Special Issue Information

Dear Colleagues,

Ornamental plants play an important role in human life due to their high aesthetic value. Many plant species have been introduced by plant breeders for different purposes such as garden or home improvement, the prevention of soil erosion, or their pleasing aromas. Ornamentals currently comprise thousands of plant species encompassing a wide range of different types, including cut flowers, bedding plants, hanging plants, potted plants, shrubs, turf, ornamental trees, and aquatic plants.

With increased market demand for novel ornamental phenotypes, ornamental plant breeders are perpetually challenged to develop unique and increasingly attractive varieties. However, many of the important traits in ornamental plant breeding programs are still poorly understood. It is therefore essential for breeders to recruit an array of novel genomic, bioinformatic, and phenotyping approaches for a better investigation and manipulation of important aesthetic traits in their breeding programs.

Here, we are excited to open a Special Issue on “Flower Crops Breeding: Genomics, Bioinformatics, and Phenotyping Analysis”. This Special Issue welcomes all types of original articles related with ornamental plant breeding.

Eastern redbud, Cercis canadensis L., is a popular ornamental tree in the U.S. and has flower colors of purple-type, red-type, and white-type. Most redbuds cultivars have purple-type flowers. Red-types and white-types are much less common. These unusual flower colors have become an important trait for incorporation into novel redbud cultivars. Eastern redbud seedlings require 3–5 years before blooming, making flower color selection a slow and expensive process. The ability to select seedlings for flower color type would significantly increase the efficiency of the breeding process. Redbud flower color is dominated by anthocyanin content; leaf petioles often show visible pink to purple color, indicating the potential presence of anthocyanin. In this study, anthocyanin profiles of 14 cultivars and 25 progenies of ‘Appalachian Red’ (red-type) × ‘Oklahoma’ (purple-type) were determined using HPLC. The petiole anthocyanin profiles were strongly indicative of plant flower-color types. Both peonidin-3-glucoside and malvidin-3-glucoside were dominant in petioles from all purple-type plants. In contrast, malvidin-3-glucoside was absent from petioles of red-type plants, and neither peonidin-3-glucoside nor malvidin-3-glucoside was detected among white-type cultivars. These results indicate that the presence or absence of peonidin-3-glucoside and malvidin-3-glucoside in petioles can be a physiological marker for identifying redbud flower color types. Full article

Caladiums are promising colorful foliage plants due to their unique leaf shapes and dazzling colors. Until now, over 2000 varieties of Caladium have been cultivated worldwide. The long-term natural variation and artificial selection have enriched the germplasm resources of Caladium in the market, yet have blurred its genetic background. In this study, 16 informative EST-SSR markers were used to screen 144 Caladium accessions, indicating that 16 EST-SSRs could distinguish all genotypes with a minimum cumulative identity probability (PI) of 2.0 2 × 10−15. Using the simulated annealing method, the richest genetic information was acquired at the same compression ratio. A final core of 44 accessions was selected, comprising 30.6% of the individuals and retraining more than 95% of the total genetic information. No significant differences were observed in allele frequency distributions or genetic diversity parameters between the core collection and the entire population. Cluster analysis roughly divided the core collections into four populations, where 66.7% of the private alleles were detected in Pop2. Finally, DNA molecular fingerprints of 44 core accessions were established, including barcodes and quick response (QR) code molecular identities (ID). The results will lay a theoretical foundation for identifying, preserving, and utilizing Caladium germplasm resources. Full article

Aneuploids are valuable materials of genetic diversity for genetic analysis and improvement in diverse plant species, which can be propagated mainly via in vitro culture methods. However, somaclonal variation is common in tissue culture-derived plants including euploid caladium. In the present study, the genetic stability of in vitro-propagated plants from the leaf cultures of two types of caladium (Caladium × hortulanum Birdsey) aneuploids obtained previously was analyzed morphologically, cytologically, and molecularly. Out of the randomly selected 23 and 8 plants regenerated from the diploid aneuploid SVT9 (2n = 2x − 2 = 28) and the tetraploid aneuploid SVT14 (2n = 4x − 6 = 54), respectively, 5 plants from the SVT9 and 3 plants from the SVT14 exhibited morphological differences from their corresponding parent. Stomatal analysis indicated that both the SVT9-derived variants and the SVT14-originated plants showed significant differences in stomatal guard cell length and width. In addition, the variants from the SVT14 were observed to have rounder and thicker leaves with larger stomatal guard cells and significantly reduced stomatal density compared with the regenerants of the SVT9. Amongst the established plants from the SVT9, two morphological variants containing 3.14–3.58% less mean fluorescence intensity (MFI) lost one chromosome, and four variants containing 4.55–11.02% more MFI gained one or two chromosomes. As for the plants regenerated from the SVT14, one variant with significantly higher MFI gained two chromosomes and three plants having significantly lower MFI resulted in losing four chromosomes. Three, out of the twelve, simple sequence repeat (SSR) markers identified DNA band profile changes in four variants from the SVT9, whereas no polymorphism was detected among the SVT14 and its regenerants. These results indicated that a relatively high frequency of somaclonal variation occurred in the in vitro-propagated plants from caladium aneuploids, especially for the tetraploid aneuploid caladium. Newly produced aneuploid plants are highly valuable germplasm for future genetic improvement and research in caladium. Full article
