Ectocarpus is a genus of filamentous, marine brown algae. Brown algae belong to the
stramenopiles, a large supergroup of organisms that are only distantly related to animals …

Background A common feature of most genetic sex-determination systems studied so far is
that sex is determined by nonrecombining genomic regions, which can be of various sizes …

In many eukaryotes, genetic sex determination is not governed by XX/XY or ZW/ZZ systems
but by a specialized region on the poorly studied U (female) or V (male) sex chromosomes …

Seaweed genetic engineering is a transgenic expression system with unique features
compared with those of heterotrophic prokaryotes and higher plants. This study discusses …

The brown algae are an interesting group of organisms from several points of view. They are
the dominant organisms in many coastal ecosystems, where they often form large …

This article describes the standard procedure for growing Ectocarpus in the laboratory. The
culture is started with partheno-sporophyte (or sporophyte) filaments because this is the …

Although evolutionary transitions from sexual to asexual reproduction are frequent in
eukaryotes, the genetic bases of these shifts remain largely elusive. Here, we used classic …

Brown algae are one of the most developmentally complex groups within the eukaryotes. As
in many land plants and animals, their main body axis is established early in development …

Three types of sex chromosome system exist in nature: diploid XY and ZW systems and
haploid UV systems. For many years, research has focused exclusively on XY and ZW …

The model brown alga Ectocarpus has a haploid‐diploid life cycle, involving alternation
between two independent multicellular generations, the gametophyte and the sporophyte …
