“…Lipidic materials are required for adequate leaf growth and their synthesis may be affected by Fe deficiency. Indeed, it is plausible that Fe shortage affects cuticle formation via a limited production of lipidic material, as it was suggested to occur in pea and peach thylakoids (Abadía et al 1988;Abadía 1992;Monge et al 1993). …”

Leaf structural changes associated with iron deficiency chlorosis in field-grown pear and peach: physiological implications

Plants grown in calcareous, high pH soils develop Fe deficiency chlorosis. While the physiological parameters of Fe-deficient leaves have been often investigated, there is a lack of information regarding structural leaf changes associated with such abiotic stress. Iron-sufficient and Fe-deficient pear and peach leaves have been studied, and differences concerning leaf epidermal and internal structure were found. Iron deficiency caused differences in the aspect of the leaf surface, which appeared less smooth in Fe-deficient than in Fe-sufficient leaves. Iron deficiency reduced the amount of soluble cuticular lipids in peach leaves, whereas it reduced the weight of the abaxial cuticle in pear leaves. In both plant species, epidermal cells were enlarged as compared to healthy leaves, whereas the size of guard cells was reduced. In chlorotic leaves, bundle sheaths were enlarged and appeared disorganized, while the mesophyll was more compacted and less porous than in green leaves. In contrast to healthy leaves, chlorotic leaves of both species showed a significant transient opening of stomata after leaf abscission (Iwanoff effect), which can be ascribed to changes found in epidermal and guard cells. Results indicate that Fe-deficiency may alter the barrier properties of the leaf surface, which can significantly affect leaf water relations, solute permeability and pest and disease resistance.

“…Abadía et al (1988) found changes in the lipid composition of pea leaves as a response to iron deficiency. The ratio of mono-galactosyldiglycerol to di-galactosyldiglycerol in thylakoids decreased in Fe-deficient plants (Monge et al, 1993). As a result, the thylakoids were more rigid in chlorotic than in green plants (Abadía et al, 1989b;Abadía, 1992).…”

“…The nutritional relationships identified were the ratios P:Fe (Köseoglu, 1995a;Mengel et al, 1984;Wei et al, 1995), K:Ca (Abadía et al, 1989b;Abadía et al, 1985;Garcia et al, 1999;Mengel et al, 1984;Montañés et al, 1990a), Fe:Mn (Lucena et al, 1990;Monge et al, 1993) and Zn:Fe (Nenova and Stoyanov, 1999). These ratios express nutritional imbalances that appear when iron immobilization in the plant takes place.…”

“…NO increases chlorophyll synthesis in high Zn plants either by directly increasing Fe uptake, directly increasing Fe translocation from roots to shoots, or lowering the uptake and accumulation of Zn so that there is an indirect effect on Fe concentration in the leaves. Some reports indicate a linear relationship between chlorophyll content and leaf Fe, for example, in tomato (Szlek et al, 1990), in pepper , in peach (Mengel et al, 1993), and in tobacco (Miller et al, 1995).…”

A short term experiment was carried out to study the effects of exogenous nitric oxide (NO) on some growth parameters and mineral nutrients of maize grown at high zinc (Zn). Maize seedlings were planted in pots containing perlite and subjected to 0.05 or 0.5 mM Zn in nutrient solution. Nitric oxide (0.1 mM) was sprayed to the leaves of maize seedlings. High Zn reduced total dry matter, chlorophyll (Chl.) content and leaf relative water content (RWC), but increased proline content and membrane permeability. Foliar application of NO significantly increased chlorophyll content, RWC and growth of plants treated with high Zn, and significantly reduced their membrane permeability and proline contents. High Zn resulted in increased leaf and root Zn, but lower concentrations of leaf phosphorus (P), and iron (Fe). Foliar application of NO lowered leaf and root Zn and increased leaf and root nitrogen (N) and leaf Fe in the high Zn Downloaded by [University of California, San Diego] at 02:50 21 June 2016 ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 2 plants. These results clearly demonstrated that externally-applied NO induced growth improvement in maize plants was found to be associated with reduced membrane permeability under high zinc. Results can be concluded that NO may be involved in nutritional and physiological changes in plants subjected to high Zn.
