Abstract	A new rice semidwarfing gene which is not allelic tosd1, temporarily designated assdg, might be of use as a new source of semidwarfism in rice breeding programs. We report here the identification of a DNA marker closely linked to this gene. The DNA marker was identified by testing 120 mapped rice RFLP makers as hybridization probes for Southern analysis of a pair of nearly isogenic lines with or withoutsdg. Linkage association of the marker with the gene was verified using a F2 population segregating for semidwarfism. RFLP analysis showed thatsdg is closely linked to a single-copy DNA clone RZ182 on chromosome 5, with a distance of 4.3 centiMorgans between them. This marker may facilitate early selection for the semidwarfing gene in rice breeding programs.

Abstract	Soluble starch synthase II (SSII) plays an important role in the biosynthesis of starch and in rice it consists of three isoforms encoded by SSII-1, SSII-2 and SSII-3. However, the genetic effects of various SSII alleles on grain quality have not been systematically characterized. In the present study, the japonica alleles on SSII-1, SSII-2 and SSII-3 (SSIIa) loci from a japonica cultivar, Suyunuo, were respectively introgressed by molecular marker-assisted selection into a typical indica cultivar, Guichao2, through successive backcrossing, generating three sets of near-isogenic lines (NILs). Grain quality and starch property analysis showed that NIL-SSII-3ʲ exhibited significant decreases in the following parameters: amylose content, average granule size, and setback viscosity and consistency; but increases in peak viscosity, hot paste viscosity, gelatinization temperature and relative crystallinity. Moreover, the proportion of short amylopectin chains and branching degree also increased when compared with those of NIL-SSII-3ⁱ (Guochao2). Similar effects were observed in NIL-SSII-1ʲ, and certain alterations in the fine structure of starch (granule size) were revealed. However, NIL-SSII-2ʲ did not exert significant effect on grain quality and starch properties. In brief, among the SSII gene family, the functional diversity occurred on SSII-1 and SSII-3, and not on SSII-2. Therefore, it appears that more attention should be directed to SSII-1 and SSII-3 loci for improving the eating and cooking quality of rice.

Abstract	Background: Combined dexamethasone and tropisetron have been reported more effective than a single drug therapy in preventing postoperative nausea and vomiting (PONV). However, the safety use of dexamethasone has been questioned recently because of the risk of secondary adrenal deficiency. Therefore, we hypothesized that combined tropisetron and methylprednisolone, a short-lasting corticoid, might provide effective prophylaxis of PONV with less effect on endogenous cortisol level. Methods: In this study, 224 women undergoing modified radical mastectomy under general anesthesia were randomly divided into three groups: 1) receiving 10 mg tropisetron alone (T, N.=76); 2) 10 mg tropisetron and 8 mg dexamethasone (TD, N.=73); or 3) 10 mg tropisetron and 40 mg methylprednisolone (TM, N.=75) intravenously. Serum cortisol level, episodes of PONV and the need for rescue antiemetic medication were recorded during first 3 days after surgery. Results: Serum cortisol significantly decreased in group TD (5.42±1.87 μg/dL), compared with group TM (14.38±2.01 μg/dL, P<0.01) and group T (19.52±1.53 μg/dL, P<0.001) in the first day postoperatively. In the first 24 hours, the incidence of vomiting was significantly higher in group T (15.8%), compared with group TD (5.5%, P<0.05) and group TM (5.3%, P<0.05), respectively. The overall request for a rescue antiemetic of group T was significantly higher, compared with group TD and group TM (P<0.05). Conclusion: Methylprednisolone-tropisetron combination is more effective than tropisetron alone, and as equally effective as dexamethasone-tropisetron combination for preventing acute PONV in mastectomy.

Abstract	Dular is one of the typical wide compatibility varieties in ecotype Aus of rice. Genetic analysis on wide compatibility genes (WCG) from Dular based on triple crosses (indica//++Dular/japonica) was conducted. In the condition of being shaded for 7 days, the individual spikelet fertility segregated obviously, and the continuous distributions of spikelet fertility with a handful of peaks were observed. This suggested that the segregation of spikelet fertility in triple cross populations was controlled by one or more major genes, also modified by some minor genes. Based on 109 individuals of triple cross Nanjing 11 (indica)//++Dular/2533(japonica, a marker gene line, Rc and g), fertile and semisterile pools were set up by bulked segregant analysis, the RFLP analysis of the two pools led to the discovery of three chromosomal segments co-segregating with fertility. The one is on the interval RG213-C235 on chromosome 6. According to the previous studies, it may be the wide compatibility gene S5n. The other two were on the interval RG901-RG413 and G402-RG651 on chromosome 12, temporarily designated as Sd1(t)n and Sd2(t)n, respectively. Because of the continuous distribution for spikelet fertility, we also used a quantitative model to evaluate the effects of those three loci. On the basis of interval analysis with Mapmaker/QTL, 32.3% of the phenotypic variance associated with spikelet fertility was explained by the S5n (LOD = 9.03), and the other two chromosomal segments were responsible for 10.5%(LOD = 2.61) and 10.9%(LOD = 2.14) phenotypic variance, respectively. The results demonstrated that the wide compatibility variety Dular contained three WCGs. To introgress the three WCGs into a restorer line or an abortive line will overcome the hybrid sterility barrier of indica/japonica crosses, and the precise RFLP mapping will be useful for breeders to accumulate a few genes of interest into one cultivar by means of molecular marker assisted selection.

Abstract	A sterile variant was found from the population of a japonica rice variety Lunhui 422. Cytological investigation was conducted in meiosis. It is showed that the sterility was caused by desynapsis. As there were 8.69 bivalents in average occurred to be desynaptic, moreover, the most number of the desynaptic bivalents reached 12 at post diakinsis. It can be considered that the desynaptic variation is a complete desynapsis found in rice so far.

Abstract	Utilization of heterosis between rice subspecies has fascinated rice breeders for several decades. One of the main obstacles is the hybrid sterility in the F1 populations of subspecies crosses in rice. Wide compatibility varieties are considered to an important way to overcome the problem. But the genetics of the wide compatibility is controversial. This paper dealt with the problem through three kinds of triple crosses in which a wide compatibility variety, Ketan Nangka, was involved. Pollen fertility, spikelet fertility and the correlationship between the two fertilities were analyzed in the three kinds of triple crosses. The results suggested that male and female sterilities existed in indica-japonica hybrids at the same time, while the contribution of male sterility to spikelet fertility varied from cross to cross; The characteristic of wide compatibility in different triple crosses was coordinated with the hybrid sterility between the indica and japonica test varieties used; Ketan Nangka possessed the wide compatibility genes on the loci in which the male and female sterilities between the test varieties were involved; The genetics of wide compatibility gene S-5 fitted to one locus sporo-gametophytic interaction model.

Abstract	RFLP markers were employed to test whether the individuals possess wide compatibility genes (WCGs) in the progenies of Dular, which is one of the typical wide compatibility varieties in ecotype Aus rice. Meanwhile the characteristics of WCGs were also analysed. The results are shown as follows: (1) the effect of WCG at S-5 locus is better than the others, (2) the combination of different wide compatibility loci is obviously effective in increasing the spikelet fertility, (3) intraallelic interaction can cause japonica macrospore abortive, while interallelic interaction has some effects in fertility expression.
