“…To obtain a global view of the tissue specific characteristics at the transcriptional level between KFJT-1 and KFJT-CK at seedling stage, total six DGE libraries from roots, stems and leaves were sequenced with Solexa/Illumina DGE analysis, respectively (Dong et al, 2017). In root, a total of 557 genes were up-regulated and 160 genes were down-regulated.…”

Sweet sorghum [Sorghum bicolor (L.) Moench] is a C 4 plant characterized by a high photosynthetic efficiency and a high biomass-and sugar-yielding crop. However, the current varieties of sweet sorghum cannot meet the rapid growth demand for bio-ethanol production because of its low sugar content in China. To breed novel varieties to provide excellent raw materials for bio-ethanol production, the dry seeds were irradiated by carbon ion beam irradiation with different doses in sweet sorghum, resulting in acquiring an early-maturity mutant at 80 Gy dose, which the growth period was stably shortened for around 20 days compared to wild-type plant. In this paper, we briefly summarized the biological effects induced by carbon ion beam, the characters of early-maturity mutant, and revealed corresponding mechanisms from the point of view of morphological, physiological and molecular levels. In conclusion, there were significant effects on sweet sorghum irradiated by carbon ion beam.

“…Moreover, our study indicated that KFJT-1 was able to not only flower but also produce mature grain, which an insert fragment GA was found in KFTJ-1 and the corresponding fragment was not found in KFJT-CK for the Hd3a gene by further research (Dong et al, 2015). Functional analysis of gene ontology indicated that genes involved flowering time were also enriched such as "response to far red light", "pollen development" including "auxin transport", which consist with the short growth cycle of KFJT-1 compared to KFJT-CK (Dong et al, 2017). At present, KFJT-1 has been identified by the Gansu provincial variety Approval Committee after regional trial and production test for several years , which can solve the difficult problem of earlier frost during industrialization plant for bio-ethanol production using sweet sorghum as feedstock in the northwest region of China.…”

Sweet sorghum [Sorghum bicolor (L.) Moench] is not only an efficient and highly productive bioenergy crop that may help alleviate potential food-fuel tension caused by over-reliance on corn grain ethanol because of its outstanding features, including large amounts of fermentable carbohydrates in its juice-rich stalks, drought-tolerance, saline-alkaline resistance but also has considerable potential as food, forage crop owing to the limited availability of arable land. In this review, we have provided a brief overview of the progress that has been made in sweet sorghum industrialization at IMP range from research motivation, breeding, planting scale to products development. A conclusion is drawn that sweet sorghum industry is a systematic project, involving many key points, such as breeding, planting, production process and products sale. From a strategic and sustainability point of view, sweet sorghum is one of the most promising plants, particularly for ethanol, silage and liquor production.

“…Using DNA microarray techniques, Hwang et al (2014) found that 220 MeV l À1 carbon ions (LET = 107 keV l À1 ) can induce up-regulated gene expression related to sugar and starch accumulation in rice. In another study by Dong et al (2016b), an early-maturity sweet sorghum mutant KFJT-1 has been obtained after carbon ion irradiation; through comparative gene expression analysis between the KFJT-1 mutant and the wild-type KFJT-CK, the down-regulated PHYA gene was conferred to result in high sucrose content accumulation in KFJT-1. However, combined omics assays and the promising microbial mutants induced by heavyion irradiation to investigate the involved mechanisms have not been reported.…”

Significance and Impact of the Study: There is currently a great interest in developing rapid and diverse microbial mutation tool for strain modification. Heavy-ion mutagenesis has been proved as a powerful technology for microbial breeding due to its broad spectrum of mutation phenotypes with high efficiency. In order to deeply understand heavy-ion mutagenesis technology, this paper briefly reviews recent progress in microbial breeding using heavy-ion mutagenesis at IMP, and also presents the outline of the beam line for microbial breeding in Heavy Ion Research Facility of Lanzhou (HIRFL) as well as new insights into microbial biotechnology via heavy-ion mutagenesis. Thus, this work can provide the guidelines to promote the development of novel microbial biotechnology cross-linking heavy-ion mutagenesis breeding that could make breeding process more efficiently in the future. Abstract Nowadays, the value of heavy-ion mutagenesis has been accepted as a novel powerful mutagen technique to generate new microbial mutants due to its high linear energy transfer and high relative biological effectiveness. This paper briefly reviews recent progress in developing a more efficient mutagenesis technique for microbial breeding using heavy-ion mutagenesis, and also presents the outline of the beam line for microbial breeding in Heavy Ion Research Facility of Lanzhou. Then, new insights into microbial biotechnology via heavy-ion mutagenesis are also further explored. We hope that our concerns will give deep insight into microbial breeding biotechnology via heavy-ion mutagenesis. We also believe that heavy-ion mutagenesis breeding will greatly contribute to the progress of a comprehensive study industrial strain engineering for bioindustry in the future.
