NUANCED DISCRIMINATION. "Many signals modify the plant phenotype. Many abiotic signals are sensed by plants. For example, humidity, light, minerals, gravity, wind, snow melt, soil structure and composition, etc., and totaling about 20 in number, initiate phenotypic changes. Furthermore these signals are sensed and the intensity, the direction and the length of exposure are finely discriminated." http://link.springer.com/article/10.1007/s00114-005-0014-9 View in LinkedIn

SYMMETRICAL EXPRESSION. "An increasing number of studies from across angiosperms indicate that morphological shifts between radial symmetry and bilateral symmetry are correlated with independent transitions in asymmetric expression of members of the ECE clade of TCP TFs, of which CYCLOIDEA (CYC) was the first characterized member." ( TFs = transcription factors). http://onlinelibrary.wiley.com/doi/10.1111/nph.13198/full View in LinkedIn

SO ENDS this first of two weekends on the theme of floral symmetry. Symmetry is a pervasive theme in nature, from the quantum to the biological. It is still not clear why symmetry is such a powerful force, so seemingly keenly essential. In the case of flowers, the pollinators could as easily, it seems, have been conditioned on asymmetric flowers. But as we see, plants go to complicated generic solutions to maintain precise symmetric control. View in LinkedIn
