Tubulins’ Ensemble in Onion and Its Properties

Resumo

With an ensemble of tubulins in plants using gravitational mass spectroscopy (GMS), the dynamics of domains in the region of tubulin coil oscillations (43–60 kDa) in onion roots was searched. At the ends of roots, the signals from six tubulin oscillators with masses of 43.288, 46.231, 49.412, 52.698, 55.940, and 59.433 kDa were detected. They were then compared with those in the side part of the roots, both in the biomatrix (in vivo) and in the dehydrated root samples. These domains were found to be mostly in the expanded forms. The influence of external sound frequencies being identical with the oscillation frequencies of these domains (1337 ± 1 Hz) forced the domains to accept the collapsed conformations (after 15 min) and, thereby, stop the growth of the roots. A microtubule model based on six kinds of tubulins and water clusters and also a model for blocking the growth of the end with collapsed coils of proteins were given.
