Abstract
Introduction The self-incompatibility system in sweet cherry (Prunus avium L.) prevents fertilization with own or genetically related pollen, and is genetically determined by the multi-allelic S-locus. Therefore, determining S-alleles is crucial for plant breeding and fruit production, as it enables the selection of compatible combinations of S-genotypes for successful pollination. Methods In this study, S-alleles were identified in a total of 260 genotypes from the Caucasian region, the species' center of origin. S-allele genotyping was conducted using PCR fragment length analysis with the standard marker PaConsI-F/R2 and reference genotypes, complemented by sequence analysis through amplicon deep sequencing. Results and discussion The genotypes collected from Azerbaijan and Turkey exhibit a high allelic richness at the S-locus, particularly compared to modern sweet cherry cultivars worldwide. Nine previously undescribed S-alleles were identified and designated as S45, S46, S47, S48, S49, S50, S51, S52 and S53. Given the expected high diversity for other traits, this plant material represents a valuable resource for further breeding research and introgression of new traits in future breeding programs. Furthermore, our results underscore that fragment length alone may not be sufficient for unambiguous assignment of S-alleles due to minimal length differences between different alleles. To address this issue, an S-allele reference ladder was developed using the rich diversity for precise assignment of the S-alleles. This tool can be applied in future experiments as a robust and cost-effective method for accurate S-genotyping across different runs and laboratories. Additionally, several selected S-genotypes were planted in a trial field and will be maintained as an S-allele reference collection.

Self-(In)Compatible MGST- and S-Alleles Using Capillary Fragment Analysis. Int J Mol Sci 2023; 24:ijms24086931.

Abstract
The sweet cherry plant (Prunus avium L.) is primarily self-incompatible, with so-called S-alleles responsible for the inability of flowers to be pollinated not only by their own pollen grains but also by pollen from other cherries having the same S-alleles. This characteristic has wide-ranging impacts on commercial growing, harvesting, and breeding. However, mutations in S-alleles as well as changes in the expression of M locus-encoded glutathione-S-transferase (MGST) can lead to complete or partial self-compatibility, simplifying orchard management and reducing possible crop losses. Knowledge of S-alleles is important for growers and breeders, but current determination methods are challenging, requiring several PCR runs. Here we present a system for the identification of multiple S-alleles and MGST promoter variants in one-tube PCR, with subsequent fragment analysis on a capillary genetic analyzer. The assay was shown to unequivocally determine three MGST alleles, 14 self-incompatible S-alleles, and all three known self-compatible S-alleles (S3', S4', S5') in 55 combinations tested, and thus it is especially suitable for routine S-allele diagnostics and molecular marker-assisted breeding for self-compatible sweet cherries. In addition, we identified a previously unknown S-allele in the 'Techlovicka´ genotype (S54) and a new variant of the MGST promoter with an 8-bp deletion in the ´Kronio´ cultivar.

Abstract
DNA from four sweet cherry seedlings derived from gamma-irradiated female parents was sequenced via nanopore technology (Oxford Nanopore MinION). Total data yield was 8.07 Gb, ranging from 0.92 to 3.36 Gb per sample, with the average length of mapped reads ranging from 22 Kbp–24 Kbp. Sequence data was then analysed to identify and characterize variants using a published sweet cherry reference genome. Small and medium-sized indels (55–135 bp), as well as structural variants, including several large indels and complex variants were detected. Of these, 20 variants were localized within protein-coding gene sequences, including those encoding a putative F-box protein, an ADP-ribose glyxohydrolase protein, a predicted 26S protease regulatory subunit, an E3 ubiquitin protein ligase, a UDP-galactose/UDP-blucose transporter, an alpha/beta hydrolase domain-containing protein, a rhodanese-like domain-containing protein, a cytochrome p450 protein, phosphoinositide phosphatase, cysteine synthase-like, phosphoenolpyruvate carboxylase 4, and several uncharacterized proteins. These variations could have functional and phenotypic consequences that are useful in basic research and breeding.

