Glandular trichomes: what comes after expressed sequence tags?
Glandular trichomes cover the surface of many plant species. They exhibit tremendous diversity, be it in their shape or the compounds they secrete. This diversity is expressed between species but also within species or even individual plants. The industrial uses of some trichome secretions and their potential as a defense barrier, for example against arthropod pests, has spurred research into t...
متن کاملProbing essential oil biosynthesis and secretion by functional evaluation of expressed sequence tags from mint glandular trichomes.
Functional genomics approaches, which use combined computational and expression-based analyses of large amounts of sequence information, are emerging as powerful tools to accelerate the comprehensive understanding of cellular metabolism in specialized tissues and whole organisms. As part of an ongoing effort to identify genes of essential oil (monoterpene) biosynthesis, we have obtained sequenc...
متن کاملExpressed Sequence Tags
Now a days, genome analysis has employed a rapid analysis tool known as expressed sequence tags. In 1983, SD Putney for the first time demonstrated the use of cDNA in identification of genome. The term expressed sequence tags (ESTs) was coined by Anthony Kerlavage at the Institute for Genomic Research. In 1991, Mark Adams used EST in relation to gene discovery and Human Genome project. cDNA or ...
متن کاملDevelopment of peltate glandular trichomes of peppermint.
Cryofixation and conventional chemical fixation methods were employed to examine the ultrastructure of developing peltate glandular trichomes of peppermint (Mentha x piperita). Our results are discussed in relation to monoterpene production and the mechanism of essential oil secretion. Peltate glands arise as epidermal protuberances (initials) that divide asymmetrically to produce a vacuolate b...
متن کاملA rapid method for isolating glandular trichomes.
A physical method is described for the rapid isolation of plant trichomes, with emphasis on stalked glandular types. The technique involved breaking frozen trichomes with powdered dry ice and collection of glandular heads by sieving from larger tissue fragments. This method was applied to several plants that bear similar stalked trichomes: geranium (Pelargonium), potato (Solanum tuberosum), tom...
