[PMID: 39204610 PMCID: PMC11359811 DOI: 10.3390/plants13162174] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/18/2024] [Revised: 07/31/2024] [Accepted: 08/01/2024] [Indexed: 09/04/2024]
Abstract
Euonymus koopmannii is a rare and protected species in Kazakhstan, valued for its ecological role in soil stabilization and its ornamental properties. This study presents the first use of micropropagation and phylogenetic analysis for the endemic plant E. koopmannii. Seedlings of E. koopmannii proved to be more effective than internodes as primary explants for plant micropropagation of in vitro culture, with a multiplication coefficient of 28.5 from seedlings and 6.1 from internodes. On MSR I medium supplemented with 0.5 mg/L IBA and 0.05 mg/L IAA, a higher success rate of 67% was achieved for root formation of test tube-grown E. koopmannii plants. Using mannitol as an osmotic agent at a concentration of 8 mg/L prolonged the storage time of E. koopmannii under slow growth conditions when compared to CCC and abscisic acid. Phylogenetic relationships and species identification were analyzed using four DNA-barcoding markers, comparing E. koopmannii with species from NCBI. All candidate barcoding markers showed sufficient levels of interspecific genetic variation among Euonymus species. In addition, ITS region and rbcL gene sequences effectively distinguished E. koopmannii from other species. These results provide fundamental information that will be valuable for future biotechnological and molecular studies.

Wang C, Bao R, Zhang H, Shang L, Wang H, Yang Z, Du C. Study on Potato Bud Cultivation Techniques in a Greenhouse in Spring. PLANTS (BASEL, SWITZERLAND) 2023; 12:3545. [PMID: 37896009 PMCID: PMC10610138 DOI: 10.3390/plants12203545] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 09/29/2023] [Accepted: 10/11/2023] [Indexed: 10/29/2023]
Abstract
The species degeneration caused by traditional potato cultivation methods is becoming increasingly evident, and it is particularly important to study new potato cultivation methods. Sprout planting technology has the advantages of large reproductive capacity, fast growth speed, and simplified maintenance of cultivated crops. In this study, four disease-free potato varieties ('Fujin', 'Youjin', 'Zhongshu 4', and 'Feiwuruita') were treated with different parts (top bud, middle bud, and tail bud) and different bud lengths (10 cm, 15 cm, and 20 cm), and then potato sprout planting was carried out. A nutrient pot experiment was performed following a randomized complete block design (RCBD) with various replicates and a natural control (CK) treatment. By comprehensively measuring the emergence, chlorophyll content, net photosynthetic rate, dry matter distribution during the bulking period of blocks, and effect of growth and quality with bud direct seeding under both treatments, it was found that potato block top bud direct seeding cultivation is significantly superior to other parts. In terms of early maturity and yield statistics, the advantage of top bud cultivation in 'zhongshu 4' is most obvious; it reaches maturity an average of 14 days earlier, and the yield can be increased by 38.05%. Therefore, top bud direct seeding is more suitable for potato sprout planting technology. On this basis, the 20 cm and 15 cm bud length treatments of top buds were used for direct cultivation, and all the above indicators performed well. Among them, in the zhongshu 4 variety, the yields of 15 cm and 20 cm bud length treatments increased by 41.78% and 38.05%, the growth rates of commercial potatoes increased by 6% and 6.9%, respectively, and the effects were the most obvious. In conclusion, the deep research and application of potato sprouting technology has high utilization value for improving potato yield and quality and has guiding significance for greenhouse potato cultivation in early spring.

