Non-brittle rachis 1 (Btr1) gene involves in regulation of the brittle/ non-brittle spike trait, which is one of the key domestication traits in Triticum species. In this study genetic variability of Btr1 genes from di- and tetraploid wheat species and Aegilops speltoides, which is donor of B-genome for polyploid wheat species, were investigated.

In the present study, the components of the gene regulatory network governing the anthocyanin and proanthocyanidin biosynthesis in barely grain and leaf sheath were identified based on comparative mapping and transcription analysis approaches. The regulatory relationships between the genes were established using unique barley anthocyanin/proanthocyanidin mutants and near-isogenic lines.

New scientific program of genomic screening of the Nikita Botanical Gardens plant collections targeted at comprehensive description of their molecular diversity in close connection with morphological, physiological and others phenotype features has started. Strategic goal is to develop and implement advanced molecular approaches for plant biotechnology, breeding, propagation, and conservation routine works. Two whole-genome sequencing projects to produce a high quality assembly of the reference genomes of the common fig Ficus carica L. (Moraceae) and Crimean endemic species Heracleum ligusticifolium M. Bieb. (Apiaceae) are in progress. Several hybrid assembly approaches using combined data sets with long and short reads obtained by Oxford Nanopore MinION and Illumina NextSeq550 instruments are tested to create accurate and well-resolved reference genome. The first versions of the reference genomes of F. carica cultivar ‘Sabrutsiya Rozovaya’ and H. ligusticifolium were made, and their annotations are performing. Subsequent improvement and development of the primary genome assemblies up to \”pan-genome\” rank will be carried out using advanced bioinformation approaches and computational tools by assimilation of new sequenced genomes and transcriptomes of the model species taken from the NBS-NSC collections and from nature biotopes as well. Such integrative reference genome construction will provide an important resource both for advanced molecular breeding and fundamental researches in plant biology and ecology based on genomic approaches using F. carica and H. ligusticifolium as model species.

Legumes (Leguminosae, syn. Fabaceae) develop two highly integrated mutually beneficial endosymbioses, namely nitrogen-fixing root nodules with rhizobia bacteria and arbuscular mycorrhiza that makes them a key component of modern technologies for crop production. We applied the comparative transcriptome analysis for identification of pea genes essential for effective symbiosis with beneficial soil microbes. The allelic forms of the two identified genes most likely have a significant effect on the effectiveness of symbiosis pea with rhizobia bacteria and arbuscular mycorrhiza.

Rust diseases of cereals are caused by pathogenic fungi and can significantly reduce plant productivity. Many cultures are subject to them. The disease is difficult to control on a large scale, so one of the most relevant approaches is crop monitoring, which helps to identify the disease at an early stage and make efforts to prevent its spread. One of the most effective methods of control is the identification of the disease from digital images that obtained by a smartphone camera. In this paper, we present a deep learning algorithm that uses a digital image of wheat plants to determine whether they are affected by a disease and, if so, what type: leaf rust or stem rust. The algorithm based on the convolution neural network of the densenet architecture. The resulting model demonstrates high accuracy of classification: the measure of accuracy F1 on the validation sample is 0.9, the AUC averaged over 3 classes is 0.98.

Grains morphometry is an important step in selecting new high-yielding plants. The manual assessment of parameters such as the number of grains per ear and their size is laborious. The solution to this problem is image-based analysis, which can be performed using a desktop PC. The effectiveness of this analysis in the field can be improved through the use of mobile devices. We propose a method for the automated evaluation of phenotypic parameters of grains using mobile devices running the Android operational system. The experimental results show that this approach is efficient and sufficiently accurate for the large-scale analysis of phenotypic characteristics in wheat grains.

Flax is grown for seeds in many countries. Depending on the ratio of fatty acids, seeds are used in pharmaceutical, food, feed, or polymer production. It is known that genes of FAD3 family responsible for the desaturation of linoleic (LIO) into linolenic (LIN) fatty acid and some alleles of these genes are associated with a certain composition of flax oil. However, the development of the marker-assisted selection of flax is complicated due to a lack of methods for the identification of these polymorphisms. In the present study, we used 84 flax cultivars/lines with diverse content of LIO and LIN to search for fatty acid associated SNPs and then developed HRM-based system for identification of these SNPs that can increase the efficiency of breeding by obtaining pure improved cultivars with the targeted LIO and LIN content.

Organelle genomes are an important tool to investigate domestication, distribution and microevolution of plant species. However, they have found limited use in cereal intraspecific studies so far.

In the present study, organelle genomes of wild (Hordeum vulgare subsp. spontaneum) and cultivated (H. vulgare subsp. vulgare) barley forms were sequenced. We conducted theВ NGS of isolated chloroplast and mitochondrial DNA mixtures. This non-trivial approach allowed to obtain both genomes for each sample but required some specific steps in the data processing.

Comparative analysis of obtained sequences revealed more than 100 polymorphic sites in the chloroplast genome, including new intraspecific SSR-markers, and more than 20 polymorphisms in the mitochondrial genome.

We also carry out the phylogenetic analysis of these genomes. Chloroplast and mitochondrial DNA trees were consistent with each other, indicating the presence of two large clades containing both wild and cultivated forms.

Our results are conforming with a hypothesis of several domestication centres of barley. They also provide direct evidence of a higher rate of nucleotide substitutions in the chloroplast genomes as compared to that of mitochondria on a microevolution scale. The revealed high level of variability of chloroplast genomes makes it possible to use them for intraspecific barley differentiation.
