Redirection of cytosolic or plastidic isoprenoid precursors elevates terpene production in plants

Article Abstract:

High-level terpene production in tobacco plants is engineered by diverting carbon flow from cytosolic or plastidic isopentenyl diphosphate through over expression in compartment of an avian farnesyl diphosphate synthase and an appropriate terpene synthase. This strategy increased synthesis of the sesquiterpenes patchoulol and amorpha-4,11-diene more than 1,000-fold, and monoterpene limonene 10-30 fold, and seems equally suited to generating higher levels of other terpenes for research, industrial production or therapeutic applications.

RNAi for insect-proof plants

Article Abstract:

The RNA interference (RNAi) induced by hairpin RNAs can be used for managing crop pests like coleopteran and lepidopteran. Different studies show that plant-delivered silencing of insect-detoxifying genes might become a powerful strategy for controlling insect pests.
