Arabinogalactan-proteins (AGPs) are highly glycosylated proteins (glycoproteins) found in the cell walls of plants. AGPs account for only a small portion wall, usually no more than 1% dry mass primary wall. members hydroxyproline-rich glycoprotein (HRGP) superfamily that represent large and diverse group wall proteins. have attracted considerable attention due to their complex structures potent...

Quantitative and qualitative changes in total leaf soluble proteins were determined in a spring cv. Zagross and in a winter cv. Azar 2 cultivar of allohexaploid wheat (Triticum aestivum L.) exposed to 4°C for two weeks. The data obtained were used to test whether these different genotypes of wheat responded differentially to cold treatment. Seedlings were grown in a controlled growth chamber fo...

Drought is one of the most important factors limiting crop yields around the world. Drought stress in plants, the change (increase or decrease) in the production of plant proteins. This research was carried out using bread wheat genotypes. For evaluation of leaf protein pattern in wheat, 10 genotypes were assayed with 3 replications under irrigated (non-stress) and rain-fed (stress) conditions....

To investigate the intercellular control of glutathione synthesis and its influence on leaf redox state in response to short-term chilling, genes encoding gamma-glutamylcysteine synthetase (gamma-ECS) and glutathione synthetase (GSH-S) were cloned from maize (Zea mays) and specific antibodies produced. These tools were used to provide the first information on the intercellular distribution of g...

in a pot experiment the effect of water stress on the proteins and proline amino acid content of jam, kurosh, pirooz chickpea cultivars (cicer arientinum) were evaluated using a complete block design with factorial treatments inducing cultivars and watering periods, three, six and nine day intervals in three replications. soluble protein and free proline content of the leaf and the root were me...

Despite a high nitrate uptake capacity, the nitrogen use efficiency (NUE) of oilseed rape is weak due to a relatively low N remobilization from vegetative (mostly leaves) to growing parts of the plant. Thus, this crop requires a high rate of N fertilization and leaves fall with a high N content. In order to reduce the rate of N fertilization and to improve the environmental impact of oilseed ra...

Cassava (Manihot esculenta Crantz) wild relatives remain a largely untapped potential for genetic improvement. However, the domestication syndrome phenomena from wild species to cultivated cassava remain poorly understood. The analysis of leaf anatomy and photosynthetic activity showed significantly different between cassava cultivars SC205, SC8 and wild relative M. esculenta ssp. Flabellifolia...

Drought stress was generated by PEG 6000. Water potentials were: zero as the control, and –0.15, –0.49, –1.03, and –1.76 MPa as treatments. After 24-h treatment the total soluble protein content of 2 maize (Zea mays L.) cultivars (704 and 301) was determined and SDS-PAGE gel electrophoresis in the first dimension was performed. By decreasing water potentials, total soluble protein content first...

The wheat leaf proteome was mapped and partially characterized to function as a comparative template for future wheat research. In total, 404 proteins were visualized, and 277 of these were selected for analysis based on reproducibility and relative quantity. Using a combination of protein and expressed sequence tag database searching, 142 proteins were putatively identified with an identificat...
