The megaherbivore gap after the non-avian dinosaur extinctions modified trait evolution and diversification of tropical palms

Renske E. Onstein et al.

Summary: The extinction of non-avian dinosaurs in the Cretaceous-Palaeogene period led to a 25 million year gap in megaherbivores, which had significant consequences for plant diversification and trait evolution. By studying palms, researchers found that this gap was characterized by slower speciation, decreased evolution of defensive traits, and increased evolution of large fruits. The absence of browsing by megaherbivores led to a loss of defence traits, but did not result in a loss of large fruits, which may be explained by rising temperatures and the subsequent radiation of seed-dispersing birds and mammals.

Correlated evolution of seed mass and genome size varies among life forms in flowering plants

Angelino Carta et al.

Summary: Seeds and genome sizes show evolutionary correlation influenced by life forms in angiosperms. Different life forms have different optimal values and covariance relationships for seed mass and genome size evolution. The strongest evolutionary correlation between seed mass and genome size is found in annuals, serving as an adaptation to complete their life cycle quickly under favorable environmental conditions.

Genomic innovation and regulatory rewiring during evolution of the cotton genus Gossypium

Maojun Wang et al.

Summary: In this study, we constructed a pan-genome of the Gossypium genus and explored the impact of transposon amplification on genome composition and evolution. We found evolutionary connections between genome size variation, chromatin structure reorganization, and chromatin interactome rewiring, as well as identified regulatory variations underlying fiber length in cotton. Our findings provide insights into the evolution of genome organization and regulation, and can inform cotton improvement strategies.

Polyploidy increases storage but decreases structural stability in Arabidopsis thaliana

Evan K. Pacey et al.

Summary: Whole-genome duplication, leading to polyploidy and endopolyploidy, is widespread in the tree of life. Increased cell size following genome duplication can increase plant storage capacity and tolerance to resource limitation, but incurs biomechanical costs. The functional consequences of autopolyploidy can vary with accession identity, suggesting potential for adaptation following whole-genome duplication.

The ecology of palm genomes: repeat-associated genome size expansion is constrained by aridity

Rowan J. Schley et al.

Summary: The size of a plant's genome plays a significant role in its evolution and adaptation to the environment. The diversity in genome size can be attributed to the expansion of repetitive elements, and the dynamics of these repeat 'communities' are influenced by environmental stressors, particularly aridity.

Dependence of the Duration of Periods of the Mitotic Cycle on the Holoploid DNA Content in Root Apical Meristems

N. V. Zhukovskaya et al.

Summary: The dependence of the duration of individual periods of the mitotic cycle on DNA content, chromosome number, and DNA amount per chromosome was analyzed in 64 species. The duration of the mitotic cycle and its periods in diploids increased with haploid DNA content, while polyploid species showed weak dependence on DNA content for the duration of mitosis. The correlation was more pronounced in certain species from the Asparalales and Liliales orders.

Genome size evolution is associated with climate seasonality and glucosinolates, but not life history, soil nutrients or range size, across a clade of mustards

N. Ivalu Cacho et al.

Summary: Climate seasonality and glucosinolate compounds are positively associated with genome size, while life history, geographic range size, or soil nutrients do not have a significant impact on genome size in this clade of Brassicaceae.

Maximum CO2 diffusion inside leaves is limited by the scaling of cell size and genome size

Guillaume Theroux-Rancourt et al.

Summary: Genome size plays a crucial role in determining the sizes and packing densities of cells in leaf tissues, which in turn affect CO2 diffusion. Smaller cells enable more mesophyll surface area to be packed into the leaf volume, facilitating higher CO2 diffusion. Additionally, the spongy mesophyll layer facilitates gaseous phase diffusion while the palisade mesophyll layer facilitates liquid-phase diffusion.

Exploring environmental selection on genome size in angiosperms

Lubna Faizullah et al.

Summary: Despite the frequency of polyploidy and repeat amplification in the ancestries of most lineages, most angiosperm species have small genomes. Increased genome size may incur costs impacting minimum cell size, photosynthesis, water-use efficiency, and nucleus demands, leading to more severe trade-offs. Species with smaller genomes may be favored under stressed conditions, suggesting implications for ecological and evolutionary dynamics.

Genome size variation in Cactaceae and its relationship with invasiveness and seed traits

Sara Lopes et al.

Summary: Genome size is not a reliable predictor of invasiveness in Cactaceae, as no significant differences were observed in genome size among categories of invasion. Additionally, there were no correlations between genome size and studied seed traits across the whole dataset, with different correlations observed at a finer scale within subfamilies and tribes. The large number of genome size estimates reported in this study provides significant opportunities for further research on the evolution of genome size in Cactaceae and possible correlations with geographical, environmental, and phenotypic traits.

Genome Size Covaries More Positively with Propagule Size than Adult Size: New Insights into an Old Problem

Douglas S. Glazier

Summary: The amount of genetic material in cell nuclei is more closely related to egg size than body size in crustaceans, indicating a strong correlation between genome size and cell size. The mismatch between physical structure and genetic information in organisms may be due to variable accumulation of repetitive DNA sequences. Relationships between genome size and body size are weaker in larger organisms where body size is linked more to cell multiplication than cell enlargement.

Genome downsizing after polyploidy: mechanisms, rates and selection pressures

Xiaotong Wang et al.

Summary: The analysis of over 10,000 plant genome sizes suggests that most species have smaller genomes than expected given the incidence of polyploidy in their ancestries. The rate of DNA loss following polyploidy is likely to have been very low, raising the question of how such small DNA losses can be visible to selection and drive genome downsizing. Various hypotheses are explored to explain how selection might favor genome downsizing following polyploidy.

Polyploidy: an evolutionary and ecological force in stressful times

Yves Van de Peer et al.

Summary: Polyploidy is hypothesized to play a role in both evolutionary dead-ends and diversification. Research suggests that whole-genome duplications may be linked with extinction events or global changes, while polyploids thrive in harsh environments. Biotic interactions, particularly with pathogens or mutualists, have differing effects on polyploids compared to nonpolyploids. Stress response is identified as a key factor in the establishment and success of polyploidy.
