: Eucalypt is the vernacular name used to refer to trees of the three genera, Angophora Cav. , Corymbia K. D. Hill & L.A.S. Johnson and Eucalyptus L ‟ Herit. These closely related genera are within the Myrtaceae family and include around 1000 taxa in total, nearly all of which are indigenous to Australia. In China, over 5 million ha of industrial plantations have been established with selected eucalypt taxa. However, there are no plantations in this country managed
The new member of the subterranean family Niphargidae (Crustacea: Amphipoda: Senticaudata) is discovered and described from the Maronia Cave, near Maronia town, Rhodopi district, NE Greece, Niphargus beroni, spec.nov., and its relation to some other members of genus Niphargus from adjacent regions of Balkan is discussed.
The SNP markers of Megalobrama amblycephala, Ancherythroculter nigrocauda and Bo Fang “Xianfeng No. 2” were developed by SLAF-seq in this study. Further analysis on genetic diversity and genetic population were also done in this paper. The results showed that the efficiency of Enzyme digestion was 90.11% and 181.13M reads were obtained from three fishes. 1,339,007 SLAF labels and 446,680 SNP markers were through bioinformatics analysis. And the Q30 of mean sequencing was 93.03%, the mean GC content was 37.79%. The results showed that the observed allele number (No) was 2.0, and the expected allele number (Ne) was 1.63. The observed heterozygosity (Ho) was 0.08, while the expected heterozygosity (He) was 0.36. The genetic diversity index was 0.41, the Shnnon Wiener index was 0.54, and the PIC was 0.29, the MAF was 0.28. These results suggest that the genetic diversity of three populations were in the medium level. It might be related to artificial selection. The nearest genetic distance was between Bo Fang “Xianfeng No. 2” and Megalobrama amblycephala, and the furthest distance between was Megalobrama amblycephala and Ancherythroculter nigrocauda, which were in accordance with their shapes.
The Chinese herbal medicine industry in Dazhou has a long history of breeding, obvious variety advantages, and the industry has begun to take shape, but there are also problems such as weak macro guidance from the government, non-standard planting and production, lack of brand awareness, and insufficient integration of the industrial chain. In response to the above problems, it is suggested to strengthen government guidance and technical services, promote large-scale and standardized breeding, establish an Internet + information service platform, highlight characteristics, build brands, integrate the Chinese herbal medicine industry with the construction of beautiful villages, integrate resources to carry out circular economy model research and other measures, so as to provide references for the development of Chinese herbal medicine industry in Dazhou.
