Journal ArticleDOI
Isolation, characterization and expression studies of resistance gene candidates (RGCs) from Zingiber spp.
R. Aswati Nair,George Thomas +1 more
TL;DR: The isolation and characterization of RGCs from ginger and its wild relatives are reported for the first time, which will serve as a potential resource for future improvement of this important vegetatively propagated spice crop.
Journal ArticleDOI
Correlation of Phenylalanine ammonia lyase (PAL) and Tyrosine ammonia lyase (TAL) activities to phenolics and curcuminoid content in ginger and its wild congener, Zingiber zerumbet following Pythium myriotylum infection
TL;DR: Results are indicative of phenylpropanoid pathway regulation in a manner such that the induced defense metabolites contribute to restrict pathogen invasion in the resistant wild taxon.
Journal ArticleDOI
Molecular Characterization of an Oomycete-Responsive PR-5 Protein Gene from Zingiber zerumbet
TL;DR: A member of the pathogenesis-related protein group 5 (PR-5) gene family is identified in Z. zerumbet that is expressed constitutively but upregulated in response to infection by P. aphanidermatum and elucidation of the molecular mechanism of ZzPR5 may provide important insight toward engineering soft rot resistance into the obligatory asexual ginger.
Journal ArticleDOI
Corosolic acid content and SSR markers in Lagerstroemia speciosa (L.) Pers.: A comparative analysis among populations across the Southern Western Ghats of India
K.S. Jayakumar,J.S. Sajan,R. Aswati Nair,P. Padmesh Pillai,S. Deepu,R. Padmaja,Agarwal A,A.G. Pandurangan +7 more
TL;DR: It is concluded that the observed variation in CRA content in natural populations of the species depends more on the genetic background and less on edaphic factors.
Journal ArticleDOI
Metabolic profiling of Zingiber zerumbet following Pythium myriotylum infection: investigations on the defensive role of the principal secondary metabolite, zerumbone.
TL;DR: The mechanistic basis of zerumbone’s antagonistic action on P. myriotylum growth involved the induction of aberrant morphology including severe hyphal deformities and membrane disruption and could expedite the development of appropriate strategies for biocontrol of Pythium spp.
