The circadian clock acts with light response pathways to tightly synchronize daily rhythms in maturation of hundreds of florets in sunflower, promoting timely visits by pollinators and creating ring-like patterns on developing heads.

The circadian clock may help to control the development patterns which allow the florets on a sunflower head to go through their final stages of maturation at precisely the right time.

Inbreeding compromises floral traits and reduces pollinator visitation rates disproportionally in female relative to male individuals in a dioecious plant and may thus interfere with the equilibrium of a complex co-evolutionary plant-insect relationship.

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.

Computational analyses, for the first time in plants, reveal how male-biased genes evolve faster than female-biased and unbiased genes.

MicroRNA-mediated repression of a DNA methyltransferase prevents the ectopic methylation of thousands of genes based on distinct chromatin features during embryogenesis, which can reduce expression and persist for weeks afterwards.

Light sheet microscopy was used to establish a method for live imaging of cellular events within Arabidopsis flower and for constructing a 3D model of flower at subcellular resolution.

Fluorescent sensors can track the movement and distribution of the plant hormone abscisic acid in roots and leaves in Arabidopsis.

Variation in autumnal expression from starting expression levels and initial cold-down-regulation, rather than epigenetic silencing, is the major field variable conferred by worldwide haplotypes of the floral repressor gene, FLC.

Step-wise processing of plant peptide hormone precursors by subtilisin-like proteinases in consecutive compartments of the secretory pathway is required for formation and secretion of the bioactive peptides.
