[more ▼] Crown rot disease of bananas is widespread in producing countries and is considered as the most important post-harvest disease of exported bananas. Variations of susceptibility to the disease have been noted between bananas but the origins still unknown. The biological responses of the fruit, including physiological change and disease susceptibility are controlled and regulated by gene expression. One way to understanding the reactions involved in variation of banana susceptibility to the disease in relation to their physiological state, is to study the expression of genes involved in these processes. To this purpose, crown sample previously inoculated with C. musae and showing 2 levels of susceptibility (very high and very low) were collected to be compared. Crown sample of each susceptibility level was collected at two different maturity stages: at harvest and 13 days after harvest (3 days after ripening). Collected crowns were immediately freeze-dried, an original method to conserve gene expression. cDNA-AFLP was applied on these 4 cell populations in order to highlight the differential transcription of genes whose function is "a priori" unknown. The cDNA-AFLP result was confirmed using quantitative real-time reverse transcription PCR. Various defence-related genes were identified and will be presented.

[more ▼] The antagonistic activity of two yeast strains (Pichia anomala (E.C. Hansen) Kurtzman, strain K and Candida oleophila Montrocher, strain O) against the parasitic complex responsible for banana crown rot was evaluated. The strains were applied at three different concentrations (106, 107 , 108 cfu/ml) and their efficacy tested in vivo on three separate fungi (Colletotrichum musae (Berk. & Curt.) Arx, Fusarium moniliforme Sheldon, and Cephalosporium sp.) and on a parasitic complex formed by association of these three fungi. At the concentrations used C. musae appeared to be the most pathogenic. The complex showed intermediate aggressiveness between C. musae and both other fungi. Statistically significant antagonistic effects were observed on C. musae, F. moniliforme, and the fungal complex. The highest protection level (54.4%) was observed with strain O added at 108 cfu/ml on crowns previously inoculated with the fungal complex. The level was lower when the fungi were inoculated separately. Furthermore, the antagonistic effect was strongly reinforced when strain O at 108 cfu/ml was applied 24 h before fungal complex inoculation (59.9%), as compared to its application 15 min (24.3%) or 3 h (27.3%) after fungal complex inoculation. Bananas showed increased susceptibility to the fungal complex from March to June, and this influenced the level of protection by yeast, which decreased over the same period. A strict negative correlation (R2 = 0.83) was highlighted between susceptibility of banana to crown rot and protection provided by yeast.
