Micropropagation of Tectona grandis: assessment of genetic fidelity
(KLUWER ACADEMIC PUBL, 2003)Random amplified polymorphic DNA (RAPD) markers were used to analyze genetic fidelity of micropropagated teak (Tectona grandis L.) clones with respect to subcultural passage. Of the twenty primers screened, no variation ... -
Agrobacterium-mediated genetic transformation in Indian spinach (Beta palonga)
(ELSEVIER, 2003-09)An efficient and reproducible protocol for Agrobacterium-mediated plant transformation has been standardized in Indian spinach (Beta palonga) with a standard vector (pCambia 1304). Passage wise subculture in medium containing ... -
Luffa sponge - a unique matrix for tissue culture of Philodendron
(CURRENT SCIENCE ASSN, 2004-01-25)An efficient and simple micropropagation protocol of Philodendron 'Xanadu', highly esteemed for its beautiful foliage, has been established. Rapid multiplication was attained by high concentration of N-6-benzyladenine, but ... -
Trichomes: their diversity, distribution and density in acclimatization of teak (Tectona grandis L.) plants grown in vitro
(KLUWER ACADEMIC PUBL, 2004-08)Diversity, distribution and density of trichomes were studied in relation to other morphological and physiological parameters of in vivo and in vitro teak (Tectona grandis L.) plants with the objective to understand their ... -
Micropropagation of Indian pandan (Pandanus amaryllifolius Roxb.), a rich source of 2-acetyl-1-pyrroline
(CURRENT SCIENCE ASSN, 2004-11-10)protocol for clonal propagation of Pandanus amary-llifolius, a rich source of 2-acetyl-1-pyrroline (2AP), an aromatic compound, has been established. Genetic fidelity of the tissue-culture-raised plantlets was ascertained ... -
Nypa fruticans of Sundarban Biosphere Reserve, West Bengal, India - Its genetic diversity and an approach for conservation
(International Society of Plant Morphologists., 2005-01)Sundarban Biosphere Reserve of India is a UN declared Natural Heritage. It is a wetland with unique mangrove vegetation. Nypa fruticans (Thunb.) Wurmb. (Arecaceae) is one of the threatened mangrove palms of this region. ... -
Encapsulation of pineapple micro shoots in alginate beads for temporary storage
(CURRENT SCIENCE ASSN, 2005-03-25)Micro shoots developed from the meristematic basal portion of the innermost leaves of pineapple [Ananus comosus (L.) Merr] were encapsulated in alginate beads for short-term storage as a prelude to the transformation ... -
Enhancement of in vitro micro corm production in Gladiolus using alternative matrix
(ACADEMIC JOURNALS, 2006-06-16)An efficient in vitro protocol for mass propagation of Gladiolus was developed. Basal portions of the innermost leaves responded readily in culture. Ten to fifteen adventitious shoot buds emerged from every responding ... -
Sex detection of Carica papaya and Cycas circinalis in pre-flowering stage by ISSR and RAPD
(CURRENT SCIENCE ASSN, 2007-02-25)The sex of Carica papaya, an angiosperm and Cycas circinalis, a gymnosperm was studied using ISSR and RAPD techniques in pre-flowering stage. One female-specific band generated from ISSR profile using primer (GACA)(4) was ... -
Assessment of genomic diversity of wild and cultivated tomato through resistance gene analogue polymorphism and I2 homologues
(SPRINGER, 2007-03)Plant disease resistance gene analogue polymorphism (RGAP) in tomato has been studied on the basis of NBS-LRR (Nucleotide Binding Site-Leucine Rich Repeat) class of genes using degenerated primers. Results revealed variable ... -
A cDNA-AFLP approach to look for differentially expressed gene fragments in dioecious pointed gourd (Trichosanthes dioica Roxb.) for understanding sex expression
(CURRENT SCIENCE ASSO, 2008-02-10)Transcript profiling of unopened male and female floral buds of pointed gourd (Trichosanthes dioica Roxb.), a dioecious cucurbit, at uniform developmental stage was done through eDNA-AFLP to look for the differentially ... -
Agrobacterium-mediated genetic transformation of pineapple var. Queen using a novel encapsulation-based antibiotic selection technique
(SPRINGER, 2009-06)A protocol for Agrobacterium-mediated transformation of a local 'elite' Indian variety (Queen) of pineapple [Ananus comosus (L.) Merr, family Bromeliaceae] has been established using a standard transformation vector (pCAMBIA ... -
Plant response to alternative matrices for in vitro root induction
(ACADEMIC JOURNALS, 2009-07-06)The quest for alternative matrices for plant tissue culture is a continuing process. This inquiry has two aspects. One being commercial for low cost tissue culture, and the other obviously is the better root induction ... -
Is stem twining form of Basella alba L. a naturally occurring variant?
(INDIAN ACAD SCIENCES, 2010-05-25)A naturally occurring circumnutating stem form of Basella alba L. has been characterized in the background of two procumbent stem forms of B. alba L., cultivated commonly as leaf vegetable. The difference between the ...
