A new species ofNeosartorya, N. sublevispora (anam.Aspergillus sublevisporus), is described and photographed. The species is characterized by non-ostiolate ascomata covered loosely with a pale yellowish
hyphal envelope, lenticular ascospores with two low equatorial crests, and subglobose to ellipsoidal, microtuberculate conidia.
The ornamentation of ascospores, which is composed of two closely appreassed crests and small even-sized echines on their
convex surfaces, particularly serves to distinguish this species from other recognized species. A revised key to all accepted
species of the genus is provided. 相似文献

Aspergillus caatingaensis and A. pernambucoensis, isolated from semi-desert soil in caatinga area, the State of Pernambuco, Brazil, are described and illustrated. Aspergillus caatingaensis is characterized by its white cleistothecia, broadly lenticular ascospores with four equatorial crests and irregularly ribbed to slightly reticulate with aculeate convex surfaces, and ellipsoidal to broadly ellipsoidal conidia with a smooth wall. Aspergillus pernambucoensis is characterized by its, white cleistothecia, lenticular ascospores with two equatorial crests and irregularly ribbed with tuberculate to verrucate convex surfaces, and ovoid to broadly ellipsoidal conidia with a smooth wall. The validation of these new species is supported further by analyses of the β-tubulin, calmodulin and actin gene sequences. 相似文献

Two new species, Neosartorya shendaweii and N. tsunodae, isolated from soil in Xinjing, China and in Pernambuco, Brazil, are described and illustrated. The first species is characterized
by its ascospores with two widely separated equatorial crests and tuberculate to verrucose convex surfaces. This species has
affinities with several known species of the genus, bearing ascospores with a similar ornamentation, but can be distinguished
from these species by other morphological characteristics such as smaller cleistothecia and conidiophores, spathulate vesicles
and rather ellipsoidal conidia. The second species is characterized by its unique ascospores with two low equatorial crests,
an evident furrow as a deep depression, and finely reticulate convex surfaces. The validation of these new species is supported
further by analyses of the β-tubulin, calmodulin and actin gene sequences. 相似文献

Three new species of Neosartorya and one new Aspergillus of section Fumigati are proposed using a polyphasic approach based on morphology, extrolite production and partial β-tubulin, calmodulin, and
actin gene sequences. The phylogenetic analyses using the three genes clearly show that the taxa grouped separately from the
known species and confirmed the phenotypic differences. Neosartorya denticulata is characterized by its unique denticulate ascospores with a prominent equatorial furrow; N. assulata by well developed flaps on the convex surface of the ascospores which in addition have two distinct equatorial crests and
N. galapagensis by a funiculose colony morphology, short and narrow conidiophores and ascospores with two wide equatorial crests with a microtuberculate
convex surface. Aspergillus turcosus can be distinguished by velvety, gray turquoise colonies and short, loosely columnar conidial heads. The four new taxa also
have unique extrolite profiles, which contain the mycotoxins gliotoxin and viriditoxin in N. denticulate; apolar compounds provisionally named NEPS in N. assulata and gregatins in N. galapagensis. A. turcosus produced kotanins. N.
denticulata sp. nov., N. assulata sp. nov., N. galapagensis sp. nov., and A. turcosus sp. nov. are described and illustrated.

Aspergillus takadae is characterized by its heterothallic reproduction, pale yellow cleistothecia, broadly lenticular ascospores with two short equatorial crests and smooth convex surfaces, and broadly ellipsoidal to ovate conidia with a smooth wall. The validation of these novel species is supported further by the analyses of the β-tubulin, calmodulin, actin, and RPB2 sequences. In addition, the phylogenetic tree and DDBJ accession numbers of all the species of Aspergillus section Fumigati are presented. We report on the crossing of A. takadae species and the result of crossing A. takadae with a closely related species, A. spathulatus. 相似文献

We have studied the effect of a change in the endogenous hormone equilibria on the competence of tomato (Lycopersicon esculentum) cells to defend themselves against the fungal pathogen Fusarium oxysporum f. sp. lycopersici. Calluses from cvs Davis and Red River, respectively resistant and susceptible to Fusarium and transgenic for an auxin- or cytokinin-synthesizing gene from Agrobacterium tumefaciens, were used. The integration of Agrobacterium hormone-related genes into susceptible cv Red River can bring the activation of defense processes to a stable competence as assessed by the inhibition of mycelial growth in dual culture and gem-tube elongation of Fusarium conidia, the determination of callose contents, peroxidase induction and ion leakage in the presence of fusaric acid. This is particularly true when the transformation results in a change of phytohormone equilibria towards an higher cytokin in concentration. On the contrary, in resistant cv Davis the inhibition of both fungal growth in dual culture and conidia germination is higher when the hormone balance is modified in favour of the auxins. No significant effect was observed for ion leakage and peroxidase induction, probably because of a constitutive overproduction of cytokinins in Davis cells. 相似文献

A new genus, Neocarpenteles, the Trichocomaceae (Eurotiales), and a new combination, N. acanthosporum, are proposed to accommodate Hemicarpenteles acanthosporus Udagawa et Takada. The fungus is characterized by sclerotioid, nonostiolate, unilocular stromata in which asci gradually
produce, outward from the center, lenticular ascospores with two equatorial crests and convex surfaces ornamented by triangular
ridges and microtubercles, and an Aspergillus anamorph with uniseriate aspergilla. It has the Q-10 system as the major ubiquinone.

In order to localize the anixiopsin, a lectin of the keratinolytic fungus Anixiopsis stercoraria, the authors used a monospecific antiserum prepared by immunization of rabbits with their own erythrocytes coated in vitro with anixiopsin. In light and scanning electron microscopies, lectinic sites were visualized by means of latex microspheres sensitized with anti-rabbit IgG antibodies. In transmission electron microscopy using the IgG fraction of the rabbit anti-anixiopsin immune sera and protein A-gold, anixiopsin seemed mainly present on the outermost cell wall layer of the ascospores, in a pseudomembraneous structure dense to electrons. Implications of these results on physical and biological properties of the lectin are discussed. 相似文献

Molecular markers for the crown rust resistance genes Pc38, Pc39, and Pc48 in cultivated oat (Avena sativa L.) were identified using near-isogenic lines and bulked segregant analysis. Six markers for Pc48, the closest being 6 cM away, were found in a Pendek-39 × Pendek-48 (Pendek3948) population, but none was found in a Pendek-48 × Pendek-38 (Pendek4838) population. Three markers for Pc39 were found in the Pendek3948 population, one of which cosegregated with the gene. This same marker was found to be 6 cM away from the gene in an OT328 × Dumont (OT328Du) population. Nine markers for Pc38 were found in the Pendek4838 population, eight of which are within 2 cM of the gene. One other marker for Pc38 was found in the OT328Du population; however, comparative mapping suggests that the Pc38 region in OT328Du is in a different location than that in Pendek4838. A number of markers unlinked to the genes under study formed linkage groups in both the Pendek3948 and Pendek4838 populations. Four of these show homology or homoeology to each other and to the Pc39 region in Pendek3948. Two RFLP clones closely linked to Pc38 code for a putative leucine-rich repeat transmembrane protein kinase and a cre3 resistance gene analogue. This study provides information to support molecular breeding in oat, and contributes to ongoing research into genomic regions associated with fungal pathogen resistance. 相似文献
