How genome size variation is linked with evolution within Chenopodium sensu lato
Original language description
Results can be summarized as follows: (1) We reportthe first chromosome counts for five Chenopodium species. (2) Flow cytometry determined that 2C and 1CxDNA values differed up to 7.83- and 3.60 fold, respectively, with the lowest 1Cx value for C. schraderianum(0.412 pg) [excluding tetraploid (2n = 4 x = 32) C. ambrosioides with x = 8 and 1Cx DNA content 0.279 pg]and the highest for C. californicum (1.484 pg). (3) Our extended phylogeny confirms the existence ofpreviously recognized basic evolutionary lineages while underscoring the need to further increase taxonsampling for a full understanding of relationships in Chenopodioideae. (4) Our analysis of genome sizeevolution estimated the ancestral genome size of Chenopodium s. lat. at 0.541 pg/1Cx. In addition, the datarevealed a correlation between 1Cx DNA content and ploidy level. Moreover, the PGLS approach indicatedthat the genome size variation (i) followed the random walk model, indicating no unambiguous trendtowards genome size increase or decrease; (ii) was correlated with phylogeny (0.987); (iii) evolvedgradually (2.256); and (vi) occurred rather late after speciation, which can be attributed to species-specific adaptation (3.000). (5) There are indications that several ecological traits were significantlyassociated with 2C DNA content. While mean plant height, maximum plant height, fruit diameter and lifeform were positively correlated with genome size, the species’ continent of origin showed no correlation.
