Molecular identification and function characterization of four alternative splice variants of trim25 in Japanese flounder (Paralichthys olivaceus).

Trim25 is a member of Tripartite Motif (TRIM) family. Previous studies report that trim25 modulates antiviral activity by activating RIG-I. In this study we explored the four alternative splicing (AS) variants X1-X4 of Japanese flounder trim25.

[Vertical distribution patterns of nitrogen, phosphorus, and potassium in Chinese pine forest soils developed from different parent materials in Songshan Mountain Nature Reserve, Beijing of China].

Taking the soils developed from two kinds of parent materials (granite and limestone) under Pinus tabulaeformis forest at the same altitude in Songshan Mountain Nature Reserve of Beijing as test objects, this paper studied the vertical distribution patterns of soil total nitrogen, available phosphorus, and available potassium. The soil developed from granite had the total nitrogen, available phosphorus, and available potassium contents being 1.61-2.

[Effects of water-nitrogen coupling on leaf nutrient contents of triploid Populus tomentosa clone BT17].

To understand the coupling effect of water and nitrogen on the leaf nutrient contents of Populus tomentosa and to search for an optimal combination of water and nitrogen for P. tomentosa, a field experiment with randomized block design (3 levels of irrigation water and 4 levels of fertilizer nitrogen) was conducted in a two-year-old P. tomentosa clone BT17 plantation in the nursery of Weixian County, Hebei Province of North China from 2007 to 2009.
