A total of 12,080 sequences, including 5,851 transcriptome contigs developed at NBRI and 5,002 singlets and 1,227 contigs assembled from 13,201 expressed sequence tags (ESTs) of Jatropha curcas from National Center for Biotechnology Information database were used to search for simple sequence repeats (SSRs). Seven hundred and two sequences containing 786(More)
A synthetic gene coding for the surface glycoprotein (G protein) of rabies virus was strategically designed to achieve high-level expression in transgenic plants. The native signal peptide was replaced by that of the pathogenesis related protein, PR-S of Nicotiana tabacum. An endoplasmic reticulum retention signal was included at C-terminus of the G(More)
Genes that code for proteins expressed at high and low levels in plants were classified into separate data sets. The two data sets were analysed to identify the conserved nucleotide sequences that may characterize genes with contrasting levels of expression. The AUG context that characterized the highly expressed genes is (A/C)N2AAN3(A/T)T(A/C)(More)
Cotton (Gossypium hirsutum L.) is a major fiber crop that is grown worldwide; it faces extensive damage from sap-sucking insects, including aphids and whiteflies. Genome-wide transcriptome analysis was performed to understand the molecular details of interaction between Gossypium hirsutum L. and sap-sucking pests, namely Aphis gossypii (Aphid) and Bemisia(More)
Transcription factors (TF) play a crucial role in regulating gene expression and are fit to regulate diverse cellular processes by interacting with other proteins. A TF named calmodulin binding transcription activator (CAMTA) was identified in Arabidopsis thaliana (AtCAMTA1-6). To explore the role of CAMTA1 in drought response, the phenotypic differences(More)
High-throughput genotyping arrays provide a standardized resource for plant breeding communities that are useful for a breadth of applications including high-density genetic mapping, genome-wide association studies (GWAS), genomic selection (GS), complex trait dissection, and studying patterns of genomic diversity among cultivars and wild accessions. We(More)
Cotyledonary nodes taken alongwith shoot apex from seedlings of cotton (G. hirsutum) proliferated into shoots on nutrient agar medium supplemented with cytokinins. In the presence of optimal plant growth regulators, low light intensity enhanced the number of shoots initiated per explant in cotton. An average of 33.5 +/- 2.9 shoots were obtained from a(More)
A synthetic bidirectional expression module was constructed by placing a computationally designed minimal promoter sequence on the 5' and 3' sides of a transcription activation module. The activation of transcription from the unidirectional and bidirectional promoters constructed from the same sequence elements was evaluated by using the reporter genes gusA(More)
Nucleotide positions conserved on the 3' side of the initiator codon ATG and the corresponding N-terminal amino acid residues in a number of highly abundant plant proteins were identified by computational analysis of a dataset of highly expressed plant genes. The reporter genes uidA and gfp were modified to introduce these features. Insertion of GCT TCC TCC(More)
