The brown alga Ectocarpus exhibits a haploid-diploid life cycle with an alternation between two multicellular generations : a haploid gametophyte and a diploid sporophyte. Two mutants exhibit homeotic switching between the sporophyte and gametophyte programs, reiterating the gametophyte program instead of switching to the sporophyte. These mutants, called ouroboros (oro) et samsara (sam), carry mutations into two different genes that code for TALE homeodomain transcription factors. This thesis aimed to characterize these two transcription factors and the chromatin dynamics associated with the alternation of generation in Ectocarpus. This thesis presents the characterisation of the oro and sam mutants and a transcriptomic comparison of the m...
