Gene silencing: concepts, applications, and perspectives in woody plants

Silenciamento gênico: conceitos, aplicações e perspectivas em plantas lenhosas

RNA interference, transcriptional gene silencing, virus induced gene silencing, and micro RNAs comprise a series of mechanisms capable of suppressing gene expression in plants. These mechanisms reveal similar biochemical pathways and appear to be related in several levels. The ability to manipulate gene silencing has produced transgenic plants able to switch off endogenous genes and invading nucleic acids. This powerful biotechnological tool has provided plant breeders and researchers with great opportunity to accelerate breeding programs and developmental studies in woody plants. This research work reports on gene silencing in woody plants, and discuss applications and future perspectives.
