Alternative oxidase: a defence against metabolic fluctuations?

摘要: An increasing number of oscillating or fluctuating cellular systems have been recently described following the adaptation fluorescent technology. In diverse organisms, these variously involve signalling factors, heat production, central metabolism and reactive oxygen species (ROS). response to many plant stresses primarily via influence ROS, changes in mRNA protein levels vivo activity alternative oxidase are often observed. However, several investigations, a lack correlation between mRNA, has evident. This discrepancy made it questionable whether induction importance regulating pathway vivo, being diagnostic for role stress tolerance ROS avoidance. Here, we suggest counteracting deleterious short-term metabolic fluctuations, especially under conditions. model emphasizes peak establishing allows an amalgamation present status physiological, molecular knowledge.
