During the efficient genetic transformation of plants with the gene of interest, some selectable marker genes are also used in order to identify the transgenic plant cells or tissues. Usually, antibiotic- or herbicide-selective agents and their corresponding resistance genes are used to introduce economically valuable genes into crop plants. From the(More)
The p68, a prototypic member of DEAD-box protein family, is involved in pre-mRNA splicing, RNA-induced silencing and transcription regulation. However, the role of plant p68 in stress tolerance and molecular targets responsible for this has not been reported. Here, we report the isolation and characterization of salinity-induced pea p68 (Psp68). The(More)
Coping with salinity-induced reduction in crop yield is essential for food security. Human leukocyte antigen-B associated transcript 1 (BAT1) also called as UAP56 is a DExD/H-box protein involved in messenger RNA (mRNA) splicing. Function of plant homologue of BAT1, especially its involvement in stress tolerance, has not been reported so far. Here, we(More)
Current soil management strategies are mainly dependent on inorganic chemical-based fertilizers, which caused a serious threat to human health and environment. The exploitation of beneficial microbes as a biofertilizer has become paramount importance in agriculture sector for their potential role in food safety and sustainable crop production. The(More)
Biological nitrogen fixation (BNF) is highly effective in the field and potentially useful to reduce adverse effects chemical fertilisers. Here, Azotobacter species were selected via phenotypic, biochemical and molecular characterisations from different rice fields. Acetylene reduction assay of Azotobacter spp. showed that Azotobacter vinelandii (Az3) fixed(More)
Beneficial microorganisms have been considered as an important tool for crop improvement. Native isolates of Azospirillum spp. were obtained from the rhizospheres of different rice fields. Phenotypic, biochemical and molecular characterizations of these isolates led to the identification of six efficient strain of Azospirillum. PCR amplification of the nif(More)
The SUV3 (suppressor of Var 3) gene encodes a DNA and RNA helicase, which is localized in the mitochondria. Plant SUV3 has not yet been characterized in detail. However, the Arabidopsis ortholog of SUV3 (AT4G14790) has been shown to be involved in embryo sac development. Previously, we have reported that rice SUV3 functions as DNA and RNA helicase and(More)
This study demonstrates a dose-dependent response of Trichoderma harzianum Th-56 in improving drought tolerance in rice by modulating proline, SOD, lipid peroxidation product and DHN / AQU transcript level, and the growth attributes. In the present study, the effect of colonization of different doses of T. harzianum Th-56 strain in rice genotypes were(More)
The present study provides evidence of a unique function of RGG1 in providing salinity stress tolerance in transgenic rice without affecting yield. It also provides a good example for signal transduction from the external environment to inside for enhanced agricultural production that withstands the extreme climatic conditions and ensures food security. The(More)
Senescence is a very complex process characterized by a highly regulated series of degenerative events which include changes in cell structure, metabolism and gene expression. In animals, one of the indicators of senescence is telomere shortening. In plants, this aspect is more puzzling because telomere shortening is not always correlated with senescence.(More)
