近年甘肃省河西走廊一带胡萝卜上发生一种叶斑病,严重时造成减产20%~30%。其病原物为丝分孢子真菌(半知菌)腔孢纲Coelomycetes中一未描述的真菌。该菌具有分生孢子器,但其形态与相似属茎点霉属Phoma、鞘茎点霉属Coleophoma和拟腊肠茎点霉属Allantophomopsis不同,遂建立类腊肠茎点霉属Allantophomoides(新属);其模式种为胡萝卜类腊肠茎点霉Allantophomoidescarotae(新种)。研究的标本保存在山东农业大学植物病理学标本室(HSAUP)。 相似文献

Heterodera carotae, the carrot cyst nematode, is a significant pest affecting carrot globally. Here we present the draft genome of H. carotae, which was generated from short read libraries from Illumina HiSeq technology, and the corresponding genome annotation. 相似文献

Molecular Characterization of Cyst Nematode Species (Heterodera spp.) from the Mediterranean Basin using RFLPs and Sequences of ITS-rDNA 总被引:2,自引:0,他引:2

Fifteen populations of cyst‐forming nematodes belonging to 11 known and one unidentified species collected in countries bordering the Mediterranean Sea were studied using polymerase chain reaction restriction fragment length polymorphism (PCR–RFLP) and internal transcribed spacer (ITS)‐rDNA sequences. RFLP profiles generated by the restriction enzymes AluI, AvaI, Bsh1236I, HaeIII, Hin6I, MvaI, PstI and RsaI are presented for Heterodera carotae, H. ciceri, H. fici, H. filipjevi, H. goettingiana, H. hordecalis, H. humuli, H. mediterranea, H. ripae and H. schachtii. Molecular data support the first detection of H. filipjevi from wheat in Italy and H. ripae from nettle in Greece. A relative high level of sequence divergence between populations of H. hordecalis was observed. This suggests that two species might presently be grouped under this taxon. The phylogenetic relationship between the Mediterranean cyst‐forming nematode species is analysed based on the ITS‐rDNA sequences. 相似文献
