“…Our results hereby show that the positive influences of exogenous GB was via osmotic regulation rather than supplying nitrogen nutrition during DS, and was variable among different cultivars (Agboma et al 1997;Tables 3, 4, 5, 6). Externally-applied GB can rapidly penetrate through leaves and be transported to other organs, where it can contribute to improved stress tolerance by enhancing the ability to osmotically adjust of plant cell, maintaining stabilization and integrity of cell membrane (Mäkeläa et al 1996;Buchanan et al 2000;Sakamoto and Murata 2000;Taiz and Zeiger 2002;Zhang and Li 2004;Tables 3, 4, 5, 6) and enhancing ATPase activity in plant cell, which is beneficial to active absorption of inorganic ions such as K ? (Shibaha 1999;Zhang and Li 2004).…”

“…It has an important function as a non-osmotic regulator which can maintain cell membrane integrity (Sakamoto and Murata 2000). Hence, application of exogenous GB to species which do not synthesize GB in adequate quantities is one possible approach to overcome the negative effects of soil moisture stress on crop production (Mäkeläa et al 1996). Beneficial effect of foliar application of GB or seed treatment in mitigating DS have been reported in maize, tobacco (Nicotiana tobacum L.), soybean [Glycine max (L.) Merr] and wheat (Triticum aestivum L.) (Mäkeläa et al 1996;Agboma et al1997;Díaz-Zorita et al 2001).…”

We investigated the effects of exogenous glycinebetaine (GB) and drought stress (DS) on grain yield (GY) and production of dry matter (DM) and osmolytes in two maize (Zea mays L.) cultivars i.e. Shaandan 9 (S 9 ) and Shaandan 911 (S 911 ) during the entire growing period. Drought stress substantially reduced DM and GY but increased free proline, endogenous GB, soluble sugar and K ? concentrations in leaves of both cultivars. The DM production, GY, drought index (DI) and concentrations of these osmolytes were greater for S 9 than those for S 911 under DS. The significant differences in these parameters suggested that S 9 was more drought-tolerant as compared to S 911 . Additionally, foliar application of GB increased the concentrations of all osmolytes measured, DM and GY of both cultivars under DS. These positive responses of exogenous GB spray were more pronounced in S 911 as compared to those in S 9 . Further correlation analysis involving a number of parameters indicated that maize production was tighterly correlated with accumulation of the osmolytes measured during DS rather than wellwatered controls. Accordingly, this study demonstrated the notion of an anti-drought role of exogenous GB by osmoregulation under DS, particularly in this drought sensitive cultivar. Thus, exogenous GB application might be firstly used with drought sensitive species/cultivars when exposed to DS.

“…Since GB is considered as a metabolic end product and not degraded in plants (Ladyman et al 1980;Mäkelä et al 1996), accumulation patterns of GB at cellular and plant levels are regulated by the synthesis and transport of GB. In higher plants, GB is synthesized by a two-step oxidation of choline (Hanson and Hitz 1982).…”

The accumulation of glycinebetaine (GB) is one of the adaptive strategies to adverse salt stress conditions. Although it has been demonstrated that barley plants accumulate GB in response to salt stress and various studies focused on GB synthesis were performed, its transport mechanism is still unclear. In this study, we identified a novel gene, HvProT2, encoding Hordeum vulgare GB/proline transporter from barley plants. Heterologous expression in yeast (Saccharomyces cerevisiae) mutant demonstrated that the affinity of HvProT2 was highest for GB, intermediate for proline and lowest for gamma-aminobutyric acid. Transient expression of fusions of HvProT2 and green fluorescent protein in onion epidermal cells revealed that HvProT2 is localized at the plasma membrane. Relative quantification of mRNA level of HvProT2 using semi-quantitative reverse transcription-polymerase chain reaction analysis showed that HvProT2 is constitutively expressed in both leaves and roots, and the expression level was higher in old leaves than young leaves and roots. Moreover, we found that HvProT2 was expressed in the mestome sheath and lateral root cap cells. We discussed the possible involvement of HvProT2 for salt stress tolerance.

