“…Because virtually all of the zygote cytoplasm is contributed by the egg, the differences between reciprocal hybrids can be used to identify CF phenotypes that develop under the influence of maternal factors. Although often employed to study phenotypic differences in plants (Erickson et al, 1990; Song et al, 1993; Stanton, 2005, Lain et al, 2016) or genetic imprinting (Feil and Berger, 2007; Wolf et al, 2014), reciprocal hybridization has only rarely been used to study the evolutionary origin of novelties within a single species (Marshak, 1936; Zakas and Rockman, 2014).…”

The role of maternal factors in the evolution of development is poorly understood. Here we describe the use of reciprocal hybridization between the surface dwelling (surface fish, SF) and cave dwelling (cavefish, CF) morphs of the teleost Astyanax mexicanus to investigate the roles of maternal genetic effects in cavefish development. Reciprocal hybridization, a procedure in which F1 hybrids are generated by fertilizing SF eggs with CF sperm (SF × CF hybrids) and CF eggs with SF sperm (CF × SF hybrids), revealed that the CF degenerative eye phenotype showed maternal genetic effects. The eyes of CF × SF hybrids resembled the degenerate eyes of CF in showing ventral reduction of the retina and corresponding displacement of the lens within the optic cup, a smaller lens and eyeball, more lens apoptosis, a smaller cartilaginous sclera, and lens-specific gene expression characteristics compared to SF × CF hybrids, which showed eye and lens gene expression phenotypes resembling SF. In contrast, reciprocal hybridization failed to support roles for maternal genetic effects in the CF regressive pigmentation phenotype or in CF constructive changes related to enhanced jaw development. Maternal transcripts encoded by the pou2f1b, runx2b, and axin1 genes, which are involved in determining ventral embryonic fates, were increased in unfertilized CF eggs. In contrast, maternal mRNAs encoded by the ß-catenin and syntabulin genes, which control dorsal embryonic fates, showed similar expression levels in unfertilized SF and CF eggs. Furthermore, maternal transcripts of a sonic hedgehog gene were detected in SF and CF eggs and early cleaving embryos. This study reveals that CF eye degeneration is controlled by changes in maternal factors produced during oogenesis and introduces A. mexicanus as a model system for studying the role of maternal changes in the evolution of development.

“…The success of interspecific hybridization and the barriers encountered while achieving this success are the subject of research by breeders and researchers. For many ornamental plants interspecific hybridization has been pursued such as Begonia (Siregar, 2016), Delphinium (Cheng et al, 2020), Dianthus (Dewanti et al, 2019), Eustoma (Barba-Gonzalez et al, 2017), Gentiana (Takamura et al, 2019), Hibiscus (Kuligowska et al, 2016a), Iris (Lian et al, 2016), Nymphaea (Sun et al, 2018), Phalaenopsis (Rungruchkanont and Promchot, 2016), Rosa (Farooq et al, 2016), Tagetes (He et al, 2016), Tulipa (Xing et al, 2020), Vibirnum (Xie et al, 2017) and Viola (Żabicka et al, 2020).…”

Kalanchoë cultivars rank as one of the most sold potted ornamental plants in the world. Among its key features that sustain high market interest are the long flowering period, abundance of flowers, thick and glossy leaves, easy maintenance and less water requirement compared to other potted plants. In breeding studies of Kalanchoë, plants with different flower colors such as white, cream, yellow, orange, red, pink and purple were developed. Moreover, double-flowered cultivars (comprising a large number of petals), more compact and cultivars with larger flowers were also obtained. Novel morphological characteristics are always in high demand in the market of ornamental plants. Increasing the variation in the gene pool with different species played a major role in the development of these characteristics. Nowadays, not only potted cultivars are launched but also cut flower cultivars have been developed and presented to consumers. Besides conventional breeding and interspecific hybridization, biotechnological methods, which have a promising future, are used to develop morphological characteristics of Kalanchoë.

“…Its individual flowers stay open for about 4 h in form the late afternoon to the early evening (Luo et al, 2016). To improve its flower colour and flowering time, interspecific crosses were conducted to introgress useful genes from I. domestica to I. dichotoma and this has resulted in some novel varieties (Yang et al, 2013;Lian et al, 2016;Ruan et al, 2017;Xu et al, 2017;Gao et al, 2020). Previous studies concentrated on violet and white-flowered I. dichotoma plants (Chimphamba, 1973;Ruan et al, 2017), whereas I. dichotoma with yellow flowers has not been comprehensively investigated.…”

Pollen characteristics are very important for Iris interspecific hybridisation. In this study, the pollen viability and male meiosis were studied in yellow-flowered Iris dichotoma (Y2), I. domestica (S3) and their hybrids F1, F2 and BC1 (BC1-Y and BC1-S). The BC1-Y hybrids showed higher pollen viability than that of F1, F2 and BC1-S hybrids, which were between I. dichotoma (26.1%) and I. domestica (35.1%). Two sterile hybrids, F2-1 and BC1-S-1, exhibited more meiotic abnormalities (57.3% and 58.7%) than other individuals. During the first meiotic division, a diffuse diplotene stage was observed for the first time in the genus Iris. The meiotic abnormalities included non-congressed chromosomes, chromosome bridges, lagging chromosomes, unequal division, abnormally oriented spindle fibres, nonsynchronous division and polyad, and resulted in reduced pollen fertility. The relatively high frequency of 2n pollen grains was found in hybrids of BC1-Y-2, BC1-Y-1, BC1-S-2, BC1-S-3 and BC1-S-4. Our research provides a new resource for meiotic behaviour and pollen fertility of the genus Iris.
