Optimization of Agrobacterium-mediated transformation procedure for an indica rice variety-Khang Dan 18
Tập 20 Số 1 - Trang 53-62 - 2022
In addition to traditional methods, advanced biotechnologies, especially CRISPR/Cas9-mediated genome editing, have emerged as effective tools for improving important agronomic traits in rice. However, the critical step for utilizing these systems is to develope an effective system for rice transformation and regeneration. This study was performed to establish procedures for Agrobacterium-mediated ......
The domestic wastewater treatment capacity of Spirulina platensis SP4 and the application of the treated wastewater in stimulating rice germination
Tập 20 Số 4 - Trang 773-784 - 2022
Many scientists are interested in microalgae and cyanobacteria because of their richness in high-value bioactive metabolites (proteins, lipids, vitamins, plant growth regulators, and others). Microalgae and cyanobacteria can be used to produce valuable commodities such as dietary supplements, biofuel, animal feed, and agricultural fertilizer, etc. To improve the economic feasibility of the cyanoba......
Effect of exogenous melatonin on antioxidant enzyme activities and membrane lipid peroxidation in avocado fruit during ripening
Tập 20 Số 3 - Trang 495-504 - 2024
Melatonin functions as a plant growth regulator, has diverse functions and plays an important role in ripening and fruit senescence. In the current study, we investigated the effect of exogenous melatonin (0.1 mM and 0.5 mM) on reactive oxygen species (ROS) metabolism, membrane lipid peroxidation and antioxidant enzyme activity of avocado (Persea americana Mill. cv. 034) during fruit ripening at 2......
In vitro safety evaluation of Bacillus subtilis species complex isolated from Vietnam and their additional beneficial properties
Tập 20 Số 4 - Trang 727-740 - 2022
Bacillus genus are Gram-positive, rod shaped, spore-forming, aerobic or facultative anaerobic bacteria, which have the ability to produce a wide variety of enzymes, antimicrobial compounds, vitamins, and carotenoids. Nowadays, Bacillus species have been increasingly proposed for use as probiotics or feed additives as B. amyloliquefaciens, B. licheniformis, B. subtilis, and B. pumilus because of th......
Production of in vitro strawberry (Fragaria × ananassa) plantlets in large-scale system supplemented with silver nanoparticles
Tập 19 Số 3 - Trang 481-493 - 2021
The growth of strawberry plantlets in the rooting stage on culture medium supplemented with silver nanoparticles (AgNPs) and the ethylene gas accumulation in plantlet culture bottles were investigated. In addition, different culture systems were first used to produce large-scale Strawberry plantlets. The results showed that shoots (3 cm) were cultured on MS medium supplemented with 0.02 mg/L NAA, ......

The roles of microalgae and bacteria in wastewater treatment
Tập 20 Số 3 - Trang 573-588 - 2024
Nature-based wastewater treatment employing microalgae and bacteria has gained serious attention due to its combination with valuable biomass production. In wastewater, microalgae serves as the primary source of dissolved oxygen (DO) production for bacterial organic matter degradation. In addition, microalgae can effectively remove nutrients, pathogens as well as various heavy metals. Bacteria, on......
Effects of nanoparticles zinc oxide and nano cobalt on the germination of soybean (Glycine max (L.) Merr)
Tập 16 Số 3 - Trang 501-508 - 2018
Nowaday, nanotechnology and nanomaterials have been applied widely as stimulars and micronutrions in agricultural production to increase productivity and quality of important crops. In order to promote the efficiency and stable use of nano metal products for such purpose in Vietnam, several studies have focused on evaluating new metal nanoparticles in different plant species. In this study, the ef......

Effects of simulated microgravity on seed germination, growth, development and accumulated secondary compounds of Hibiscus sagittifolius Kurz. cultured in vitro
Tập 15 Số 1 - Trang 73-85 - 2017
In the present study, Hibiscus sagittifolius Kurz. seeds were used as the plant materials for studying on the effects of simulated microgravity (on a 2D clinostat) on seed germination, shoot multiplication, growth, development and secondary metabolite accumulation. After surface sterilization, seeds were cultured on MS medium supplemeted with 30 g/l sucrose and 9 g/l agar in Petri dishes (9 seeds ......

Diversity of endophytic fungi from medicinal plants Dysosma difformis (Hemsl & E.H. Wilson) T.H. Wang collected in Ha Giang and Lai Chau
Tập 21 Số 2 - Trang 365-373 - 2023
Plant endophytes are an interesting group of microorganisms that colonize the internal tissues of living plants and do not cause any disease symptoms in the host plant. It exists in different parts of plants, such as roots, leaves, and stems, and significantly affects the formation of metabolic products in plants by promoting the accumulation of important secondary metabolites. The present study f......
