The genus Drimia (syn. Urginea), commonly called squill, represents a species complex, infrageneric delimitation being ill-defined due to morphological variability, population variation within species and polyploidy. In the present study, fluorescent chromosome banding and measurements of nuclear DNA content by flow cytometry were performed in five Indian(More)
The family Hyacinthaceae constitutes about 900 species of bulbous geophytes usually characterized by high mucilage content. Taxonomic delimitation of Hyacinthaceae has been controversial since the time of Linnaeus due to the absence of reliable discriminating characters. Pattern of genome size variation can thus be considered as an added character to aid(More)
Chromosome characters of three indigenous medicinal plants of high repute were studied. Their karyotypes were commonly mono-modal, decreasing in length from the longest to the shortest chromosomes. The chromosome complement in centromeric positions was 6sm+34M+24m for Bacopa monnieri (L.) Wettst. (2n = 64), for Tylophora indica (Burm.f.)(More)
Anthracnose caused by Colletotrichum gloeosporioides is an economically important disease which affects greater yam (Dioscorea alata L.) worldwide. Apart from airborne conidia, the pathogen propagules surviving in soil and planting material are the major sources of inoculum. A nested PCR assay has been developed for specific detection of C. gloeosporioides(More)
Determination of chromosome number and their analysis particularly in vast number of economically important medicinal tree species are far from complete. Chromosome analysis provides information on chromosomal behaviour and identifies the plant with a particular karyotype formula which is the basis of genome analysis in a particular species. The present(More)
