Iron nutrient deficiency was investigated in leaves of hydroponically grown sugar beets (Beta vulgaris) to determine how ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) gene expression is affected when thylakoid components of photosynthesis are diminished. Rubisco polypeptide content was reduced by 60% in severely iron-stressed leaves, and the reduction was directly correlated to chlorophyll content. The concentration of Rubisco protein in iron-stressed leaves was found to be…

Responses of Arabidopsis thaliana to bicarbonate-induced iron deficiency

Morpho-physiological and biochemical responses of Arabidopsis thaliana to bicarbonate-induced iron deficiency were investigated and Root Fe(III)-chelate reductase and phosphoenolpyruvate carboxylase (PEPC) activities were significantly enhanced, but leaf ribulose 1.5-bisphosphateCarboxyl enzyme (Rubisco) activity was decreased.

Photosystem II efficiency in low chlorophyll, iron-deficient leaves

Iron-chlorotic leaves were protected not only by the decrease in leaf absorptance, but also by down-regulation mechanisms enhancing non-photochemical quenching and thermal dissipation of the light absorbed by PS II within the antenna pigment bed.

Modulation of macronutrient metabolism in barley leaves under iron-deficient condition

The adaptation of macronutrient metabolism to Fe deficiency in barley leaves is discussed and ribulose-1,5-bisphosphate carboxylase/oxygenase protein and nitrite reductase, sulfite reduct enzyme, and ferredoxin-dependent glutamate synthase mRNAs were reasonably decreased.


SUMMARY A comparative study of two lettuce varieties (Lactuca sativa: ‘Romaine’ and ‘Vista’) was conducted to understand the effect of iron deficiency on growth, biomass allocation, chlorophyll

Carbon monoxide improves adaptation of Arabidopsis to iron deficiency.

CO may play an important role in improving plant adaptation to iron deficiency or cross-talking with NO under the iron deficiency, as indicated by the observation that CO can regulate iron-homeostasis in iron-starved Arabidopsis.

Enhanced plant tolerance to iron starvation by functional substitution of chloroplast ferredoxin with a bacterial flavodoxin

The results indicate that Fld could compensate Fd decline during episodes of Fe deficiency by productively interacting with Fd-dependent pathways of the host, providing fresh genetic resources for the design of plants able to survive in Fe-poor lands.

Suppression of the soybean (Glycine max) Phytoglobin GmPgb1 improves tolerance to iron stress

Iron is an important microelement implicated in a variety of processes including chlorophyll synthesis and chloroplast development. Iron deprivation alters nitric oxide (NO) homeostasis, and

Fe deficiency induced changes in rice (Oryza sativa L.) thylakoids

It is demonstrated that photosystem I (PSI) is the primary target for iron deficiency, while the changes in photosystem II (PSII) are important for rebuilding a balance in disrupted energy utilization and dissipation caused by differential degradation of photosynthetic components.

Nitric Oxide Improves Internal Iron Availability in Plants1

A biological action of NO on the availability and/or delivery of metabolically active iron within the plant is supported and a role for endogenous NO in iron nutrition is supported.

Response of Arabidopsis to iron deficiency stress as revealed by microarray analysis.

It seemed likely that the energy demand in roots required for the Fe deficiency response exceeded the capacity of oxidative phosphorylation, and an increase in carbon import and anaerobic respiration were required to maintain metabolism.



Specific mRNA and rRNA Levels in Greening Pea Leaves during Recovery from Iron Stress.

Kinetic considerations suggest that the changes observed represent a coordinate series of events initiated by readdition of Fe and occurring in parallel, and that a rhythm in greening leaves was hard to detect and was prominent in the Fe-sufficient controls, persisting undamped through three full cycles for both mRNAs and hence is probably circadian.

Changes in Thylakoid Galactolipids and Proteins during Iron Nutrition-Mediated Chloroplast Development.

Iron deficiency caused an increase in the free chlorophyll band under the conditions of gel electrophoresis used, suggesting that proteins are inserted secondarily into the galactolipid matrix of the thylakoid membrane during development.

Influence of Iron Chlorosis on Pigment and Protein Metabolism in Leaves of Nicotiana tabacum L.

Experiments were conducted on Nicotiana tabacum, L. to study the relation in the grana among chlorophylls, carotenoids, and proteins. The effect of iron chlorosis on protein and pigment synthesis was

Limiting factors in photosynthesis.

The possibility of using Fe stress as an experimental tool in the study of limiting factors was explored and it is suggested that the effect of Fe stress may be sufficiently specific for it to be used for the control and study of photochemical capacity in vivo.

Light limitation of photosynthesis and activation of ribulose bisphosphate carboxylase in wheat seedlings.

Comparison of CO(2) exchange rate, RuP(1,5-bisphosphate) level, and activation of the carboxylase indicates that light limitation of photosynthesis can be due to two factors: the availability of RuP (2) in dark to dim light andactivation of the RuP.(2) carboxylyase inDim light and higher irradiances.

Limiting Factors in Photosynthesis: III. Effects of Iron Nutrition on the Activities of Three Regulatory Enzymes of Photosynthetic Carbon Metabolism.

When Fe was withheld from sugar beets, the activities of NADP-glyceraldehyde-3-phosphate dehydrogenase, fructose 1,6-bisphosphatase, and ribulose 5- phosphate kinase were not diminished, while chlorophyll per area was decreased, which support the view advanced earlier that the photosynthetic effects of Fe deprivation are mediated by changes in the lamellar components of chloroplasts.

Abscisic acid is involved in the iron‐induced synthesis of maize ferritin.

The general conclusion of this work is that the synthesis of the same protein in response to the same environmental signal can be controlled by separate and distinct mechanisms in plants and animals.

Iron induction of ferritin synthesis in soybean cell suspensions.

Results show that in soybean cell cultures, the mechanism of regulation of ferritin synthesis in response to iron does not result from recruitment of preexisting mRNA, and confirm that in plant systems, ferritIn synthesis results from increased transcription of the corresponding genes.

Photosynthesis and Activation of Ribulose Bisphosphate Carboxylase in Wheat Seedlings : Regulation by CO(2) and O(2).

The mechanism for changing activation of the RuBP carboxylase in the light involves not only Mg(2+) and pH changes in the chloroplast stroma, but also the effects of binding RuBP to the enzyme.
