The duplication and differentiation of opsin genes are the main mechanisms for the production of new light pigment sensitivity. Throughout the evolution of animals, many instances of opsin gene duplication and loss have occurred, forming the sensitivity of the various animal visual systems we observe today. In recent years, extensive and in-depth research has been carried out on visual proteins. This article describes the types of photoreceptors, the color vision system of insects, the classification of visual proteins, the phenomenon of co-expression of visual proteins, the duplication and deletion of visual protein genes, and the mechanism and research status of the physiological functions of visual proteins.

Native to China, Republic of Korea, DPR Korea and Japan, it has been accidentally introduced into the United States, Canada, Switzerland, Liechtenstein, Germany, France, Italy, Hungary and Greece since the mid-1990s. With its rapid expansion, this insect is possibly becoming a serious agricultural pest worldwide. In the newly invaded areas, little nature enemy is found to control this pest efficiently. For example, indigenous parasites Telenomus podisi and Trissolcus flavipes in Canada and Switzerland respectively can attack H. halys eggs, but neither wasp can complete development successfully. As chemical pesticides would cause social and ecological side effects, classical biological control is consider a promising management approach, which leading to permanent establishment and long-term control H. halys in invaded areas by introducing a co-evolved host specific biological control agent. In this paper, we reviewed taxonomy, distribution, damage, biology, ecology and biological control of H. halys, with particular focus on nature enemies in the area of origin.

It has a good potential in biocontrol application. In the study, the inhibitory effects of strain Ba-0321 sterile filtrate on Fusarium oxysporum and Phytophthora nicotianae were determined by methods of co-culture. The whole genome of strain Ba-0321 was sequenced using the second-generation Illumina and the third-generation Nanopore platform, then analyzed for genome assembly, gene functional annotation, prediction of secondary metabolite synthetic gene clusters. The results showed that the sterile filtrate of strain Ba-0321 has inhibitory effects on both F. oxysporum and P. nicotianae. The culture medium containing 10% sterile filtrate has a higher inhibitory rate on the mycelial growth of the two pathogens, reaching 57.38% and 34.30%, respectively. The results of whole genome sequencing showed that the genome size of strain Ba-0321 was 4099109 bp, including 3897 coding genes, and the sequencing data are available in the GenBank database (accession No. CP101904). There were a large number of genes encoding enzymes, terpene, polyketone metabolic pathways, and genes involved in defense mechanisms have been annotated in the GO, COG and KEGG databases. Using anti-SMASH software, 13 secondary metabolite synthesis gene clusters were predicted encoding antibacterial substances such as Surfactin、Fengycin、difficidin、Bacillaene、Bacillibactin、Macrolactin H、Bacilysin. The existence of biosynthetic gene cluster for antibacterial substances and defence machainsm related genes in Ba-0321 strain genome were verified by PCR amplification and sequencing. The enzyme activity test results showed that the strain has resistant enzyme activities such as protease, chitinase, and cellulase.. This study provides a basis for analyzing the antimicrobial mechanism of strain Ba-0321 and mining antifungal related gene resources at the genomic level, which is of a great significance for research and application of the Ba-0321 strain in future.

Members of PSB are regarded as important components in microbiome from plant surface and soil. Attributed to their extraordinary metabolism versatility, photosynthetic bacteria often play significant roles in processes like plant nutrient uptake, growth and development, as well as stress resistance and establish close relationships with plants and other microorganisms in agroecosystem. This confers PSB a reputation as plant beneficial microorganism. In this article, we mainly focus on the PSB-produced effects on the plant nutrition, growth promotion, stress resistance and disease management. The biological activities carried out by PSB, e.g., nitrogen fixation, phosphate solubilization, heavy metal immobilization, phytohormone and plant growth regulator production, antimicrobial compound synthesis, plant systemic resistance induction, are illustrated. Those activities are recognized as the main resorts to maintain the plant and soil health. In conclusion, as a group of microbes with properties including metabolism versatility, wide distribution, flexibly adaptive to environment, and intimately interactive with plants, photosynthetic bacteria can be exploited as a valuable resource for development of novel multi-functional bio-fertilizer and bio-control agent.

Research and Application on Namaticidal Plants and Phytochemicals WANG Jia, ZENG Guangzhi, WANG Zhe, TAN Ninghua journal1    2018, 34 (3): 469-479.   DOI: 10.16409/j.cnki.2095-039x.2018.03.017 Abstract （407）      PDF（pc） （1267KB）（3054）       Knowledge map    Save Plant-parasitic nematodes, the second destructive pathogens in agriculture, could not only attack their host using various strategies and induce profound changes in plants, but also cause secondary diseases following tissue damage, which always heavily influence the growth and productivity of crops. So it is extremely urgent to find effective nematicides. There are four main methods for nematode control:agricultural control, physical control, chemical control and biological control. Among them, biological control is a new method for plant-parasitic nematode control using animals, plants, microorganisms and their secondary metabolites. As one kind of secondary metabolites, phytochemicals are the core of botanical pesticides. Comparing to synthetic nematicides, plant-derived nematicides are more kindly to environment, more toxic to target organisms, less toxic to nontarget organisms and unlikely to generate nematode resistance. Therefore it is significant to develop new green nematicides using nematicidal chemicals isolated from plants. Herein, nematicidal plants from Asteraceae, Leguminosae and Labiatae, nematicidal phytochemicals including alkaloids, terpenes, isothiocyanates, glucosinolates and phenolics, their action mechanisms against pests and the applications of plant-origin nematicides were reviewed. Plant-derived nematicides are not only helpful to the control of plant-parasitic nematodes, but are also friendly to the environment and human. We hope that more researchers could pay attention on the research of nematicidal plants, their secondary metabolites and their nematicidal mechanism which will contribute to the control of plant-parastic nematodes and the finding of more lead compounds for nematicides.
