For accurate and reliable gene expression results, normalization of real-time PCR data is required against a control gene, which displays highly uniform expression in living organisms during various phases of development and under different environmental conditions. We assessed the gene expression of 10 frequently used housekeeping genes, including 18S(More)
The basic leucine (Leu) zipper (bZIP) proteins compose a family of transcriptional regulators present exclusively in eukaryotes. The bZIP proteins characteristically harbor a bZIP domain composed of two structural features: a DNA-binding basic region and the Leu zipper dimerization region. They have been shown to regulate diverse plant-specific phenomena,(More)
F-box proteins constitute a large family in eukaryotes and are characterized by a conserved F-box motif (approximately 40 amino acids). As components of the Skp1p-cullin-F-box complex, F-box proteins are critical for the controlled degradation of cellular proteins. We have identified 687 potential F-box proteins in rice (Oryza sativa), the model(More)
Important developmental processes in both plants and animals are partly regulated by genes whose expression is modulated at the post-transcriptional level by processes such as RNA interference (RNAi). Dicers, Argonautes and RNA-dependent RNA polymerases (RDR) form the core components that facilitate gene silencing and have been implicated in the initiation(More)
Auxin exerts pleiotropic effects on plant growth and development by regulating the expression of early auxin-responsive genes of auxin/indoleacetic acid (Aux/IAA), small auxin-up RNA, and GH3 classes. These genes have been studied extensively in dicots like soybean and Arabidopsis. We had earlier characterized a cDNA of the first monocot member of Aux/IAA(More)
We report here the isolation and characterization of three SOMATIC EMBRYOGENESIS RECEPTOR KINASE (TaSERK) genes from wheat. TaSERKs belong to a small family of receptor-like kinase genes, share a conserved structure and extensive sequence homology with previously reported plant SERK genes. TaSERK genes are in general auxin inducible and expressed during(More)
Small auxin-up RNAs (SAURs) are the early auxin-responsive genes represented by a large multigene family in plants. Here, we report the identification of 58 OsSAUR gene family members from rice (Oryza sativa japonica cv Nipponbare), the model monocot plant, by a reiterative database search and manual reannotation; 2 of these are pseudogenes. The coding(More)
Auxin influences growth and development in plants by altering gene expression. Many auxin-responsive genes have been characterized in Arabidopsis in detail, but not in crop plants. Earlier, we reported the identification and characterization of the members of the GH3, Aux/IAA and SAUR gene families in rice. In this study, whole genome microarray analysis of(More)
Plant cells possess two more genomes besides the central nuclear genome: the mitochondrial genome and the chloroplast genome (or plastome). Compared to the gigantic nuclear genome, these organelle genomes are tiny and are present in high copy number. These genomes are less prone to recombination and, therefore, retain signatures of their age to a much(More)
Quantitative trait loci (QTL) analysis was conducted for pre-harvest sprouting tolerance (PHST) in bread wheat for a solitary chromosome 3A, which was shown to be important for this trait in earlier studies. An intervarietal mapping population in the form of recombinant inbred lines (RILs) developed from a cross between SPR8198 (a PHS tolerant genotype) and(More)
