“…13) To prevent this phenomenon, rice plants were treated with ALA in the light in the present study. The results from rice corresponded with previous reports showing an ameliorative effect of ALA on the growth of cotton 16) and potato (Solanum tuberosum L.) 35) under salt stress conditions. …”

“…Moreover, several studies showed that ALA had the potential to restore plant growth levels under salt stress conditions when it was applied at low concentrations. 16,17,35) The herbicidal action of ALA at high concentrations was reported to be due to the abnormal accumulation of chlorophyll intermediates in the dark. 11,12) These accumulated intermediates led to the formation of highly reactive singlet oxygen ( 1 O 2 ) when plants were transferred to the light and caused the death of plant cells by peroxidation of membrane lipids.…”

Mechanism of growth amelioration of NaCl-stressed rice (Oryza sativa L.) by .DELTA.-aminolevulinic acid

The mechanism of growth amelioration of NaCl-stressed rice (Oryza sativa L. cv. Nipponbare) by d-aminolevulinic acid (ALA) was investigated. Rice growth recovered when plants were pretreated with 0.1 or 1 mM ALA before treatment with 50 mM NaCl. There was no increase in chlorophyll content by ALA treatment, indicating that the growth recovery was not due to increased chlorophyll content although ALA is a precursor of chlorophyll biosynthesis. The activities of antioxidative enzymes, including catalase (CAT), glutathione reductase (GR), ascorbate peroxidase (APx), and superoxide dismutase (SOD), increased with ALA treatment. In particular, stimulation of CAT, GR, and APx activities by ALA was significant. The hydrogen peroxide (H 2 O 2 ) content decreased after ALA treatment under NaCl-stress conditions. Peroxidation of membrane lipids, as measured by ethane evolution, also decreased after ALA treatment. These results suggest that ALA induces growth amelioration in NaCl-stressed rice by stimulating antioxidative enzyme activity, which resulted in decreased reactive oxygen generation and lipid peroxidation.

“…However, ALA application improved the contents of Cu and Zn in the roots of drought-stressed plants, but had no effects on the contents of other elements (Table 7). In agreement with our results, Watanabe et al (2000) reported that ALA does not affect the uptake of K, Mg, and Ca by cotton (Gossypium L.) roots under 1.5% salt (NaCl) stress. On the contrary, Naeem et al (2010) found that ALA application enhanced the uptake of macro-and micronutrients, except for sulfur (S), Cu and Mn, in the roots of B. napus under salinity stress.…”

In the present study, the roles of foliarly applied 5-aminolevulinic acid (ALA) in photosynthetic parameters, ion contents and expression of several photosynthetic genes were investigated in rapeseed (Brassica napus L.) under well watered and drought conditions. Drought stress reduced relative plant growth rate and leaf water content (RWC), and contents of photosynthetic pigments, starch, soluble proteins and ions in roots. This type of stress, however, stimulated the accumulation of soluble sugars and free amino acids, as well as leaf proline contents. The transcript levels of photosynthetic genes were also down-regulated under drought stress. Exogenously applied ALA partially reduced growth inhibition and increased RWC and chlorophyll contents under drought conditions. The expression of photosynthetic genes was induced by ALA under both normal and drought conditions, which may contribute to an increased photosynthetic capacity. The ALA application further improved the accumulation of hexose and sucrose, accompanied by the maintenance of starch contents in the leaves and possibly relatively higher RWC under drought stress. Based on these results, we suggest that ALA promotes plant growth under drought stress via improving photosynthetic assimilation, increasing chlorophyll content and inducing the expression of several photosynthetic genes.

“…In addition to these physiological actions, PGRs are known to mitigate certain growth stresses of plants; e.g., crop injuries caused by herbicides and salinity were mitigated by hymexazole (3-hydroxy-5-methylisoxazole) and aminolevulinic acid. [12][13][14] In bioassays utilizing soil culture with nutrient supplements, the effects of PGRs on the Cd stress of plants may be difficult to measure with precision because of the soil adsorption of PGRs and also the effects of plant nutrients on growth. Therefore, water culture, in which plants can be cultured without soils and nutrients, and Japanese millet (Echinochloa frumentacea Link), belonging to the same family as barnyardgrass (Echinochloa crusgalli (L.) Beauv.…”

Effect of hymexazole (3-hydroxy-5-methylisoxazole) on cadmium stress and accumulation in Japanese millet (Echinochloa frumentacea Link)

The mitigating effects of hymexazole (HMI), choline chloride, indolebutyric acid, ethephon and isoprothiolane on cadmium (Cd) stress and accumulation in Japanese millet were evaluated under aquatic conditions. Among five PGRs, HMI showed the highest mitigating effect; however, in this experiment, almost no effect of calcium (Ca), which has been demonstrated to be a Cd mitigator, on Cd accumulation was observed and the mitigating effect of Ca on Cd stress was less than that of HMI.
