(n.) The order or arrangement of leaves on the stem; the science of the relative position of leaves.
Example Sentences:
(1) The symmetrical arrangements of monomers into such cylindrical structures as microfilaments of actin, flagella of bacteria, microtubules of many organisms, and the protein coats of viruses can be specified by citing the index numbers of two or three sets of contact parastichies, or helical ranks of monomers, as has been done in classical studies of phyllotaxis.
(2) In spiral phyllotaxis (3:2) a single angular discontinuity appears to be involved initially; the pertinent older leaves are three and five plastochrons older than the leaf being formed.
(3) This latter type of approach is put forward as being able to give a general framework in which to organize the concepts, results, and models in phyllotaxis in a way that produces a synergy of efforts.
(4) An algorithm, called the phi-model, based on the observation of the meaningful and symmetry-generating presence of the golden ratio phi in all types of spiral patterns, and consequently in all types of regular patterns in phyllotaxis, is proposed.
(5) The paper shows convergences between the results found in various models of phyllotaxis.
(6) The model is suggested by a property of the allometry-type model for pattern recognition in phyllotaxis.
(7) This pattern of expression has implications for how flo affects phyllotaxis, organ identity, and determinacy.
(8) The necessity of doing so is seen clearly when one considers that phyllotaxis-like patterns are encountered in other fields of research, so that the problem appears to transcend the strict botanical substratum.
(9) In whorled phyllotaxis two angular discontinuities appear to be involved with each new leaf; the pertinent older leaves are just one plastochron older than the leaf being initiated.
(10) It produces biophysically plausible schemes for the progressive development of various leaf structures and for the cyclical revision of apical structure seen in various types of phyllotaxis.
(11) The symmetry of alpha-helix subunit arrangement in the virion is related to the symmetry of leaf arrangement in plants (phyllotaxis) and is conserved in a molecular rearrangement model of the telescope.
(12) The phi-model is a link between the two entropy models in phyllotaxis and offers a nice correspondence with the minimal entropy model generated by a systemic and holistic approach.
(13) There are two major differences from previous theories of phyllotaxis.
(14) It shows that a synergic approach is needed to deal with the problems of phyllotaxis.
(15) However, in the literature it has not yet been honored as the basis for constructing the phyllotaxis in centric, planar models.
(16) Theory for leaf patterning, phyllotaxis, is usually expressed in terms of interactions in the surface of the apical dome of the shoot.