Abstract
Pedigree information is of fundamental importance in breeding programs and related genetics efforts. However, many individuals have unknown pedigrees. While methods to identify and confirm direct parent-offspring relationships are routine, those for other types of close relationships have yet to be effectively and widely implemented with plants, due to complications such as asexual propagation and extensive inbreeding. The objective of this study was to develop and demonstrate methods that support complex pedigree reconstruction via the total length of identical by state haplotypes (referred to in this study as "summed potential lengths of shared haplotypes", SPLoSH). A custom Python script, HapShared, was developed to generate SPLoSH data in apple and sweet cherry. HapShared was used to establish empirical distributions of SPLoSH data for known relationships in these crops. These distributions were then used to estimate previously unknown relationships. Case studies in each crop demonstrated various pedigree reconstruction scenarios using SPLoSH data. For cherry, a full-sib relationship was deduced for 'Emperor Francis, and 'Schmidt', a half-sib relationship for 'Van' and 'Windsor', and the paternal grandparents of 'Stella' were confirmed. For apple, 29 cultivars were found to share an unknown parent, the pedigree of the unknown parent of 'Cox's Pomona' was reconstructed, and 'Fameuse' was deduced to be a likely grandparent of 'McIntosh'. Key genetic resources that enabled this empirical study were large genome-wide SNP array datasets, integrated genetic maps, and previously identified pedigree relationships. Crops with similar resources are also expected to benefit from using HapShared for empowering pedigree reconstruction.

Abstract
Self-incompatibility in Prunus (Rosaceae) species, such as sweet cherry, is controlled by a multiallelic locus (S), in which two tightly linked genes, S-RNase and SFB (S haplotype-specific F-box), determine the specificity of the pollen and the style. Fertilization in these species occurs only if the S-specificities expressed in the pollen and the pistils are different. However, modifier genes have been proposed to be necessary for a full manifestation of the self-incompatibility response. 'Cristobalina' is a spontaneous self-compatible sweet cherry cultivar that originated in Eastern Spain. Previous studies with this genotype suggested that pollen modifier gene(s), not linked to the S-locus, may be the cause of self-incompatibility breakdown. In this work, an F(1) population from 'Cristobalina' that segregates for this trait was used to identify molecular markers linked to self-compatibility by bulked segregant analysis. One simple sequence repeat (SSR) locus (EMPaS02) was found to be linked to self-compatibility in this population at 3.2 cM. Two additional populations derived from 'Cristobalina' were used to confirm the linkage of this marker to self-compatibility. Since EMPaS02 has been mapped to the sweet cherry linkage group 3, other markers located on the same linkage group were analysed in these populations to confirm the location of the self-compatibility locus.

Abstract
Background Domestication and breeding involve the selection of particular phenotypes, limiting the genomic diversity of the population and creating a bottleneck. These effects can be precisely estimated when the location of domestication is established. Few analyses have focused on understanding the genetic consequences of domestication and breeding in fruit trees. In this study, we aimed to analyse genetic structure and changes in the diversity in sweet cherry Prunus avium L. Results Three subgroups were detected in sweet cherry, with one group of landraces genetically very close to the analysed wild cherry population. A limited number of SSR markers displayed deviations from the frequencies expected under neutrality. After the removal of these markers from the analysis, a very limited bottleneck was detected between wild cherries and sweet cherry landraces, with a much more pronounced bottleneck between sweet cherry landraces and modern sweet cherry varieties. The loss of diversity between wild cherries and sweet cherry landraces at the S-locus was more significant than that for microsatellites. Particularly high levels of differentiation were observed for some S-alleles. Conclusions Several domestication events may have happened in sweet cherry or/and intense gene flow from local wild cherry was probably maintained along the evolutionary history of the species. A marked bottleneck due to breeding was detected, with all markers, in the modern sweet cherry gene pool. The microsatellites did not detect the bottleneck due to domestication in the analysed sample. The vegetative propagation specific to some fruit trees may account for the differences in diversity observed at the S-locus. Our study provides insights into domestication events of cherry, however, requires confirmation on a larger sampling scheme for both sweet cherry landraces and wild cherry.

