The work aimed at creating tetraploid lines of Miscanthus sinensis and Miscanthus sacchariflorus species. To achieve this goal, we used methods of microclonal propagation, fluorescence cytophotometry, and genomic status differentiation using computer software of AP ‘Partec’ (Germany). It was found that the percentage of cultivated shoots of Miscanthus sacchariflorus for an exposure period of 1 day was 18.86 ± 5.37%. To compare, it was51.78 ± 6.51% in Miscanthus sinensis. The best indicators of tetraploid induction in Miscanthus sinensis were observed for the exposure to colchicine for 2 days with polyploidization efficiency of 31.25% and 21.42%, and in Miscanthus sacchariflorusf or 2 hours and 6 hours with rates of 35.0% and 27.3%, respectively. To stabilize the tetraploid level of genome ploidy, we used Murashige and Skoog liquid media (1962) supplemented with 0.005% colchicine and an exposure period of myxoploids for 6 hours. The flowering of new tetraploid clones in the conditions of Ukraine was observed on the second year of vegetation in late September and the beginning of October with the formation of fertile pollen grains. However, development of a microgametophyte depends on temperature conditions, both for Miscanthus sinensis (4x) and Miscanthus sacchariflorus (4x). Breeding schemes for the formation of anisoploid populations have also been developed: M sinensis (4x) x M sinensis (2x); M. sa?chariflorus (4x) x M sinensis (2x); M sinensis (4x) x M. sachariflorus (2x)

Abstract Since 2013, the sugarcane aphid, Melanaphis sacchari Zehntner, has been a perennial pest to U.S. sorghum, Sorghum bicolor (L.) Moench, production with yield declines in susceptible hybrids ranging from 50 to 100%. Previous studies have found that a single clonal genotype predominates in samples collected from sugarcane (Saccharum spp.), sorghum, and Johnsongrass (Sorghum halepense [L.] Persoon), from 2013 to 2017 in the continental United States. We sought to determine if the “super-clone” persists in sugarcane aphid samples collected in 2018 from five U.S. states and one territory and to identify the multilocus lineage of samples collected in 2018–2019 from a new host, giant miscanthus, Miscanthus sinensis× Miscanthus sacchariflorus Greef & Deuter ex Hodkinson & Renvoize. Thirty-one samples collected from Columbus grass (Sorghum almum Parodi), Johnsongrass, sorghum, and giant miscanthus in 2018 were genotyped using 9 simple sequence repeat markers; 29 samples had identical alleles to the multilocus lineage F super-clone. All samples (n = 7) collected from giant miscanthus in 2018–2019 also had identical alleles to the predominant genotype.

Fifteen tall, warm-season, native and ornamental grasses were subjected to a 3-year, low-input, and cold hardiness trial conducted from 2010 to 2013 in zone 4a at Fargo and Mandan, ND. Grasses tested were big bluestem [species (Andropogon gerardii)], ‘Pawnee’ big bluestem (A. gerardii), silver banner grass (Miscanthus sacchariflorus), giant miscanthus (Miscanthus ×giganteus), hardy pampas grass, (Saccharum ravennae), and the following maidengrass (Miscanthus sinensis) cultivars: Silver Feather, Narrow Leaf, Blondo, Autumn Light, Condensatus, Grosse Fontaine, Morning Light, Gracillimus, Strictus, and Zebrinus. In addition to survival, the grasses were also rated for spring vigor and fall quality (0–10 scale for both evaluations), fall leaf length, and fall flower height. The grasses received no management during the trial other than irrigation during the first season and weed control. The grasses were exposed to subsurface soil temperatures (at 6-inch depth) that reached as low as −8.6 °C at the Fargo location and −6 °C at the Mandan location. The study revealed that all big bluestem (species), ‘Pawnee’ big bluestem, and silver banner grass survived at both locations; silver banner grass scored the highest spring vigor ratings; silver banner grass and ‘Pawnee’ big bluestem scored the highest fall quality ratings; silver banner grass produced the longest fall leaf length; and ‘Pawnee’ big bluestem, big bluestem (species), and silver banner grass produced the tallest fall flowers.

