Cell wall composition and transcriptomics in stem tissues of stinging nettle (Urtica dioica L.): Spotlight on a neglected fibre crop.

ABSTRACT: Stinging nettle (Urtica dioica L.) produces silky cellulosic fibres, as well as bioactive molecules. To improve the knowledge on nettle and enhance its opportunities of exploitation, a draft transcriptome of the "clone 13" (a fibre clone) is here presented. The transcriptome of whole internodes sampled at the top and middle of the stem is then compared with the core and cortical tissues sampled at the bottom. Young internodes show an enrichment in genes involved in the biosynthesis of phytohormones (auxins and jasmonic acid) and secondary metabolites (flavonoids). The core of internodes collected at the bottom of the stem is enriched in genes partaking in different aspects of secondary cell wall formation (cellulose, hemicellulose, lignin biosynthesis), while the cortical tissues re
