The presented work examines the mechanism and conditions of.self.motion in bodies as systems of.interacting elements. It is shown how the oscillation parameters of.these elements determine the mode of.motion of.the system (body). In this case, the motion is considered as a consequence of.symmetry breaking of.f.rces in the systems themselves, and not as a reaction of.individual elements to external inf.uences. It is shown that such a violation takes place both in the gravitational f.eld and when the system moves by inertia. Examples of.the inf.uence of.changes in phase (φ) and f.equency (f. parameters of.the system elements on the velocity mode of.its motion in space are considered. The identity of.the causes of.self.motion is revealed both in the case of.gravitation and inertial motion.

The presence of.a single Otoceras species ( O. boreale ), morphologically very variable, at the base of.the Nekuchan f.rmation in Verkhoyansk, we believe, is to be obvious. Some morphological evidence leaves no doubt that two described morphs of. O. boreale are a strictly corresponding sexual dimorphic pair. It is very likely that Kummel's idea that Canadian O. concavum Tozer is an invalid species is truthf.l, considering the range of.variability seen in larger Siberian and Himalayan Otoceras f.una. Just above the upper Tatarian Imtachan f.rmation, the six stages of.ammonoid succession can be recognized within the lower part of.the Nekuchan f.rmation in the Setorym River Section: (a) Otoceras boreale ; (b) Otoceras boreale-Tompophiceras pascoei ; (c) Otoceras boreale-Tompophiceras pascoei- Aldanoceras ; (d) Tompophiceras pascoei-Otoceras boreale-Aldanoceras ; (e) Tompophiceras morpheous-T. pascoei-Aldanoceras ; (f. Tompophiceras morpheous-T. pascoei-Wordieoceras domokhotovi-Ophiceras transitorium; (g) Tompophiceras morpheous-T. pascoei, corresponding to the Otoceras boreale and Tompophiceras morpheous zones. In spite of.the domination of.Otocerataceae or Xenodiscaceae in both of.these zones and the presence of.some Permian type conodonts in the lower part of.the Otoceras boreale Zone, they seem to be early Induan in age on the basis of.the f.llowing arguments: (1) in contrast to the underlying regressive type sediments of.the Upper Tatarian Imtachan f.rmation, both the Otoceras boreale and the Tompophiceras morpheous zones of.the lowermost part of.the Nekuchan f.rmation correspond to the single transgressive cycle; (2) typical early Induan ammonoids ( Ophiceras and Wordieoceras ) have been recognized in the Tompophiceras morpheous zone; (3) all described ammonoid succession stages (a-g) are characterized by very gradual changes and theref.re correspond to the dif.erent parts of.the single zone

The participation of.O-methyltransf.rase (COMT) in phenylpropanoid-mediated capsaicinoid biosynthesis has long been proposed. f.rulic acid, a phenylpropanoid intermediate, is a precursor of.capsaicinoid biosynthesis and is produced f.om caf.eic acid by the action of.COMT. As previously reported that silencing Comt expression caused a drastic decrease in capsaicinoid accumulation, it was presumed that a Comt loss-of.f.nction mutation would cause loss of.pungency in Capsicum. This hypothesis was tested by cloning Comt1 and Comt2 f.om the placenta tissue of.the pungent cultivar Habanero. The phylogenetic analysis and comparison of.critical amino-acid residues f.r enzyme f.nction showed that the two COMTs had high similarity with the COMTs of.other plant species. Moreover, as the two Comts were both expressed in placenta tissue and expressed prior to the accumulation of.capsaicinoids, the two genes could be candidates f.r capsaicinoid biosynthesis. Second, Comt1 loss-of.f.nction mutants were screened f.om the germplasm. A truncated Comt1 transcript was expressed in non-pungent pepper No.3341 caused by deletion of.the genomic region. The predicted No.3341 COMT1 lacked His-265, which was absolutely necessary f.r enzymatic activity. Contrary to our expectations, the Comt1 mutation was not related to non-pungency of.No.3341, as the deletion of.Comt1 did not co-segregate with non-pungency in the f. population obtained f.om crossing No.3341 with Habanero. This result was conf.rmed by screening several pungent accessions harboring the same Comt1 deletion mutation. Although the participation of.COMT in phenylpropanoid-mediated capsaicinoid biosynthesis has long been proposed, our present study shows that Comt1 can not be a target f.r controlling f.uit pungency.
