Lanzia berggrenii及其相关种的系统发育地位(英文)

系统发育分析结果表明,尽管Lanzia berggrenii能在寄主中形成基物子座,但与膜盘菌属的核心种关系较近,而与蜡盘菌科成员关系较远,应该归属于膜盘菌属。在广义的膜盘菌属的系统树中该种及在新西兰发现的4个新种构成一个单系群,分别命名为Hymenoscyphus haasticus,H. kiko,H.ohakune和H.waikaia。它们的共同特征:基物均为南青冈叶片,侧丝顶端分枝形成类似囊层被的结构,覆盖于子实层上部。Lanzia berggrenii var.metrosideri应为膜盘菌属中一个独立的种,即Hymenoscyphus metrosideri。     

谈谈子座和子实体

子座是某些高等真菌（主要是高等的子囊菌）的子实体下面或周围菌丝组成的紧密组织。也就是说,子座是容纳子实体的褥座（子座,名称stroma,希脂文,为褥垫、床之意）,常从菌核上发生,是真菌从营养阶段到繁殖阶段的一种过渡形式。而子实体是高等真菌产生抱子的结构。子囊果就是子囊菌的子实体,通常有子囊壳（如麦角病菌ClavicePsPurPurea）、子囊盘（如葱类小菌核病菌Sclerotiniaallii）、闭囊壳（如麦类白粉病菌Erysiphegraminis）3种类型。当菌核萌发时,首先形成子座（也有形成菌丝的,如丝核菌Rhizoctoniasolani）,在子座内着生…

Bipolar heterothallism,a principal mating system of<Emphasis Type="Italic">Cordyceps militaris in vitro</Emphasis>

Interest inin vitro study of entomopathogenic fungi, includingCordyceps species, has been increasing due to their valuable bioactive compounds and biocontrol effects. AmongCordyceps species,in vitro stromata ofC. militaris has been successfully produced and cultivated for industrial purposes. However, genetic study onin vitro stromata formation ofC. militaris has not been carried out yet. Here, relationship between mating system and perithecial stromata formation ofC. militaris is reported. Mating system was determined by observing perithecial stromata formation from mono-ascospore cultures and their pair-wise combinations. Certain combinations of mono-ascospore strains produced perithecial club-shaped stromata, whereas other combinations produced either no stromata or only abnormal non-perithecial stromata. Similarly, monoascospore cultures without combination produced either no stromata or only abnormal nonperithecial stromata. Despite obvious heterothallism, self-fertility was occasionally observed in few strains ofC. militaris. These observations indicated thatC. militaris behaves as a bipolar heterothallic fungus and requires two mating compatible strains in order to produce regular clubshaped perithecial stromata, a fundamental requirement for its industrial cultivation.

Attempt to isolate antierythrocyte antibodies by the method of affinity chromatography. I. IgM--complete antibodies

It follows from the results of the present study that erythrocyte stromata can serve as a suitable insoluble immunosorbent of complete antibodies. When using optimum conditions, such as laboratory incubation timperature, suitable buffers for both washing the column prior to absorption and for elution, it is possible to obtain, by means of the chromatographic column with 0.5 ml of erythrocyte stromata suspended in 40 g of silica glass beads (ballotini), fractions devoid of complete antibodies and subsequently to obtain the latter in purified form by elution. In complete anti antibodies, the elution yield amounted to an average of 35% of the initial amount of antibodies. Although the elution yield is not high and non-specific absorption has been demonstrated, the method can be recommended for the isolation of complete antibodies and thus for the production of monospecific sera because it is easy, rapid and inexpensive due to the regeneration ability of the mentioned columns and the relatively long duration of the immunoabsorption capacity of the incorporated erythrocyte stromata.

Obolarina persica sp. nov., associated with dying Quercus in Iran

Improved method for the isolation and preliminary characterization of human DAF (decay-accelerating factor)

DAF (decay-accelerating factor) is one of the integral membrane proteins of erythrocytes, and is considered to play an important role in the regulation of complement activation. The purification of DAF has been impeded by the difficulty in removing glycophorin. We devised an effective method for removing glycophorin. Through the limited trypsinization of stromata prior to the extraction of DAF, glycophorin was readily digested so that the DAF could be purified free of glycophorin by DEAE-Sephacel and Bio-Gel A 0.5 m chromatographies. On SDS-PAGE, DAF from trypsinized stromata showed the same mobility as that from native stromata: its molecular weight was estimated to be about 70 kDa. Amino acid analysis of DAF showed high contents of serine and glutamic acid. The amino-terminal sequence of DAF prepared by the present method, determined for the 29 residues, did not show significant homology with that of glycophorin.

Theissenia rogersii sp. nov. and phylogenetic position of Theissenia

Theissenia rogersii deviates from known Theissenia species primarily in having large ascospores with a thick wall layer and a unique configuration of two stromatal tissue types, one carbonaceous and the other fibrous. The carbonaceous tissue forms palisades on and beneath the perithecial layer as well as encasing individual perithecia, whereas the fibrous tissue fills the spaces between columns of the palisades as well as between encased perithecia. Phylogenetic analyses based on DNA sequences of beta-tubulin and alpha-actin genes placed Theissenia in the subfamily Hypoxyloideae among the genera that are characterized by having bipartite stromata (i.e. with the stromata differentiated into an outer dehiscing layer and an inner perithecium-bearing layer).     

ENDOPHYTE-HOST ASSOCIATIONS IN FORAGE GRASSES. XV. CLUSTERING OF STROMATA-BEARING INDIVIDUALS OF AGROSTIS HIEMALIS INFECTED BY EPICHLOË TYPHINA

Population studies involving the grass Agrostis hiemalis infected with the endophytic fungus Epichloë typhina were made. Grass individuals were assessed for infection state (presence or absence of fungus), number of culms and fungal stromata, and location within plot. Using clustering and ANOVA procedures available in SAS, geometric groups were identified and analyzed. The tendency of plants to bear stromata was found to be significant with respect to both the plot (P < 0.05) and the cluster (P < 0.0001) within which plants occurred. A cultural study was made of the endophytes from one of the plots. Here isolates from a cluster containing stroma-bearing grass individuals were found to grow more rapidly than those from grass clusters without stromata on a variety of sugars naturally available in vivo. Histological studies of the host demonstrate that the endophyte is seed transmitted in a comparable fashion to endophytes in other grasses. It is suggested that the clustering of stromata-bearing plants in Agrostis hiemalis is the result of the presence of aggressive strains of endophyte within proximally located plants.     

QUANTITATIVE CHEMICAL STUDIES ON HEMOLYSINS : I. THE ESTIMATION OF TOTAL ANTIBODY IN ANTISERA TO SHEEP ERYTHROCYTES AND STROMATA

1. Total antibody in hemolysins may be estimated from the nitrogen added to sheep stromata suspensions. 2. The method is applied to a number of hemolysins and a correlation, valid to within 20 per cent, established between hemolytic titer and total antibody. 3. When stromata combine with antibody in the presence of guinea pig complement they may take up at least 80 per cent of their weight of complement combining component(s).
