- Knockdown of a putative Halloween gene Shade reveals its role in ecdysteroidogenesis in the small brown planthopper Laodelphax striatellus.
- Jia S, Wan PJ, Zhou LT, Mu LL, Li GQ.Author information Education Ministry Key Laboratory of Integrated Management of Crop Diseases and Pests, College of Plant Protection, Nanjing Agricultural University, Nanjing 210095, China.AbstractEcdysteroid hormone 20-hydroxyecdysone (20E) plays fundamental roles in insect development and reproduction, whereas the primary role of ecdysone (E) is the precursor for 20E. A cytochrome P450 monooxygenase (CYP), encoded by a Halloween gene Shade (Shd, cyp314a1), catalyzes the conversion of E into 20E in representative insect species in Diptera, Lepidoptera and Orthoptera. We describe here the cloning and characterization of LsShd in a hemipteran insect species, the small brown planthopper Laodelphax striatellus. LsSHD has five insect conserved P450 motifs, i.e., Helix-C, Helix-I, Helix-K, PERF and heme-binding motifs. Temporal expression pattern of LsShd was determined through the fourth-instar and the early fifth-instar stages by qPCR. LsShd showed two expression peaks in day 2 and day 5 fourth-instar nymphs, and two troughs in day 1 fourth and fifth instars. Dietary introduction of double-stranded RNA (dsRNA) of LsShd into nymphs successfully knocked down the target gene, decreased expression level of ecdysone receptor (LsEcR) gene, and caused nymphal lethality and delayed development. Ingestion of 20E did not increase LsShd expression level, but almost completely rescued LsEcR mRNA level, and relieved the negative effects on the survival and development in LsShd-dsRNA-exposed nymphs. In contrast, dietary introduction of E had little rescue effects. Thus, our data suggest that the ecdysteroidogenic pathway is conserved in insects, and LsSHD functions to regulate metamorphotic processes by converting E to 20E even in a hemipteran insect, L. striatellus.

- Structural and experimental investigations of the functional anatomy and the turgor of the notochord in the larval tail of anuran tadpoles.
- Platz F.Author information Institute of Anatomy and Cell Biology, Department of Neuroanatomy, University of Freiburg, Albertstr. 17, D-79104 Freiburg, Germany. giselind.adelmann@anat.uni-freiburg.deAbstractThe premetamorphotic morphology and metamorphotic degeneration of the tail notochord of anuran tadpoles has been investigated. For this purpose the functional anatomy and origin of the notochord turgor was analysed in 10 species macroscopically and using light, transmission and scanning electron microscopic techniques. The notochord consists of the fibrous notochord sheath, which surrounds the notochord cells. Within the sheath these cells form a net-like unit. The inner cells are derived from the marginal notochord cells (chordoblasts). They are protected from mechanical overload by intracellular filaments and desmosomes. Due to their vacuoles, which are filled with a hyaline liquid, they have a constant volume but are deformable. Dissolved substances may pass from the vascularized fin to the notochord cells. The transport from marginal to inner cells occurs via cytopempsis and micropinocytosis. The morphological correlation of this process consists of multiple membrane invaginations and intracellular vesicles. Within the notochord cells a high turgor pressure has been observed. During metamorphosis the membrane vesiculation persists and the notochord cells degenerate. Due to the loss of turgor pressure the tight consistency of the notochord is lost. The collagen filaments and the elastic membrane of the notochord sheath dissolve. Notochord cells with their filaments, high turgor pressure and their central vacuole can function as a combined mechanical and physiological system, which is adaptable to the needs of pressure, compression, tensile and bending forces.

- [Dynamic changes of ultrastructure of erythrocytes in prolonged preservation at 4 degrees C].
- Ren SP, Ma EP, Liu XZ, Han Y, Liu A, Jin P.Author information Beijing Institute of Blood Transfusion, Beijing 100850, China. rensuping@hotmail.comAbstractTo study the dynamic changes of ultrastructure of erythrocytes in prolonged preservation of blood with preservative fluid containing superoxide dismutase (SOD), the whole blood samples were preserved at 4 degrees C in SOD-containing solution, the morphologic changes of erythrocyte were dynamically ob served by transmission microscopy after preservation for 42, 75 and 85 days, an d the blood samples preserved in GMA solution served as control. Three variance was applied to analyze the data with SAS software. The results showed that the metamorphotic rates of erythrocyte preserved in SOD-containing solution for 42, 75 and 85 days were lower than those of erythrocytes preserved in GMA solution. Most of metamorphotic rates of erythrocyte preserved in SOD-containing solution for 42, 75 and 85 days were correspond to those of erythrocytes preserved in GMA solution for 42 days, or even lower. It is concluded that SOD-containing preservative fluid might help to maintain the normal morphology of erythrocytes in prolonged preservation at 4 degrees C.
