Succinate dehydrogenase (SDH) and fumarase enzyme activity and expression of genes encoding the SDH subunits A (Sdh1-2), B (Sdh2-3), C (Sdh3), D (Sdh4) and the mitochondrial (Fum1) and cytosolic (Fum2) isoforms of fumarase were quantified in maize (Zea mays L.) seedlings exposed to atmospheres of
Fumarase (EC 4.2.1.2) catalyzes reversible interconversion of malate and fumarate. It is usually associated with the tricarboxylic acid cycle in mitochondria, although the cytosolic form has also been detected. We investigated the expression of two fumarase genes and activities of the mitochondrial
Blue light inhibits succinate dehydrogenase and fumarase enzyme activity and gene expression in green leaves of maize (Zea mays L.). Irradiation of maize plants by blue light resulted in the transient decrease of transcripts of genes Sdh1-2 and Sdh2-3 encoding correspondingly the flavoprotein and
A specific high temperature-induced deficiency of chloroplast ribosome formation, as indicated by the absence of chloroplast rRNA, has been observed in the leaves of light- or dark-grown seedlings of Avena sativa L., Hordeum vulgare L., and Triticum aestivum L. at certain temperatures between 28 and
