Silver nanoparticles enhanced efficiency of explant surface disinfection and somatic embryogenesis in Begonia tuberous via thin cell layer culture
Tập 19 Số 2 - 2021
Hoang Thanh Tung, Hoang Khai
In vitro culture establishment is one of the most important stages in
micropropagation. The disinfectant effectiveness depends on the type of surface
disinfectant, concentration and the time treatment. In this initial study,
silver nanoparticles (AgNPs) were used as a disinfectant for petioles, flower
stalks and stems of Begonia tuberous. In addition, thin cell layer culture (TCL)
technique has be... hiện toàn bộ

" Panax vietnamensis Ha et Gmshv., a rare Panax genus of Vietnam, is a well
known Vietnamese ginseng (Ngoc Linh Ginseng) for its rich pharmaceutical
compositions, most importantly saponin. In order to obtain a stable and
saponin-rich biomass of P. vietnamensis, a tissue culture procedure was
established. A TLC analysis of saponin composition was also conducted to
investigate the presence of saponi... hiện toàn bộ

DT Tham, HYN Bing, NTT Hang, D Van Khiem, N Van Duy, TT Vinh
Dendrobium heterocarpum Lindl. is an endangered species which is currently used
as ornamental pot plant for its beautiful flowers. An increase in collection for
trade or any other purposes may lead to a dramatic decrease in the population of
this species, thus becoming rare or endangered species in the near future. In
this study, effects of plant growth regulators (BA, NAA, IAA, IBA, TDZ) and

Genetic diversity plays an important role in diversity conservation at multiple
levels and supports to monitor and assess genetic variation. In plants, genetic
diversity provides the ability to adapt and respond to environmental conditions
that helps plants to survive through changing environments. Genetic diversity
analyses based on molecular genetic markers are effective tools for conservation

Identification of species based on DNA sequences (DNA barcodes) is an aid to a
taxonomic classification using morphological characteristics. DNA barcoding uses
standard short genomic regions that are universally present in target lineages
and has sufficient sequence variation to identify species in the genus. A
variety of loci has been suggested as DNA barcodes for plants, including genes
and non-... hiện toàn bộ

Honeybee products as potential bioindicators of heavy metals contamination from Northern Vietnam
Tập 18 Số 2 - 2020
Tran Thi Ngat
Contamination of heavy metals (As, Cd, Hg, Pb and Sn) in honeybee products (Apis
cerana) from Northern Vietnam is determined. The study was carried out in two
main harvesting seasons of beekeeper farms (April and October), over two years
(2018-2019). A total of 72 samples from 24 honeybee hives from 8 provinces and
one city were collected. The results showed that the quality of three products

Prodigiosin purification from Serratia marcescens M10 and its antitumor activities
Tập 19 Số 2 - 2021
VT Luong, NS Le Thanh
Prodigiosin (Pg) is a bright red pigment, which is produced by gram negative and
gram positive bacteria including Serratia marcescens, Hahella chejuensis, Vibrio
psychroerythrus, Streptomyces coelicolor and many other marine bacteria such as
Pseudomonas sp., Vibrio sp. Pg induces apoptosis in different kinds of cancer
cells with low toxicity on normal cells. In this study, we purified Pg from

Surface sterilization is one of the most important steps in preparation of
explants for micropropagation, because microbial contaminations present a major
challenge to the initiation and maintenance of viable in vitro cultures. Most of
popular surface disinfectants are considered as highly toxic influence either
directly or indirectly to health and environment. Previous studies have
demonstrated t... hiện toàn bộ
