“…Extensive empirical studies of interspecific hybridization of C. tinctorius with its wild relatives enable estimates of cross compatibility, provide information to predict potential hybridization and have been used to infer phylogenetic relationships within Carthamus (Kadam and Patankar 1942;Claassen 1950;Deshpande 1952;Ashri and Knowles 1960;Ashri and Efron 1964;Knowles and Schank 1964;Ashri and Rudich 1965;Knowles 1969Knowles , 1980Imrie and Knowles 1970;Khidir and Knowles 1970a, b;Imrie and Knowles 1971;Estilai andKnowles 1976, 1978;Estilai 1977;Heaton and Klisiewicz 1981;Kumar 1991;Jambhale 1994).…”

“…C. flavescens), C. palaestinus and C. oxyacanthus as separate species, but they are more likely races of a biological species (Table 1; Ashri and Efron 1964;Baker 1970;Imrie and Knowles 1970). The section Carthamus sensu López-González (1989) includes the four aforementioned species and both C. curdicus and C. gypsicola (Table 1).…”

“…The section Carthamus sensu López-González (1989) includes the four aforementioned species and both C. curdicus and C. gypsicola (Table 1). They share a chromosome number of n = 12 (Deshpande 1952;Ashri and Knowles 1960;Knowles 1989) and have been inferred as close relatives in phylogenetic studies utilizing data from morphology, cytogenetics and DNA sequences (Deshpande 1952;Ashri and Rudich 1965;Imrie and Knowles 1970;Knowles 1989;Vilatersana et al 2000). Most species of section Carthamus (Table 1) have been artificially crossed to produce fertile F 1 and F 2 progeny (Figs.…”

“…Hybridization with C. tinctorius and several wild relatives has been demonstrated to occur artificially (hand pollination; Kadam and Patankar 1942;Claassen 1950;Ashri and Knowles 1960;Ashri and Efron 1964;Imrie and Knowles 1970;Khidir and Knowles 1970a, b;Estilai andKnowles 1976, 1978;Estilai 1977;Heaton and Klisiewicz 1981) and naturally (open pollination; Kadam and Patankar 1942;Claassen 1950;Ashri and Rudich 1965). However, cross-compatibility of species, while relatively easy to measure, is not by itself a sufficient predictor of gene flow potential under field conditions.…”

safflower) is being evaluated as a crop for the production of plant-made pharmaceuticals using an oleosin fusion protein system. We evaluated the potential for transgenic gene flow from C. tinctorius to wild or weedy relatives in western Canada. Cytogenetic and phylogenetic studies with most of the species of Carthamus have demonstrated that cultivated C. tinctorius has the ability to hybridize with at least six wild or weedy relatives worldwide. Of the four naturalized wild relatives in the New World, only two, C. oxyacanthus and C. creticus, have successfully been crossed with C. tinctorius to produce fertile hybrids. Data from artificial crosses resulting in fertile offspring indicate the biological potential of a hybridization event, but only if the species are temporally and spatially sympatric can this occur. Based on the New World distribution of C. oxyacanthus and C. creticus we predict that hybridization with transgenic C. tinctorius could occur in some areas of Argentina, Chile and localities within several states in the United States including California, Florida, Illinois, Kansas, New Mexico, Ohio, Oklahoma, Oregon, Utah, and Texas. Locations in the New World where wild species of Carthamus have not been naturalized may provide biologically isolated locations for the cultivation of a transgenic safflower crop. On s'intéresse au carthame (Carthamus tinctorius L.) pour la production de substances pharmaceutiques végétales par le biais d'un système de protéines hybrides de l'oléosine. Les auteurs ont tenté d'évaluer les risques de flux génétique entre le carthame et les espèces sauvages ou adventices apparentées qu'on trouve dans l'ouest du Canada. Les études cytogénétiques et phylogénétiques sur la majorité des espèces du genre Carthamus indiquent que le carthame pourrait se reproduire avec au moins six espèces sauvages ou adventices dans le monde. Sur les quatre qui se sont acclimatées en Amérique, seules C. oxyacanthus et C. creticus ont donné des hybrides fertiles après croisement avec C. tinctorius. Les données sur les croisements qui ont abouti à des hybrides fertiles nous renseignent sur le potentiel biologique d'hybridation, mais un croisement ne peut survenir que si les deux espèces sont sympatriques dans le temps et l'espace. Compte tenu de l'aire de distribution de C. oxyacanthus et de C. creticus en Amérique, les auteurs estiment qu'il pourrait y avoir hybridation dans certaines parties de l'Argentine, du Chili et de plusieurs États américains, dont la Californie, la Floride, l'Illinois, le Kansas, le Nouveau-Mexique, l'Ohio, l'Oklahoma, l'Orégon, l'Utah et le Texas. Les endroits d'Amérique où les espèces sauvages du genre Carthamus ne se sont pas acclimatées pourraient constituer des endroits biologiquement isolés où l'on pourrait cultiver le carthame transgénique.

“…Genetic information on yield per head in safflower is not available. Ashri and Efron (1964), Imrie and Knowles ( 1970), and Kotecha (1977) reported that anthocyanin pigmentation of the cotyledonary midvein was controlled by one locus, with the allele for purple midvein being recessive to that for green.…”

The chapter deals with the biology, breeding, and transgene research of safflower ( Carthamus tinctorius L.), an important source of edible oil rich in unsaturated fatty acids. A brief description of its origin, domestication, introduction to other countries, current distribution, and major uses is followed by details about its habit, habitat, taxonomy, cytogenetics, genetic resources, and economic importance. Traditional breeding of this crop has primarily been carried out to improve the oil yield and quality, develop male sterile lines, and incorporate traits for resistance/tolerance to abiotic and biotic stresses. Because of the assiduous and time‐consuming nature of the traditional breeding, efforts have been initiated to improve this crop by biotechnological methods, especially genetic transformation. Most of these studies are preliminary and demonstrative in nature, except two: one leading to the development of genetically transformed safflower capable of synthesizing insulin in its seeds and the other incorporating a gene coding for a specific esterase, capable of hydrolyzing a phototoxic from Alternaria carthami , a pathogen causing devastating leaf blight disease of safflower. Besides emphasizing the importance and implications of these studies, transgenes, transformation methods, and selection procedures utilized in such studies have been described. The chapter is concluded by discussing some of the future goals of transgene research on safflower, probable environmental risks because of the products so developed, and possible biosafety measures.
