“…This idea is compatible with the 'large-genome-constraint' hypothesis, which postulates that large genomes might be maladaptive (Vinogradov, 2003;Knight et al, 2005). For example, large-genomed plants are restricted to having large seeds (Knight & Ackerly, 2002;Beaulieu et al, 2007;Carta et al, 2022) and stomata (Beaulieu et al, 2008;Veselý et al, 2012) because a larger genome occupies more volume (Cavalier-Smith, 2005). Large seeds and stomata might limit species' dispersal ability (Sonkoly et al, 2017) and narrow their ecological niche, as large stomata are detrimental in drier conditions (Veselý et al, 2020), leading to smaller geographical ranges (Sheth et al, 2020).…”

(1) Evolution of genome size is shaped by various intrinsic and extrinsic factors. We explored three long-standing hypotheses concerning factors shaping the global distribution of genome size: the mutational hazard hypothesis, the polyploidy-mediated hypothesis and the climate-mediated hypothesis. (2) We compiled the largest genome size dataset to date, encompassing >5% of known angiosperm species and analyzed genome size distribution using a comprehensive geographic distribution dataset for all angiosperms across all continents. (3) Angiosperm species with large range sizes only have small genomes, consistent with the mutational hazard hypothesis. We also uncovered a unique latitudinal pattern in the distribution of genome size diversity. Climate had a strong effect on the latitudinal pattern in genome size, while the effect of polyploidy was small. Contrary to the unimodal latitudinal patterns found for plant size traits and polyploidy, the increase in angiosperm genome sizes from the equator to 40-50 degrees N/S is probably mediated by different (mostly climatic) mechanisms from those underpinning the decrease in genome sizes observed from 40-50 degrees northwards. (4) Overall, our global analyses highlight that species range size and climate factors are the main drivers shaping the global distribution of angiosperm genome sizes, with their relative importance varying across the latitudinal gradient.

The abundance of plant genomic information caused by the decrease of sequencing costs contrasts with the lack of databases that integrate genome annotation, taxonomy and phenotypes to produce statistically sound, biologically meaningful knowledge. Here we present ARCADE (ARChaeplastida Annotation DatabasE), a database of 171 high-quality archaeplastidian non-redundant proteomes gathered from six primary genomic databases, together with proteome quality metrics and a growing number of associated metadata. As a case study to demonstrate the usefulness of ARCADE, we used it to investigate the expansion and contraction of protein domains associated with the evolution of genome size (hereafter GS). GS varies greatly among land plants and the synthesis of large genomes can be costly to cells. Although GS has been studied extensively for decades, the molecular mechanisms involved in the adaptations of plants to the increase in GS are still poorly understood. We used the annotation and phylogenetic information available in ARCADE, together with estimated GS values available for 83 land plant species, to search for associations between the abundance of protein domain families in these species and GS variation through phylogenetic-aware methods. Additionally, we estimated the GS for the ancestral nodes of the extant land plant species. GS seems to be decreasing along the course of evolution, except for a few branches that might have undergone independent GS increases. We found 7 Pfam correlated with the variation in GS in land plants, mainly related to nucleotide metabolism, DNA repair and genome organization. We found larger genomes to have a greater frequency of the Histone 2A superfamily, responsible for diverse functions, including the nucleosome formation and silencing of transposable elements. These molecular functions we found correlated to GS variation suggests they may be associated with preserving genome stability in larger genomes, and might indicate the evolution of mechanisms to cope with the variation in GS in land plants.

“…In contrast, Meagher et al [ 18 ] found that DNA content was again negatively correlated with flower size. Angelino et al [ 19 ] indicated a positive correlation between genomic C-value and seed quality in angiosperms. Korban et al [ 20 ] determined the genomic C-value of 100 apple germplasm and showed that genomic C-value and stomatal length were positively correlated.…”

Chinese jujube (Ziziphus jujuba Mill.) originated in the Yellow River basin (YRB) of the Shanxi–Shaanxi region. The genomic C-value is a crucial indicator for plant breeding and germplasm evaluation. In this study, we used flow cytometry to determine the genomic C-values of jujube germplasms in the YRB of the Shanxi–Shaanxi region and evaluated their differences in different sub-regions. Of the 29 sub-regions, the highest and lowest variations were in Linxian and Xiaxian, respectively. The difference between jujube germplasms was highly significant (F = 14.89, p < 0.0001) in Linxian. Cluster analysis showed that both cluster 2 and 4 belonged to Linxian, which were clearly separated from other taxa but were cross-distributed in them. Linxian County is an important gene exchange center in the YRB of the Shanxi–Shaanxi region. Principal component analysis showed that cluster 1 had low genomic C-values and single-fruit weights and cluster 2 had high genomic C-values and vitamin C contents. The genomic C-value was correlated with single-fruit weight and vitamin C content. In addition, the genomic C-value was used to predict fruit agronomic traits, providing a reference for shortening the breeding cycle and genetic diversity-related studies of jujube germplasm.
