Anna Maria Vaira

Interessi scientifici: diagnosi e caratterizzazione molecolare di virus delle piante, in particolare con genoma ad RNA, induzione di resistenza a virus in pianta attraverso la produzione di piante transgeniche. Più recentemente si è dedicata allo studio dell’interazione virus-pianta e allo sviluppo di vettori virali adatti all’espressione in pianta di proteine esogene o all’induzione di “viral induced gene silencing” (VIGS).
