Synteny analysis in Rosids with a walnut physical map reveals slow genome evolution in long-lived woody perennials. [PDF]

, 2015
BackgroundMutations often accompany DNA replication. Since there may be fewer cell cycles per year in the germlines of long-lived than short-lived angiosperms, the genomes of long-lived angiosperms may be diverging more slowly than those of short-lived ...

Expression and trans-specific polymorphism of self-incompatibility RNases in Coffea (Rubiaceae) [PDF]

, 2011
Self-incompatibility (SI) is widespread in the angiosperms, but identifying the biochemical components of SI mechanisms has proven to be difficult in most lineages. Coffea (coffee; Rubiaceae) is a genus of old-world tropical understory trees in which the

Revision of Manettia (Rubiaceae) in Paraguay

Nordic Journal of Botany, EarlyView.
Manettia Mutis is a Neotropical genus comprising over 100 species, many of which are only known from their original descriptions or, at most, from revisions dating back over 100 years. Recent review studies have remained unpublished for several years. Conventional taxonomic methods are followed.
