Lessons from 138 bryophyte genomes
Plant Science Research WeeklyPangenomes are amazing resources that provide glimpses into evolution that no single genome can capture. This new article by Dong et al. is a treat, as it describes the findings from a compilation of 138 bryophyte genomes, of which 123 are newly sequenced. Bryophytes are non-vascular plants (mosses,…
Review: Genome evolution in plants and the origins of innovation
Plant Science Research WeeklyLand plants have enormous diversity; however we do not fully understand how this has arisen. In this review article James Clark discusses how genome dynamics and gene loss contribute to genome evolution and the generation of diversity and complexity. He explains how genome evolution is non-homogenous…
No auxin signaling, no organogenesis
The Plant Cell: In a NutshellSuzuki et al. examine the effects of auxin signaling on development of the liverwort Marchantia polymorpha.
Hidemasa Suzuki, Hirotaka Kato, Megumi Iwano, Ryuichi Nishihama, Takayuki Kohchi
Background: Land plants alternate diploid (2n) and haploid (n) generations. The plant hormone auxin regulates…
Review: Bryophytes as model systems for studying evolutionary cell and developmental biology (Plant Cell)
Plant Science Research WeeklyThe development of Arabidopsis as a model system greatly advanced the field of plant cell biology by bringing in molecular approaches, so much of our conceptual foundation rests on studies from angiosperms. More recently, model bryophytes, particularly Marchantia polymorpha (liverworts) and Physcomitrium…
KARRIKIN INSENSITIVE2-dependent signaling in the liverwort Marchantia polymorpha
The Plant Cell: In a NutshellMizuno et al. show that genes in the KARRIKIN INSENSITIVE2-dependent signaling pathway are conserved in the liverwort Marchantia polymorpha and control early development of the thallus.
Yohei Mizuno and Junko Kyozuka
Background: Plants hormones play crucial roles in growth and development. Karrikins…
