For 15 years, the eukaryote Tree of Life (eToL) has been divided into five to eight major
groupings, known as 'supergroups'. However, the tree has been profoundly rearranged …

The calcium-based intracellular signalling system is used ubiquitously to couple
extracellular stimuli to their characteristic intracellular responses. It is becoming clear from …

In modern oceans, eukaryotic phytoplankton is dominated by lineages with red algal-derived
plastids such as diatoms, dinoflagellates, and coccolithophores. Despite the ecological …

Reconstructing the phylogenetic relationships that unite all lineages (the tree of life) is a
grand challenge. The paucity of homologous character data across disparately related …

Programmed cell death is a basic cellular mechanism. Apoptotic-like programmed cell death
(called apoptosis in animals) occurs in both unicellular and multicellular eukaryotes, and …

Molecular phylogenetics has revolutionized our knowledge of the eukaryotic tree of life. With
the advent of genomics, a new discipline of phylogenetics has emerged: phylogenomics …

Sexual reproduction and clonality in eukaryotes are mostly seen as exclusive, the latter
being rather exceptional. This view might be biased by focusing almost exclusively on …

A root for the archaeal tree is essential for reconstructing the metabolism and ecology of
early cells and for testing hypotheses that propose that the eukaryotic nuclear lineage …

In 1981 I established kingdom Chromista, distinguished from Plantae because of its more
complex chloroplast-associated membrane topology and rigid tubular multipartite ciliary …

Developing a detailed understanding of how all known forms of life are related to one
another in the tree of life has been a major preoccupation of biology since the idea of tree …
