Background
Large-scale protein interaction maps provide a new, global perspective with which to analyse protein function. PSIMAP, the Protein Structural Interactome Map, is a database of all the structurally observed interactions between superfamilies of protein domains with known three-dimensional structure in the PDB. PSIMAP incorporates both functional and evolutionary information into a single network. 相似文献3.
Laboratory experiments were carried out to investigate byssal thread production by the intertidal mytilid mussel Hormomya mutabilis in response to effluent from the predatory crab Eriphia smithii and the starfish Coscinasterias acutispina. During the early period of the experiment, large H. mutabilis exposed to crab effluent produced a significantly smaller number of functional byssal threads than mussels in crab-free water.
No significant difference in the diameter of threads produced in the two treatments was detected. The number of functional
byssal threads produced by small H. mutabilis exposed to crab effluent did not differ significantly from that of mussels in crab-free water. However, small H. mutabilis exposed to crab effluent tended to discard fewer byssal bundles, that is, they shifted their attaching sites less frequently
than similar mussels in crab-free water. In the presence of waterborne cues from the crab, H. mutabilis tended to reduce both the secretion of byssal threads and movement across the substratum. No significant differences in behaviour
were observed between large mussels exposed to effluent from the starfish and those unexposed. The adaptive significance of
the responses shown by H. mutabilis is discussed in terms of protection against predators differing in foraging behaviour.

本文首次采用田间试验的方法对国内油菜收获指数的变异进行了研究.结果表明不同油菜品种的收获指数存在变异,其变异规律大致是:1)中熟品种的收获指数高于早熟品种及晚熟品种;2)中长角果的品种较长角品种具有更高的收获指数;3)高产的新品种具有较高的收获指数;4)油菜粒壳比,角杆比及千粒重与收获指数呈正相关,杆重与收获指数呈负相关. 相似文献
