“…The genome size of A. konjac estimated by the 17-mer depth distribution analysis was 5.67 Gb ( Supplementary Fig. 1 , Supplementary Table 2 ), which was somewhat smaller than estimates by previous flow cytometry analysis (approximately 6.33 Gb) [19] . And the heterozygosity estimated was around 0.96% ( Supplementary Table 2 ).…”

“…However, the Araceae family which comprises a large number of diverse species with huge differences in genome sizes [18] . For example, Spirodela polyrhiza is an aquatic plant with a genome size of only 158 Mb, while species of other genera, such as Colocasia and Amorphophallus , have relatively larger genomes (2.40 Gb–15.48 Gb) [19] , [20] . As the chloroplast only provides information on the unilateral inheritance, the genome data is more accurate in inferring evolutionary history of species.…”

“…The new data were combined with the C-values from the RBGK database ( Supplementary Table S1 ) and for the terrestrial Amorphophallus konjac with the value measured by Zhao et al [ 30 ]. As there are some discrepancies between the genus and species names of plants in the RBGK database and the current taxonomy [ 18 , 31 , 32 ], we matched 18 synonyms with their current valid taxonomic status ( Supplementary Table S2 ).…”

The genome size of an organism is an important trait that has predictive values applicable to various scientific fields, including ecology. The main source of plant C-values is the Plant DNA C-values database of the Royal Botanic Gardens Kew, which currently contains 12,273 estimates. However, it covers only 2.9% of known angiosperm species and has gaps in the life form and geographic distribution of plants. Only 4.5% of C-value estimates come from researchers in Central and South America. This study provides 41 new C-values for the aroid family (Araceae), collected in the Piedras Blancas National Park area in southern Costa Rica, including terrestrial, epiphytic and aquatic life forms. Data from our study are combined with C-value entries in the RBGK database for Araceae. The analysis reveals a wider range of C-values for terrestrial aroids, consistent with other terrestrial plants, a trend toward slightly lower C-values for epiphytic forms, which is more consistent for obligate epiphytes, and comparatively low C-values for aquatic aroids.

“…The hydrolysate GMH of KGM can prolong lifespan by regulating intestinal proliferation homeostasis [3,4]. With the increase in understanding of 2 of 19 KGM and its derivatives, the benefits of KGM in humans have been gradually elucidated, and KGM has therefore received extensive attention from researchers [5,6]. A. bulbifer is resistant to soft rot, has multiple leaf relay growth habits and has a high yield.…”

The flowering of Amorphophallus bulbifer (A. bulbifer) plays an important role in its reproduction. The flowers and leaves of A. bulbifer cannot grow at the same time. However, the physiological and molecular mechanisms involved in flower bud and leaf bud formation are still unclear. In this study, the flower buds and leaf buds of A. bulbifer in the early stage of growth were used as research materials, transcriptome and metabolome analyses were carried out, and the soluble sugar and starch contents of A. bulbifer corms were determined. Transcriptome analysis revealed 5542 differentially expressed genes (DEGs) between flower buds and leaf buds, 3107 of which were upregulated and 2435 of which were downregulated. Enrichment analysis of the KEGG pathway showed that these differential genes were enriched mainly in the plant hormone signal transduction, DNA replication and fatty acid elongation pathways. A total of 5296 significant differentially abundant metabolites were screened out by nontargeted metabolomics analysis. The differentially abundant metabolites were functionally classified in the HMDB, and 118 were successfully matched, including 17 that were highly expressed in flower buds. The differentially abundant metabolites in the flower buds were mainly enriched in pathways such as amino acid metabolism, isoquinoline alkaloid biosynthesis and pyrimidine metabolism. Targeted metabolomics analysis revealed that the contents of ABA, ZT and iPA in flower buds were significantly greater than those in leaf buds, while the opposite trend was observed for IAA. The analysis of soluble sugar and starch contents showed that the starch and soluble sugar contents in flower buds were significantly greater than those in leaf buds. The results of this study showed that flower bud development in A. bulbifer was regulated by amino acids, starch, ABA, ZT, iPA, IAA and other hormones. These findings could lead to valuable genetic resources for further study of A. bulbifer flowering and provide a deeper understanding of the molecular basis of A. bulbifer flowering.
