Assessment of genetic diversity in accessions of pearl millet (Pennisetum glaucum) and napier grass (Pennisetum purpureum) using microsatellite (ISSR) markers
Pearl millet (Pennisetum glaucum (L.) R. Br.) and napier grass (Pennisetum purpureum Schumach) are the most economically important species in the genus Pennisetum. Knowledge of genetic diversity of these two species would enhance their potentials for utilization. The present work assessed the genetic diversity and phylogenetic relationship among Nigerian and Indian accessions of pearl millet an...
متن کاملPlasmon Mutations in Cytoplasmic Male-Sterile Pearl Millet, PENNISETUM TYPHOIDES.
Spontaneous mutations from sterile to fertile were demonstrated in four different cytoplasmic male-sterile stocks of pearl millet. One stock, ASM-3, was of African origin, and the other three, LMS-1A, ASM-5, and ASM-7, all had the same cyptoplasm of Indian origin, but differed in nuclear make-up. These reversions were shown to be plasmon mutations, rather than genic in nature. ASM-3 mutated at ...
متن کاملOccurrence and Exposure Assessment of Aflatoxin B1 and Ochratoxin A in Pearl Millet (Pennisetum glaucum L.) from Tunisia
Background: Ochratoxin A (OTA) and Aflatoxin B1 (AFB1) are toxic secondary metabolites produced by certain mold species. In this primarily survey, we examined the OTA and AFB1 contamination of pearl millet grains distributed in Tunisia. Methods: Twenty-five pearl millet (Pennisetum glaucum L.) samples from different regions of Tunisia were analyzed by High Performance Liquid Chromatography co...
متن کاملIn vitro digestibility and amino acid composition of pearl millet (Pennisetum typhoides) and other cereals.
The purpose of this study was to compare in vitro digestibility, protein distribution patterns, and amino acid composition of pearl millet with other major cereals. Digestibility values for the pearl millet varieties were higher than that of sorghum and comparable to that of maize. In contrast to sorghum, digestibility of pearl millet and maize did not decrease significantly upon cooking. Prote...
متن کاملExtensive variation in chromosome number and genome size in sexual and parthenogenetic species of the jumping-bristletail genus Machilis (Archaeognatha)
Parthenogenesis in animals is often associated with polyploidy and restriction to extreme habitats or recently deglaciated areas. It has been hypothesized that benefits conferred by asexual reproduction and polyploidy are essential for colonizing these habitats. However, while evolutionary routes to parthenogenesis are manifold, study systems including polyploids are scarce in arthropods. The j...
