Zat goniotalamin pada tanaman gajah beranak (Goniothalamus tapis) merupakan obat alternatif penyembuhan kanker. Penelitian bertujuan untuk mendapatkan zat goniotalamin melalui kultur kalus dan kultur suspensi sel. Metode penelitian eksperimen Rancangan Acak Lengkap (RAL) dengan kombinasi 2,4-D (1-10 mgL-1) dan BAP (0,5-2 mgL-1) menggunakan eksplan batang muda, terdiri dari 17 perlakuan dan 3 kali ulangan. Analisis data menggunakan Analysis of Variances dan uji lanjut Duncan Multiple Range Test (DMRT) taraf 5%. Hasil menunjukkan bahwa kultur kalus G. tapis pada media 5,0 mg L-1 2,4-D + 1 mg L-1 BAP adalah yang terbaik dengan waktu muncul kalus 28,33 hari dan persentase pembentukan kalus 100%. Kalus untuk kultur suspensi sel bertekstur remah dan berwarna kuning kehijauan. Kultur suspensi sel menghasilkan pertumbuhan sel yang cepat, tidak lembek berair dan mudah dipisahkan. Hasil kualitatif Kromatografi Lapis Tipis kultur suspensi sel sangat jelas, bersih dan terdapat potensi kandungan zat goniotalamin pada perlakuan 2,4-D 5 mg L-1 + BAP 0,5 mg L-1, 2,4-D 5 mg L-1 + BAP 1 mg L-1, 2,4-D 5 mg L-1 + BAP 2 mg L-1, 2,4-D 10 mg L-1 + BAP 0,5 mg L-1 dan 2,4-D 10 mg L-1 + BAP 1 mg L-1. Hasil kuantitatif zat goniotalamin dengan Kromatografi Cair Prestasi Tinggi terdapat pada perlakuan 2,4-D 5,0 mgL-1 + BAP 1 mg L-1 yaitu 9,57 mg g-1.The goniothalamine compound on Goniothalamus tapis is an alternative cancer medicine. This study aimed to obtain gonotalamin through callus culture and suspension cell culture. The experiment research method was Completely Randomized Design (CRD) with a combination of 2.4-D (1-10 mg L-1) and BAP (0.5-2 mg L-1) using young stem explants consisting of 17 treatments with 3 replications. Data analysis used ANOVA and DMRT at 5%. The results showed that G. tapis callus culture on 5.0 mg L-1 2.4-D + 1 mg L-1 BAP was the best treatment medium with callus emergence time of 28.33 days and percentage of callus formation 100%. The callus used for suspension cell culture was friable and greenish-yellow in color. Suspension cell culture resulted in rapid cell growth, was not fleshy, and easily separated. The  quality test by Thin Layer Chromatography (TLC) from suspension cell culture resulted very clear, clean, and potential content of goniothalamin found in treatments 2.4-D 5.0 mg L-1 + BAP 0.5 mg L-1, 2.4-D 5.0 mg L-1 + BAP 1 mg L-1, 2.4-D 5.0 mg L-1 + BAP 2 mg L-1, 2.4-D 10 mg L-1 + BAP 0.5 mg-1 and 2.4-D 10 mg-1 + BAP 1 mg-1. The quantitative results of the best goniotalamine compounds in cell suspension cultures using High-Performance Liquid Chromatography (HPLC) on medium 2,4-D 5.0 mgL-1 + BAP 1 mg L-1 ie 9.57 g-1.

Availability of quality seeds in production of krisan (Chrysanthemum morifolium Ramat cv Dewi ratih) cultivation is still rare, therefore research on seed multiplication through tissue culture is needed. The media used in tissue culture is relatively expensive for home industry. This study aims to determine the respond of leaf and stem explants using foliar fertilizers (Growmore, Gandasil D and Mutiara) as an alternative media for callus inductions. This study used a Completely Randomized Design (CRD) consisted of 4 treatments: P0: ½ MS + 0,25 mg/l BAP, P1 (Growmore + 0,25 mg/l BAP), P2 (Gandasil D + 0,25 mg/l BAP), P3 (Mutiara + 0,25 mg/l BAP). The variables observed in this study included callus appearance time, callus color and callus texture. The result of this study indicated that the use of BAP (6-Benzyl Amino Purine) affected the time of callus formation and callus morphology. Callus was formed on leaf explants 13 days after planting while on stem explants 7 days after planting and compact texture. Growmore + 0,25 mg/l BAP treatment yields the best callus on leaf explant, while Gandasil D + 0,25 mg/l BAP treatment yields the best callus on stem explant.

Arabidopsis thaliana is one of the best studied plant model organisms. Besides cultivation in greenhouses, cells of this plant can also be propagated in suspension cell culture. At7 is one such cell line that was established about 25 years ago. Here, we report the sequencing and the analysis of the At7 genome. Large scale duplications and deletions compared to the Columbia-0 (Col-0) reference sequence were detected. The number of deletions exceeds the number of insertions, thus indicating that a haploid genome size reduction is ongoing. Patterns of small sequence variants differ from the ones observed between A. thaliana accessions, e.g., the number of single nucleotide variants matches the number of insertions/deletions. RNA-Seq analysis reveals that disrupted alleles are less frequent in the transcriptome than the native ones.

Poloxamers are water-soluble polymers that are widely used in cell culture bioprocessing to protect cells against shearing forces. Use of poor-quality poloxamers may lead to a drastic reduction in cell growth, viabilities and productivities in cell culture-based manufacturing. In order to evaluate poloxamer quality and promote more consistent performance, a rapid cell membrane adhesion to hydrocarbon assay was developed based on the adhesive properties of cell membranes to selective hydrocarbons. The assay can identify a poor-performing poloxamer characterized by significant drop in viable cell density and percent viability. The assay was verified across multiple good and bad poloxamer lots, and the results were in agreement with established cell growth and high-performance liquid chromatography assays.
