“…Other method suggested by different workers has little application in mass multiplication of self-incompatible lines and are not much reliable. These includes steel brush pollination (Roggen and Van Digk, 1972), double pollination (Ockendon and Currah, 1978), electric aid pollination (Roggen at al. 1972), end season pollination (Fraser, 1984 andOckendon, 1978), heat treatment (Johnson, 1971 andVan Dijk, 1976), and organic solvent treatment (Gonai andHinata, 1989 andOckendon, 1978) of stigma in Brassica olerecea.…”

Cauliflower is an important vegetable crop which belongs to the family Brassicaceae and is grown in many countries like India, China, Italy, Europe, America, etc. It is grown for its highly suppressed 'prefloral fleshy apical meristem' branches called "curd." It is a cross-pollinated crop. There are different groups based on their characteristics. Multiple pollination mechanisms, e.g., self-incompatibility and male sterility, not only encourages cross-pollination but also found useful in the commercial hybrid seed production of the crop. As the main hindrance to the popularization of F 1 hybrids is unavailability and high cost of hybrid seed. In cauliflower, F 1 hybrids have been found advantageous for earliness, high early and total yield, better curd quality with respect to compactness and color, uniform maturity, resistance to insect pest, diseases and unfavorable weather conditions.

“…The second is the double-cross hybrid previously reported in Brassica and Raphanus (Odland 1950), which was improved and suggested in B. napus (Gowers 1975). SI can be overcome by treatment with bud pollination, thermally aided pollination (Roggen and Dijk 1976), electrically aided pollination (Roggen et al 1972), NaCl solution (An et al 1989;Fu et al 1992), and/or CO 2 gas (Nakanishi et al 1969). The NaCl solution and CO 2 gas have been proved effective and are frequently used in Brassica vegetables, but these methods are laborious and time consuming with high costs and strict techniques that are unsuitable for a field crop to propagate the SI line in large quantities.…”

Self-incompatibility (SI) is a widespread mechanism in flowering plants that promotes outbreeding and thereby increases genetic diversity. Recognition specificity in Brassica is achieved by the interaction of the female determinant S-receptor kinase (SRK) and its ligand, the male determinant S-locus protein 11 (SP11). The interaction between SP11 and SRK triggers the signaling cascade in an S-haplotype-specific manner and results in the rejection of self-pollen, but the signal components involved are still not well characterized. S haplotypes are widespread in self-compatible amphidiploid B. napus, and the interaction of heterozygous S haplotypes causes the loss of SI. This review highlights the recent advances made towards understanding the genetic analysis, distribution, and evolution of S haplotypes, the signal factors, and the potential of SI in B. napus hybrid breeding program.

“…Extensive research has been conducted to overcome problems related to SI. Many reports have appeared that describe the successful breakdown of the sporophytictype SI of Brassicaceae using a variety of techniques, such as bud pollination, old-flower pollination, and pretreatment of the pistil with carbon dioxide, hot water, salt, or electricity (Kakizaki, 1930;Nakanishi and Hinata, 1973;Okazaki and Hinata, 1987;Roggen et al, 1972;Tlngdong et al, 1992). In addition, techniques such as old-flower pollination, pre-treatment of the pistil with hot water, and stigma excision are effective at overcoming gametophytic-type SI in Liliaceae (Ascher and Peloquin, 1966;Hopper et al, 1967;Okazaki and Murakami, 1992).…”

Artificial Control of the <i>Prunus</i> Self-incompatibility System Using Antisense Oligonucleotides Against Pollen Genes

Prunus (Rosaceae) includes many commercially important fruit crop species that exhibit self-incompatibility (SI), including sweet cherry (P. avium L.), Japanese apricot (P. mume Sieb. et Zucc.), Japanese plum (P. salicina Lindl.), apricot (P. armeniaca L.), and almond (P. dulcis [Mill.] D. A. Webb.). These species exhibit S-ribonuclease-based gametophytic SI, which prevents self-pollen tube growth in the pistil. The successful production of self-fertilized progeny accomplished by artificially overcoming the SI barrier has not been reported in Prunus, but self-compatible (SC) Prunus mutants with mutated pollen S determinant S haplotypespecific F-box (SFB) or pollen modifier M-locus encoded glutathione S-transferase-like (MGST) genes have been identified and used as SC cultivars and breeding stocks. In this study, we suppressed translation of SFB or MGST mRNA in self-pollen using antisense oligonucleotides to overcome the SI barrier in P. avium, P. mume, and P. salicina. Over the three years of the study, we obtained self-fertilized progeny of SI Japanese plum 'Sordum' only when SFB or MGST was knocked down. We also found that the average length of the self-pollinated pollen tube in the pistil of 'Sordum' was increased following treatment with an antisense oligonucleotide against SFB. This is the first report regarding the successful production of selfed progeny of Prunus obtained by disrupting SI. Our findings also provide evidence that the loss of function of SFB or MGST in Prunus pollen leads to SC.
