Penetration and development of juveniles of tobacco cyst nematode (Globodera tabacum solanacearum) on a resistant (NC567) and a susceptible (K326) cultivar of flue-cured tobacco (Nicotiana tabacum L.) were determined in root zone chamber experiments. More vermiform juveniles developed into a swollen shape at 22, 27, and 31 degrees C than at 17 degrees C. Development of flask-shaped nematodes ap...
EVERAL workers have already reported that hybridization between Nicotiana species can bring about chromosome instability. One conspicuous case is loss of somatic plumbaginifolia chromosomes in derivatives of N . tabacum X N . plumbaginifolia hybrids (MOAV 1961). The present paper deals with another peculiarity of alien chromosomes in tobacco hybrid derivatives. It reports on heritable changes i...
The life cycles of the seed bugs, Kleidocerys punctatus Distant and Kleidocerys virescens F. (Hemiptera: Lygaeidae: Ischnorhynchinae), are reported for the first time. Description of all immature stages and adults are included. Adults and nymphs of K. punctatus are associated with several species of Alnus (Betulaceae), while those of K. virescens are associated with Nicotiana glauca Graham, Nic...
the genetic diversity of 40 tobacco (nicotiana tabacum l.) cultivars was analyzed using 12 issr primers. thecultivars were evaluated for 14 traits using a simple lattice design (7×7) with two replications. of 149 amplified bands, 142 (95.3%) were polymorphic. maximum and minimum bands were generated by primers ubc825 (17 bands and 94.11% polymorphic) and ubc824 (7 bands and 100% polymorphic), r...
Mounting evidence is merging to affirm the effectiveness of bacterial lipopolysaccharides (LPS) as biological control agents, inducers of innate immunity, and to stimulate/potentiate the development of defense responses in plants through protein phosphorylation-mediated signal perception/transduction responses. In vivo labeling of protein phosphorylation events during signal transduction indica...