Abstract
CRISPR/Cas9 technology has become the most efficient method for genome editing in many plant species, including important industrial crops such as potatoes. This study used three target regions (T1, T2, and T3) in gbss exon I, whose sequences were first inserted into the BbsI sites in the appropriate guide RNA (gRNA) vector (pEn-Chimera, pMR203, pMR204, and pMR205), and then localized between the AtU6 promoter and the gRNA scaffold sequence. Expression vectors were constructed by introducing gRNA genes into the pMR287 (pYUCas9Plus) plasmids using the MultiSite Gateway system by attR and attL sites. The three target regions of mutant potato lines were analyzed. The use of CRISPR/Cas9-mediated multiple guide RNA-targeted mutagenesis allowed tri- or tetra-allelic mutant potato lines to be generated. Multiple nucleotide substitutions and indels within and around the three target sites caused a frameshift mutation that led to a premature stop codon, resulting in the production of gbss-knockout plants. Mutation frequencies and analysis of mutation patterns suggested that the stably transformed Cas9/multiple guide RNA expression constructs used in this study can induce targeted mutations efficiently in the potato genome. Full knockout of the gbss gene was analyzed by CAPS, Sanger sequencing and iodine staining. The present study demonstrated successful CRISPR/Cas9-mediated multiple guide RNA-targeted mutagenesis in the potato gbss gene by Agrobacterium-mediated transformation, resulting in an amylose-free phenotype.

Somaclonal Variation for Genetic Improvement of Starch Accumulation in Potato ( Solanum tuberosum) Tubers. PLANTS (BASEL, SWITZERLAND) 2023; 12:232. [PMID: 36678944 PMCID: PMC9865851 DOI: 10.3390/plants12020232] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 12/25/2022] [Accepted: 12/31/2022] [Indexed: 06/17/2023]
Abstract
Starch content is one of the major quality criteria targeted by potato breeding programs. Traditional potato breeding is a laborious duty due to the tetraploid nature and immense heterozygosity of potato genomes. In addition, screening for functional genetic variations in wild relatives is slow and strenuous. Moreover, genetic diversity, which is the raw material for breeding programs, is limited due to vegetative propagation used in the potato industry. Somaclonal variation provides a time-efficient tool to breeders for obtaining genetic variability, which is essential for breeding programs, at a reasonable cost and independent of sophisticated technology. The present investigation aimed to create potato somaclones with an improved potential for starch accumulation. Based on the weight and starch content of tubers, the somaclonal variant Ros 119, among 105 callus-sourced clones, recorded a higher tuberization potential than the parent cv Lady Rosetta in a field experiment. Although this somaclone was similar to the parent in the number of tubers produced, it exhibited tubers with 42 and 61% higher fresh and dry weights, respectively. Additionally, this clone recorded 10 and 75% increases in starch content based on the dry weight and average content per plant, respectively. The enhanced starch accumulation was associated with the upregulation of six starch-synthesis-related genes, namely, the AGPase, GBSS I, SBE I, SBE II, SS II and SS III genes. AGPase affords the glycosyl moieties required for the synthesis of amylose and amylopectin. GBSS is required for amylose elongation, while SBE I, SBE II, SS II and SS III are responsible for amylopectin.

Saudi J Biol Sci 2021; 29:2541-2551.

Abstract
Salinity and drought stress, which combines a lack of water and sodium toxicity, are more of the problems faced by plants and agricultural crops in newly reclaimed lands. Therefore, the direction of our research is to produce salinity-tolerant plants to increase the productivity of crops under conditions of salt stress. Potato callus was studied using different concentrations of NaCl (0.0, 50, 75, 100, 125, 150 and 200 mM). Shoot induction was obtained from callus treated with MS medium containing 4.0 and 5.0 mg l−1TDZ + 0.5 mg l−1 GA3 with NaCl up to 125 mM and 150 mM for Rosetta and Victoria, respectively. When plantlets were cultured on MS medium containing 3.0 mg l−1 kinetin and 1.0 mg l-1paclobutrazol (PBZ) with 80 or 90 g l−1 sucrose after two months gave a good microtuber per explant of Rosetta and Victoria cultivar which gave number of microtuber/plantlet (1.85) and (2.40) when plantlets treated with 125 mM and 150 mM NaCl of Rosetta and Victoria cultivar, respectively. In general, the results were shown in each treatment of NaCl and that amounts of proline at 125 and 150 mMNaCl were significantly more than 0.0, 50, 75 and 100 mM NaCl. This result is related to the role of proline in the osmotic adjustment of a higher concentration of salinity. The results showed that the amounts of sodium increased with increasing the salt concentration, but the amount of potassium decreased and also increased the Na+/K+ ratio with increasing the salt concentration. This research is important for in vitro potato plant regeneration, which requires optimization before genetic transformation can be achieved.
