The Use of Nicotiana Species in Tobacco Improvement

  title={The Use of Nicotiana Species in Tobacco Improvement},
  author={Apoloniusz Berbe{\'c} and Teresa Doroszewska},
There are more than 80 naturally occurring relatives of cultivated tobacco (Nicotiana tabacum L.) in the genus Nicotiana. In this review, we examine how and to what extent these natural germplasm resources have been utilized in hybridization and introgression experiments over the past century. To date, more than 400 interspecific Nicotiana hybrids have been reported. We focus on individual Nicotiana species involved in interspecific hybrids with cultivated tobacco produced by sexual and asexual…

Polyploidy in Industrial Crops: Applications and Perspectives in Plant Breeding
Polyploidisation is used in plant breeding to overcome the non-viability and infertility of interspecific hybrids, obtain seedless polyploid cultivars and increase resistance/tolerance to biotic and abiotic factors.


Aspects of the evolution of Nicotiana tabacum L. and the status of the United States Nicotiana Germplasm Collection
Genetic variability within N. tabacum L., the species of primary economic importance, was likely affected by several genetic bottlenecks and resulted in the formation of narrow genetic pools corresponding to modern commercial market classes.
Hybrid fertility and aphid resistance in the cross Nicotiana tabacum x N. gossei
Nicotiana gossei, a disease- and insect-resistance species, was hybridized with the cigar-wrapper variety of N. tabacum, ‘Florida 17’, and converted to a fertile amphiploid by treatment with colchicine.
Wild Nicotiana Species as a Source of Cytoplasmic Male Sterility in Nicotianatabacum
Abstract The results of our experiments executed to obtain tobacco male sterile lines through interspecific hybridization are summarized. Ten wild species from the genus Nicotiana: N. excelsior
Fertile somatic hybrids between transgenicNicotiana tabacum and transgenicN. debneyi selected by dual-antibiotic resistance
A simple, yet effective selection system was used to produce fertile somatic hybrids between Nicotiana tabacum and N. debneyi, which differ from the malesterile tobacco ‘cybrids’ and alloplasmic lines produced by transferring theN.debneyi cytoplasm to tobacco.
Seven of eight species in Nicotiana section Suaveolentes have common factors leading to hybrid lethality in crosses with Nicotiana tabacum.
Hybrid lethality was observed in all crosses at 28 degrees C, and was Type II lethality, with the characteristic symptoms of browning of hypocotyl and roots, suggesting that many species of section Suaveolentes share the same factor that triggers hybrid lethality by interaction with the genes on the Q chromosome.
Q Chromosome Controls the Lethality of Interspecific Hybrids between Nicotiana tabacum and N. suaveolens
Results suggested that the Q chromosome of the S genome harbored a gene or genes that induced non-viable seedlings from a cross between N. tabacum and N. suaveolens, and revealed that 3 viable plants were true F1 hybrids.
Interspecific cross‐hybrids of Nicotiana tabacum L. cv. (gla.) S ‘K326’ with Nicotiana alata
In order to elucidate the unexpected fertility recovery of the fertile F1 plants, some N. alata fertility restoration ppr genes were cloned and were shown to be differentially expressed between parental lineages as well as between both F1 subgroups, suggesting that N. alata contains fertility restoring allele able to overcome the CMS of N.tabacum.

Transmission of paternal chloroplasts in tobacco (Nicotiana tabacum)
Tests of resistance of the seedlings to tentoxin and restriction analyses of the chloroplast DNA indicated that two clones still had the maternal chloroplasts and were thus probably new streptomycin-resistant mutants, whereas the third one had acquired the chloroplast of the paternal parent, but had retained the mitochondria of the maternal parent.
