Immunocytochemical localization of saikosaponin-d in vegetative organs of Bupleurum scorzonerifolium Willd
Botanical Studies - Tập 54 - Trang 1-8 - 2013
Saikosaponin-d (SSd) is an important active component of Bupleurum
scorzonerifolium Willd., a traditional Chinese medicinal herb. Thus far, the
biosynthetic pathway and biosynthetic site of saikosaponins in Bupleurum are
largely unknown. The cellular localization of SSd will help in understanding
saikosaponin biosynthesis and regulation. In this study, we characterize for the
first time the locali...
Six new species of Begonia from Guangxi, China
Botanical Studies - Tập 61 - Trang 1-23 - 2020
With currently 1980 described species, the mega-diverse Begonia is now perhaps
the 5th largest flowering plant genus, expanding rapidly from ca. 900 species in
1997 to its current size in merely two decades. In continuation of our studies
of Asian Begonia, we report six additional new species from Guangxi, the
region/province harboring the second richest Begonia flora of China. Based on
morphologi...
The seasonal variations of allelopathic activity and allelopathic substances in Brachiaria brizantha
Botanical Studies - Tập 56 - Trang 1-7 - 2015
Controlling weeds through allelopathy is one strategy to reduce dependency on
synthetic herbicides. The plant shoots of the grass Brachiaria brizantha
incorporated into the field soil were found to inhibit the growth of several
plant species. We investigated the variations of allelopathic activity and
allelopathic substances in B. brizantha harvested in June, October and January.
All extracts of B...
Impatiens pandurata (Balsaminaceae), a new species from Yunnan, China
Botanical Studies - Tập 56 - Trang 1-6 - 2015
The species-rich genus Impatiens is mainly distributed throughout much of
tropical Africa, India, southwest Asia, southern China and Japan. There are more
than 270 species recorded in China, most of which are restricted to the
southwest. An unknown species of Impatiens was collected from Yunnan, southwest
China. Impatiens pandurata Y. H. Tan & S. X. Yu, a new species of Balsaminaceae
from Jinping ...
Enhanced synthesis of andrographolide by Aspergillus niger and Penicillium expansum elicitors in cell suspension culture of Andrographis paniculata (Burm. f.) Nees
Botanical Studies - Tập 54 - Trang 1-8 - 2013
Andrographis paniculata (Burm. f.) Nees is an important medicinal plant which
has enormous applications in pharmaceutical industries. Cell suspension culture
of Andrographis paniculata (Burm. f.) Nees. was treated with Aspergillus niger
and Penicillium expansum elicitors to enhance the synthesis of andrographolide,
the bioactive constituent of A. paniculata. The elicitation treatment with
fungal e...
Study on the effect of magnetic field treatment of newly isolated Paenibacillus sp.
Botanical Studies - Tập 56 Số 1 - 2015
Abstract Background Symbiotic nitrogen fixation in plants occurs in roots with
the help of some bacteria which help in soil nitrogen fertility management.
Isolation of significant environment friendly bacteria for nitrogen fixation is
very important to enhance yield in plants. Results In this study effect of
different magnetic field intensity and treatment time was studied on the
morphology, physi...
Cys-SH dựa trên proteomics redox định lượng về phản ứng do muối gây ra ở dòng bổ sung monosomic đường phiến M14 Dịch bởi AI
Botanical Studies - Tập 62 Số 1 - Trang 1-18 - 2021
Căng thẳng do muối là một loại căng thẳng môi trường phi sinh học chính hạn chế
sự phát triển, phát triển và năng suất của cây trồng. Nghiên cứu các cơ chế phân
tử của tính chịu đựng căng thẳng do muối có thể giúp nâng cao năng suất cây
trồng. Dòng bổ sung monosomic M14 của cây đường phiến thể hiện tính chịu đựng
với căng thẳng do muối. Trong công trình này, sự thay đổi trong proteome BvM14
và pro...

Current state of populations of Rhodiola rosea L. (Crassulaceae) in East Kazakhstan
Botanical Studies - Tập 62 - Trang 1-20 - 2021
Based on world experience, first, a modern assessment of the flora is needed to
develop strategies for the conservation of ecosystems of rare and endangered
plant species. A regional and global biodiversity strategy should focus on
assessing the current state of bioresources. To preserve the biodiversity of the
species and its habitat, we evaluated botanical features, ontogenetic phases,
the ecolo...
Exogenous hydrogen peroxide increases dry matter production, mineral content and level of osmotic solutes in young maize leaves and alleviates deleterious effects of copper stress
Botanical Studies - Tập 54 - Trang 1-10 - 2013
The effects of exogenously applied H2O2 on growth, water status, the mineral ion
content (Na+, K+, Ca2+, Mg2+ and Cu2+), proline, total sugars and soluble
proteins were assessed in leaves of maize (Zea mays L.) cultivars, Akpinar and
Pegaso exposed to excess copper (0.5 mM). Seedlings were grown in equal-sizes
plastic pots and irrigated with Hoagland nutrient solution containing H2O2
or/and copper...
