Bioinformatic search of actin genes in the genomes of Triticum aestivum, Hordeum vulgare and Brassica rapa was performed. It was found that exon regions of actin genes in the studied plant species are highly conserved, while intron regions are hypervariable, which may be useful for the development of DNA markers based on the assessment of intron polymorphism. Design and synthesis of degenerate universal primers was carried out to evaluate the actin gene intron length polymorphism in higher plants. Testing of the developed DNA marker system, which reveals the polymorphism of the intron length of actin genes, was carried out on samples of monocotyledonous and dicotyledonous plants of different taxonomic groups. A DNA marker system evaluating the intron length polymorphism of actin genes allowed genotyping and differentiation of Ae populations qualitatively. Biuncialis in the Crimea, revealing a significant number of polymorphic amplicons of introns of actin genes. High heterogeneity and genetic heterogeneity of the investigated natural populations of Egilopsis have been shown. The analysis of the polymorphism of the length of the introns of the actin genes in the Antarctic species Deschampsia antarctica was carried out. Genetic monomorphism for this type of DNA marker has been established. Genotyping and differentiation of barley (Hordeum vulgare L.), tomato (S. lycopersicum), potato (S. tuberosum) and flax varieties of Ukrainian and Belarusian breeding were also conducted. In general, species-specific DNA profiles with a specific set of fragments of introns of actin genes for all analyzed plant species were obtained. On the whole, DNA markers evaluating the intramine length polymorphism of actin genes made it possible to qualitatively genotype plant species and varieties

Saving a scientific data set occurs in two stages:
1.) Creating a data set
Enter the name of the set, a brief description of the set (annotation), and click the “Create set” button. After that, a draft data set will be automatically created, which you can save for further work with the set. The system will redirect you to the “Data set information” page.
2.) Filling in the data
On the “Data set information” page, you need to fill in all the fields related to the data set and upload the files.
Please note! Each file is uploaded separately. This is done to ensure the stable operation of the system.
Once you have filled in the information about the scientific data set and added the necessary files, you can save the draft or send the data to the system.
Please note! Once the data has been sent, you cannot change it.
Drafts are necessary for storing the data set and editing it before sending.
All accounts on the NRA website go through a standard registration procedure and are verified. However, in order to obtain additional features, such as publishing open reviews of academic texts, verification by affiliation is required.
To obtain the status “verified”, you must change your primary email address to a corporate one, which is tied to a scientific or educational institution.
For example: user@ukrintei.ua, user@nas.gov.ua
After confirming your corporate email address, your account will be automatically verified by affiliation.
If your email address is corporate, but your account does not have a verification mark, you need to write to us at the email address NRAT@ukrintei.ua. After verification, we will add your address to the database, and your account will be verified.
After completing the verification procedure for affiliation, you can change the primary email address to a convenient one for you, without losing your status during the current verification.
You only need to verify for affiliation once.
* We use corporate addresses from the Unified State Database on Education and the State Register of Scientific Institutions Supported by the State
To search for news published on the official website of NRАT in the “News” section, you need to enter one word, several words, or an exact phrase in the search field. Different terms are separated by spaces.
The search is performed everywhere – in the title and the news text.
For a more comprehensive result, it is recommended to use word stems (parts of words without endings).
When using multiple words for the search, they are combined using one of the logical methods described below.
By default, the logical connector “and” is used. In this case, search results will include all news releases that contain the specified words, even if they are located separately from each other and are in different parts of the text.
Example: Search phrase: OECD report. Search result: all news containing the words “report” and “OECD” in the text and in the title, both together and separately.
If a phrase or phrase is enclosed in quotation marks (“), the results will include all publications where this exact phrase or phrase is found.
Example: Search phrase: “OECD report.” Search result: all news containing the exact phrase “OECD report.”
If you know the publication date of the news or are interested in a specific time frame in which they were published on the website, you can select such a date or date range in the additional field that looks like a calendar. The date is entered in the format year-month-day and confirmed by clicking on the corresponding date in the calendar dropdown. You can enter a date or choose one by browsing through the calendar by months and years. By default, the interval starts from the oldest date (2018-01-23) and ends with the current date.
You can also use one or more hashtags, which are located under the search field on the right side of the “News” page.
Please note: The search for academic texts is carried out in a separate search window at the following link https://nrat.ukrintei.ua/searchdb.
