arachis repens/proline

The groundnut, Arachis hypogaea seedlings, when grown in pot cultures for 10-25 days at 25, 50, 100 microM CdCl2, showed a marked decline in growth compared to control. Similar trend was observed for nitrate reductase (NR) and nitrite reductase (NiR) activities whereas proline, peroxidase (POD) and

Interactions between salivary glycoproteins and many oral bacteria have been shown to depend on O-linked glycans on salivary glycoproteins. Basic proline-rich proteins form the largest group of proteins within human parotid saliva. In the present study human parotid salivary glycoproteins were

Phytotoxicity of cadmium on growing Arachis hypogaea L. seedlings was studied. Seeds were exposed to 25, 50, and 100 micromol/L CdCl2 concentrations, for a period of 10, 15, 20 and 25 d. The extent of damage to chlorophyll, protein, proline, nitrate and nitrite reductase, antioxidant enzyme activity

Drought, salinity and extreme temperatures are the most common abiotic stresses, adversely affecting plant growth and productivity. Exposure of plants to stress activates stress signalling pathways that induce biochemical and physiological changes essential for stress acclimation. Stress tolerance

Peanut, an important oilseed crop, is gaining priority for the development of drought tolerant genotypes in recent times, since the area under drought is constantly on the rise. To achieve this, one of the important strategies is to genetically engineer the ruling peanut varieties using

The SbASR-1 gene, cloned from a halophyte Salicornia brachiata, encodes a plant-specific hydrophilic and stress responsive protein. The genome of S. brachiata has two paralogs of the SbASR-1 gene (2549 bp), which is comprised of a single intron of 1611 bp, the largest intron of the abscisic acid

Polyamines play an important role in stress response. In the pathway of polyamines synthesis, S-adenosylmethionine decarboxylase (SAMDC) is one of the key enzymes. In this study, a full length cDNA of SAMDC (AhSAMDC) was isolated from peanut (Arachis hypogaea L.). Phylogenetic analysis revealed high

Improving drought tolerance through gene manipulation has been of importance for modern agriculture, which requires identification and validation of candidate genes. Prospecting candidate genes from drought adapted crop species is of immense significance. To identify candidate stress responsive

A peanut cDNA phage surface display library was constructed and screened for the presence of IgE-binding proteins. We used a serum from a peanut-sensitized individual with a low specific IgE level to peanut extract and suffering from mild symptoms after peanut ingestion. A total of 10(11) cDNA

Drought is one of the major environmental constraints affecting the crop productivity worldwide. One of the agricultural challenges today is to develop plants with minimized water utilization and reduced water loss in adverse environmental conditions. Epicuticular waxes play a major role in

To better understand movement of systemic fungicides in peanut (Arachis hypogaea), three terminal, fully expanded leaves of primary lateral branches of 'Tifrunner' peanut were treated with prothioconazole + tebuconazole (Provost, 0.29 kg a.i./ha), azoxystrobin (Abound, 0.31 kg a.i./ha), or

Neither 4-methyleneglutamine nor 4-methyleneglutamic acid were found in free or bound form in ungerminated peanut seeds (Arachis hypogaea L.). Both, however, were formed soon after germination; whereas, 4-methyleneglutamic acid appeared slightly before 4-methyleneglutamine, the former remained at a

Human parotid salivary glycoproteins separated by gradient sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) and electroblotted onto nitrocellulose have been investigated using a battery of biotinylated lectin probes of characterized sugar specificity. Lectin binding, detected on

Drought stress has adverse effects on growth, water relations, photosynthesis and yield of groundnut. WRKY transcription factors (TFs) are the plant-specific TFs which regulate several down-stream stress-responsive genes and play an essential role in plant biotic and abiotic stress responses. We

Salinity and drought are main threat to agriculture productivity, to avoid further losses it is necessary to improve the genetic material of crops against these stresses In this present study, AtNHX1, a vacuolar type Na(+)/H(+) antiporter gene driven by 35S promoter was introduced into groundnut
