"NUMEROUS BIOTIC SIGNALS are sensed and modify the phenotype. These include the presence, absence and identity of neighbours, cooperation, mutualism, disturbance, trampling, herbivory, parasitism and space." http://link.springer.com/article/10.1007/s00114-005-0014-9 View in LinkedIn
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
DEEP COORDINATION. "Higher plants integrate the signaling complex; they process the information and construct a composite response specific to the range and balance of perceived signals." http://link.springer.com/article/10.1007/s00114-005-0014-9 View in LinkedIn
NEIGHBOURS. "Even after moved to different soils, plants retain the memory of their original neighbours for several months up to a year." http://link.springer.com/article/10.1007/s00114-005-0014-9 View in LinkedIn
PLASTIC PHENOTYPES. "Since the phenotype differs with each new neighbour, the ecological niche is not a fixed quantity but like the phenotype itself, is plastic in character and changes as growth continues." http://link.springer.com/article/10.1007/s00114-005-0014-9 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
