Differential selection on gene translation efficiency between the filamentous fungus Ashbya gossypii and yeasts

Background: The filamentous fungus Ashbya gossypii grows into a multicellular mycelium that is distinct from the unicellular morphology of its closely related yeast species. It has been proposed that genes important for cell cycle regulation play central

Phomoeuphorbins A-D, azaphilones from the fungus Phomopsis euphorbiae

Four azaphilones, named phomoeuphorbins A-D (1-4) were isolated from cultures of Phomopsis euphorbiae, an endophytic fungus isolated from Trewia nudiflora. Structures of 1-4 were established on the basis of spectroscopic analyses, including application of

黄土塬区果园套种对土壤微生物及酶活性的影响

研究了黄土塬区塬面不同套种作物的幼树苹果园土壤微生物的分布和酶活性。结果表明，果园土壤中微生物的分布在果树行与套种行中是不均匀的，细菌和真菌多为果树行多于套种行；土壤的过氧化氢酶，蔗糖酶，脲酶以及中性磷酸酶活性在套种小麦的果园中以套作行高于果树行，而套种烤烟则使脲酶和中性磷酸酶活性有所降低。套种豆类有利于土壤肥力的均衡发展。
