| 1 | Mapping of Fertility Restoring Gene for Aegilops kotschyi Cytoplasmic Male Sterility in Wheat Using SSR Markers显示文摘LK783 was found to be a good fertility restorer for K-type male sterility of wheat. Microsatellite markers were employed to map the major restoring gene in LK783. Maintainer and restorer DNA pools were established using the extreme sterile and fertile plants among (KJ5418A//911289/LK783)F1 population,respectively. Seventy-nine sets of SSR primers were screened for polymorphism between the two pools, 6 of which were found polymorphic. Linkage analysis showed that Xgwm11, Xgwm18 , Xgwm264a and Xgwm273were linked to the restoring gene in LK783, while Xgwm11, Xgwm18 and Xgwm273 were co-segregated. The distance between the Rf gene in LK783 and the three co-segregated markers was 6.54±4.37 cM, the distance between Rf gene and Xgwm264a was 5.71±4.10 cM. The four SSR markers were located on chromosome 1BS by amplifying the DNA of nulli-tetrasomics and ditelosomics of CS with the 4 sets of primers, indicating that the major restoring gene in LK783 was located on 1BS, but the relative location of the gene was different from Rfv1, allelism of the two genes should be further investigated. The breeding for new fertility restorer lines of K-type cytoplasmic male sterility in wheat would be facilitated by using the four polymorphic markers. | LIU Bao-shen, SUN Qi-xin, GAO Qing-rong, SUN Lan-zhen, XIE Chao-jie, LI Chuan-you, NI Zhong-fu and DOU Bing-de( Agronomy Department, Shandong Agricultural University, Taian 271018, P.R.China Department of Plant Genetics and Breeding, China Agricultural University, Beijing 100094 , P.

| 2 | Studies on the Microscopic Mechanism of the Thermodynamic Stability of Pesticide Microemulsion显示文摘The cryo-fracture electron microscope was used to study the micro-structure of pesticide microemuisions. The hydromechanical radius (Rh) and the distribution (fRh) of pesticide microemulsions were determined by photo-correlation spectroscopy. This study showed that the Rh was significantly greater when the ratio of surfactants to water (w/w) decreased to 20/31 from 27/26, and a bicontinuous structure was formed when the ratio dropped to 15/36. These results explained the relationship between pesticide properties and the microscopic structure, and provided a good method for studying the microscopic structure of pesticide formulations. | HUANG Qi-liang, YUAN Hui-zhu and YANG Dai-bin(Institute for Plant Protection , Chinese Academy of Agricultural Sciences , Beijing 100094 , P.

| 3 | The Maturation and Senescence in Relation to Ca^2+,CaMContent and Ca^2+-ATPase Activity and Active OxygenMetabolism in Strawberry Fruits显示文摘The changes in content of Ca2 + and CaM, Ca2 + -ATPase activity and active oxygen metabolism during strawberry (Fragaria ananassa Duch. cv. Chunxing) fruits maturation and senescence were investigated in this study. The results showed that the soluble Ca2 + content and SOD activity in fruits tended to decline and O2.-production rate to increase, the Ca2+ -ATPase activity peaked at first and then declined during fruits maturation and senescence. There were the highest CaM content at white stage in preharvest fruits and at marked senescence stage in postharvest ones. The above biochemical changes in fruits stored at low temperature (4℃) were slower than those stored at normal temperature(25℃ ). Thus, it indicated that the stimulation of calcium messenger system and accumulation of active oxygen free radical were closely related to fruits maturation and senescence. | GUAN Jun-feng, GAO Min, FAN Xiu-cai, GU Cai-qin, LI Guang-min and ZHANG Ji-shu(Institute of Agro-Physics , Plant Physiology and Biochemistry , Hebei Academy of Agricultural and Forestry Sciences ,Shijiazhuang 050051 , P.

| 4 | Study on the Ultrastructures of Antennal Sensilla in Helicoverpa armigera显示文摘The morphology and structures of antennal sensilla of Helicoverpa armigera are observed under scanning and transmission electron microscopes. Antennae of Helicoverpa armigera are made up of scapus,pedicel and flagellum that the latter consists of 70 - 82 segments. The inner side surface of antenna is cataphracted and most of the antennal sensilla lie on its outer, upper and lower surfaces. Both the antennae of male and female contain five kinds of antennal sensilla, namely, sensillum trichodeum, sensillum basiconicum, sensillum chaeticum, ear-shaped sensillum and sensillum coeloconicum, and the kinds, number and distribution of antennal sensilla of both sexes are similar. There are a large number of serrate cuticular processes on antennal surface, especially on the middle and basic parts of antenna. Sensillum trichodeum and sensillum basiconicum, the main chemical odor receptors on antennae of Helicoverpa armigera, consist of cuticularwall, sheath cells, lymph and dendrites. There are significant differences between the internal structures of the two kinds of sensilla. In sensillum trichodeum, the cuticular-wall is thicker, less lipophilic pore channels and has one or a few dendrites, while in sensillum basiconicum, the cuticular-wall is thinner, abundant lipophilic pore channels and has much more dendrites. | WANG Gui-rong, GUO Yu-yuan and WU Kong-ming( State Key Laboratory of Plant Disease and Insect Pests, The Institute of Plant Protection , Chinese Academy of Agricultural Sciences, Beijing 100094 , P.
