Development and validation of whole-genome SSR markers in sugar beet (Beta vulgaris L.).

Sugar beet (Beta vulgaris L.) is an important sugar and cash crop worldwide. To systematically characterize SSR (Simple Sequence Repeat) loci across sugar beet chromosomes and enable the precise identification of germplasm resources, this study conducted a genome-wide scan for SSR loci, analyzed their distribution patterns, and determined their genotypes using resequencing data from 123 sugar beet varieties. The results revealed an abundance of SSR loci in the sugar beet genome, with a total of 135, 379 identified, from which 135, 344 pairs of SSR primers were designed (135, 344 primer pairs successfully designed; 35 loci failed to meet design criteria). Specifically, 31, 748 primer pairs were designed based on SSRs located in unassigned scaffolds, and 103, 596 primer pairs from SSRs assigned to the nine chromosomes. Through bioinformatic analysis, we identified 28, 768 SSR primers located in multi-copy genes with PIC (Polymorphism Information Content) ≥ 0.5, and 2, 326 SSR markers located in single-copy genes residing in various genic regions (among which 543 had PIC ≥ 0.5, with the highest reaching 0.776). PCR (Polymerase Chain Reaction) validation confirmed 20 robust and polymorphic markers producing clear and reproducible bands. Among them, 10 SSR primers located in multi-copy genes exhibited three or more polymorphic types, and 10 markers located in single-copy genes displayed 2-3 polymorphic types. The most polymorphic marker, YCD-4-2, detected 11 polymorphic types across 48 varieties. Furthermore, to explore markers with potential functional significance, we annotated the genes harboring SSR markers located in single-copy genes. The results showed that 1, 264 SSRs located in single-copy genes were localized to 967 genes, which are significantly enriched in pathways related to carbohydrate metabolism, stress responses, and plant-pathogen interactions. The 20 validated markers and the 2, 326 SSRs located in single-copy genes provided in this study can be directly applied to fingerprinting of sugar beet varieties, seed purity testing, and marker-assisted selection, thus representing a practical resource for molecular breeding.

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.

[Effect of high-carbohydrate diet in the form of sugar beet on glucose and ketone body levels in the blood serum of highly pregnant and freshly lactating cows].

In an experiment using 24 high-yielding cows (3rd and 6th lactations), group II was fed sugar beet as carbohydrate source (2 kg DM per animal and day) for 4 weeks before and for 4 weeks after parturition, whilst group I was given the equivalent amount of dried spent beet pulp. Sugar beet feeding during the dry period caused the glucose level in the blood to rise significantly from 48 to 55 mg/100 ml. On the 21st day of lactation the glucose concentration in group II (27 mg) had declined more strongly than in group I (37 mg). Feeding large amounts of easily soluble carbohydrates during the dry period obviously inhibits gluconeogenesis during early lactation. The ketone body level of group II was found to rise to 14 mg/100 ml by the 21st day of lactation (group I--4 mg), a level indicative of ketosis. The ketogenous action (strong formation of butyric acid in the rumen) of sugar beet enhances this effect, too. The daily milk yield did not vary much coming to 26.8 and 27.8 kg in the control and in the experimental group, respectively. The results allow to conclude that feeding fresh sugar beet to high-yielding cows just before and shortly after parturition is not advisable.

Studies of the mycoparasitism in rhizosphere of emerging sugar-beet.

Pythium oligandrum Drechsler was found as a very weak pathogen of emerging sugar-beet by means of the inoculation of the sterilized soil. The hyperparasitic ability of Pythium oligandrum Drechsler to relative species, viz. Pythium ultimum Trow and Pythium debaryanum (Hesse) were proved in rhizosphere of emerging sugar-beet. The rhizosphere soil inoculation by P. ultimum resulted in the sugar-beet emergence about 3% while the sugar-beet emergence achieved 110% if P. ultimum and P. oligandrum were inoculated simultaneously. The sugar-beet emergence due to the dual inoculation of rhizosphere soil by P. ultimum and P. debaryanum was about 3%, whereas due to P. ultimum, P. debaryanum, and P. oligandrum 77%.

[Aneuploids from the progeny of triploid sugar beets].

The crossing of sugar beet triploids with triploids (3x X 3x) produced 25.1 +/- 5.16% of aneuploids, the crossing of triploids with tetraploids (3x X 4x) resulted in 17.7 +/- +/- 2.66% of aneuploids, and the crossing of triploids with diploids (3x X 2x) yielded 12.4 +/- 2.36% of aneuploids. In the combinations 3x X 2x and 3x X 4x all the theoretically possible forms of aneuploids were observed. After free pollination of aneuploids with different numbers of chromosomes their progenies comprise 71.4 +/- 2.18% of euploids and 28.6 +/- 3.31% of aneuploids.

Fate of chloroalkylene-9-14C in carrots, sugar beets, and soil under outdoor conditions.

