RESUMEN
The cut chrysanthemum holds one of the most substantial segments of the global floriculture market, particularly in Korea. We conducted a detailed assessment of the genetic structures across the cut chrysanthemum breeding lines in Korea. Using standard and spray chrysanthemum breeding lines from leading Korean research institutes, we first compared the variability of 12 horticultural traits, revealing a wide range of variation for most traits. We found that the overall flower diameter (OFD) and ray floret length (RFL) showed a solid positive relationship, regardless of the type. From a multivariate approach, OFD, RFL, and ray floret width (RFW) show consistently high association. Genotypic and phenotypic coefficients of variation analyses further indicated the significant genetic control over most traits. However, certain traits, like the volume of flowers (VF) in standard types, are more influenced by environments. Lastly, our analysis demonstrated substantial variability in broad-sense heritability (H); plant height (PH) consistently showed high H in both types. But the number of side branches (NOSB) and VF exhibited inconsistent H scores. These findings highlight the need for type-specific breeding strategies and modulating environmental management to optimize the trait expressions depending on the H scores, which offers significant implications for future breeding strategies.
RESUMEN
Fusarium oxysporum f. sp. lactucae 016-086 is a plant pathogenic filamentous fungus isolated from wilted lettuce in Korea. We reported complete mitochondrial genome sequence of F. oxysporum f. sp. lactucae 016-086. Total length of this mitogenome is 41,826 bp and it encoded 42 genes (14 protein-coding genes, 2 rRNAs, and 26 tRNAs). Nucleotide sequence of coding region takes over 30.6%, and overall GC content is 32.5%. Phylogenetic tree of Fusarium mitochondrial genomes presented distinct clades along with nine formae speciales. This mitogenome will contribute distinguishing formae speciales of F. oxysoporum claearly with additional mitogenomes sequenced in the near future.
RESUMEN
Fusarium oxysporum is a famous plant pathogenic filamentous fungus. Here, we report the complete mitochondrial genome sequence of F. oxysporum f. sp. lactucae isolated from the lettuce field in Suwon area, Korea. Total length of the mitochondrial genome is 45,020 bp and it encodes 42 genes (15 protein-coding genes, two rRNAs, and 25 tRNAs). Nucleotide sequence of coding region takes over 32.7%, and overall GC content is 32.4%. Phylogenetic tree presented that F. oxysporum f. sp. lactucae 09-002 was clustered with Fusarium commune not like another F. oxysporum mitochondrial genomes, requiring further analyses.
