Subsidiary cell formation in Poaceae stomatal complexes
Polarisation and asymmetrical division generating the Poaceous subsidiary cells constitutes a very attractive model for the study of local intercellular stimulation. Auxin operates as an inductive stimulus while PIN...

ARP2/3 complex links cell wall assembly and auxin distribution
The protein complex ARP2/3 is responsible for nucleating actin, and its loss results in multiple defects in young seedlings of Arabidopsis thaliana. Sahi et al. show that plants lacking the ARP2/3 complex have defects...
Two-stage patterning dynamics in conifer cotyledon morphogenesis
Conifers form a single whorl of multiple cotyledons (embryonic leaves), unlike monocots and dicots. Polar transport of the hormone auxin affects outgrowth of distinct cotyledons, but not the radial positioning of the...

Egg activation and actin-myosin dependent elongation of the Dictyota zygote
Male gametes need only 1 min to find the egg, fuse, induce homogenous cell wall secretion and start showing adhesive properties, underlying the role of the ECM as a fast sperm block in D. dichotoma.
Space matters in flower development
Flower meristems have the capacity to expand throughout their development, generating space for new structures. Claßen-Bockhoff and Meyer demonstrated this by the example of corona formation in passionflowers. The...
Shoot development in alfalfa plants competing for light
Developmental processes control plant and crop leaf area expansion in alfalfa and differ in their response to light competition intensity.

Turing’s centenial flowers
When flowers are mentioned in the context of Alan Turing (OBE, FRS, maths genius, tortured soul, ‘an enigma inside a colossus’, and one of the main members of the group of Bletchley Park code-breakers who were...
