Genetic Variation in Picea mariana × P. rubens Hybrid Populations Assessed with ISSR and RAPD Markers

Detection of genetic variation in Ocimum species using RAPD and ISSR markers

There is a lack of information on the molecular characterization of Ocimum species and hence, efforts have been made under the present study to characterize 17 Ocimum genotypes belonging to 5 different species (O. basilicum, O. americanum, O. sanctum, O. gratissimum and O. Polystachyon) through random amplified polymorphic DNA (RAPD) and inter simple sequence repeats (ISSR) markers. PCR amplifi...

Negative heterosis not apparent in 22-year-old hybrids of Picea mariana and Picea rubens

Work from the 1970s indicated that, relative to either parent species, crosses between red spruce (Picea rubens Sarg.) and black spruce (Picea mariana (Mill.) B.S.P.) were inferior with respect to both growth and photosynthesis. We re-examined the hypothesis that there is negative heterosis in hybrids of red and black spruce using 22-year-old trees in a common garden study planted on two sites....

Genetic analysis of Morus alba through RAPD and ISSR markers

Information on the genetic identity and interrelationships of different Morus spp. genotypes is essential for their proper conservation and utilization. Hence, the present investigation was undertaken with genetically more reliable DNA markers to study the genetic relationship among eleven selected genotypes of mulberry collected from Japan, India and Italy. Using ten RAPD and ten ISSR primers,...

Genetic variation and control of chloroplast pigment content in Picea rubens, Picea mariana, and their hybrids, under ambient and elevated CO2 environments

Genetic variation and control of chloroplast pigment concentrations in Picea rubens, Picea mariana and their hybrids. I. Ambient and elevated [CO2] environments.

Traits related to light-energy processing have significant ecological implications for plant fitness. We studied the effects of elevated atmospheric CO(2) concentration ([CO(2)]) on chloroplast pigment traits of a red spruce (RS) (Picea rubens Sarg.)-black spruce (BS) (P. mariana (Mill.) B.S.P.) genetic complex in two experiments: (1) a comparative species' provenance experiment from across the...
