Different processes shape the patterns of divergence in the nuclear and chloroplast genomes of a relict tree species in East Asia

Ecology and Evolution, Volume 10, Issue 10, Page 4331-4342, May 2020., 2020
We infer that different markers reflecting divergent processes may owe to the heredity and ploidy difference of genomes, while divergent extent of significant patterns in northern and southern regions may owe to different population history between regions.

Fertility of Vriesea gigantea Gaud. (Bromeliaceae) in southern Brazil [PDF]

American Journal of Botany, 2007
Plant fertility is a central subject of many questions in plant evolutionary and conservation biology. Pollen availability, abiotic resources, and flowering pattern can limit fruit and seed production. Open pollination and pollen supplementation studies are used to estimate any pollen limitation in natural populations.

Phyllotaxis: is the golden angle optimal for light capture?

New Phytologist, Volume 225, Issue 1, Page 499-510, January 2020., 2020
Summary Phyllotactic patterns are some of the most conspicuous in nature. To create these patterns plants must control the divergence angle between the appearance of successive organs, sometimes to within a fraction of a degree. The most common angle is the Fibonacci or golden angle, and its prevalence has led to the hypothesis that it has been ...

Conservation of Vriesea flammea L.B.Sm., an endemic Brazilian bromeliad: effects of nutrients and carbon source on plant development.

Brazilian journal of biology = Revista brasleira de biologia, 2020
Bromeliaceae is restricted to the Neotropical region and has a high degree of endemism, which contributes to increased biodiversity because of the diverse morphological characteristics of individuals.