The lignocellulosic perennial crop miscanthus, especially Miscanthus × giganteus, is particularly interesting for bioenergy production as it combines high biomass production with low environmental impact. However, there are several varieties that pose a hazard due to susceptibility to disease. This review contains links showing genotype and ecological variability of important characteristics related to yield and biomass composition of miscanthus that may be useful in plant breeding programs to increase bioenergy production. Some clones of Miscanthus × giganteus and Miscanthus sinensis are particularly interesting due to their high biomass production per hectare. Although the compositional requirements for industrial biomass have not been fully defined for the various bioenergy conversion processes, the lignin-rich species Miscanthus × giganteus and Miscanthus sacchariflorus seem to be more suitable for thermochemical conversion processes. At the same time, the species Miscanthus sinensis and some clones of Miscanthus × giganteus with low lignin content are of interest for the biochemical transformation process. The species Miscanthus sacchariflorus is suitable for various bioenergy conversion processes due to its low ash content, so this species is also interesting as a pioneer in breeding programs. Mature miscanthus crops harvested in winter are favored by industrial enterprises to improve efficiency and reduce processing costs. This study can be attributed to other monocotyledonous plants and perennial crops that can be used as feedstock for biofuels.

AbstractDespite its economic importance as a new biofuel resource, little work has been done on the large-scale phylogenetics of Miscanthus. Twenty-three complete Miscanthus chloroplasts were assembled and annotated. A phylogeny was performed with these assemblies, which shows the relationships between the main Miscanthus species and sub-species. The phylogeny demonstrates that there is no meaningful distinction between Miscanthus floridulus and Miscanthus transmorrisonensis as the accessions are not distinct. However, at the crown of the tree there is a clear distinction between M. sinensis malepartus and M. sinensis condensatus subspecies. The phylogeny reaveals that the female parent of Miscanthus xgiganteus is Miscanthus lutarioriparius rather than Miscanthus sacchariflorus. The phylogeny also shows a novel hybrid between Miscanthus oligostachyus and Miscanthus sinensis, a grouping to which Miscanthus sinensis var Purpurascens belongs. This hybrid form is named Miscanthus ×oligostachyus.

The bio-based economy concept requires using biomass not only for energy production but also for bioactive compound extraction, application or biotransformation. This study analyzed the possibility of obtaining bioactive compounds from biomass before its transformation into biofuel. This involved an analysis of the total content of polyphenols (TPC), flavonoids (TFC), and spectral analysis using Fourier transform infrared spectroscopy (QATR- FTIR) as well as analysis of the antioxidant activity of extracts from selected perennial herbaceous crops cultivated on marginal lands in Poland. The extracts were obtained by supercritical carbon dioxide extraction (scCO2) or scCO2 with water as a cosolvent (scCO2/H2O) from biomass of the following plants: Helianthus salicifolius, Silphium perfoliatum, Helianthus tuberosus, Miscanthus × giganteus, Miscanthus sacchariflorus, Miscanthus sinensis and Spartina pectinata. The biomass was harvested twice during the growing period (June and October) and once after the end of the growing period (February). For most of the analyzed extracts obtained from biomass at the growing stage using scCO2 or scCO2/H2O, a higher TPC was noted than for samples of semi-wood or straw biomass obtained after the end of the growing period. Higher contents of polyphenolic compounds were recorded in extracts obtained using scCO2/H2O. A positive correlation between TPC and antioxidant activity was noted for the analyzed substrates. Flavonoid contents varied in the analyzed samples, and higher contents were generally obtained in scCO2 extracts from biomass harvested at the beginning of the growing period. A high diversity of extract compositions was confirmed by spectral analysis. The presented data can be used at the initial stage of planning a biorefinery.
