“…Ahn et al [52,53] reported that thiamin treatment induced systemic acquired resistance in plants. Meanwhile, the exogenous application of thiamin has been shown to counteract the harmful effects of salinity on growth [54], as well as to confer resistance to fungal, bacterial, and viral infections in rice ( Oryza sativa ), Arabidopsis , and certain vegetable crop species [55]. The role of thiamin biosynthetic enzymes in mediating the response to P. sojae warrants further investigation.…”

BackgroundPhytophthora sojae causes soybean root and stem rot, resulting in an annual loss of 1-2 billion US dollars in soybean production worldwide. A proteomic technique was used to determine the effects on soybean hypocotyls of infection with P. sojae.ResultsIn the present study, 46 differentially expressed proteins were identified in soybean hypocotyls infected with P. sojae, using two-dimensional electrophoresis and matrix-assisted laser desorption/ionization tandem time of flight (MALDI-TOF/TOF). The expression levels of 26 proteins were significantly affected at various time points in the tolerant soybean line, Yudou25, (12 up-regulated and 14 down-regulated). In contrast, in the sensitive soybean line, NG6255, only 20 proteins were significantly affected (11 up-regulated and 9 down-regulated). Among these proteins, 26% were related to energy regulation, 15% to protein destination and storage, 11% to defense against disease, 11% to metabolism, 9% to protein synthesis, 4% to secondary metabolism, and 24% were of unknown function.ConclusionOur study provides important information on the use of proteomic methods for studying protein regulation during plant-oomycete interactions.

“…Exogenous application of non-enzymatic antioxidative compounds were found to be very effective in reducing electrolyte leakage in salt stressed maize plants. Sayed and Gadallah (2002) showed that root or shoot applied thiamine improved growth, which was found to be associated with thiamine-induced reduced membrane injury and increased leaf RWC. Excess lipid oxidation will eventually result in membrane damage.…”

This experiment was conducted at the National Research Centre, Dokki, Cairo, Egypt during 2006 and 2007 winter season to evaluate the effects of spraying with tryptophan (TP) and nicotinic acids (NA) on onion plants grown under varying degree of salinity stress (irrigation water with 3000 and 6000 ppm salinity) as compared to tap water (300 ppm) irrigation. Irrigation by high salinity water decreased the number of leaves, mean bulb diameter, fresh and dry weight of bulb and whole plant. Foliar application of TP and NA significantly increased the top height and fresh weight, and bulb dry weight. The above beneficial effects were greater in the plants sprayed with NA as compared to those of the plants received TP spray. At the lower salinity level (3000 ppm), TP was more effective than NA in mitigating the negative effects of salinity stress. At the high salinity stress (6000 ppm), however, the converse was evident. The electrolyte leakage (EL) was not influenced by 3000 ppm salinity irrigation water as compared to that of the plants which received tap water (300 ppm) irrigations. However, it increased significantly in the plants irrigated by 6000 ppm salinity water. Lipid peroxidation (LP) and EL were significantly lower in the plants sprayed with TP or tapwater. In addition, spraying of NA or TP increased the plant growth and biomass weight. Therefore, the above foliar sprays appear to mitigate the negative effects of increased salinity.

“…In line with previous studies on syngonium (Abd El-Aziz et al 2007), gladiolus (Hashish et al 2015;Sajjad et al 2015) and tomato (Farouk et al 2012), Th application increased the nutrient contents in coriander and fenugreek. In a study on sunflower, the contents of toxic ions Na + , Ca2 + and Clwere significantly lower, while cytoplasmic K + content, which is essential for survival in stress condition, were higher in Th-treated plants (Sayed & Gadallah 2002). It seems that more root expansion in Th-treated plants can be a possible reason for better absorption of nutrients in coriander and fenugreek.…”

“…Moreover, the accumulation of some osmo-regulators, such as soluble sugars and free amino acids may increase in response to Th application. This phenomenon, by changing the water potential of plants, can increase the turgor pressure, which is needed for cell expansion and thereby plant growth (Sayed & Gadallah 2002).…”

“…It has been reported that the main function of antioxidants, such as some vitamins, is the protection of cell membranes and their binding transporter proteins (H + -ATP-ase pumps) against the reactive oxygen species and more absorption and translocation of minerals (Mady 2009). Soluble sugar accumulation, which can protect the integrity of the cell membranes might be a reason for membrane protection in the Th-treated plants (Sayed & Gadallah 2002). Some researchers suggest that it is possible that vitamins foliar spray can stimulate the root secretion of organic acids into the soil that increase the nutrients' solubility in rhizosphere zone, which leads to uptake of more nutrients by the plant (Abd El-Aziz et al 2007).…”

This study was aimed to investigate the effect of thiamine (Th) foliar application on some morphophysiological aspects in coriander and fenugreek. Three levels of Th (250, 500 and 750 ppm) plus control treatment (distilled water) were studied under controlled greenhouse conditions. All the levels of Th, in particular the concentration of 500 ppm, increased the vegetative growth of coriander. 1000-grain weight, contents of nitrogen and phosphorus, carotenoid and chlorophyll b contents were the highest at a concentration of 750 ppm. Fenugreek vegetative growth also responded positively to the application of Th especially at a concentration of 750 but also 500 ppm increased the content of leaf nitrogen, chlorophyll b, carotenoids, phenolics and antioxidant activity. Overall, the performance of coriander and fenugreek was improved by the application of Th foliar at all levels.
