Article
Phytosulfokines (PSK) belong to a new class of peptide growth factors involved in intercellular signaling in plants. In this study, we examined the effect of PSK on cell division and subsequent adventitious shoot formation in protoplast-derived callus culture of Nicotiana benthamiana. Protoplast cultures and protoplast-derived calluses of N. bentha...

Key message CRISPR/Cas9-mediated introduction of a single base mutation in SOC1, a transcription factor that regulates flowering time, results in late-bolting phenotypes in lettuce. Lettuce is a widely consumed leafy vegetable crop. One of the molecular approaches that can increase leaf yield of lettuce is to delay the onset of flowering. Flowering...

Weigela subsessilis is used in folk medicine to treat pain and allergic syndromes in Korea. However, the antibacterial and anti-inflammatory activities of W. subsessilis callus extract remain unexplored. In this study, we aimed to evaluate the W. subsessilis callus of pharmacological activity. Therefore, we first established in vitro calluses of W....

To establish an efficient plant regeneration system from cell suspension cultures of Euonymus alatus, embryogenic callus formation from immature embryos was investigated. The highest frequency of embryogenic callus formation reached 50% when the immature zygotic embryos were incubated on Murashige and Skoog (MS) medium supplemented with 1 mg/L 2,4-...

Trichostatin A (TSA) is a representative histone deacetylase (HDAC) inhibitor that modulates epigenetic gene expression by regulation of chromatin remodeling in cells. To investigate whether the regulation of chromatin de-condensation by TSA can affect the increase in the efficiency of Cas9 protein-gRNA ribonucleoprotein (RNP) indel formation from...

Ultraviolet (UV)-irradiation causes an overproduction of matrix metalloproteinases (MMPs) and collagen (COL) degradation causing skin sunburn, inflammation, or photoaging in human. In this study, we prepared callus from Tiarella polyphylla D. Don ( T. polyphylla) stem and its phytochemical profiles were analyzed using HPLC-MWD. The effects of T. po...

We aimed to develop a novel technology capable of rapidly selecting mutant plant cell lines. Salt resistance was chosen as a rapid selection trait that is easily applicable to protoplast-derived cell colonies. Mesophyll protoplasts were cultured in a medium supplemented with 0, 50, 100, 150, 200, 250, and 300 mM NaCl. At NaCl concentrations ≥ 100 m...

Toona sinensis has been traditionally used to treat dysentery, enteritis, flatulence, and itchiness. However, the existence of anti-inflammatory effects of T. sinensis on Propionibacterium acnes-induced skin disease is unknown. In vitro cultures of plant cells and tissues produced under controlled conditions offer a continuous production platform f...

Histone acetylation plays an important role in plant growth and development. Here, we investigated the effect of sodium butyrate (NaB), a histone deacetylase inhibitor, on adventitious shoot formation from protoplast-derived calli and cotyledon explants of tobacco (Nicotiana benthamiana) and tomato (Solanum lycopersicum). The frequency of adventiti...
Article
Nowadays, genome editing in plants has become much easier thanks to the recently developed clustered regularly interspaced short palindromic repeat (CRISPR)-associated protein 9 (CRISPR–Cas9) nuclease system. However, to combine protoplast technology with the CRISPR–Cas9 system in plants, a stable and an efficient foreign DNA delivery system is ess...

Enhancing the competence for plant regeneration in tissue culture studies is an important issue not only for efficient genetic transformation of commercial crops but also for the reproducibility of scientific reports. In this study, we investigated optimization of several tissue culture conditions including plant growth regulators, types and ages o...
Article
We developed an efficient plant regeneration technique for turmeric (Curcuma longa L.) via somatic embryogenesis derived from embryogenic cell suspensions cultured from petioles. We initiated in vitro callus cultures from the plantlets of turmeric cultured on Murashige and Skoog (MS) medium. Then leaf, petiole, stem, and root explants of in vitro-g...
Article
Aims We developed a new rapid and reliable method for identifying bacteria using a combination of Fourier transform infrared (FT‐IR) spectroscopy of bacterial genomic DNA and multivariate analysis. Methods and Results FT‐IR spectra of genomic DNA from four type strains of Pseudomonas spp., three Escherichia spp., and two Bacillus spp. were analyze...
Article
The efficient plant regeneration system from embryogenic cell suspension cultures of Gynura procumbens (Lour.) Merr. is described. Leaf, stem and petiole explants were cultured on Murashige and Skoog (MS) medium supplemented with 2,4-dichlorophenoxyacetic acid (2,4-D) in various concentrations (0, 0.1, 0.3, 1.0 and 3.0 mg l⁻¹). Leaf, stem and petio...

To determine whether metabolite fingerprinting for whole cell extracts based on Fourier transform infrared spectroscopy (FT-IR) can be used to discriminate and compare metabolic equivalence, standard medicinal parts of Cynanchum wilfordii (Maxim.) Hemsl. and their adventitious roots were subjected to FT-IR. The principal component analysis (PCA) an...
Article
The purpose of this study is to establish the rapid discrimination system of cybrid callus lines by Fourier transform infrared (FT-IR) spectroscopy without genetic fingerprinting analysis. Genomic DNA isolated from two parental lines (Brassica oleracea var. capitata and Raphanus sativus L.) and their cybrid callus lines were analyzed by FT-IR spect...
Article
The aim of this study is to determine the feasibility of Fourier transform infrared (FT-IR) spectroscopy for simultaneous determination of saponin contents in different soybean cultivars. In cross validation between predicted content of saponin by PLS regression modeling from FT-IR spectra and measured content by HPLC, total saponin contents were p...

The conditions for efficient tuber production from suspension cultures of Pinellia ternata cells which is one of medicinal herbs were established and succinic acid in tubers propagated in vitro was determined. Leaf explants formed white nodular structures and off-white calluses at a frequency of 90.6 % when cultured on Murashige and Skoog medium su...

Fourier transform infrared spectroscopy (FT-IR) spectroscopy in combination with multivariate analysis was used to discriminate two different F1 hybrid lines from their parental inbred lines. Genomic DNA was isolated from leaves of three parental lines and two F1 hybrid lines of Brassica campestris subsp. pekinensis. Purified genomic DNA was analyz...
