“…The genetic background of ginkgo resistance to a wide spectrum of biotic and abiotic stress conditions was also analysed (Mohanta, 2012). In vitro approaches of ginkgo micropropagation are known from the literature (Tommasi and Scaramuzzi, 2004;Mantovani et al, 2013).…”

Ginkgo biloba L. is the oldest species of tree on our planet. It is a dioecious species characterized by exceptional resistance to climate change and natural influences, which predetermines it as a suitable species for urban planting. Not to be overlooked is the ginkgo benefit in terms of the medical effects of leaf metabolites. Due to its aesthetic value ginkgo is becoming popular in family gardens. The aim of our research was the evidence and description of ginkgo trees in Slovakia. The study presents the completion of data on the cultural distribution of this tree. We confirmed the occurrence on more than one hundred localities (103 localities). Some previously registered localities (18) were not found, or trees were felled for various reasons (5). We evaluated the basic dendrometric and growth parameters of the oldest ginkgo trees (aged 242 -111 years), found in 35 localities of Slovakia. The presented research results bring several new information concerning the tree gender determination, tree habitus, phenological rhythm of development and others. Morphologically interesting solitary trees, including trees with shoots known as lignotubers or "basal chichi" (locality Hajná Nová Ves), or the occurrence of fruits on the leaves, referred to as cv. Ohatsuki (Lučenec) are described and documented by photos.

“…Over the course of evolution, the earth has undergone enormous changes and the plant kingdom has been subjected to numerous stresses [45][46][47]. All living organisms had to adapt to a changing environment, which resulted in the increased importance of some protein-coding genes while others became less important [48][49][50].…”

Construction of anti-codon table of the plant kingdom and evolution of tRNA selenocysteine (tRNASec)

Background The tRNAs act as a bridge between the coding mRNA and incoming amino acids during protein translation. The anti-codon of tRNA recognizes the codon of the mRNA and deliver the amino acid into the protein translation chain. However, we did not know about the exact abundance of anti-codons in the genome and whether the frequency of abundance remains same across the plant lineage or not. Results Therefore, we analysed the tRNAnome of 128 plant species and reported an anti-codon table of the plant kingdom. We found that CAU anti-codon of tRNAMet has highest (5.039%) whereas GCG anti-codon of tRNAArg has lowest (0.004%) abundance. However, when we compared the anti-codon frequencies according to the tRNA isotypes, we found tRNALeu (7.808%) has highest abundance followed by tRNASer (7.668%) and tRNAGly (7.523%). Similarly, suppressor tRNA (0.036%) has lowest abundance followed by tRNASec (0.066%) and tRNAHis (2.109). The genome of Ipomoea nil, Papaver somniferum, and Zea mays encoded the highest number of anti-codons (isoacceptor) at 59 each whereas the genome of Ostreococcus tauri was found to encode only 18 isoacceptors. The tRNASec genes undergone losses more frequently than duplication and we found that tRNASec showed anti-codon switch during the course of evolution. Conclusion The anti-codon table of the plant tRNA will enable us to understand the synonymous codon usage of the plant kingdom and can be very helpful to understand which codon is preferred over other during the translation.

“…Plants show high resistance to environmental stress, microbial diseases (fungal, viral and bacterial), other pests and gaseous pollutants as ozone and SO 2 , making them suitable for greening the cities. Based on this, G. biloba is considered as a model for studying plant resistance and stress (Mohanta, 2012). Ecological and coenotic stability of G. biloba was observed repeatedly during its cultivation in different geographical regions (Meena, 2015;Stankovic, 2016;Torchik et al, 2018).…”

In recent years, interest in cultivating Ginkgo biloba L. as a medicinal plant has grown in Ukraine, and improvement of the technology of growing this plant in the conditions of the North-East of Ukraine is a relevant problem. The purpose of this article to present research on the morphological structure, growth and viability of young G. biloba plants in grown from seeds by different technologies and comparative analysis of growth and development of G. biloba plants under greenhouse conditions and on open soil. The experiment on G. biloba cultivation was initiated in 2014 in three variants (the plants were grown from the seeds). Variant No 1: G. biloba growing in a greenhouse at 60–80% humidity and temperatures not below +27 ºС; shading (shading level 60%) by green agronetting. Variant No 2: growing in open soil; shading (shading level 60%) by green agronetting; the climatic conditions were typical for Sumy region. Variant No 3: growing in open soil; there was no shading; climatic conditions were typical for the Sumy region. Plant analysis was conducted in June 2018. The following morphometric parameters of G. biloba plants were measured: plant height, annual growth of shoots, number of leaves, leaf size and leaf area, phytomass of the shoots, phytomass of leaves and phytomass of the stem, diameter of the shoots. The sampling used 60 samples. The leaf area was determined by the method of drawing contours on millimeter paper. Statistical processing of research results was carried out by generally accepted modern methods of mathematical statistics using dispersion, correlation, regression and vital analysis. In the conditions of the Ukrainian North East, G. biloba seedlings can be grown successfully in greenhouses and open soil, both with 60% shade by agronetting and without it. Differences between the plants grown in such conditions are insignificant and statistically unreliable. The obtained three to four year old G. biloba seedlings grown using different technologies were 25–30 cm in height and formed 13–17 leaves per plant. The seedlings were of quite high viability (Q is 0.22–0.30) and morphostructural integrity (67.8%). The output of viable seedlings (vital classes “a” and “b”) in variant 1 was 60%, variant 2 45% and variant 3 60%. Ecological-cenotic stability of G. biloba was observed repeatedly, though certain limitations on G. biloba cultivation may be that the plant is photophilic and thermophilic. But the conducted experiments show that the climatic conditions of the Ukrainian North-East are quite favourable for this species. Based on the data obtained for the Ukrainian North-East, it is possible to recommend the technology of growing G. biloba seedlings in open soil without agronetting as quite effective and low-cost.
