Rhythmical changes of a level nitric oxide (NO) in roots etiolated seedlings of pea (Pisum sativum L.) and influence of exogenous calcium
Journal Title: Журнал ÑтреÑÑ-физиологии и биохимии - Year 2014, Vol 10, Issue 4
Abstract
Studied time dynamics (during 60 mines) a level oxide nitric (NO) in cross cuts of roots 2 – day etiolated seedlings of pea sowing ([i]Pisum sativum[/i] L.) by use of fluorescent probe DAF-2DA and a fluorescent microscope depending on action exogenous calcium (Ca[sup]2+[/sup]). During an exposition of seedlings on water, solution CaCl[sub]2[/sub] are shown fluctuation in level NO in roots – his increase and decrease that testifies to the certain rhythm in generation NO. Exogenous factors (Ca[sup]2+[/sup]) change time dynamics of level NO in comparison with variant “water”. Ca[sup]2+[/sup]chelate EGTA removes action exogenous calcium on rhythmical change of a level NO in roots. Results are discussed in aspect of close interference of signaling systems and molecules (Ca[sup]2+[/sup], NO, Н[sub]2[/sub]О[sub]2[/sub]).
