Development of a potent in vitro source of Phyllanthus amarus roots with pronounced activity against surface antigen of the hepatitis B virus
(C A B I PUBLISHING, 2004-09)In vitro culture of hairy roots of Phyllanthus amarus induced by Agrobacterium rhizogenes was established. Their growth and ability for in vitro inactivation of hepatitis B virus surface antigen was studied and compared ... -
Conservation and documentation of the medicinal plant resources of India
(SPRINGER, 2006-07)In India, activities in the field of medicinal plants, including conservation of germplasm, have been enhanced significantly during the past couple of decades and a huge volume of data is being generated out of these works. ... -
In vitro conservation of Plumbago indica - A rare medicinal plant
(Society for Biology and Biotechnology, 2007-03)Present work has been conducted on in vitro conservation of a rare medicinal plant, Plumbago indica, through storage of germplasms derived from micropropagated progenies of the species. Direct regeneration of axillary ... -
An improved micropropagation of Eclipta alba by in vitro priming with chlorocholine chloride
(SPRINGER, 2008-03)An efficient method of micropropagation for Eclipta alba from young nodal axils of shoot tip explants has been developed by giving special attention to 'priming' in vitro plantlets in view of increasing their hardening ... -
Cryopreservation of in vitro grown nodal segments of Rauvolfia serpentina by PVS2 vitrification
(CRYO LETTERS, 2008-07)This paper describes the cryopreservation by PVS2 vitrification of Rauvolfia serpentina (L.) Benth ex kurz, an important tropical medicinal plant. The effects of type and size of explants, sucrose preculture (duration and ... -
Storage and plant regeneration from encapsulated shoot tips of Rauvolfia serpentina - An effective way of conservation and mass propagation
(ELSEVIER, 2008-11)Encapsulated shoot tips of Rauvolfia serpentina were stored at 3 different temperatures (20 degrees C, 12 degrees C and 4 degrees C). Synseeds converted randomly after 4 weeks of storage at 12 degrees C and 20 degrees C. ... -
Clinico-Immunochemical Studies on Airborne Areca catechu L. Pollen, a Probable Risk Factor in Emergency Asthma Hospitalization from Eastern India
(KARGER, 2009-07)Background: The pollen grain of the Areca catechu L. tree is airborne and allergenic. This study aimed to know the role of this pollen as a source of aeroallergen with effect on emergency asthma hospitalization, to isolate ... -
Hairy root culture of Plumbago indica as a potential source for plumbagin
(SPRINGER, 2008-09)Hairy roots of Plumbago indica were established at high frequency ( 90 %) by infecting leaf explants with Agrobacterium rhizogenes strain ATCC 15834. The axenic root cultures were established under darkness in hormone-free ... -
In Vitro propagation of Jasminum officinale L.: a woody ornamental vine yielding aromatic oil from flowers
(SPRINGER, 2010)The growing demand for flower extracts in perfume trade can primarily be met by increasing flower production and multiplying planting material. The major commercial aromatic flower yielding plants including Jasminum ... -
Storage and conversion of Eclipta alba synseeds and RAPD analysis of the converted plantlets
(SPRINGER, 2010-09)The encapsulated shoot tips and nodal segments of Eclipta alba were stored at 4, 12 and 20 °C under irradiance of 1.5 μmol m-2 s-1 and high conversion was observed in synseeds stored at 4 °C for 8 weeks. Duration of storage ... -
Encapsulation and Regeneration of in vitro Derived Zephyranthes grandiflora: an Effective Way for Exchange of Germplasm
(NATURAL PRODUCTS, 2010-08)An attempt was made to develop a protocol for the preparation of synthetic seeds using in vitro regenerated, genetically identical bulbs of Zephyranthes grandiflora. Encapsulation was standardized with 4% sodium alginate ... -
Effect of Different Strains of Agrobacterium rhizogenes and Nature of Explants on Plumbago indica Hairy Root Culture with Special Emphasis on Root Biomass and Plumbagin Production
(NATURAL PRODUCTS INC, 2010-12)The aim of the present study was to determine the effect of three strains of Agrobacterium rhizogenes (ATCC 15834, A(4) and LBA 9402) and the nature of explants (leaf and stem) on hairy root induction, growth and plumbagin ... -
Clonal propagation of Zephyranthes grandiflora using bulbs as explants
(SPRINGER, 2010-12)Zephyr lily (Zephyranthes grandiflora), an important ornamental plant has been micropropagated in vitro after controlling microbial contamination by a pretreatment with 0.2 % Bavistin and 0.1 % Pantomycin for 4 h before ... -
Regeneration of transformed plants from hairy roots of Plumbago indica
(SPRINGER, 2010-07)Spontaneous shoot regeneration was observed from Agrobacterium rhizogenes-induced hairy roots of Plumbago indica when these were incubated in liquid MS medium for a period of 3 weeks under continuous light. Insertion of ...
