    Bo Hwan Kim1,#, Sheikh Mansoor2,#, Gyung Deok Han3, Ji Eun Park4, Wook Kim1,*, Yong Suk Chung2,*

    Phyton-International Journal of Experimental Botany, Vol.93, No.9, pp. 2339-2347, 2024, DOI:10.32604/phyton.2024.056439 - 30 September 2024

    Abstract Recognizing the variation of genetic resources is the first step in selection. One of the most important variations in grain crops is the uniformity of seed grain weight, which can be converted into seed size. However, it has been challenging since it needs high labor costs and time to measure it on a large scale. The current study used an image analysis technique to measure the grain seed area of about 100 seeds per accession with 64 germplasm of Tartary buckwheat (Fagopyrum tataricum) to study variation among and within them. To understand the nature of variation, More >

    Phyton-International Journal of Experimental Botany, Vol.93, No.4, pp. 699-712, 2024, DOI:10.32604/phyton.2024.048469 - 29 April 2024

    Abstract To mitigate the wastage of seed resources and reduce the usage of pesticides and fertilizers, seed coating agents have gained popularity. This study employs single-factor and multi-index orthogonal experimental design methods to investigate the seed coating formula and physical properties of Tartary buckwheat. The specific effects of each component on Tartary buckwheat seed germination are analyzed. The findings reveal that the seed coating agent formulated with 1.5% polyvinyl alcohol, 0.15% sodium alginate, 0.2% op-10, 0.1% polyacrylamide, 8% colorant, 3% ammonium sulfate, 1% potassium dihydrogen phosphate, and 0.15% carbendazim exhibits the most effective coating. It demonstrates… More >

    Abstract

    Aluminum (Al) toxicity is a considerable factor limiting crop yield and biomass in acidic soil. Tartary buckwheat growing in acidic soil may suffer from Al poisoning. Here, we investigated the influence of Al stress on the growth of tartary buckwheat seedling roots, and the alleviation of Al stress by silicon (Si), as has been demonstrated in many crops. Under Al stress, root growth (total root length, primary root length, root tips, root surface area, and root volume) was significantly inhibited, and Al and malondialdehyde (MDA) accumulated in the root tips. At the same time, catalase (CAT)

    Xiaodong Shi1,*, Yue Qi1, Liangzhu Lin1, Jia Wang1, Xiaobo Qin2, Bei Niu3,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.11, pp. 3149-3162, 2023, DOI:10.32604/phyton.2023.027324 - 24 October 2023

    Abstract Tartary buckwheat (Fagopyrum tataricum) is a dual-purpose medicinal and food crop grown for its high contents of functional compounds and abundant nutrients. Although studies have shown the differences of total flavonoid content in Tartary buckwheat at different ploidy levels, the composition of flavonoid and its regulatory mechanisms are largely unknown. In this study, the leaf metabolome and transcriptome of diploid and tetraploid accessions of Tartary buckwheat were analyzed to gain insight into the impact of polyploidization on comparative secondary metabolite composition and molecular regulatory mechanism. Based on a widely targeted metabolomics analysis, a total of 792… More >

    Abstract Tartary buckwheat (Fagopyrum tataricum) is an important pseudocereal feed crop with medicinal and nutritional value. Drought is one of the main causes of reduced growth and yield in these plants. We investigated the growth, physiological, and metabolic responses of the widely promoted Tartary buckwheat variety Chuan Qiao No. 1 to polyethylene glycol (PEG)-mediated drought stress. Drought significantly decreased shoot length, shoot biomass and relative water content. Root length, malondialdehyde content, electrolyte leakage, activities of superoxide dismutase, peroxidase, catalase and amylase, and contents of soluble sugar, soluble protein and proline were increased by PEG-mediated drought. Untargeted metabolomics… More >

    Analysis of Seed Phenotypic and Metabolic Characteristics of Diploid and Tetraploid Tartary Buckwheat

    Xiaodong Shi1,*, Cong Wang1, Wenjian Li1, Hanlei Xiao1, Yanjie Li1, Bei Niu2,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.9, pp. 1973-1986, 2022, DOI:10.32604/phyton.2022.020065 - 13 May 2022

