Plant growth and yield are affected by many abiotic stresses like salinity, drought, cold and heavy metal; these stresses trigger up and down-regulate several genes through various transcription factors (TFs). Transcription factor binding motifs (TFBMs), located in the upstream region of the genes, associate with TFs to regulate the gene expression. Many(More)
Maize (Zea mays L. cv. Ganga-5) seedlings were grown in the presence of ferulic acid (0.5 – 3.0 mM) for 8 d. Treatment with ferulic acid considerably decreased shoot and root length, increased the activity of peroxidase, catalase and indole-3-acetic acid (IAA) oxidase and decreased the activity of polyphenol oxidase. The increased activity of peroxidase(More)
Ferulic acid was tested for its effect on the growth of root and shoot, fresh and dry weights, and hydrolytic enzyme activities of germinating maize seeds. The results showed that root growth was inhibited more than shoot growth. A significant reduction in the activities of hydrolytic enzymes was also observed, which reflects a mechanism of action for the(More)
Brassica juncea L. eight-day-old seedlings treated with various concentrations (50–200 µM) of copper for 48 h accumulated Cu more in the roots than in leaves. Accumulation of copper resulted in more active lipid peroxidation and depletion of glutathione (GSH) pools in both roots and shoots, which was attributed to copper-induced additional oxidative stress.(More)
Rice lines derived from wild species and mutants can serve as a good resource for favorable alleles for heat tolerance. In all, 48 stable lines including 17 KMR3/O. rufipogon introgression lines (KMR3 ILs), 15 Swarna/O. nivara ILs (Swarna ILs) along with their parents, Nagina 22 (N22) and its 4 EMS induced mutants and 7 varieties were evaluated for heat(More)
Rice blast is a devastating fungal disease, which limits rice production severely. To identify novel alleles of blast resistant gene, Pi54, and to understand its diversity exist among wild Oryza species and landraces sequence-based allele mining strategy was employed. In this study, sixteen Pi54 alleles were sequenced from landraces and wild Oryza species(More)
Investigations were carried out on a salt tolerant (Manak, H77-216) and a comparatively salt sensitive (ICPL 88039) genotypes of pigeonpea (Cajanus cajan L. Millsp.) under NaCl, B and NaCl + B stress to examine the acclimatory response to H2O2, glutathione and H2O2 + glutathione through their effect on mineral nutrition, morpho-physiological parameters and(More)
Pib is one of significant rice blast resistant genes, which provides resistance to wide range of isolates of rice blast pathogen, Magnaporthe oryzae. Identification and isolation of novel and beneficial alleles help in crop enhancement. Allele mining is one of the best strategies for dissecting the allelic variations at candidate gene and identification of(More)
