    Recent advances in tomato functional genomics: utilization of VIGS
    (Springer, 2012) Sahu, Pranav Pankaj; Puranik, Swati; Khan, Moinuddin; Prasad, Manoj
    Tomato unquestionably occupies a significant position in world vegetable production owing to its world-wide consumption. The tomato genome sequencing efforts being recently concluded, it becomes more imperative to recognize important functional genes from this treasure of generated information for improving tomato yield. While much progress has been made in conventional tomato breeding, post-transcriptional gene silencing (PTGS) offers an alternative approach for advancement of tomato functional genomics. In particular, virus-induced gene silencing (VIGS) is increasingly being used as rapid, reliable, and lucrative screening strategy to elucidate gene function. In this review, we focus on the recent advancement made through exploiting the potential of this technique for manipulating different agronomically important traits in tomato by discussing several case studies.

    Crop breeding prospects in the genomic era
    (Taylor & Francis Group, 2006) Kumar, Sushil; Prasad, Manoj
    Grain/cereal crop yields need to be increased in the range of 5t ha 1, to meet the challenge of international food requirements, in the near future. Post-green revolution, conventional plant breeding and related procedures had limited success and grain crop yields have stagnated. The developments in plant genomics offer new means for genetic improvement in crop plants, such as transgenesis and marker aided precise selection of rare recombinants. A strategy, based on the use of existing genomic information on the genetic control of drought tolerance in Arabidopsis thaliana, for breeding wheat for high yields and drought tolerance is exemplified. In future plant breeding, the importance of systems approach, involving multidisciplinary contributions, to the understanding of gene structure Xenvironment interactions in respect of the concerned genes at whole plant or crop level is emphasized.
