BACKGROUND 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(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)

Chickpea (Cicer arietinum) is the second most widely grown legume worldwide and is the most important pulse crop in the Indian subcontinent. Chickpea productivity is adversely affected by a large number of biotic and abiotic stresses. MicroRNAs (miRNAs) have been implicated in the regulation of plant responses to several biotic and abiotic stresses. This(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)
Genetic diversity and relationships within and among members of the primary gene pool of chickpea, including 38 accessions of Cicer arietinum, six of C. reticulatum,, and four of C. echinospermum, were investigated using 31 ISSR markers. The study revealed moderate diversity, detecting 141 fragments, of which 79 (56%) were polymorphic. Averages were 0.125(More)
The Arabidopsis thaliana promoter trap line GUS-650 showing uidA reporter gene expression specifically in mature embryo sacs was found to carry transfer DNA (T-DNA) insertion in the 5′ untranslated region (UTR) of At3g17150. At3g17140 and At3g17150 are a pair of head-to-head-oriented genes separated by a 668-bp intergenic region encoding for a putative(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)
BACKGROUND Hypericum is a well-known plant genus in herbal medicine. Hypericum mysorense (Family: Hypericaceae), a plant belonging to the same genus, is well known in folklore medicine for its varied therapeutic potential. OBJECTIVE The aim of the present study was to investigate the different parts of the plant for antioxidant and hepatoprotective(More)
Identification and characterization of regulatory elements, such as enhancers, require designing of specialized plant transformation vector to testify its unique features of position and orientation-independent core-promoter activation. Very few plant transformation vectors are available till date for identification of enhancer elements in plant promoters.(More)
T-DNA insertional based strategies have been successfully employed to identify genes and promoters in plants. A promoter trap mutant line anth85, carrying T-DNA insertion in the 5′-UTR region of the Atprx18 (At2G24800) gene was found to exhibit GUS gene expression characteristically in anthers and cotyledons of Arabidopsis. The homozygous mutant, anth85(More)
