(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. ... -
A dideoxynucleotide-sensitive DNA polymerase activity characterized from endoreduplicating cells of mungbean (Vigna radiata L.) during ontogeny of cotyledons
(BLACKWELL PUBLISHING, 2007-04)Within this work we describe the purification and biochemical characterization of a ddNTP-sensitive DNA polymerase purified from mungbean (Vigna radiata cv B1, L.) seeds at 18 days after fertilization, when > 70% of the ... -
An ABRE-binding factor, OSBZ8, is highly expressed in salt tolerant cultivars than in salt sensitive cultivars of indica rice
(BIOMED CENTRAL LTD, 2006-08-30)Background: The bZIP class Abscisic acid Responsive Element (ABRE)-binding factor, OSBZ8 (38.5 kD) has been considered to regulate ABA-mediated transcription in the suspension cultured cells of japonica rice. Still, nothing ... -
Ultrastuctural dimorphism of micropyle determines differential germinability of Sesbania cannabina seeds
(ISTA-INT SEED TESTING ASSOC, 2006)S. cannabina seeds, obtained from a naturally occurring single population contained both dormant and non-dormant seeds. The water uptake pattern indicated that non-dormant seeds absorbed sufficient water to allow them to ... -
Isolation of low erucic acid-containing genotype of Indian mustard (Brassica juncea Czern. and Coss.) through F-1 hybrid anther culture
(ACADEMIC JOURNALS, 2006-11-16)Reciprocal crosses were done between two cultivars; cv. RJ15 and cv. RLM198 of Indian mustard ( Brassica juncea). Anther derived lines designated as A(1) plants, were raised through anther culture from these F-1 hybrid ... -
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 ... -
Air-borne viable, non-viable, and allergenic fungi in a rural agricultural area of India: a 2-year study at five outdoor sampling stations