    Abstract Polyploid plants grow well, are stress tolerant, and are rich in nutrients and bioactive compounds. Thus, they are useful for improving crop quality and yield. In this study, we compared the seed characteristics and metabolite profiles of diploid and tetraploid tartary buckwheat, which was developed via an artificially induced chromosome doubling event. The length, width, area, and thousand-grain weight were greater for the tetraploid seeds than for the diploid seeds. However, the germination rate decreased for the tetraploid seeds. Additionally, there was a gap between the shell and kernel of the tetraploid seeds. Moreover, the… More >

    Physiological and Biochemical Mechanisms of Exogenous Calcium Chloride on Alleviating Salt Stress in Two Tartary Buckwheat (Fagopyrum tataricum) Varieties Differing in Salinity Tolerance

    Tao Zhang*, Hongbing Yang

    Phyton-International Journal of Experimental Botany, Vol.91, No.8, pp. 1643-1658, 2022, DOI:10.32604/phyton.2022.019572 - 14 April 2022

    Abstract Salt stress is one of the most serious abiotic stresses limiting plant growth and development. Calcium as an essential nutrient element and important signaling molecule plays an important role in ameliorating the adverse effect of salinity on plants. This study aimed to investigate the impact of exogenous calcium on improving salt tolerance in Tartary buckwheat cultivars, cv. Xinong9920 (salt-tolerant) and cv. Xinong9909 (salt-sensitive). Four-week-old Tartary buckwheat seedlings under 100 mM NaCl stress were treated with and without exogenous calcium chloride (CaCl2), Ca2+ chelator ethylene glycol tetraacetic acid (EGTA) and Ca2+-channel blocker lanthanum chloride (LaCl3) for 10 days.… More >

    Dabing Xiang1,#, Yue Song1,#, Chao Song2, Yan Wan1, Xueling Ye1, Changying Liu1, Chenggang Liang3, Gang Zhao1,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.8, pp. 1659-1669, 2022, DOI:10.32604/phyton.2022.020338 - 14 April 2022

    Abstract A low seed-setting rate is the main limiting factor influencing Tartary buckwheat production under high-yield cultivation conditions. To investigate the seed setting and its spatial characteristics, two Tartary buckwheat cultivars (high seed-setting rate cultivar Qianku 3; low seed-setting rate cultivar Liuku 3) were compared by a two-year field trial in 2017 and 2018. The results showed that the Tartary buckwheat underwent simultaneous flowering and fruiting. Flowers, generated from branch, were still blooming during the mature stage of grains on stem, which resulting in a greater number of flowers and grains on the branch than those… More >

    Abstract Common buckwheat (Fagopyrum esculentum), a specialty crop in southwest China, is not only used as a supplement to primary grain crops but also to produce beverages, such as tea and wine. To fully exploit the products made from common buckwheat flower, ultra-performance liquid chromatography–electrospray ionization– tandem mass spectrometry (UPLC–ESI–MS/MS) was conducted to analyze the metabolites in red- (‘Guihong 2’) and white-flowered (‘Fengtian 1’) buckwheat cultivars. A total of 784 metabolites were identified of which flavonoids were the largest group with 191 components, followed by organic acids and derivatives (126), and amino acids and derivatives (95). Besides, More >

    Phyton-International Journal of Experimental Botany, Vol.90, No.3, pp. 871-893, 2021, DOI:10.32604/phyton.2021.014242 - 30 March 2021

    Abstract Rice-Tartary buckwheat (RTB) is a special germplasm of Tartary buckwheat. In this study, the appraisal of taste quality between RTB and conventional Tartary buckwheat (CTB) was presented, and the metabolites in kernels at three typical grain filling stage (GFS) were investigated. Unlike CTB, RTB showed thin shell seeds without longitudinal furrows at maturity, which was easily artificially dehulled. Sense organ test indicated that RTB exhibited better taste quality because of the higher values of appearance, viscosity, taste and summary were appraised. In total, 92 metabolites were identified in kernels using GM-MS metabolomics platform. The levels… More >
