The complete nucleotide sequence of Juglans regia chloroplast genome (cpDNA) was carried out using Illumina Hiseq 2500. The genome is 160 537 bp in length, and the overall base composition of H-strand is 31.59% for A, 18.35% for C, 17.76% for G and 32.30% for T. Similar to the other higher plants, cpDNA have a large single copy (LSC) region of 90 059 bp and(More)
The complete nucleotide sequence of Pinus tabuliformis chloroplast genome (cpDNA) was carried out using Illumina Hiseq 2500. The genome is 119 646 bp in length, and the overall base composition of H-strand is 30.6% for A, 19.3% for C, 19.2% for G and 30.9% for T. There are 116 genes in the cpDNA, including 74 protein-coding genes, four ribosomal RNA genes(More)
By using ITS - nrDNA-RELP, ITS sequencing, and RAPD molecular marker, this paper studied the genetic diversity of 11 isolates in 5 races of Melampsora larici-populina from different regions. The results indicated that the genetic differentiation of M. larici-populina was correlated to its geographical distribution, which could be grouped into northern and(More)
The obligate biotrophic fungus Melampsora larici-populina (Mlp) causes devastating poplar foliar rust disease. In pathogens, the Hog1-type mitogen-activated protein kinase (MAPK) gene is involved in both pathogenesis and the response to various stresses, including osmotic stress. However, there are few reports on its role in M. larici-populina. In the(More)
The effects of extraction fluids from the leaf litter from different dominant tree species on the functional characteristics of the soil microbial community were studied to understand how changes in soil quality and synergism between plants and soil contribute to the process of forest succession. Leaf litter from dominant tree species at different stages of(More)
A post-fire morel collected from Populus simonii stands in Mt. Qingling was identified as Morchella crassipes Mes-20 by using nuclear ribosomal DNA internal transcribed spacer phylogeny. It was inoculated into sweet corn to observe colonized roots in purified culture and in greenhouse experiments. The elongation and maturation zones of sweet corn were(More)
Cankered, dying seedlings of Juglans regia were observed in Shaanxi province in the northwest region of China. Neofusicoccum parvum was isolated from these cankered tissues, with the identification based on morphology and an ITS-nrDNA sequence. In order to demonstrate how cultures of N. parvum could cause the expected symptoms, artificial infection, using(More)
