The possibility of using Fe stress as an experimental tool in the study of limiting factors was explored. Results show that Fe stress decreased the chlorophyll (Chl) a, Chl b, carotene, and xanthophyll content of leaves of sugar beets (Beta vulgaris L.) and that the maximum rate of photosynthetic CO(2) uptake (P(max)) per unit area was linearly related to Chl (a + b) per unit area. Measurements of noncyclic ATP formation by isolated chloroplasts at light saturation indicate that photosynthetic… 

Liniiting Factors in Photosynthesis II . IRON STRESS DIMINISHES PHOTOCHEMICAL CAPACITY BY REDUCING THE NUMBER OF PHOTOSYNTHETIC UNITS 1 2

It has been proposed that Fe stress may be used in the study of limiting factors in photosynthesis as an expermental means of varying photochemical capacity in vivo (Plant Physiol 1980 65: 114-120).

Limiting Factors in Photosynthesis: VI. Regeneration of Ribulose 1,5-Bisphosphate Limits Photosynthesis at Low Photochemical Capacity.

Earlier work (SE Taylor, N Terry [1984] Plant Physiol 75: 82-86) has shown that the rate of photosynthesis may be colimited by photosynthetic electron transport capacity, even at low intercellular

Variation in photosynthetic electron transport capacity in vivo and its effects on the light modulation of ribulose bisphosphate carboxylase

The data suggest that the activation of RuBPCase could not solely account for the increases in the photosynthetic rate at high irradiances; RuB PCase reached maximal activation at irradiances well below light saturation for net photosynthesis.

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.

Limiting Factors in Photosynthesis: V. Photochemical Energy Supply Colimits Photosynthesis at Low Values of Intercellular CO(2) Concentration.

The results suggest that colimitation by photochemical energy supply at low C(i) may be mediated via effects on RuBPCase activation, and the effect of irradiance on ribulose bisphosphate carboxylase (RuB PCase) activation is investigated.

Iron nutrition-mediated chloroplast development.

The iron nutrition-mediated chloroplast development system provides a useful experimental approach for studying biomembrane synthesis and structural-functional relations of the photosynthetic apparatus.

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.

Early Iron Deficiency Stress Response in Leaves of Sugar Beet

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

Alterations in thylakoid membrane composition induced by iron starvation in sunflower plants

The HPLC analysis of the pigments associated with the green bands separated by Deriphat PAGE showed that the xanthophylls associated with both photosystems shifted toward the de‐epoxidated form following iron starvation, indicating the onset of a protective mechanism against photoinhibition at the levels of both photoystems.
