Differential Expression Of Soluble Pyrophosphatase Isoforms In Arabidopsis Upon External Stimuli, Zahi̇de Nesli̇han Öztürk, Steffen Greiner, Thomas Rausch
Differential Expression Of Soluble Pyrophosphatase Isoforms In Arabidopsis Upon External Stimuli, Zahi̇de Nesli̇han Öztürk, Steffen Greiner, Thomas Rausch
Turkish Journal of Botany
In plants, pyrophosphate (PPi), generated in a wide range of reversible anabolic reactions, is hydrolyzed by pyrophosphatases. The presence of tonoplast- and Golgi-integral H+-translocating pyrophosphatases in plants led to the conclusion that plant cytosol has no soluble pyrophosphatase activity. However, the Arabidopsis thaliana (L.) Heynh. Genome also encodes five soluble pyrophosphatase isoforms (Ppas). There are almost no data in the literature on their redundancy in plant metabolism; therefore, we performed expression analyses of A. Thaliana soluble pyrophosphatase isoforms in response to external stimuli including carbohydrate status, hormone action, and stress exposure. The results revealed pronounced specificity for each isoform. Interestingly, …
