invasive growth in response to glucose limitation A growth pattern exhibited by budding haploid cells under certain growth conditions, in which cells retain the typical axial budding pattern of haploids, but become elongated and fail to separate after division; during growth on a solid substrate, this results in penetration of cells into the agar medium. An example of this process is found in Saccharomyces cerevisiae. Note that this term should not be used to describe the invasion of host tissues by pathogenic organisms, which is described by the biological process term 'entry into host ; GO:0044409', nor should it be used to describe growth of diseased cells of an organism into the surrounding normal tissue, which is outside of the scope of GO.
