While Agrobacterium has been coopted for use in the genetic modification of plants, it is also a major pathogen, causing crown gall disease in the nursery, orchard, and vineyard industries. Pathogenicity in Agrobacterium is the result of two components. First is the Ti plasmid, which carries virulence genes and the transferred T-DNA region. The second component is the chromosome of Agrobacterium, which comprises diverse bacterial lineages and multiple species-level groups. The Ti plasmid can be transferred from strain to strain, diversifying the pathogen and complicating efforts to understand its epidemiology. This system provides an opportunity to study transmission of plasmids and their impact on disease persistence and spread. However, the movement of plasmids, and diversity of chromosomal lineages, means that conventional methods of using whole genome SNPs to track outbreaks are not sufficient, and new techniques must be developed. Additionally, Ti plasmids, like Agrobacterium, are genetically diverse and represent multiple plasmid types. Using a framework of 200 sequenced Agrobacterium genomes isolated from around the world, and a previously developed model of Ti plasmid types, we modelled their epidemiology. Key to this study was that we first separately analyzed plasmids and strain. Combining results revealed links between nurseries, potential horizontal transfer of the plasmid between strains within nurseries, global spread of plasmids, and long-term persistence of plasmids in the agricultural system. Agricultural practices have the potential to promote the diversification of pathogens and the emergence of new pathogen lineages.","PeriodicalId":11431,"journal":{"name":"Ecological genetics","volume":"75 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72797689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SE can occur naturally in various plant species and it is widely used for clonal propagation, transformation and regeneration of different crops. This process is regulated by hormone treatment and many proteins, among which WUSCHEL-related homeobox (WOX) transcription factors are believed to play crucial roles. The WOX family is involved in the regulation of a wide range of key developmental programs in different plant organs and tissues. CLE peptides are well-known hormonal regulators of plant development. WOX and CLE genes can be related to each other through feedback regulatory loops. \u0000Our previous studies have shown that MtWOX9-1 stimulates SE in Medicago truncatula [1] and overexpression of the MtWOX9-1 gene increases the expression level of the MtCLE08, MtCLE16, MtCLE18 genes in SE. In this study, we examine the overexpression effect of MtCLE08, 16, and 18 on the expression level of MtWOX9-1 gene and a number of other MtWOX genes, which were shown to change expression in SE according to the transcriptomic data. No significant impact of MtCLE overexpression on any MtWOX gene under study was found. \u0000Our findings could be a helpful point for searching and studying new morphogenetic regulators controlling SE and could have a positive impact on plant biotechnology in improving the transformation and regeneration capacity for other legumes. \u0000The research was supported by grant from the Russian Foundation for Basic Research No. 20-016-00124.","PeriodicalId":11431,"journal":{"name":"Ecological genetics","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81047468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is characterized by hypertension, proteinuria, edema, and multiple organ dysfunction. Up to 8% of pregnancies are complicated by preeclampsia, which is one of the most serious causes of maternal and perinatal mortality [1]. For research of pregnancy disorders and development of therapy for it, a mouse model can be used due of the fact that pregnancy development in mice, especially at early stages, is somewhat similar to human and is well-studied, in particular, in terms of molecular biology [2]. One of the possible options for creating mouse models of preeclampsia is considered to be a mutation in the COMT gene encoding сatechol-O-methyltransferase [3]. This enzyme plays an important role in the catecholamines conversion and it also catalyzes the O-methylation of hydroxyestradiol producing methoxyestradiol. COMT gene knockout results in a phenotype similar to preeclampsia with elevated blood pressure and proteinuria [3]. The previous model was obtained through classic transgenesis methods with Neomycin cassette insertion in the COMT locus potentially influencing the results of the experiments. The development of the genome editing systems and its active utilization at Saint Petersburg State University made it possible to obtain a COMT-KO mouse line using CRISPR/Cas9 technology which had not been done in Russia before.

To assess amyloidogenic potential of individual proteins a yeast test-system was developed under supervision of Prof. Y.O. Chernoff. The system is based on usage of genetically modified S. cerevisiae cells auxotrophic for certain growth factors, allowing effective phenotypic selection to search for amyloidogenic proteins within proteomes of various organisms [1].

