major project objectives: 1. Xcm avirulence (avr) genes as SAR triggers Characterise F1 progeny in terms of expression levels of SAR markers and tolerance to fungal infection using Verticillium and Altemaria 2. Promoters Screen fis-gus progeny for gus expression induced by fungal infection to establish the sensitivity of tis promoter to fungal induction. Establish gus expression after treatment with chemical SAR inducers e.g. BTH. 3. Screen other transform ants for transgene presence.
