OsUVR8b, rather than OsUVR8a, plays a predominant role in rice UVR8-mediated UV-B response.

UV RESISTANCE LOCUS 8 (UVR8) has been identified in Arabidopsis thaliana as the receptor mediating responses to UV-B radiation. However, UVR8-mediated UV-B signaling pathways in rice, which possesses two proteins (UVR8a and UVR8b) with high identities to AtUVR8, remain largely unknown. Here, UVR8a/b were found to be predominantly expressed in rice leaves and leaf sheaths, while the levels of UVR8b transcript and UVR8b protein were both higher than those of UVR8a.

[Mechanisms Involved in the Inhibition of Melanin Synthesis by Bushen Quban Granule].

Objective To observe the molecular mechanism of Bushen Quban Granule (BQG) for inhibiting the synthesis of intracellular melanin. Methods Twenty SPF grade female SD rats were di- vided into four groups by completely randomized method, i.e.

Elevated growth differentiation factor 15 expression predicts poor prognosis in epithelial ovarian cancer patients.

The purpose of this study was to determine the expression of growth differentiation factor 15 (GDF15) and explore its clinical significance in epithelial ovarian cancer (EOC) patients. The expression of GDF15 in EOC tissues and serum samples was evaluated using immunohistochemistry and enzyme-linked immunosorbent assay (ELISA), respectively. The association of GDF15 expression with clinicopathologic parameters was analyzed.

[Carbon storage of forest stands in Shandong Province estimated by forestry inventory data].

Based on the 7th forestry inventory data of Shandong Province, this paper estimated the carbon storage and carbon density of forest stands, and analyzed their distribution characteristics according to dominant tree species, age groups and forest category using the volume-derived biomass method and average-biomass method. In 2007, the total carbon storage of the forest stands was 25. 27 Tg, of which the coniferous forests, mixed conifer broad-leaved forests, and broad-leaved forests accounted for 8.

[Ecosystem's soil conservation function and its spatial distribution in Lancang River Basin, Southwest China].

Based on the RUSLE model, this paper analyzed the ecosystem's soil conservation function and its spatial distribution in Lancang River Basin. This Basin could be one of the regions having the highest ecosystem' s soil conservation capability in China, with an annual ecosystem's soil conservation amount being 2.36 x 10(10) t x a(-1) and the soil conservation amount per unit area being 1453.
