Abstract

Sugar beet pulp and poly(lactic acid) (PLA) composites were prepared by compression-heating. The resultant thermoplastics had a lower density, but they had tensile strength similar to that of pure PLA specimens as well as the same geometric properties. Tensile properties depended on the initial water content of sugar beet pulp and the process by which composites were manufactured. In comparison with sugar beet pulp, the composite showed improved water resistance. This can be attributed to the hydrophobic character of PLA and pulp-matrix interactions. The composite thermoplastics showed suitable properties for potential use as lightweight construction materials.

Advances in Cytoplasmic Male Sterility in Sugar Beet from Mitochondrial Genome Structural Dynamics and Nuclear-Cytoplasmic Coordination.

Sugar beet (Beta vulgaris L.) is a globally important sugar crop whose hybrid breeding system relies heavily on cytoplasmic male sterility (CMS) lines. Recent advances in sugar beet genomics, particularly the release of high-quality reference genomes and the characterization of organellar genomes, have provided a foundation for elucidating the molecular genetic mechanisms of CMS. Furthermore, innovations in gene editing technologies are enabling transformative functional studies in this field. The precise targeting of CMS-associated mitochondrial genes and nuclear restorer-of-fertility genes not only allows for direct investigation of theoretical models governing fertility regulation through nuclear-cytoplasmic interactions but also holds promise for the targeted development of sterile and restorer lines. This review systematically summarizes progresses in sugar beet genomics, the development of gene editing tools, and the current understanding of the molecular genetics of CMS and fertility restoration in sugar beet. Although challenges remain-such as efficient delivery of editing tools into mitochondria and coordinated editing of multiple genes-the integration of genomic and gene editing technologies is expected to accelerate multi-omics-guided dissection of CMS mechanisms. These advances will facilitate the precise design of high-yield, high-sugar, and stress-resistant sugar beet hybrids, thereby providing core scientific and technological support for the sustainable development of the global sugar industry.

Alkaline degradation of invert sugar from molasses.

Sugar beet and sugar cane molasses have been shown to be suitable starting materials for producing de-icer preparations. The sucrose in the molasses is hydrolyzed to glucose and fructose by invertase. The reducing sugars are then degraded by NaOH, the alkali being neutralized by the sugar acids produced, resulting in an increase of the ionic strength and consequently depression of the freezing point of the resulting solution. For the preparation of de-icers, the desired freezing point depression to a temperature of less than about -20 degrees C can be achieved by adjusting the amount and concentration of the alkali metal hydroxide used. The resulting products are biodegradable and eliminate the corrosive effects associated with the use of conventional chloride salts. Degradation of invert sugar by NaOH has been achieved without an external heat source. The reaction products showed the same freezing point depression as seen in the degradation products from pure glucose.

Production of a full-length infectious GFP-tagged cDNA clone of Beet mild yellowing virus for the study of plant-polerovirus interactions.

The full-length cDNA of Beet mild yellowing virus (Broom's Barn isolate) was sequenced and cloned into the vector pLitmus 29 (pBMYV-BBfl). The sequence of BMYV-BBfl (5721 bases) shared 96% and 98% nucleotide identity with the other complete sequences of BMYV (BMYV-2ITB, France and BMYV-IPP, Germany respectively). Full-length capped RNA transcripts of pBMYV-BBfl were synthesised and found to be biologically active in Arabidopsis thaliana protoplasts following electroporation or PEG inoculation when the protoplasts were subsequently analysed using serological and molecular methods. The BMYV sequence was modified by inserting DNA that encoded the jellyfish green fluorescent protein (GFP) into the P5 gene close to its 3' end. A. thaliana protoplasts electroporated with these RNA transcripts were biologically active and up to 2% of transfected protoplasts showed GFP-specific fluorescence. The exploitation of these cDNA clones for the study of the biology of beet poleroviruses is discussed.
