The phylogeny and timescale of life are becoming better understood as the analysis of
genomic data from model organisms continues to grow. As a result, discoveries are being …

Covering: 1993–2004Lycopodium alkaloids are quinolizine, or pyridine and α-pyridone type
alkaloids. Some Lycopodium alkaloids are potent inhibitors of acetylcholinesterase (AChE) …

Green plants (Viridiplantae) include around 450,000–500,000 species, of great diversity and
have important roles in terrestrial and aquatic ecosystems. Here, as part of the One …

Establishing the timescale of early land plant evolution is essential for testing hypotheses on
the coevolution of land plants and Earth's System. The sparseness of early land plant …

The evolutionary emergence of land plant body plans transformed the planet. However, our
understanding of this formative episode is mired in the uncertainty associated with the …

Reconstructing the origin and evolution of land plants and their algal relatives is a
fundamental problem in plant phylogenetics, and is essential for understanding how critical …

Premise of the Study For the past one billion years, green plants (Viridiplantae) have
dominated global ecosystems, yet many key branches in their evolutionary history remain …

Background Next-generation sequencing has provided a wealth of plastid genome
sequence data from an increasingly diverse set of green plants (Viridiplantae). Although …

Rates of molecular evolution vary widely between lineages, but quantification of how rates
change has proven difficult. Recently proposed estimation procedures have mainly adopted …

Premise of the Study Phylogenetic support has been difficult to evaluate within the green
plant tree of life partly due to a lack of specificity between conflicted versus poorly informed …
