The following information was supplied regarding data availability:. Vitis vinifera can be divided into two subspecies, V. Three flower types can be observed: hermaphrodite and female on some varieties in vinifera , and male or female flowers in sylvestris. It is assumed that the different flower types in the wild ancestor arose through specific floral patterns of organ abortion.

A considerable amount of data about the diversity of sexual systems in grapevines has been collected over the past century. Several grapevine breeding studies led to the hypothesis that dioecy in vinifera is derived from a hermaphrodite ancestor and could be controlled by either, one or two linked genetic determinants following Mendelian inherence.

More recently, experiments using molecular approaches suggested that these loci were located in a specific region of the chromosome 2 of vinifera. Based on the works published so far, its seems evident that a putative sex locus is present in chromosome 2. However, it is still not fully elucidated whether flower types are regulated by two linked loci or by one locus with three alleles.

Nevertheless, several genes could contribute to sex determination in grapevine. This review presents the results from early studies, combined with the recent molecular approaches, which may contribute to the design of new experiments towards a better understanding of the sex inheritance in grapevine. The cultivated grapevine Vitis vinifera subsp. Among this family, species from the genus Vitis are found mainly in temperate zones of the Northern Hemisphere distributed between North America and eastern Asia.

In the case of V. Evolutionary genomic analysis showed that vinifera diverged from V. Zhou et al. McGovern, However, more recent archaeological samples from the south Caucasus, suggest that wine making go as far as 8, years McGovern et al.

Therefore, the domestication process might have occurred earlier than the records show. The domestication and cultivation of vinifera then spread to what is today the Palestine, southern Lebanon and Jordan McGovern, By 2, B. The domestication of vinifera is linked with the discovery of wine production, as well as, other products such as raisins, table grapes and grape vinegar, making this species a major agronomic and economic crop worldwide Hardie, ; Royer, Vitis genus itself has two subgenera: Vitis and Muscadinia Vitis rotundifolia , both producing edible fruits Olien, Despite the karyotype difference, crossing between V.

However there is a high sterility in the F1 hybrids with few or no viable seeds. This might be explained by the phylogenetic proximity between the two subgenera confirmed by chloroplastic gene markers Ingrouille et al.

Cytological analysis performed during pollen meiosis of F1 offspring of V. However, not only in situ hybridisation on V. However, more recently the hypothesis of a polyploid origin of Vitis found strong support with the publication of the grapevine genome Jaillon et al.

The authors of this review article are familiar with grapevine genetics, flower development, physiology and new generation sequencing techniques, having published several scientific manuscripts regarding the subject. Scientific articles, diverse in date of publishing, considered relevant on the subject were selected.

Flowers of wild grapevines are mainly of two types: male with suppressed pistils Fig. However, in rare instances, female flowers producing fertile pollen appear in wild plants Valleau, Dissected flowers from Vitis vinifera sylvestris.

A and B Male flower of V. B In male flowers, it is possible to observe the undeveloped pistil and in C females the reflex stamens, that produce infertile pollen. Photo credit: Margarida Rocheta. Variations in the development and functional ability of stamens and pistils of the three grapevine flower types have been reported Stout, although, these differences were considered as being quantitative rather than qualitative.

Clear differences were observed among hermaphrodite flowers regarding filament length, anther size, pistil shape Figs. In female flowers, Stout described a gradual phenotype regarding the reflexed stamen development Figs. Pollen grains were irregular, shrivelled and an only few were able to germinate Stout, Scheme of some possible morphologic variations in stamens and pistils on hermaphrodite, female and male flowers according to Stout A—C Hermaphrodite plants hold both functional organs but might show variation in B stamens and C pistil size.

D—H Female flowers show a functional pistil but several types of non-functioning stamens producing infertile pollen. I and J Male plants exhibit several variations of non-functional pistils but fully functional stamens with variable size. In accordance with a previous study Dorsey, , Stout showed that in male plants, the functional stamens may also vary in size Figs.

Carpels and rudimentary ovules were produced with seed coats not fully developed Dorsey, and none of them were able to produce fruits Stout, Diagram of the morphologic differences in the pistil of male flowers according to Stout A Include well-formed but non-functional pistils, B and C pistils with different sizes, and D a non-functional pistil with the complete absence X of style and stigma.

In the middle of 20th century, Levadoux shed light on the differences between vinifera and sylvestris of western Eurasia and concluded that no morphological character allowed a specific differentiation between them since hermaphrodite plants could also occur in sylvestris. Later, several authors contributed to clarify the floral and reproductive development of vinifera and sylvestris in more detail Caporali et al.

The morphological differentiation between male and female flowers of the dioecious grapevine can only be identified at a late stage of flower development, since at early stages a hermaphrodite development pattern is observed Caporali et al. Although male flower pistils are not fully developed, the ovule development occurs, followed by megasporogenesis and megagametophyte formation Caporali et al. The suppression of femaleness appears to be the consequence of the death of a specific layer, or layers, of nucellar cells and ovular integuments, which may represent the targets of a programmed cell death or apoptosis process Caporali et al.

In female flowers, the suppression of maleness appears to be the consequence of pollen sterility Caporali et al. Comparing to male flowers microspores, female microspores have been shown to have an abnormal, round shape, without distinct colpi, and lack the typical thickenings Caporali et al.

