A stochastic model of phyllotaxis can explain the striking irregularities observed in the spiral patterns of plants and predicts that perturbation patterns provide key information about the underlying biochemical mechanisms.

The hormonal circuitry controlling development in plants can be studied and re-programmed with hormone activated Cas9-based repressors.

Rhythmic centrifugal waves of auxin traveling through the tissue provides high definition positional information to cells that is not only spatial but also temporal.

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.

SWI/SNF chromatin remodeling complexes act as ‘gatekeepers’ for auxin responses and directly interact with the auxin response factor MONOPTEROS.

Flowers did bloom in the Early Jurassic.

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.

Leaf position, shape and orientation are pre-patterned by cell type boundaries in the shoot meristem.

Combining high-resolution imaging with automated image segmentation and supervised machine learning achieves accurate cellular feature extraction and automated cell type recognition in a large-scale developmental process.

Comparative genetics between distant plant species shows that for the PIN auxin transport proteins differential membrane and tissue-level accumulation, transport activity, and interaction result in different functional properties in the shoot post transcription.
