Abstract

         Insect galls are atypical plant tissues induced by the invasion of insects. Studies on insect galls demonstrated the specificity between insect and host plant, the diversity of gall morphologies, and the evolutionary divergence of gall types. Several hypotheses were suggested for gall formation, which concerning plant defense, microenvironment, and nutrition. In Taiwan, Machilus (Lauraceae) is the genus that have most documented gall forming records. Our group have analyzed the photosynthesis ability and the nutrient flow in the gall tissues of Machilus and other plant species, showing a heterotrophic characteristic of gall and further supporting the nutrition hypothesis. Our recent examination on gall transcriptome also reveals the molecular regulation of gall tissue. Another interesting topic in cecidology is that the exogenous phytohormones from insect larvae may participate in manipulating plant gall formation, but only few literatures were able to provide evidence in supporting this suggestion. Expressional changes in the hormone-associated genes present in Machilus and other researches might consolidate this suggestion in an alternative aspect.