The anthers of female flowers produce much less pollen grains 10— than the male 1,—3, Gallardo et al. The authors self-pollinated grapevines exhibiting upright stamens, reflexed stamens and performed crosses between these two types of grapevines.

The interpretation of these results proposed that grapevine sex specification should be regulated by two determinants, F female and M male Valleau, and assumed that female plants are homozygous, FF, and males are heterozygous, FM. In the hermaphrodites both determinants would be linked giving rise to heterozygous individuals represented by FH of Hermaphrodite Table 1. The flower phenotypes from crosses between female and the different hermaphrodite types, allowed the conclusion that the hermaphrodites could be either FH or HH Valleau, Table 1.

Several crosses between hermaphrodite and male plants revealed that MH male plants should also exist Valleau, The most comprehensive work on the inheritance of flower sex in vinifera was carried out in , and it was suggested that flower sex determination in grapes was due to a digenic linked inheritance Oberle, The author assumed a homozygous condition in female plants, a heterozygous condition for the functionally male plants, and a heterozygous or a homozygous condition in the hermaphrodites.

Also, it was proposed that the action of recessive genes resulted in male sterility and the action of dominant ones resulted in female sterility. Oberle named the dominant allele responsible for perfect pollen development as Sp , the recessive allele that inhibits pollen development as sp , the dominant allele that inhibits ovule development as So and the recessive allele responsible for perfect ovule development as so Fig. The flower phenotypes observed in crosses between male vs female, female vs hermaphrodite and male vs hermaphrodite plants followed a Mendelian inheritance, and the ratios calculated from the crosses performed by Oberle were similar to those obtained by Valleau According to the authors, the crosses between hermaphrodites could only originate hermaphrodites or hermaphrodites and females in a ratio, depending on the hermaphrodite genotype.

Homozygous hermaphrodites crossed with males of any genotype originated ratio of male to hermaphrodite progeny.

Heterozygous hermaphrodites crossed to heterozygous males originated ratio of male:hermaphrodite:female progeny. However, females crossed with heterozygous hermaphrodites the resulting proportion was of female and hermaphrodites. Finally, the crosses between male and female plants, originated proportion of males and hermaphrodites or males and females, depending on the possible male genotypes.

In a later work, several self-pollination and crosses with different cultivated hermaphrodite varieties were performed Avramov et al.

The authors obtained two sets of results: hermaphrodite and female plants in a ratio, and an offspring of only hermaphrodite individuals. The factor for production of female flowers was designated S f and the factor for hermaphroditism S h Table 1 and it was proposed that S f is recessive to S h. Furthermore, no male plants resulting from crosses were found.

They selected, at random, some F1 plants and crossed them with a homozygous female Vitis. The allele Su F represses the development of functional female organs and the allele Su m , in homozygous condition, suppresses the development of male organs.

In a study in which several hermaphrodite varieties of vinifera were self-pollinated some interesting observations were found Bronner, : 1 some hermaphrodite varieties were heterozygous for the sex locus resulting ratio of hermaphrodites and females , 2 one variety was homozygous resulting in only hermaphrodite plants , and 3 the variety Muscat Ottonel when self-pollinated resulted in a F1 with a surprising high number of male individuals Bronner, These observations showed in the two closed loci model occasionally crossing-over might occur depending on the variety in study or that a more complex model might be needed to explain Vitis flower type segregation.

However, is worth to notice that male offspring between hermaphrodites plants were only observe in two different crosses involving four different varieties of which the result offspring from self-pollination is unknown. Therefore, this model has not been tested so far. Instead, the segregation patterns observed in the majority of studies of sex inheritance and recent studies on sex determinism markers appear to support Valleu, Oberle and Antcliff models Antcliff, ; Avramov et al.

Wild vines of V. There are two sources of hermaphroditism in muscadinia , named H1 and H2. The H1 hermaphrodite plant was achieved through the cross of the muscadinia female variety Eden and the male variety Mission Male while the H2 hermaphrodite was the result of the cross between the female Scuppernog and the male New Smyrna.

These two hermaphrodite plants are the origin of hermaphrodite V. However the H2 plant when self-pollinated originates hermaphrodite, female and male plants in a ratio Conner et al. RNA-Seq studies on vinifera and sylvestris male and female uncovered some genes, whose functionally characterised homologues were previously described to be involved in flower development and organ development, displaying differential expression between male, female and hermaphrodite flower development Ramos et al.

These genes belong to several functional categories and seem to be distributed throughout the 19 grapevine chromosomes. Arabidopsis thaliana mutants for LAP3 show induced pollen sterility or abnormal exine patterns Dobritsa et al. Also, in A. Furthermore, mutant plants for ACOS5 do not produce pollen in late stage of stamens development, as the pollen wall lacks sporopollenin or exine and its formation is thus compromised Dong et al.

AtCalS5 , which codes for a protein responsible for depositing callose at microspores, is essential for correct exine formation in the pollen, and knockout mutants for CalS5 resulted in reduced fertility Dong et al. However, as a whole, the above experiments result in either the absence or defective expression of these genes. In female sylvestris the opposite was observed, with the transcripts being highly expressed at late flower development. The effect of over-expression of these genes has not yet been studied, nevertheless, the results might suggest that excess of sporopollennin and exine deposition could result in infertile pollen.

A large deposition of these pollen wall elements might lead to small and oval pollen grains lacking pores Gallardo et al. In sylvestris female pollen is also smaller and fewer grains are formed Gallardo et al.
