It is possible that the decrease in DHAP content influences changes in the contents of pentose phosphate pathway metabolites such as S7P and
ribulose 5-phosphate (Ru5P).
crispata collected from five geographically separated sites along its distribution, using polymerase chain reaction (PCR) generated nucleic acid sequences from the large subunit of the chloroplast-encoded gene
ribulose bisphosphate/carboxylase (rbcL).
Transgenically produced glycinebetaine protects
ribulose 1,5-bisphosphate carboxylase/oxygenase from inactivation in Synechococcus sp.
The reduction of P uptake by the plant may lead to decreases in the consumption and production of ATP and NADPH, lower carboxylation/regeneration of
Ribulose 1,5 bisphosphate carboxylase oxygenase, decrease in the expression of genes related to photosynthesis (Machado et al.
On the contrary,
ribulose 1,5-bisphosphate carboxylase/oxygenase large subunit was up-regulated.
Discoveries in RuBisCO (
Ribulose 1,5-bisphosphate carboxylase/oxygenase): a historical perspective.
Furthermore, these fungal toxins might alter source-sink balance of onion plant by disrupting functioning of rubisco (
ribulose 1, 5-bisphosphate carboxylase) (Petit et al., 2006).
It is happened because methanol got oxidation in increasing the photosynthesis rate of potato and suppressed the photorespiration due to an increased C[O.sub.2], leaves intern, which enable
ribulose diphosphate-carboxylase compared with
ribulose diphosphate-oxidase [17,18,].
Their low net photosynthesis could be the result of a decreased electron transport rate in chloroplasts and a lower content of soluble protein (mainly
Ribulose 1,5 biphosphate, Kung & Marsho, 1976) per unit leaf area, which are documented from growth under low light intensities (Boardman, 1977).
Phosphogluconate dehydrogenase (Pgd) is an enzyme that converts 6-phosphogluconate to
ribulose 5phosphate in the oxidative branch of the pentose phosphate pathway, which produces NADPH as well as purine nucleotides [28].
Nonidentical subunits of
ribulose diphosphate carboxylase.
Sulfite affects the carbon fixation,
ribulose biphosphate carboxylase, glycolate oxidase activity, and photophosphorylation [25].
