OsEBP-89 gene encodes an ethylene responsive element binding protein (EREBP) transcription factor from rice (Oryza sativa). Northern blot analysis revealed that OsEBP-89 was expressed in root, stem, seeds, flowers and leaves. Histochemical assay showed that β-glucuronidase (GUS) was expressed mainly in phloem of vascular tissues of the root and stem transition region (RST), basal part of sheath roots, stem node and basal part of adventitious roots, also in endosperm of seeds in transgenic rice harboring OsEBP-89/GUS construct (pNSG). A sequence region from -2.9 to -97 was found to play an important role for OsEBP-89 gene expression through promoter deletion assay. The possible function of OsEBP-89 gene was discussed.

Rice (\%Oryza sativa\% cv. Jindao 1187) was grown in open_top chambers which contained ambient and enriched CO\-2. CO\-2.elevation stimulated rice tillering during early vegetative stage. However, panicle dry weight per plant did not change at maturity stage. Root biomass was enhanced by high CO\-2. Root / shoot ratio was increased under high CO\-2.at maturity, indicating more carbon allocation to the below_bround part in rice under high CO\-2.

Based on Quick Bird satellite image data, the present study examined small-scale herbaceous community patches in the marsh of the Sanjiang Plain and measured patch characteristics such as the area, perimeter and shape by GPS. The coenological characteristics of the patches were investigated using quadrat method, and the vascular plant species were recorded using transect method. A total of 2.9 plant species were recorded, which represents 12.2. of the vascular flora in Heilongjiang Province. Our results showed that species number S correlated with patch area and perimeter; richness index (R) correlated with patch perimeter; Simpson index (D) correlated with patch area and perimeter/area; Shannon-Wiener index (H′) correlated with patch area, perimeter and perimeter/area; Evenness index (Jsw) correlated with perimeter/area. Both S and R have significant difference between different size of patches. plant diversity in the small-scale herbaceous communities tended to increase with the patch area and perimeter. We concluded that edge effects and the habitat heterogeneity of the patches are important in determining the number of species. The relative smoothness of the patch edges also affects the plant diversity of the patches. The richness of plant species in the marsh in the Sanjiang Plain is highly sensitive to the small-scale patches, which continues to play an important role in preserving plant diversity in the local area.

The rice clustered spikelets (Cl) mutant exhib-its a phenotype that most of branch apical have 2.3 spikelets clustered together. SEM (scanning electron microscope) ob-servation suggested that the Cl gene controlled branch apical development, and influenced the terminal spikelets elonga-tion. The spikelet number was reduced in mutant, indicating that Cl may also have an effect on spikelet number. To map Cl locus, two F2.mapping populations derived from the crosses between the Cl and ZhongHua11, and Cl and ZheFu802.were constructed, respectively. The Cl locus was roughly mapped between two CAPS markers, CK02.4 and SS032.. A further fine mapping analysis showed that the Cl locus was mapped between makers R0674E and Cl2.60, with genetic distances of 0.2.and 2.1 cM, respectively. Then we found a PAC contig spanning Cl locus, the region was delim-ited to 196 kb. This result was useful for cloning of the Cl gene. Allelism test demonstrated that Cl was allelic to Cl2. another rice clustered spikelets mutant.

As natural tracers, stable isotopes have been extensively used in plant physiological, ecological and envi- ronmental research. Recently, animal physiological ecologists have also applied stable isotope techniques to study plant- animal relationships. The isotopic compositions of animal body generally reflect and integrate their diets over a time period ranging from hours to years to the lifetime of an indi- vidual. When animal living habitat changes or animals move to a new environment, the animal isotopic compositions will shift accordingly. Thus, stable isotope signatures of an ani- mal can truly reflect its food sources, habitat, distribution and movement patterns during a given time period. More- over, by analyzing animal-tissue isotopic compositions at different temporal scales, we can improve our understanding of animal adaptation to environmental changes. Stable iso- tope technique also provides an ideal tool to study animal foodweb relationship and community structure because of isotopic fractionation during the processes of nutrient as- similation by animals. Stable isotope technique can continu- ously measure animal trophic position in a foodweb, which can eventually reveal the predator-prey relationship and its role in determining matter balance and energy flow in the entire ecosystem. Stable isotope technique has been one of the most important and efficient tools in studying plant-animal relationship. In this paper, we first review recent advances in the application of stable isotope techniques to plant-animal relationship research then evaluate their advantages and disadvantages, and finally discuss some future directions associated with stable isotope applications to plant-animal relationship research.

Immature embryos of rice varieties 'Xiushui11' and 'Chunjiang 11' precultured for 4d were infected and transformed by Agrobacterium tumefaciens strain EHA101/pExT7 (containing the spider insecticidal gene). The resistant cant were transferred onto the differentiation medium and plants were regenerated. The transformation frequency reached 56%-72. measured as numbers of Geneticin (G418)-resistant calli produced and 36%-60% measured as numbers of transgenic plants regenerated, respectively. PCR and Southern blot analysis of transgenic plants confirmed that the T-DNA had been integrated into the rice genome. Insect bioassays using T1 transgenic plants indicated that the mortality of the leaffolder (Cnaphalocrasis medinalis) after 7d of leaf feeding reached 38%-61% and the corrected mortality of the striped stem borer (Chilo suppressalis) after 7d of leaf feeding reached 16%-75%. The insect bioassay results demonstrated that the transgenic plants expressing the spider insecticidal protein conferred enhanced resistance to these pests.
