“…The increased level of chlorophyll in F1 also correlates with the increased expression of chlorophyll biosynthetic genes and decreased expression of the degradation genes in contrast to amphidiploid. Relative chlorophyll content was found to be similar in haploid, diploid and tetraploid plants of Ricinus communis [37]. Sometimes increase in chlorophyll content in interspeci c hybrid F1 could be related to sterility [38,39].…”

Background In order to understand the developmental modulation of transcriptome and associated gene expression in inter-genomic combinations, a systematic study was planned using two diverse yet closely related species of Ocimum, targeting their hybrid F1 and derived amphidiploid (colchiploid of F1 hybrid). The existing developmental alterations between F1 and amphidiploid through phenotypical and anatomical assessments were analyzed. Results Study of several genes and transcription factors putatively involved in the growth and developmental processes of plants clearly amalgamates the transcriptome data linking the phenotypic differences in F1 and amphidiploid. Additionally, differentially expressed genes of stomatal patterning and development revealed their involvement leading to higher density of stomata in F1 while larger size of stomata in the amphidiploid. Absence of 8,330 transcripts of interspecific hybrid F1 in its amphidiploid and exclusive presence of two detected transcripts in amphidiploid provides a set of genes to analyze the suppressed or activated functions between F1 and amphidiploid. Estimation of chlorophyll, lignin, flavonoid and phenylpropenes (eugenol and methyleugenol) content were correlated with the average FPKM and digital gene expression values in F1 and amphidiploid. Conclusion This is the first investigation which describes the genes and transcription factors influenced by interspecific hybridization leading to developmental changes and alleviation of intergenomic instability in amphidiploid.

“…Further introduction of sudangrass in the Lower Volga region depends on the creation of fun-damentally new varieties having high-yield and early mature, which are adapted to modern cultiva-tion technologies. The selection of sorghum crops, including sudangrass is focused on the use of the genetic function of the plant cytoplasm [8,9,10], heterosis [11,12], the study of the concentration and modification of kafirins [13]; protein modulation [14]; expression of apomictic potentials [15]; genetic modification as a tool to increase nutritional value [16,17,18].…”

The article characterizes the advantages of sudangrass, presents its comparative assessment, and gives recommendations for the cultivation of a new variety Evgeniya for seeds. Implementation of the program for the development of forage production in Russia and other countries implies not only the creation of new varieties but also the promotion of their introduction. This study aims to test the new variety Evgeniya of sudangrass and refine the cultivation techniques for obtaining high-quality seeds in the Volga region. For a period of 2 years, we studied the new promising variety, new lines that were obtained during interspecific, intraspecific, and intervarietal crossings carried out in different years, and new varieties of sudangrass recommended for cultivation in the region. The Yubileinaya 20 and Zonalskaya 6 varieties of sudangrass were used as standards. Field studies were carried out in 2017-2019. It was found that the new variety Evgeniya was characterized by high values of economically valuable traits. The variety had several biometric and biological features, such as thin stems and high yields, so we studied the influence of sowing methods and seeding rates not only on yield but on seed quality. To obtain the maximum yield of high-quality seeds, Evgeniya sudangrass must be sown with a seeding rate of 0.6-0.7 mln. viable seeds per hectare and row spacing of 30 cm.
