本文描述了采自海南省琼中县牛紏吴茱萸Evodia trichotoma (Lour.) Pierre(芸香科)上的柄锈菌一新种——Puccinia evodiae-trichotomae J. -y. Zhuang。本种与巴布亚一新几内亚产的吴茱萸Evodia sp.上的另一种柄锈菌Puccinia evodiae Cumm.略近似,但冬孢子堆裸露呈垫状,而后者则深埋于病瘿中。冬孢子形状与大小和后者相仿,然而少数孢子可长达60μm,顶壁有时略增厚,颜色很浅或近几色。镜下可见一些孢子已萌发,推测可能属无眠冬孢型。芸香科植物上的柄锈菌目前仅知10种,本种特征与它们均不相同,故鉴定为新种。本新种模式标本保藏在中国科学院微生物研究所真菌标本室。 相似文献

In experiments on Black Sea skates (Raja clavata), the potential of the receptor epithelium of the ampullae of Lorenzini and spike activity of single nerve fibers connected to them were investigated during electrical and temperature stimulation. Usually the potential within the canal was between 0 and –2 mV, and the input resistance of the ampulla 250–400 k. Heating of the region of the receptor epithelium was accompanied by a negative wave of potential, an increase in input resistance, and inhibition of spike activity. With worsening of the animal's condition the transepithelial potential became positive (up to +10 mV) but the input resistance of the ampulla during stimulation with a positive current was nonlinear in some cases: a regenerative spike of positive polarity appeared in the channel. During heating, the spike response was sometimes reversed in sign. It is suggested that fluctuations of the transepithelial potential and spike responses to temperature stimulation reflect changes in the potential difference on the basal membrane of the receptor cells, which is described by a relationship of the Nernst's or Goldman's equation type.I.

Evolution of living organisms is closely connected with evolution of structure of the system of regulations and its mechanisms.
The functional ground of regulations is chemical signalization. As early as in unicellular organisms there is a set of signal
mechanisms providing their life activity and orientation in space and time. Subsequent evolution of ways of chemical signalization
followed the way of development of delivery pathways of chemical signal and development of mechanisms of its regulation. The
mechanism of chemical regulation of the signal interaction is discussed by the example of the specialized system of transduction
of signal from neuron to neuron, of effect of hormone on the epithelial cell and modulation of this effect. These mechanisms
are considered as the most important ways of the fine and precise adaptation of chemical signalization underlying functioning
of physiological systems and organs of the living organism 相似文献
