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 کاملComparison of protein profiles and enzymes in non-mycorrhizal and mycorrhizal roots of Pennisetum pedicellatum.
Pennisetum pedicellatum plants were inoculated with Glomus mosseae, G. aggregatum and Gigaspora margarita. There were both quantitative and qualitative changes in the protein pattern of inoculated plants. Gi. margarita induced increase in protein in the plants. Acid phosphatase, alkaline phosphatase, superoxide dismutase and chitinase activities were high at the beginning of infection, but decl...
متن کاملResistance to Striga hermonthica in Wild Accessions of the Primary Gene Pool of Pennisetum glaucum.
ABSTRACT Resistance to Striga hermonthica in 274 wild Pennisetum glaucum subsp. monodii and stenostachyum accessions was evaluated at Samanko, Mali in 1997 and 1998, and at Cinzana, Mali and Sadoré, Niger in 1998. Data recorded included number of striga plants per plot at least three times during the season, date of striga emergence, number of Pennisetum plants, Pennisetum anthesis date, and do...
متن کاملCytological investigations and new chromosome number reports in yarrow (Achillea millefolium Linnaeus, 1753) accessions from Iran
In this study, a new chromosome number for Iranian yarrow (Achillea millefolium L.) accessions was reported. Cytological analyses on four Achillea millefolium accessions, indicated that two accessions were diploids (2n=2x=18) and two tetraploids (2n=4x=36). Cluster analysis based on chromosomal characteristics and karyotype asymmetry, categorized the four accessions separated into two groups. I...
متن کاملGenomic homeology between Pennisetum purpureum and Pennisetum glaucum (Poaceae)
The genus Pennisetum (Richard, 1805) includes two economically important tropical forage plants: Pennisetum purpureum (Schumacher, 1827) (elephant grass), with 2n = 4x = 28 chromosomes and genomes A'A'BB, and Pennisetum glaucum (Linnaeus, 1753) (pearl millet), with 2n = 2x = 14 chromosomes and genomes AA. The genetic proximity between them allows hybrids to be obtained (2n = 3x = 21) that yield...
