RSD was 1.5%. The method of PCA extraction and detection has proven to be much faster, simpler, more sensitive, accurate and reproducible than those reported already. The assay results can be used as a very important criterion for large-scale production.