Abstract
European pear exhibits RNase-based gametophytic self-incompatibility controlled by the polymorphic S-locus. S-allele diversity of cultivars has been extensively investigated; however, no mutant alleles conferring self-compatibility have been reported. In this study, two European pear cultivars, 'Abugo' and 'Ceremeño', were classified as self-compatible after fruit/seed setting and pollen tube growth examination. S-genotyping through S-PCR and sequencing identified a new S-RNase allele in the two cultivars, with identical deduced amino acid sequence as S(21), but differing at the nucleotide level. Test-pollinations and analysis of descendants suggested that the new allele is a self-compatible pistil-mutated variant of S(21), so it was named S(21)*. S-genotypes assigned to 'Abugo' and 'Ceremeño' were S(10)S(21)* and S(21)*S(25) respectively, of which S(25) is a new functional S-allele of European pear. Reciprocal crosses between cultivars bearing S(21) and S(21)* indicated that both alleles exhibit the same pollen function; however, cultivars bearing S(21)* had impaired pistil-S function as they failed to reject either S(21) or S (21)* pollen. RT-PCR analysis showed absence of S(21)* -RNase gene expression in styles of 'Abugo' and 'Ceremeño', suggesting a possible origin for S(21)* pistil dysfunction. Two polymorphisms found within the S-RNase genomic region (a retrotransposon insertion within the intron of S(21)* and indels at the 3'UTR) might explain the different pattern of expression between S(21) and S(21)*. Evaluation of cultivars with unknown S-genotype identified another cultivar 'Azucar Verde' bearing S(21)*, and pollen tube growth examination confirmed self-compatibility for this cultivar as well. This is the first report of a mutated S-allele conferring self-compatibility in European pear.

Abstract
Prunus dulcis, the almond, is a predominantly self-incompatible (SI) species with a gametophytic self-incompatibility system mediated by S-RNases. The economically important allele Sf, which results in self-compatibility in P. dulcis, is said to have arisen by introgression from Prunus webbii in the Italian region of Apulia. We investigated the range of self-(in)compatibility alleles in Apulian material of the two species. About 23 cultivars of P. dulcis (14 self-compatible (SC) and nine SI) and 33 accessions of P. webbii (16 SC, two SI and 15 initially of unknown status), all from Apulia, were analysed using PCR of genomic DNA to amplify S-RNase alleles and, in most cases, IEF and staining of stylar protein extracts to detect S-RNase activity. Some amplification products were cloned and sequenced. The allele Sf was present in nearly all the SC cultivars of P. dulcis but, surprisingly, was absent from nearly all SC accessions of P. webbii. And of particular interest was the presence in many SI cultivars of P. dulcis of a new active allele, labelled S30, the sequence of which showed it to be the wild-type of Sf so that Sf can be regarded as a stylar part mutant S30 degrees . These findings indicate Sf may have arisen within P. dulcis, by mutation. One SC cultivar of P. dulcis, 'Patalina', had a new self-compatibility allele lacking RNase activity, Sn5, which could be useful in breeding programmes. In the accessions of P. webbii, some of which were known to be SC, three new alleles were found which lacked RNase activity but had normal DNA sequences.

Abstract
In China, its centre of origin, apricot (Prunus armeniaca) is self-incompatible. However, most European cultivars are self-compatible. In most cases, self-compatibility is a result of a loss-of-function mutation within the pollen gene (SFB) in the SC haplotype. Controlled pollinations performed in this work revealed that the cross 'Ceglédi óriás' (S8S9)x'Ceglédi arany' (SCS9) set well, as expected, but the reciprocal cross did not. Apricot S8, S9 and SC haplotypes were analysed using a multilevel approach including fruit set evaluation, pollen tube growth analysis, RNase activity assays, polymerase chain reaction (PCR) analysis and DNA sequencing of the S-RNase and SFB alleles. SFB8 was revealed to be the first known progenitor allele of a naturally occurring self-compatibility allele in Prunus, and consequently SC=The first intron of SC-RNase is a phase one intron, indicating its more recent evolutionary origin compared with the second intron. Sequence analysis of different cultivars revealed that more single nucleotide polymorphisms accumulated in SC-RNase than in SFBC. New methods were designed to allow high-throughput analysis of S genotypes of apricot cultivars and selections. S-RNase sequence data from various sources helped to elucidate the putative origin and dissemination of self-compatibility in apricot conferred by the SC haplotype.

