The study of these is called cecidology, and one example can be caused by the invasion ofÂ haustoria into the host tissue.
The filz variants of these structures result in hairy tissues, whereas the causative insects become enclosed within the tissue in the "covering" form of these structures. The study of these is called cecidology, and one example can be caused by the invasion ofÂ haustoria into the host tissue. Another type of these occurs due to genes encoded on the Fi plasmid, and results in planar, fan like structures. Another of these is induced whenÂ Agrobacterium tumefaciensÂ releases its Ti plasmid into the host. Most of these occur due to activation of genes that cause overproduction of phytohormones in the host. For 10 points, identify these (*) neoplasias that occur when plant tissues undergo uncontrolled growth, whose most well known variety is the "crown" type.
