Dehydrin Association with Supercomplexes of Pea Seedlings Mitochondria Under Hypothermia

The reaction of plant cell on many stressful conditions is accompanied by accumulation of protective proteins. Dehydrins are widespread in a plant kingdom and accumulated in reply to a drought, freezing, salt stress, and also high temperature. Earlier we found the accumulation of dehydrins in mitochondria of some plants under various stresses. This work aims to study the quantitative changes and localization of dehydrins in the mitochondria of pea seedlings under low temperature impact of varying intensity and duration. It has been found that the dehydrins content in mitochondria of pea seedlings subjected to the action of low temperatures increases. The maximum dehydrins content was founds after cold hardening which is accompanied by cryotolerance increasing. For the first time it was established that the part of dehydrins of plant mitochondria is localized in the several organellar supercomplexes

First experimental results obtained using the highpower free electron laser at the siberian center for photochemical research

The first lasing near the wavelength of 140 µm was achieved in April 2003 using a high-power free electron laser (FEL) constructed at the Siberian Center for Photochemical Research. In this paper we briefly describe the design of the FEL driven by an accelerator–recuperator. Characteristics of the electron beam and terahertz laser radiation, obtained in the first experiments, are also presented in the paper.У Сибірському центрі фотохімічних досліджень навесні 2003 року отримана генерація випромінювання з довжиною хвилі 140 мкм на потужному лазері на вільних електронах (ЛВЕ). У роботі коротко описана конструкція ЛВЕ на базі прискорювача рекуператора і представлені результати вимірювання деяких параметрів електронного пучка і терагерцового випромінювання.В Сибирском центре фотохимических исследований весной 2003 года получена генерация излучения с длиной волны 140 мкм на мощном лазере на свободных электронах (ЛСЭ). В работе кратко описана конструкция ЛСЭ на базе ускорителя рекуператора и представлены результаты измерения некоторых параметров электронного пучка и терагерцового излучения
