“…J. regia is native to the Middle East, whereas J. nigra is native to the eastern United States, and the lack of fertilization between such taxa as these with a history of isolation can be explained in terms of a non-functioning of the pollen-pistil recognition systems. This has been called incongruity (Haghighi and Ascher 1988;Hogenboom 1973Hogenboom , 1984, i.e., the lack of critical information in one partner about aspects of the other due to the absence of opportunity for co-evolution of male gametophytes and pistils (Ascher 1986).…”

Summary. The Juglans regia • Juglans nigra hybrid cannot be obtained because of stable interspecific barriers. We have analyzed and described various morphological and biochemical characters in J. regia and J. nigra pollen: differences in the mineral composition, polysaccharide reserves, wall ultrastructure and protein pattern of soluble cytoplasm, membranes, and cell-wall fractions. The absence of a glycoprotein fraction in the wall of J. nigra suggests that the regulation of critical steps in the interspecific matching with female tissues could be affected.

“…This phenomenon has been proposed to occur from a lack of genetic information in one of the partners of a given genotypic combination about either the structure or the physiology of the other partner (Hogenboom 1973), or for pistil recognition of pollen with a foreign origin (Kermicle and Evans 2010). CI can be either unilateral or bilateral, depending on whether a given genotypic combination is, respectively, compatible in only one direction or in both directions of the cross.…”

Knowledge of internal hybridization barriers is relevant for germplasm conservation and utilization. The two pre-zygotic barriers are pollen–pistil self-incompatibility (SI) and cross-incompatibility (CI). To ascertain whether SI and CI were phenotypically related phenomena in potatoes, extensive intra- and interspecific, both intra- and interploidy breeding relationships were established, without previous assumptions on the compatibility behavior of the studied germplasm. Pollen–pistil relationships were analyzed at the individual genotype/accession/family level. In two seasons, 828 intra- and interspecific genotypic combinations were performed, using accessions of the wild potatoes Solanum chacoense Bitter (2n = 2x = 24), S. gourlayi Hawkes (2n = 2x = 24; 2n = 4x = 48), and S. spegazzinii Bitter (2n = 2x = 24), full-sibling (hereinafter “full-sib”) families (2n = 2x = 24) within/between the latter two diploids, and S. tuberosum L. (2n = 4x = 48) cultivars. Pollen–pistil incompatibility occurred in the upper first third of the style (I1/3) in all selfed diploids. In both the intra- and interspecific combinations, the most frequent relationship was compatibility, followed by I1/3, but incompatibility also occurred in the stigma and the style (middle third and bottom third). We observed segregation for these relationships in full-sib families, and unilateral and bilateral incompatibility in reciprocal crosses between functional SI genotypes. Cross-incompatibility in potatoes is, apparently, controlled by genes independent of the S-locus or its S-haplotype recognition region (although molecular evidence is needed to confirm it), with segregation even within accessions.

“…The successful completion of a series of sequential events following pollination requires a perfect blend of co-ordination between genes and gene complexes of pollen and the ovule parents (Hogenboom 1973). The present investigation was mainly focused on the rate of pollen tube growth and structural abnormalities of alien pollen on the cultivated pistils to understand how the reproductive isolation barriers operate on pollen tube pene-2008 tration in different stages of pistils.…”

Pollen Pistil Interaction in Inter-Specific Crosses of Vigna sp.

Summary Inter-specific hybridization is mainly used to introgress pest and disease resistant genes. Vigna radiata and Vigna mungo are widely cultivated and consumed in India. These crops are highly affected by Mungbean Yellow Mosaic Virus (MYMV) disease and bruchid (Callasobruchus spp.) pest, leading to heavy yield loss. Vigna umbellata, a divergent Vigna species is found to be resistant to both MYMV and bruchids. Utilization of this species to introgress the resistance gene is marginal because of their inherent low crossability with the cultivated Vigna species. In the present study, V. umbellata was used as pollen donors in hybridization with V. radiata and V. mungo. Low percentage of pod set observed in the cross V. radiataϫV. umbellata (12.89%) and V. mungoϫV. umbellata (5.56%) indicated the presence of reproductive barriers that render introgression difficult. Aim of this study was to observe pre-fertilization barriers operating in V. radiataϫV. umbellata and V. mungoϫV. umbellata crosses. In vivo pollen germination and growth of pollen tubes were studied in inter-specific crosses using fluorescence microscope. The pollen grain germination on stigmatic surface was normal. A very common pre-fertilization barrier of slow rate of pollen growth, in addition to structural abnormalities in stigmatic and stylar regions was observed in both the crosses. However, the level of incompatibility was high in V. mungoϫV. umbellata cross than V. radiataϫV. umbellata. Measures to overcome incompatibility barriers before fertilization in these crosses to produce interspecific hybrids are discussed.
