- Abstracts are provided in electronic form, no more than 2 pages of text in Microsoft Word format (docx, doc).
- The font used is Times New Roman,
- font size 12 pt,
- line spacing single,
- sheet format is A4 with margins: left – 3 cm, right – 2 cm, top and bottom – 2 cm, paragraph – 1.25 cm.
- commas, not periods, are used to separate the integer and fractional parts of numbers (GOST 15.101).
- The text of the abstract may contain no more than 1 table or figure (color/black and white).
- Source of funding (if any).
2. The text is formatted in accordance with the following requirements:
Text structure:
TITLE OF THE WORK
(bold font, capital letters, centered);
/Skip line/
Initials and last name of authors
with superscripts, at the place of work
(bold font, lowercase letters, centered);
/Skip line/
Full name of the organization (indicate the abbreviation in brackets), postal address, contact e-mail
(italic, bold, lowercase, centered);
/Skip line/
The text of the abstract, including the introduction, materials and methods, results and conclusions
(justified, normal font)
3. Design of a figure or table.
One small table or one figure (integrated into the Word file) is acceptable. Figures are accepted in both black and white and color and are not editable, so please provide them in high resolution. References to figures or tables must be included in the text before the figure/table itself; the full title is Figure 1 or Table 1.
The caption is formatted as follows:
Figure 1. Figure Title
Table titles are formatted as follows:
Table 1 – Table Title
4. Formatting the list of references
In the text, references to sources are numbered in square brackets in the order they are cited.
List of references
The order of the list is by reference in the text.
Before the source number, there is a paragraph indent (1.25 cm).
After the source number, there is a period.
Examples of various formatting sources are available in GOST R 7.0.100-2018 (Appendix E). Please note:
No spaces are allowed between the author’s initials.
Two slashes (//) are used between the article title and the journal title, with no spaces or periods.
To separate parts of a bibliographic entry, use a hyphen (-), not an en dash (–) or an em dash (—).
For journal numbers, use N for Russian-language sources and No for foreign sources, not №.
Between page numbers, use a hyphen with spaces: not P. 12-13. and not P. 12 – 13., but P. 12 – 13.
5. An example of abstract formatting is given below.

The growing demand for high-quality food products is driving the development of bio-based farming methods, which utilize microorganisms, including endophytes, to stimulate plant growth. Plant-associated microbiomes play a critical role in plant health, nutrition, growth, and adaptation. However, studies on the composition of endosphere microbiomes are limited.
The study presents an analysis of the bacterial endophytic microbiome of lettuce seeds (Lactuca sativa L., cv. Ozornik) using high-throughput sequencing of 16S rRNA amplicons.In this study, the taxonomic composition and putative functional properties of endophytic bacteria in seeds were assessed. Furthermore, the pathways of lettuce (Lactuca sativa) endosphere microbiome formation through vertical (seeds) and horizontal (substrate) transfer were explored under hydroponic and soil conditions.
The bacterial endophytic community of lettuce seeds exhibited low diversity (Shannon index ranged from 1.1 to 1.84, Simpson index from 0.57 to 0.83). The dominant phyla were Pseudomonadata (83%), Actinomycetota (14%), and Bacillota (3%). The following genera were identified in the microbiome: Pantoea (32%), Rhodococcus (13%), Candidatus Profftella (13%), Janthinobacterium (7%), Pseudomonas (9%), Enterococcus (3%) and Alcaligenes (2%), which have a wide range of beneficial properties: stimulation of plant growth, suppression of phytopathogens, increased stress resistance, participation in the biodegradation of pollutants and detoxification of heavy metals. The structure and functional potential of the microbiome varied between samples, possibly due to differences in the starting material and growing conditions. The seed microbiome contained 236 OTUs, the rhizosphere soil contained 1,594 OTUs, and the hydroponic solution contained 448 OTUs. The root endosphere of lettuce grown in soil contained 295 OTUs compared to 177 in hydroponics, while the leaf microbiome contained 43 OTUs in soil and 115 OTUs in hydroponics. Overall, 30–51% of the leaf and root microbiomes originated from the seed microbiome, while 53–65% of the root microbiome originated from the substrate (figure 1).
Figure 1. Contribution of various sources to the formation of the endosphere microbiome of plants in soil conditions.
An overlap between the rhizosphere soil microbiome and the root microbiome was found. The results obtained expand our understanding of the composition and functions of endophytic bacteria in lettuce seeds, which is important for the development of new biological control agents for plants consumed by humans in unprocessed form. This study opens new avenues for understanding the lettuce seed microbiome and the pathways that shape the endospheric microbiome of adult plants. These results lay the foundation for future research aimed at better understanding the dynamics of the leaf microbiome and plant defense.
The work is carried out in accordance with the Strategic Academic Leadership Program “Priority 2030” of the Kazan Federal University of the Government of the Russian Federation.
