Transcriptomic and metabolomic analysis reveal that fullerol improves drought tolerance in Brassica napus L.

The fullerenes, a kind of carbon nanoparticles, have potential for enhanced stress tolerance in plants. While the positive effects of polyhydroxy fullerene—fullerol on plants in response to drought at the physiological level have been documented, the molecular mechanism in Brassica napus are not entirely understood. In this study, exogenous fullerol was applied to the leaves of B. napus seedlings given drought. The leaves of B. napus seedlings in each treatment (sufficient water condition, drought, and drought combined with fullerol) were used to conduct the molecular mechanism using transcriptomic analysis. Comparative gene expression profiling analysis of RNA-seq data for leaves of Brassica napus seedlings under different treatment (well-watered, drought, drought applied with fullerol).
