Diverse mangroves deviate from other angiosperms in their genome size, leaf cell size and cell packing density relationships.

ABSTRACT:

Background and aims

While genome size limits the minimum sizes and maximum numbers of cells that can be packed into a given leaf volume, mature cell sizes can be substantially larger than their meristematic precursors and vary in response to abiotic conditions. Mangroves are iconic examples of how abiotic conditions can influence the evolution of plant phenotypes.

Methods

Here, we examined the coordination between genome size, leaf cell sizes, cell packing densities and leaf size in 13 mangrove species across four sites in China. Four of these species occurred at more than one site, allowing us to test the effect of climate on leaf anatomy.

Results

We found that genome sizes of mangroves were very small compared to other angiosperms, but, like other angiosperms, mangr
