Variable petal number in Cardamine hirsuta is explained by regulatory changes in the MADS-box gene APETALA1 that relaxed its epistasis over mapped QTL in the C. hirsuta genome.
Transgenic analysis reveals a role for LEAFY in ferns that supports a trajectory from general to floral meristem-specific function as land plants evolved.
Arbuscular mycorrhizal fungi-induced hydroxy- and carboxyblumenol C glycosides accumulate in plant shoots and allow for facile high-throughput screening for functional plant-AMF associations.
Growing upwards in the young seedling is controlled by two cooperative mechanical mechanisms: cellulose orientation in inner tissues and differential elasticity in epidermal cells.
Arabidopsis RNA processing factor SERRATE associates with the chromatin of intronless genes, which are usually expressed at low levels, to enhance polymerase II association.
Light signaling components interact with a histone H2B deubiquitination module, adjusting chromatin states at global level during Arabidopsis seedling development.
Cytological and biochemical analyses reveal Arabidopsis formin 2 is involved in regulating PD permeability by anchoring actin filaments to PD and stabilizing them through actin filament barbed end capping activity.
