“…The relative importance of the S locus, however, is controversial (Hogenboom 1975). The observations that there are exceptions to the rule and SI # SC that the physiology, location, and timing of pollen tube arrest of UI is different than the SI reaction (Liedl et al 1996) contribute to the controversy.…”

“…In general, crosses within the genus Lycopersicon conform to the rule. For ex-SI # SC ample, pollen from SC Lycopersicon esculentum fails to fertilize SI Lycopersicon peruvianum, while the reciprocal cross succeeds (Bohn 1948;Hogenboom 1972;de Nettancourt et al 1974). Similarly, L. esculentum pollen does not grow in the styles of Lycopersicon [Solanum] pennellii or of Lycopersicon hirsutum, while the reciprocal crosses successfully set seed (Rick 1960;Martin 1961bMartin , 1963Martin , 1964Liedl et al 1996).…”

Parental conflicts can lead to antagonistic coevolution of the sexes and of parental genomes. Within a population, the resulting antagonistic effects should balance, but crosses between populations can reveal conflict. Parental conflict is less intense in selfpollinating plants than in outcrossers because outcrossing plants are pollinated by multiple pollen donors unrelated to the seed parent, while a self-pollinating plant is primarily pollinated by one individual (itself). Therefore, in crosses between plants with differing mating systems, outcrossing parents are expected to "overpower" selfing parents. We call this the weak inbreeder/strong outbreeder (WISO) hypothesis. Prezygotically, such overpowering can alter pollination success, and we argue that our hypothesis explains a common pattern of unilateral incompatibility, in which pollen from self-incompatible populations fertilizes ovules of self-compatible individuals but the reciprocal cross fails. A postzygotic manifestation of overpowering is aberrant seed development due to parent-of-origin effects such as genomic imprinting. We evaluate evidence for the WISO hypothesis by reviewing published accounts of crosses between plants of different mating systems. Many, but not all, of such reports support our hypothesis. Since parental conflicts can perturb fertilization and development, such conflicts may strengthen reproductive barriers between populations, contributing to speciation.

“…Crossing barriers between LE X LP have been circumvented by using interspecific chimeras (Gunther, 1964) or inbred LP lines selected for congruity to LE (Hogenboom, 1972b) . These methods, however, are tedious and effective only with limited LP genotypes .…”

Treatment of Lycopersicon peruvianum stigmas with an artificial medium analogous to stigmatic exudate allowed pollen germination and growth on immature pistils . Growth of Lycopersicon esculentum pollen tubes to L . peruvianum ovules, an otherwise incompatible cross, was achieved following such treated bud-pollinations . No plantlets were recovered, although a few embryos from this cross at the globular to heart stage of development were excised at 22 days after pollination, indicating the presence of crossing failures as severe as in the reciprocal cross . Hybrid plants were obtained from the reciprocal cross, using as pollen parent an L . peruvianum line selected for congruity with L . esculentum . Bud pollinations to L . peruvianum, using these interspecific F l hybrids as the pollen parent, allowed viable embryo development and plantlet recovery . Resulting backcross plants, which possess approximately 1/4 L . esculentum genome in a L . peruvianum cytoplasm, may facilitate further introgression of the L . esculentum nuclear genes into a foreign cytoplasm .

“…Hogenboom (1972) was able to overcome the inhibition of Lycopersicon esculentum pollen tube growth in the style of L . peruvianum by selfing the latter prior to hybridization and hence obtaining homozygous plants carrying recessive genes .…”

Overcoming the barrier to interspecific hybridization of Fagopyrum esculentum with Fagopyrum tataricum

et al. 1996

Tartary buckwheat (Fagopyrum tataricum) was successfully hybridized with common buckwheat (F esculentum), both diploid (2n = 16), using the latter as male parent during bud pollination . The barrier normally encountered in such hybridization was overcome by enhancing the cross-compatibility of the two species, which was accomplished by synthesizing a unique genotype of common buckwheat . This novel plant was produced by selecting common buckwheat plants that exhibited, at isozyme loci PGM, SKDH and ADH, alleles with similar mobility to those found in tartary and then transferring these alleles to a single plant through six generations of breeding . Ovule culture was used to rescue the 7-10 day old embryos . On the rescue-culture medium 41% of the hybrid embryos formed calli larger than 200 pm in diameter. Most ceased to grow before reaching 1500 µm, but four out of 263 cultured ovules continued to grow as callus . One of these differentiated and formed callus with buds and shoots from which cloned plants were produced . The remaining embryos either did not grow at all or formed very small calli . When tartary was crossed with the original genotype of common buckwheat, only 22% of the hybrid embryos formed small calli and none differentiated . Hybridity of the calli and the plantlets was determined by RAPD and isozyme analysis, respectively . Flowers produced by the hybrid plants were of the same type (homomorphic) and size as those of tartary, but with white sepals like common buckwheat .