“…Moreover, exogenous application of betaine to leaves or roots has been shown to increase the tolerance to various stresses of several species of plants, including both natural accumulators and nonaccumulators (Mäkelä et al, 1996 andAllard et al, 1998). It has been shown that GB, when applied to foliage, is translocated from leaves to other plant parts within several hours (Mäkelä et al, 1996), where it acts as a non-toxic cytoplamic osmolyte and plays a central role in the protection of macrocomponents of plant cells, such as protein complexes and membranes, under stress conditions (Martin et al, 1997 andJagendrof &Takab, 2001). It has also been reported that exogenous glycinebetaine led to increase photosynthetic activity, leaf area, leaf water potential, water use efficiency, total chlorophyll, relative water content and grain yield when it was applied to maize, sorghum, wheat and barley (Agboma et al, 1997;Nayyar & Walia, 2004;Abd Alla Kotb, 2005;Abd Alla Kotb &Gaballah, 2007 andNawaz &Ashraf, 2007).…”

WO FIELD experiments were conducted in a sandy soil in the .......extension field in El-Kassasein, Ismailia Governorate, Egypt during 2007 and 2008 summer seasons. The work aimed to study the effect of five levels of glycinbetaine i.e., 0, 5, 10, 15, 20mM/fad(1ha=2.381fad) on the response of SC 10 maize hybrid to three rates of drip irrigation water (1.00. 0.80 and 0.60 of the estimated crop evapotranspiration, which represented 2625, 2100 and 1575 m 3 water/fad, respectively). The most important findings could be summarized as follows:Irrigation by 1575 m 3 /fad instead of 2625 m 3 /fad reduced significantly ear leaf blade area, total chlorophyll, relative water content and leaf water potential, except the content of GB in leaves which was significantly increased in both seasons. Meanwhile, increasing the level of glycinebetaine (GB) up to 15 mM/fad increased these traits and the content of GB in leaves compared with their untreated analogues.Decreasing the amount of irrigation water from 2625 to 1575 m 3 /fad reduced significantly the grain yield, protein yield and water use efficiency (IWUE). While, the relative increase percentages due to application of 15mM GB/fad compared with zero GB were 28. 47 and 25.30%, 54.53 and 47.25% and 27.61 and 25.10% for these traits in both seasons, respectively.The interaction between both studied factors showed that under moderate water stress condition (2100 m 3 /fad) without GB addition the responses of these traits were only 11.59 and 10.77 ardab/fad, 135.29 and 119.69 kg/fad and 0.773 and 0.718 kg m -3 compared with 14.31 and 13.49 ardab/fad, 195.07 and 176.25 kg/fad and 0.954 and 0.899 kg m -3 when the concentration of GB was increased to 15mM GB/fad in both seasons, respectively. Keywords: Maize, Glycinebetaine, IWUE, Drought, Evapotranspiration.Maize (Zea mays L.) is one of the most important cereal crops, which plays a critical role in animals and human feeding not only in Egypt but also in, almost, all countries. 54The total maize consumption has been increased drastically due to the overgrowing population. Improving maize productivity can be achieved by breeding high yielding varieties and by application of improved agro-techniques. Water stress-associated with high temperature is often considered to be a limiting factor in maize (Zea mays L.) grown under arid and semiarid regions. Drought has different effects on grain yield depending on the developmental stage at which it occurs. It has been reported that maize is relatively tolerant to water stress in the vegetative stage, very sensitive during the period of tasseling, silking, and pollination and moderately sensitive during the grain-filling stage Nielsen, 1987 andAbo-El-Kheir &Mekki, 2007). Increasing water stress significantly decreased relative water content, chlorophyll content, leaf water potential (Shlemmer et al., 2005 andPremachandra et al., 2008), number of grains/ear, 1000-grain weight and grain yield (Muhammad et al., 2001). Thus water stress is the most important limitation on corn productivity ...