The proteins that have shown amyloidogenic potential in yeast-based model are being currently tested in vitro and in vivo. Some mutant Escherichia coli strains can be applied for studying propensity of heterologous proteins to form amyloids in vitro.

Aggregation of Sup35 (induction of [PSI+] prion) decreases its functional activity and leads to the suppression of nonsense-mutation as stop-codons become recognized as meaningful more frequently. This phenomenon is the basis of phenotypic detection of Sup35 aggregation in yeast strains possessing nonsense mutation ade1-14 in ADE1 gene. \u0000Yeast is convenient model for genetic, biochemical and molecular biology studies.

At the moment, it is known that over 7% of dicotyledonous plant species are naturally transgenic, i.e. nGMO [1]. These plants contain the genes of agrobacteria, which are integrated in the nuclear genome during infection. In some species of naturally transgenic plants, agrobacterial genes have been preserved for millions of years of evolution. Among these genes, genes encoding octopine/vitopine synthase (ocs/vis) can be distinguished [2]. \u0000The study of homologues of octopin/vitopin synthase genes in naturally transgenic plants: their structures and diversity, products of encoded enzymes will allow us to establish the functions and evolutionary role of homologues in nGMO. Currently, bioinformatic and genetic engineering methods are used to solve these problems. \u0000ocsvis-like were found in 7 species: Albizia julibrissin Durazz., Cenostigma pyramidale (Tul.)

Three clusters contain nGMOs and agrobacteria, showing the relationship of the T-DNA sequences of nGMO with those of currently known strains of of Agrobacterium/Rhizobium. Three clusters contain only nGMOs. One of them consists of species that belong to the Cannabaceae family. Other clusters are heterogeneous.

T-DNA of soil bacteria Agrobacterium integrated into plants genome is called cellular T-DNA (cT-DNA) [1]. Today, more than 50 species of naturally transgenic plants, or natural GMO (nGMO) are known [2, 3]. The function of cT-DNA in plants remains unknown. It is assumed that the fixation of transgenes could give plants different selective advantages depending on which genes had been integrated into the plant [4]. In order to clarify this issue, it is necessary to study more naturally transgenic plants. Until recently, the list of nGM plants contained less than 2 dozen species, but a search through genomic and transriptomic sequencing data made it possible to more than double this list [2]. In this work, we used the same approach, looking for cT-DNA genes in whole genome sequencing data that have appeared in the NCBI WGS since 2021. We found 14 new species of naturally transgenic plants, among which the most extended cT-DNAs were found in Triadica sebifera, Lonicera japonica, and Lonicera maackii. The cT-DNAs in these species are organized as imperfect inverted repeats. In the genomes of the species Paulownia fortunei, Apocynum venetum, Elaeagnus angustifolia, Erythroxylum havanense, E. densum, E. daphnites, E. cataractarum, Ceriops decandra, Camellia oleifera, Silene uniflora, short cT-DNAs containing only opine synthesis genes were found. We also estimated the approximate age of the cT-DNAs. The first described examples date back to the Late Paleogene, and the process continues to the present.

However, most countries lack national strategy providing science-based substantiated procedure of creating, distribution and safe production of GMP. Rapid development of agricultural biotechnology and GMP production offered many economical benefits but also caused concern due to their potential environmental impact. To date, truly negative effects of GMP production, revealed in the course of growing, are known: harmful effect of entomocide Cry-proteins (Bt endotoxins) on non-target biota, target phytophage resistance to insecticidal plants, phytophage species succession to replace the species eliminated in the agrocoenosis. Vertical transfer of GMP transgenes (repollination between transgenic plants and wild species or isogenic varieties), as well as slow decomposition of transgenic plants remains all these factors can have remote environmental consequences [2, 3]. Wind-dispersed pollen of insecticidal GMP contaminates soil and open water reservoirs by toxins, thus posing potential hazards for aquatic organisms and geobionts (including rhizospheric organisms). \u0000Thus, uncontrolled GMP production and introduction, creates a real threat of losing biodiversity and genetic diversity of indigenous plants due to biological contamination. Therefore, GMP cultivation and monitoring in the fields is of exceptional importance and must be regulated by a science-based national strategy. This strategy would allow to exclude agroecological and environmental genetic risks, to keep the genetic diversity of natural plant communities.","PeriodicalId":11431,"journal":{"name":"Ecological genetics","volume":"93 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72849198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
