A virus-induced gene-silencing system for functional genetics in a betalainic species, (Amaranthaceae).

Premise Of The Study: Research in Amaranthaceae could be accelerated by developing methods for targeted gene silencing. Most amaranths, including , produce betalains. However, the physiological and ecological roles of these pigments are uncertain.

Partitioning genetic and species diversity refines our understanding of species-genetic diversity relationships.

Disentangling the origin of species-genetic diversity correlations (SGDCs) is a challenging task that provides insight into the way that neutral and adaptive processes influence diversity at multiple levels. Genetic and species diversity are comprised by components that respond differently to the same ecological processes. Thus, it can be useful to partition species and genetic diversity into their different components to infer the mechanisms behind SGDCs.