Immediately after application of chloroalkylene-9-14C to soil (1.32 ppm, based on dry weight of soil in the upper layer of 0 to 10 cm) under outdoor conditions, carrots were sown; in the following year, sugar beets were grown. About 80% of the radioactivity applied volatilized within one vegetation period. Most of the remaining radioactivity was still in the upper soil layer; 0.8% had dispersed to a depth of 40 cm, and 3.3% was taken up by the carrot plants. In the second year, no more decreases of soil residues was observed; uptake by sugar beets was 0.1% of the applied radioactivity. In the first year, the residues in the upper soil layer consisted of 41% unchanged chloroalkylene-9, 19% soluble metabolites, and 40% unextractable residues; the amount of unextractable residues rose to 68% in the second year. The following conversion products were characterized in the soil extracts: a monohydroxylated dichlorobiphenyl, a monomethoxylated dichlorobiphenyl, and two isomeric monohydroxylated, monoisopropylated dichlorobiphenyls; in carrot roots, a monomethoxylated dichlorobiphenyl was detected. Conjugates occurring in the soil yielded, after acid hydrolysis, a monohydroxylated dichlorobiphenyl among other compounds.

Hide and seek: de novo identification in sugar beet reveals impact of non-autonomous LTR retrotransposons.

Plant genomes are filled with retrotransposons and their derivatives, constantly undergoing sequence diversification and structural rearrangement. Among them, short, non-autonomous retrotransposons lack full coding capacity and often form subfamilies. As a result, non-autonomous retrotransposons are incompletely identified in most to all genome assemblies.Here, we capitalize on our comprehensive understanding of the transposable element (TE) landscape in sugar beet (Beta vulgaris) to assess the extent of the blind spot for non-autonomous long terminal repeat (LTR) retrotransposons. This use case serves to answer if all of these sequences are derivatives of easier-to-identify full-length elements or if there is more variability that is currently overlooked.For this we applied a semi-automated structural discovery workflow followed by in-depth manual verification to characterize non-autonomous LTR retrotransposons in sugar beet. We retrieve more than 100 non-autonomous LTR retrotransposon families that lack complete autonomous coding capacity, including canonical terminal-repeat retrotransposons in miniature (TRIMs), elongated non-coding derivatives and families retaining fragmented coding remnants. The identified families span a broad range, including elements exceeding 15,000 bp in length and display evidence for reshuffling and modular evolution. Only a subset of families could be confidently linked to autonomous retrotransposons, showing sequence diversification within the non-autonomous LTR retrotransposon fraction beyond the autonomous genomic templates.We highlight that a large fraction of non-autonomous LTR retrotransposons is incompletely recovered with the current TE identification workflows, even if the output is well-curated and condensed into TE libraries and suggest procedures to remedy this gap. This study gives a genome-wide view into the non-autonomous LTR retrotransposon landscape of a single plant genome and highlights the importance of structure-based approaches for their identification and classification.

Membrane-bound potassium and magnesium ion-stimulated inorganic pyrophosphatase from roots and cotyledons of sugar beet (Beta vulgaris L).

1. The 25 000-30 000 X g fraction from sugar beet leaf or roots contains, together with (Na+ plus K+)-activated ATPase, also K+-stimulated inorganic pyrophosphatase. 2. This inorganic pyrophosphatase is also stimulated by Rb+ and to a lesser degree by Li+ and Na+. 3. Na+ is at the same time an inhibitor to the K+-stimulation of the inorganic pyrophosphatase. 4. No signs of synergism for (Na+ plus K+) were found. 5. Optimum pH was at about 8.5.

Determination of benomyl, carbendazim and 2-aminobenzimidazole (2-ab) in plant materials. Part I: Apples, red-currants, grapes, kale and sugar beets.

Benomyl and Carbendazim are widely used fungicides with systemic activity. In the Federal Republic of Germany the legal limits of Benomyl and Carbendazim lie between 0.1 and 7 ppm dependent on the substrate. A method for the determination of Benomyl and Carbendazim in apples, red-currants, grapes, kale, and sugar beets was developed. Benomyl and Carbendazim are extracted with ethyl acetate, saponified and determined as 2-aminobenzimidazole by thin-layer chromatography. The detection limits lie between 0.02--0.08 ppm, recoveries amount to 87% at 0.5-ppm levels.

[Improvement in the quality of rape seed by combining silage with fodder sugar beets. 1. Quality evaluation of the silages].

Industrial-scale studies showed that the addition of rape-seed flakes to half sugar mangels improves the feeding value and the quality of the silages. Furthermore, it was found that the development of yeasts was inhibited and that the propagation of acidifiers was retarded as the proportion of rape-seed increased. The microbiological analysis indicates that the amount of rape-seed added to the half sugar mangels should not exceed 10%.
