摘 要：Seedless fruits have high consumer appeal and have made seeded varieties obsolete in some *** seedless apple varieties,core tissues which normally contain the seed can be unpalatable,reducing the seedless *** are accessory fruit with edible flesh derived from hypanthial tissue–a floral tube fused to a compound *** we show that through suppression of AGAMOUS-like carpel identity genes and hormone induced fruit set,it is possible to generate coreless and therefore seedless *** of AGAMOUS-like genes increased petal whorls and fully eliminated carpel *** with a combination of gibberellin,cytokinin and auxin,rather than single treatments,were required for fruit initiation in these *** analysis of agamous RNAi lines suggested conservation of AGAMOUS-dependent gene networks between apple and *** the absence of all sexual tissues,the developing fruit continues to grow and follow a ripening process similar to that of a regular *** coreless phenotype offers a new concept for pipfruit consumers improving convenience and reducing food waste.
