“…This leads to the limited synthesis of GAs in the roots and to the decrease in their transfer to the above-ground part of the plant. That is the way the dwarf trees are formed (Liu et al, 2017). After applying exogenous GA3 to the apical parts of the shoots of dwarf form M. baccata, was observed a significant increase in the processes of growth of these shoots compared to those of the shoots without application of GA3 (Stolbikova et al, 2018).…”

Peculiarities of hormonal status of dwarf and winter hardy trees of Siberian crabapple (Malus baccata L. Borkh.) were studied. The research was carried out on plants growing in the natural habitat (western Transbaikalia, 2009(western Transbaikalia, -2010 and in a cultivated orchard (Irkutsk city, 2012(Irkutsk city, -2013. The study showed that dwarfism is caused by a decline in indole-acetic acid (IAA) content and by the associated changes in the IAA:ABA (abscisic acid) content ratio in the crabapple plants in both growing conditions. During the experimental period, this ratio was above and below unity for tall and dwarf trees, respectively. The content of phytohormones remained unchanged in the studied forms in the cultivated orchard despite the increase in the growth rate of scions. It was concluded that the IAA content depended on the synthesis of the acid in the above-ground part of plants. In this context, the contribution of phytohormones to the formation of the dwarfism of M. baccata was discussed. We believe that the combination of winter hardiness and dwarfism in these trees make them very promising as parental forms for breeding resistant rootstocks.Please use the following format when citing the article: Rudikovskii A.

“…Citrus is very important worldwide for fruit production. Results of RNA-Seq data analysis in Citrus species showed that expression levels of ARF1, ARF8, GH3 and IAA4 genes were negatively correlated with the growth rate and the content of IAA hormone (Liu et al 2017b), indicating that expression of genes involved in auxin signal transduction may regulate the hormone levels. RNA-Seq data analysis between blight and healthy root samples identified mechanisms associated with blight phenotypes, starch accumulation, and abiotic stress (Zhang et al 2016).…”

RNA-seq and single-cell genomic research emerge as an important research area in the recent years due to its ability to examine genetic information of any number of single cells in all living organisms. The knowledge gained from RNA-seq and single-cell genomic research will have a great impact in many aspects of plant biology. In this review, we summary and discuss the biological significance of RNA-seq and single-cell genomic research in plants including the single-cell DNA-sequencing, RNA-seq and single-cell RNA sequencing in woody plants, methods of RNA-seq and single-cell RNA-sequencing, single-cell RNA-sequencing for studying plant development, and single-cell RNA-sequencing for elucidating cell type composition. We will focus on RNA-seq and single-cell RNA sequencing in woody plants, understanding of plant development through single-cell RNAsequencing, and elucidation of cell type composition via single-cell RNA-sequencing. Information presented in this review will be helpful to increase our understanding of plant genomic research in a way with the power of plant single-cell RNA-sequencing analysis.

“…Transcriptional profiling of the scions of Malus domestica revealed that differences in the expression of 116 transcripts were correlated with rootstock regulation of tree size in the scion [12]. In citrus, most differentially expressed genes (DEGs) of 'Shatangju' mandarin (Citrus reticulata Blanco) leaves were involved in the auxin signal transduction pathway and gibberellin (GA) biosynthesis pathway in grafted plants [13]. The whole-leaf transcriptome of a grapevine grafted onto five selected rootstocks showed high variability in gene expression, and 2692 DEGs and metabolites were involved primarily in defense responses (Chitarra [14].…”

The tree size of the 'Shatangju' mandarin scion was found to be largest when grafted onto Canton lemon, and more than 1000 DEGs were found to be involved in the oxidoreductase function, hormonal signal transduction, and the glycolytic pathway in red tangerine vs. Canton lemon [13]. However, molecular regulation of the grafting effect on stem secondary growth has seldom been studied.…”

Grafted plant is a chimeric organism formed by the connection of scion and rootstock through stems, so stem growth and development become one of the important factors to affect grafted plant state. However, information regarding the molecular responses of stems secondary growth after grafting is limited. A grafted Rosa plant, with R. rugosa ‘Rosea’ as the scion (Rr_scion) grafted onto R. multiflora ‘Innermis’ as the stock (Rm_stock), has been shown to significantly improve stem thickness. To elucidate the molecular mechanisms of stem secondary growth in grafted plant, a genome-wide transcription analysis was performed using an RNA sequence (RNA-seq) method between the scion and rootstock. Comparing ungrafted R. rugosa ‘Rosea’ (Rr) and R. multiflora ‘Innermis’ (Rm) plants, there were much more differentially expressed genes (DEGs) identified in Rr_scion (6887) than Rm_stock (229). Functional annotations revealed that DEGs in Rr_scion are involved in two Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways: the phenylpropanoid biosynthesis metabolism and plant hormone signal transduction, whereas DEGs in Rm_stock were associated with starch and sucrose metabolism pathway. Moreover, different kinds of signal transduction-related DEGs, e.g., receptor-like serine/threonine protein kinases (RLKs), transcription factor (TF), and transporters, were identified and could affect the stem secondary growth of both the scion and rootstock. This work provided new information regarding the underlying molecular mechanism between scion and rootstock after grafting.
