Pigeonpea (Cajanus cajan) is an important grain legume of the Indian subcontinent, South-East Asia and East Africa. More than eighty five percent of the world pigeonpea is produced and consumed in India where it is a key crop for food and nutritional security of the people. Here we present the first draft of the genome sequence of a popular pigeonpea(More)
Chickpea (Cicer arietinum L.), an important grain legume crop of the world is seriously challenged by terminal drought and salinity stresses. However, very limited number of molecular markers and candidate genes are available for undertaking molecular breeding in chickpea to tackle these stresses. This study reports generation and analysis of comprehensive(More)
Chickpea (Cicer arietinum L.) is an important legume crop in the semi-arid regions of Asia and Africa. Gains in crop productivity have been low however, particularly because of biotic and abiotic stresses. To help enhance crop productivity using molecular breeding techniques, next generation sequencing technologies such as Roche/454 and Illumina/Solexa were(More)
To develop an alternative genetic transformation system that is not dependent on an antibiotic selection strategy, the phosphomannose isomerase gene (pmi) system was evaluated for producing transgenic plants of chickpea (Cicer arietinum L.). A shoot morphogenesis protocol based on the thidiazuron (TDZ)-induced shoot morphogenesis system was combined with(More)
The AP2/ERF family is one of the largest transcription factor gene families that are involved in various plant processes, especially in response to biotic and abiotic stresses. Complete genome sequences of one of the world’s most important pulse crops chickpea (Cicer arietinum L.), has provided an important opportunity to identify and characterize(More)
With the availability of complete genome sequences of several organisms, the focus has shifted from structural genomics to functional genomics, specifically in plants where the complete genomic sequences are becoming available i.e., Arabidoposis and rice. Agrobacterium mediated transformation which is exploited for transgenic technology is also being used(More)
Isolation and characterization of promoters are important in understanding gene regulation and genetic engineering of crop plants. Earlier, a pentatricopeptide repeat protein (PPR) encoding gene (At2g39230), designated as Lateral Organ Junction (LOJ) gene, was identified through T-DNA promoter trapping in Arabidopsis thaliana. The upstream sequence of the(More)
Adventive polyembryony is a form of apomixis where sporophytic cells of the ovule directly give rise to embryos nourished by the endosperm of autonomous or sexual origin. Molecular basis of adventive embryony is poorly understood. This is the first report of transcriptome analysis of developing ovules during citrus nucellar embryo initiation. Suppression(More)
A T-DNA based promoter trapped mutant has led to the identification of a novel lateral organ junction specific promoter upstream of the pentatricopeptide repeat (PPR) protein coding gene LOJ in Arabidopsis thaliana by our laboratory. Various in silico based prediction tools are employed to characterize the upstream sequence of the LOJ gene. Out of numerous(More)
The NAC (NAM, ATAF and CUC) proteins are plant-specific transcription factors implicated in development and stress responses. In the present study 88 pigeonpea NAC genes were identified from the recently published draft genome of pigeonpea by using homology based and de novo prediction programmes. These sequences were further subjected to phylogenetic,(More)
