Seed dormancy and the control of germination.
TLDR
It is argued that adaptation has taken place on a theme rather than via fundamentally different paths and similarities underlying the extensive diversity in the dormancy response to the environment that controls germination are identified. Expand
Plant hormone interactions during seed dormancy release and germination
This review focuses mainly on eudicot seeds, and on the interactions between abscisic acid (ABA), gibberellins (GA), ethylene, brassinosteroids (BR), auxin and cytokinins in regulating theExpand
First off the mark: early seed germination.
TLDR
An integrated view on the early phase of seed germination is provided and it is shown that it is characterized by dynamic biomechanical changes together with very early alterations in transcript, protein, and hormone levels that set the stage for the later events. Expand
Endosperm-limited Brassicaceae seed germination: abscisic acid inhibits embryo-induced endosperm weakening of Lepidium sativum (cress) and endosperm rupture of cress and Arabidopsis thaliana.
TLDR
It is proposed that Lepidium is an emerging Brassicaceae model system for endosperm weakening and that the complementary advantages of Lepidium and Arabidopsis can be used in parallel experiments to investigate the molecular mechanisms of endos sperm weakening. Expand
Molecular mechanisms of seed dormancy.
TLDR
This review gives an overview of the present understanding of the mechanisms that control seed dormancy at the molecular level, with an emphasis on new insights. Expand
Transcriptional Dynamics of Two Seed Compartments with Opposing Roles in Arabidopsis Seed Germination1[W][OPEN]
TLDR
Gene expression profiling in two seed compartments uncovers two transcriptional phases during seed germination that are separated by testa rupture, and indicates a role for mechano-induced signaling at this stage and highlights the fates of the endosperm and radicle: senescence and growth, respectively. Expand
In Vivo Cell Wall Loosening by Hydroxyl Radicals during Cress Seed Germination and Elongation Growth1[W][OA]
TLDR
It is concluded that plant cell wall loosening by ·OH is a controlled action of this type of reactive oxygen species. Expand
Ethylene Interacts with Abscisic Acid to Regulate Endosperm Rupture during Germination: A Comparative Approach Using Lepidium sativum and Arabidopsis thaliana[W][OA]
TLDR
It is reported on a comparative seed biology study with the close Brassicaceae relatives Lepidium sativum and Arabidopsis thaliana showing that ethylene biosynthesis and signaling regulate seed germination by a mechanism that requires the coordinated action of the radicle and the endosperm cap. Expand
The NADPH-oxidase AtrbohB plays a role in Arabidopsis seed after-ripening.
TLDR
Reactive oxygen species produced by AtrbohB during after-ripening could act via abscisic acid (ABA) signalling or post-translational protein modifications as well as altered processing of stored pre-mRNAs seeds could react quickly to environmental changes. Expand
Members of the gibberellin receptor gene family GID1 (GIBBERELLIN INSENSITIVE DWARF1) play distinct roles during Lepidium sativum and Arabidopsis thaliana seed germination
TLDR
The gid1 mutant and whole-seed transcript analyses in Arabidopsis were combined with seed-tissue-specific analyses of its close relative Lepidium sativum, for which three GID1 orthologues were cloned. Expand
