DUPLICATION HIERARCHY. "Whole-genome duplications happen repeatedly in a typical flowering plant lineage. Following most ancient tetraploidies, the two subgenomes are distinguishable because one subgenome, the dominant subgenome, tends to have more genes than the other subgenome. Additionally, among retained pairs, the gene on the dominant subgenome tends to be expressed more than its recessive homeolog." https://lnkd.in/bCmw3Fr View in LinkedIn

GENOME DOMINANCE. "Ancient plant polyploids contain dissimilar subgenomes. Subgenomes that have lost fewer genes are subgenomes that tend to express their genes to higher mRNA levels: “genome dominance.” Genome dominance is heritable through multiple rounds of polyploidy and over tens of millions of years." https://lnkd.in/bCmw3Fr View in LinkedIn

SIZE CONSTRAINTS. "This study presents a new step toward resolving the paradoxical relationship between average genome size and ploidy level in angiosperms, suggesting that constraints on maximum genome size and maximum monoploid number for WGDs, and not only genome downsizing, limit angiosperm genome sizes in the face of frequent WGDs." (WGD = whole genome duplication). https://lnkd.in/bCmw3Fr View in LinkedIn

NUTRITIONAL ASPECTS. "A species with a large genome size might require a large supply of nutrients (e.g., phosphorus), preventing its establishment in nutrient-limited environments. Thus, there may be selection against duplicating genome sizes in species with especially large content." https://lnkd.in/bCmw3Fr View in LinkedIn

SIZE IMPEDIMENT. "Plants with large genomes may have low speciation rates, are not well adapted to extreme environments, and have low maximum photosynthetic rates." https://lnkd.in/bCmw3Fr View in LinkedIn

SUPPRESSION OF TRANSPOSABLE ELEMENTS. "Almost all species contain mechanisms to silence TEs. TE insertion precedes the smRNA mechanisms that silence TEs." (TE = transposable element). https://lnkd.in/bCmw3Fr View in LinkedIn
