Abstract:
... 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 r ...

We conducted a study to evaluate the effects of leaf cutting on bulb weight and pungency of short-day onions after plant lifting in ‘TG 1015Y’, ‘Legend’, and ‘Texas Early White’ cultivars. When about 50% of the leaf had ...
