Pollen germination and pollen tube growth have been used as end points. Pollen grains from a number of plants have been used, and an assay for growth of pollen from Nicotiana sylvestris has been developed (Kristen and Kappler 1995).

The overall goal of the TGI is to sequence and annotate more than 90% of the open reading frames in the genome of cultivated tobacco, Nicotiana tabacum. Nicotiana tabacum is an amphiploid species (2n = 48) likely resulting from an interspecific cross between Nicotiana sylvestris (2n = 24) and Nicotiana tomentosiformis (2n = 24), and at approximately...

From the available data it can be tentatively concluded that the level and/or metabolism of endogenous cytokinins changes markedly, often transiently, at the time of floral transition in many plant species [1]. The trend of changes was, however, opposite in species with different photoperiodic requirements an increase in levels was recorded, for example, in leaves of the LDP Hyoscyamus and Nicotiana sylvestris and the SDP Begonia, whereas a decrease was observed in the SDP Xanthium and Chenopodium [see 5, 11, 16].

When we studied the compositional distribution of six genes (or small multigene families) and one family of transposable elements, Tntl, in DNA fractions from tobacco Nicotiana tabacum) separated according to base composition, we could show that gene distribution is bimodal and that such bimodality is due to the different base composition of the two parental genomes of tobacco N. sylvestris and N. tomentosiformis) and to the different parental origin of the genes tested (Matassi et al., 1991).
