Abstract

Cyanogenic glycosides are hydrocarbon compounds that can bind to CN groups and sugars. Certain plants, notably higher plants, can perform cyanogenesis, forming cyanogenic glycosides as by-products of biochemical reactions. From a medical perspective, cyanide is known to negatively impact health, particularly the respiratory system, as it binds oxygen in the blood to toxic compounds. Symptoms of cyanide poisoning from food consumption include dizziness, weakness, vomiting, throat inflammation, and abdominal cramps. Acute poisoning and death have been reported from consuming food containing 50 – 100 mg of cyanide. This review utilizes a literature study method, focusing on national journals from the past decade accessed via Google Scholar. The findings identify five plant species containing cyanogenic glycosides: cassava, bamboo shoots, cassava leaves, raw Pangium edule seeds, and Dioscorea hispida tubers. Cassava, in particular, contains linamarin, a cyanogenic glycoside found in all parts of the plant, with bitter varieties generally having higher toxin levels.

Abstract

Black stem potato (Solanum tuberosum L. var. cingkariang/cingkariang potato) are a specific germplasm of West Sumatra with low productivity. One method of propagating this plant is through tissue culture techniques. The addition of Plant Growth Regulator (PGR) determines the results of plant propagation through tissue culture technique. Cytokinins such as 6-Benzylaminopurine (BAP) play a role in cell division and accelerate shoot formation. This study expects to decide the impact of a few convergences of BAP on the shoot enlistment of cingkariang potato. The examination utilized a totally randomized plan (CRD) with four treatments (0, 1, 2, and 3 mg/L BAP) and six replications. The result showed that BAP was able to induce Cingkariang potato shoots in all concentration. BAP 2 mg/L gave the fastest shoot and root emergence time and also gave the highest number of shoots and roots of Cingkariang potato. BAP 2 mg/L was the best concentration for shoot induction of black stem potato (Solanum tuberosum L. var. Cingkariang).

Abstract

Biostimulants are natural compounds that can stimulate plant growth. Biostimulants from Padina minor contain secondary metabolites and growth-regulating substances needed in various plant growth metabolisms, including soybeans (Glycine max L.). Biostimulants also play a role in enhancing drought stress tolerance in plants. Several solvents are used to extract natural compounds found in P. minor. This study aims to investigate the effect of P. minor biostimulant extracted using various solvents on soybeans' chlorophyll content under different drought stress levels. The study used a completely randomized design (CRD) with two factors: a. Solvent (control, aquadest, methanol, and ethanol) and b. Soil field capacity (100%, 75%, 50%, and 25%). Applying P.minor as biostimulant extracted with methanol solvent showed higher average chlorophyll a, b, and total chlorophyll than other solvent types. Imposing stress up to 25% did not significantly affect soybean chlorophyll levels. However, the interaction between soil field capacity and P. minor extract from methanol solvent can trigger resilience response to drought conditions up to 25% soil field capacity and provide the highest average chlorophyll content compared to other treatments during the soybean vegetative period. Methanol is the best solvent for extracting P. minor as biostimulant and can provide the highest average chlorophyll content at 25% soil field capacity.

Abstract

Dendrobium mussaense, an orchid species of high ornamental value, was subjected to experimental treatments involving the addition of combinations of auxin and cytokinin, namely 2,4-D (2,4-dichlorophenoxyacetic acid) with BAP (6-benzylaminopurine) and 2,4-D with TDZ (thidiazuron). The research aim was to evaluate their effects on the emergence time of shoots and roots. The method used an experiment design with seven treatments. Among the treatments, the most effective was 2,4-D at a concentration of 1 mg/L combined with 0.75 mg/L of BAP. This treatment resulted in the shortest time for both shoot and root emergence. These findings underscore the importance of optimizing hormone combinations for efficient shoot and root induction in D. mussaense, providing valuable insights for orchid propagation and cultivation practices.

Abstract

Mesenchymal stem cells (MSCs) are a type of multipotent stem cells that can be found in various tissues of the body, possessing good regenerative qualities and promising immunomodulatory abilities for therapy in various medical conditions. MSCs can be obtained from bone marrow, umbilical cord, adipose tissue, and Warthon's jelly. This study aims to present a systematic review of the use of mesenchymal stem cells in disease therapy, by evaluating the latest evidence regarding their efficacy and safety in various therapies. This review uses literature review methods from international data bases such as PubMed and Google Scholar. The total number of articles obtained from the database was 49 articles. These articles were then filtered using inclusion and exclusion criteria, resulting in 22 articles for this systematic review. The research findings indicate that MSCs therapy has been used for the treatment of liver fibrosis, diabetes mellitus, spinal cord injury, and COVID-19. In MSCs therapy, mechanisms involved paracrine effects (MSCs produce cytokines, growth factors, and other proteins); immunomodulation (MSCs can suppress immune cell activation, inhibit lymphocyte proliferation, modulate natural killer T cell activation, and produce anti-inflammatory factors); angiogenesis (MSCs are capable of stimulating the growth of new blood vessels through secretion of VEGF and FGF); cellular differentiation; and anti-fibrotic effects. This is what makes MSCs potentially promising as an evolving alternative treatment.

Abstract

Soybean (Glycine max) is a primary food commodity for the people in Indonesia, with most of its needs still dependent on imports. Efforts to increase local production require a sustainable strategy, including by use biostimulants. Natural biostimulants, such as fern leaf extract, is proven to be a solution in increasing the growth of plants. This study aims to evaluate the potential use of fern leaf extract as a biostimulant on biomass and the number of root nodules in soybean plants. The method used in this study was a factorial complete randomized design with 2 factors and 3 replications. Factor A is the source of crude extract of fern leaves, control, Gleichenia linearis, Diplazium esculentum, Nephrolepis exaltata, and Blechnum orientale. Factor B is the frequency of application extracts, namely 1 time and 2 times.The results showed that the application of Diplazium esculentum leaf extract with one application significantly increased the total number of root nodules, the number of effective root nodules and vegetative phase biomass. While in Nephrolepis exaltata with one time application can significantly increase the number of total root nodules and the number of effective root nodules. This increase is indicated by the content of bioactive compounds contained in the extract, so that it can increase the growth of soybean plants by stimulating the activity of soil microorganisms.

Abstract

The Papuan indigenous plant Cryptocarya massoy (Oken) Kosterm has substantial commercial significance as an essential oil source. Plant growth regulators (PGRs) are essential for regulating growth responses including callus development, and tissue culture offers a viable means of reproducing this species. Kinetin, a cytokinin-type PGR, is particularly important in promoting cell division and callus development. This study aimed to evaluate the growth response of C. massoy explants under varying kinetin concentrations and determine the optimal concentration for callus induction. The experiment utilized a Completely Randomized Design (CRD) with three kinetin treatments: 0.5 mg/L (A), 1.0 mg/L (B), and 1.5 mg/L (C). Results showed that 1.0 mg/L kinetin achieved the highest explant survival rate (71%) and the lowest browning rate (8%), compared to 13% browning at 0.5 mg/L and 1.5 mg/L. However, the highest callus formation (0.25 average callus) with a compact, brownish texture was observed at 1.5 mg/L. The 0.5 mg/L concentration consistently exhibited the lowest response across all parameters. These findings indicate that 1.0 mg/L kinetin is optimal for enhancing explant survival and minimizing browning, while 1.5 mg/L is more effective for inducing callus formation, underscoring the importance of kinetin concentration in optimizing C. massoy tissue culture protocols.
