Transcriptome profile analysis of cell proliferation molecular processes during multicellular trichome formation induced by tomato Wov gene in tobacco

Abstract

Trichomes, developing from the epidermis of nearly all terrestrial plants, provide good protection from environmental stress. Regulation of trichomes in Rosids has been well characterized. However, little is known about the cell proliferation molecular processes during multicellular trichome formation in Asterids. Ectopic expression of Wov in tobacco and potato induces much more trichome formation than wild type. To gain new insights into the underlying mechanisms during the processes of these trichomes formation, RNA-seq was employed for the young primary leaf tissues in Wov transgenic and wild-type tobacco. We identified differentially expressed genes which are related to various biological processes and molecular functions. Here, we provide details of experimental methods, RNA-seq data (available at Gene Expression Omnibus database under GSE72310). Our data provide new insight into the molecular processes controlling multicellular formation in tobacco.