Abstract
This study demonstrates that self-compatible (SC) peach has mutant versions of S haplotypes that are present in self-incompatible (SI) Prunus species. All three peach S haplotypes, S (1), S (2), and S (2m), found in this study encode mutated pollen determinants, SFB, while only S (2m) has a mutation that affects the function of the pistil determinant S-RNase. A cysteine residue in the C5 domain of the S (2m)-RNase is substituted by a tyrosine residue, thereby reducing RNase stability. The peach SFB mutations are similar to the SFB mutations found in SC haplotypes of sweet cherry (P. avium) and Japanese apricot (P. mume). SFB (1) of the S (1) haplotype, a mutant version of almond (P. dulcis) S (k) haplotype, encodes truncated SFB due to a 155 bp insertion. SFB (2) of the S (2) and S (2m) haplotypes, both of which are mutant versions of the S (a) haplotype in Japanese plum (P. salicina), encodes a truncated SFB due to a 5 bp insertion. Thus, regardless of the functionality of the pistil determinant, all three peach S haplotypes are SC haplotypes. Our finding that peach has mutant versions of S haplotypes that function in almond and Japanese plum, which are phylogenetically close and remote species, respectively, to peach in the subfamily Prunoideae of the Roasaceae, provides insight into the SC/SI evolution in Prunus. We discuss the significance of SC pollen part mutation in peach with special reference to possible differences in the SI mechanisms between Prunus and Solanaceae.

Abstract
Gametophytic self-incompatibility (GSI) is an outcrossing mechanism in flowering plants that is genetically controlled by 2 separate genes located at the highly polymorphic S-locus, termed S-haplotype. This study characterizes a pollen part mutant of the S(1)-haplotype present in sour cherry (Rosaceae, Prunus cerasus L.) that contributes to the loss of GSI. Inheritance of S-haplotypes from reciprocal interspecific crosses between the self-compatible sour cherry cultivar Ujfehértói Fürtös carrying the mutated S(1)-haplotype (S(1)'S(4)S(d)S(null)) and the self-incompatible sweet cherry (Prunus avium L.) cultivars carrying the wild-type S(1)-haplotype revealed that the mutated S(1)-haplotype confers unilateral incompatibility with a functional pistil component and a nonfunctional pollen component. The altered sour cherry S(1)-haplotype pollen part mutant, termed S(1)', contains a 615-bp Ds-like element within the S(1)-haplotype-specific F-box protein gene (SFB(1)'). This insertion generates a premature in-frame stop codon that would result in a putative truncated SFB(1) containing only 75 of the 375 amino acids present in the wild-type SFB(1). S(1)' along with 2 other previously characterized Prunus S-haplotype mutants, S(f) and S(6m), illustrate that mobile element insertion is an evolutionary force contributing to the breakdown of GSI.

