“…Indeed, numerous recent studies indicate a co-operative effect between ABA and other phytohormones in various physiological events, and that these effects are dependent on the species, conditions, periods and sites in which the hormones function. Such examples include the effects of methyl jasmonate on plant transpiration (Lee et al 1996;Wang 1999) through the regulation of stomatal closure (Raghavendra & Reddy 1987) in co-operation with ABA and mediation by reactive oxygen species production (Suhita et al 2004), as well as its interaction with ethylene and ABA (Tanaka et al 2005).…”

The relationship between nitric oxide (NO) reduction and the inhibition of abscisic acid (ABA)-induced stomatal closure by ethylene was analysed. ABA treatment induced NO production and stomatal closure, but ethylene inhibited the effects of ABA on these two parameters. Like 2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (cPTIO), a specific scavenger of NO, haemoglobin (Hb), the potent scavenger of NO/carbon monoxide (CO) and N G -nitro-LArg-methyl ester (L-NAME), an inhibitor of animal nitric oxide synthases (NOS; EC 1.14.13.39), both the ethylene-releasing compound 2-chloroethylene phosphonic acid (ethephon, ETH) and 1-aminocyclopropane-1-carboxylic acid (ACC), the immediate precursor of ethylene, were found to inhibit stomatal closure by ABA and to reduce NO levels by ABA in guard cells, indicating that the ethylene-caused inhibition of ABA-induced stomatal closure involves a decrease in NO levels in guard cells. In addition, and similar to cPTIO and Hb, ACC/ETH suppressed sodium nitroprusside (SNP)-induced stomatal closure and NO levels in guard cells treated with SNP in the light. ACC/ETH also reopened stomata that had been closed by ABA and reduced NO levels that had been generated by ABA, showing that ethylene causes NO removal in guard cells. However, the above-mentioned effect of ACC/ETH was dissimilar to that of L-NAME, which was incapable of reducing NO levels by SNP or abolishing NO that had been generated by ABA. We suggest that ethylene probably induces NO removal, thereby reducing NO levels in Vicia faba guard cells, and finally inhibits stomatal closure induced by ABA. Furthermore, the pattern of NO reduction caused by ethylene is also discussed.

“…The strategy of exogenous application of various organic osmolytes, osmoprotectants, and growth regulators such as abscisic acid, benzyladenine (Pospíšilová and Baťková 2004), proline (Ali et al 2007), ascorbic acid (Dolatabadian et al 2009), chitosan (Yang et al 2009), glycinebetaine, salicylic acid, nitrous oxide, brassinosteroids (Farooq et al 2010), methyl jasmonate (Wang 1999) to plants was regarded vital technique to alleviate the deleterious effects of drought stress in plants. Out of the various stress ameliorating materials, glycinebetaine (GB) is considered an effective one.…”

Glycinebetaine acts as an osmoprotectant and is closely related with drought resistance. In the present study, glycinebetaine (GB) was exogenously-applied to two contrasting maize cultivars, Dongdan-60 and ND-95, to see whether GB improves drought resistance. Maize cultivars were grown with normal water supply till the heading stage and then exposed to two levels of soil moisture, well-watered control and drought-stressed, and then GB solution of 100 mmol was foliar applied five days after moisture treatments were imposed. The gas exchange and chlorophyll concentration were substantially declined in both maize cultivars under water stressed conditions. However, this reduction was less in Dongdan-60 than ND-95. Nonetheless, GB-treated plants considerably maintained higher gas exchange rate and chlorophyll concentration during drought stress than non-GB treated plants. The GB-induced improvement in gas exchange and chlorophyll synthesis under water stress ultimately resulted in improved growth and yield in both maize cultivars. Furthermore, the positive responses to exogenous GB application were more pronounced in Dongdan-60 as compared to ND-95 in all traits examined under water-deficit conditions. In conclusion, exogenously applied GB to maize crops could improve gas exchange, chlorophyll synthesis, growth and yield of maize.

(2011): Antioxidant capacity and antioxidants of strawberry, blackberry, and raspberry leaves. Czech J. Food Sci., 29: 181-189.The total phenolic content (Folin-Ciocalteu method), free radical scavenging ability expressed as DPPH value, ferric reducing antioxidant capacity (FRAP), and oxygen radical absorbance capacity (ORAC) were determined in water extracts of leaves from rosaceae family plants (Fragaria vesca L., rubus fructicosus L., and rubus idaeus L.). The antioxidant capacities of the extracts (in the order of the above mentioned methods) were 73.6-88.9%, 60.1-71.4%, 49.7-78.0% respectively, and 45.3-66.5% of that of green tea water extract. Further, the presence of 15 compounds (gallic acid, rutin, ellagic acid, caffeic acid, p-coumaric acid, quercetin, kaempferol, myricetin, quercetin-3-d-glucoside, ascorbic acid, (+)-catechin, (-)-epicatechin, epicatechingallate, epigallocatechin, procyanidin B1) was studied by HPLC-ECD and their antioxidant capacities were compared to the antioxidant capacity of the extracts. Out of the compounds studied, mostly (+)-catechin, ellagic acid, and (-)-epicatechin participated in the antioxidant capacities of the studied plant leaves water extracts. The antioxidant capacity of leaves infusions (determined by DPPH method) was lower than those of red wines and tea infusions, but comparable to the antioxidant capacities of white wines and fruit beverages. In the screening study comparing the antioxidant capacities (AC) (measured by DPPH method) of seventeen Czech medicinal plants, the leaves of strawberry (Fragaria vesca L.), blackberry (rubus fructicosus L.) and raspberry (rubus idaeus L.) belonged to the most efficient plants tested (Buři-čová & Réblová 2008). The AC of their extracts were comparable to and in some cases even higher than AC of the studied plants from the family Lamiaceae (oregano, sweet balm, thyme, dead-
