    Virus-induced gene silencing database for phenomics and functional genomics in Nicotiana benthamiana
    (American Society of Plant Biologists, John Wiley & Sons, 2018) Senthil-Kumar, Muthappa; Wang, Mingyi; Chang, Junil; Ramegowda, Venkategowda; Pozo, Olga del; Liu, Yule; Doraiswamy, Vanthana; Lee, Hee-Kyung; Ryu, Choong-Min; Wang, Keri; Xu, Ping; Eck, Joyce Van; Chakravarthy, Suma; Dinesh-Kumar, Savithramma P.; Martin, Gregory B.; Mysore, Kirankumar S.
    Virus-induced gene silencing (VIGS) is an important forward and reverse genetics method for the study of gene function in many plant species, especially Nicotiana benthamiana. However, despite the widespread use of VIGS, a searchable database compiling the phenotypes observed with this method is lacking. Such a database would allow researchers to know the phenotype associated with the silencing of a large number of individual genes without experimentation. We have developed a VIGS phenomics and functional genomics database (VPGD) that has DNA sequence information derived from over 4,000 N. benthamiana VIGS clones along with the associated silencing phenotype for approximately 1,300 genes. The VPGD has a built-in BLAST search feature that provides silencing phenotype information of specific genes. In addition, a keyword-based search function could be used to find a specific phenotype of interest with the corresponding gene, including its Gene Ontology descriptions. Query gene sequences from other plant species that have not been used for VIGS can also be searched for their homologs and silencing phenotype in N. benthamiana. VPGD is useful for identifying gene function not only in N. benthamiana but also in related Solanaceae plants such as tomato and potato. The database is accessible at http://vigs.noble.org.

    Impact of soil moisture regimes on wilt disease in tomato: current understanding
    (Elsevier B.V., Academic Press, 2018) Gupta, A; Kamalachandran, D; Longchar, B; Senthil-Kumar, Muthappa
    Biochemical, Physiological and Molecular Avenues for Combating Abiotic Stress Tolerance in Plants is a must-have reference for researchers and professionals in agronomy, plant science and horticulture. As abiotic stress tolerance is a constant challenge for researchers and professionals working on improving crop production, this book combines recent advances with foundational content, thus offering in-depth coverage on a variety of abiotic stress tolerance mechanisms that help us better understand and improve plant response and growth under stress conditions. The mechanisms explored in this book include stress perception, signal transduction and synthesis of stress-related proteins and other molecules.