Abstract
PCR-based identification of all 13 known self-incompatibility (S) alleles of sweet cherry is reported. Two pairs of consensus primers were designed from our previously published cDNA sequences of S(1) to S(6) S-RNases, the stylar components of self-incompatibility, to reveal length variation of the first and the second introns. With the exception of the first intron of S(13), these also amplified S(7) to S(14) and an allele previously referred to as S(x), which we now label S(16). The genomic PCR products were cloned and sequenced. The partial sequence of S(11) matched that of S(7) and the alleles were shown to have the same functional specificity. Allele-specific primers were designed for S(7) to S(16), so that allele-specific primers are now available for all 13 S alleles of cherry (S(8), S(11) and S(15) are duplicates). These can be used to distinguish between S alleles with introns of similar size and to confirm genotypes determined with consensus primers. The reliability of the PCR with allele-specific primers was improved by the inclusion of an internal control. The use of the consensus and allele-specific primers was demonstrated by resolving conflicting genotypes that have been published recently and by determining genotypes of 18 new cherry cultivars. Two new groups are proposed, Group XXIII (S(3) S(16)), comprising 'Rodmersham Seedling' and 'Strawberry Heart', and Group XXIV (S(6) S(12)), comprising 'Aida' and 'Flamentiner'. Four new self-compatibility genotypes, S(3) S(3)', S(4)' S(6), S(4)' S(9) and S(4)' S(13), were found. The potential use of the consensus primers to reveal incompatibility alleles in other cherry species is also demonstrated.

Abstract
A 2-locus model of the evolution of self-incompatibility in a population practicing partial selfing is presented. An allele is introduced at a modifier locus which influences the strength of the rejection reaction expressed by the style in response to antigens recognized in pollen. Two causes of inbreeding depression are investigated. First, offspring viability depends solely on the source (self or non-self) of the fertilizing pollen. Second, offspring viability declines with the expression of recessive deleterious alleles, segregating at a third (disease) locus, which exhibit an imperfect association with antigen alleles. Evolutionary changes occurring at the disease locus are not considered in this study. The condition under which a modifier allele that intensifies the incompatibility reaction increases when rare depends upon the number of antigens, the frequency of recessive deleterious alleles at the disease locus, and the level of association between the antigen locus and the disease locus. It is the improvement of viability among offspring derived by outcrossing, rather than the prevention of self-fertilization, that may represent the primary evolutionary function of genetic incompatibility systems.

Abstract
A previously identified S-linked stylar-inactivation PSC factor (Flaschenriem and Ascher 1979b) was studied for its location relative to S. Plants exhibiting complete stylar-inactivation PSC were those with higher multigenic PSC background level than plants with only S-linked partial stylar-inactivation PSC. A pollen-mediated pseudo-self compatibility (PMPSC) adjustment factor was offered as a device to focus on stylar-inactivation PSC by removing some male origin, multigenic PSC. The stylar inactivation factor was not tightly linked to S but affected expression of only the allele to which it was linked. A three part interacting association of genetic material governing self incompatibility (SI) is proposed. The parts of S are the SI identity gene, S-specific PSC genes and, finally, PSC genes which are not S-specific in action. The complete association is termed the SI-complex.

Abstract
Pseudo-self-compatibility (PSC) in Nemesia strumosa was determined by recessive modifying genes which interferred with the normal stylar incompatibility reaction. The PSC levels ranged from none or low to amounts resembling full self-compatibility. PSC within a progeny could be maintained at low or high levels by selecting parents either high or low in PSC. Pollen from plants of any PSC level failed to produce seed when placed on other incompatible styles bearing the same S alleles.

Abstract
Flovering plants from a self-incompatible clone ofLycopersicum peruvianum were exposed during 90 days to different dose-rates of gamma-rays ranging from 2 to 17 rad perhour. Irradiation was continuous, except for a daily interruption of 7 hours.Whereas irradiation at dose-rates higher than 7.50 rad per hour seriously inhibited bud formation and floral development, chronic exposure at dose-rates ranging from 3 to 7 rad/hour increased the number of seeds per plant. This stimulation is not due to a higher number of seeds per fruit but to a very significant rise in the number of fruits per plant. As irradiation treatment did not significantly increase the number of flowers per plant and did not appear to stimulate pollen tube germination in the styles, it is concluded that the recorded increase in fruit-setting essentially resulted from a radio-induced inhibition of the processes which control floral abscission in the absence of cross-pollination.Three plants with reduced self-incompatibility and one completely parthenocarpic individual were observed in theM 2 progeny but no evidence was obtained that irradiation could induce a permanent type of self-compatibility inL. peruvianum.
