  author={Charles A. Knight and Rachel B. Clancy and Lars G{\"o}tzenberger and LeightonG. Dann and JeremyM. Beaulieu},
Here we test whether genome size is a predictor of pollen size. If it were, inferences of ancient genome size would be possible using the abundant paleo-palynolgical record. We performed regression analyses across 464 species of pollen width and genome size. We found a significant positive trend. However, regression analysis using phylogentically independent contrasts did not support the correlated evolution of these traits. Instead, a large split between angiosperms and gymnosperms for both… CONTINUE READING
