(n.) A band of white matter in the wall of fourth ventricle of the brain.
Example Sentences:
(1) Therefore, lg1 mutant sectors not only fail to induce ligule and auricle, but are also disrupting some form of intercellular communication that is necessary for the normally coordinated development of the ligular region.
(2) The ligule and auricles separate the blade and sheath of normal maize leaves and are absent in liguleless-1 (lg1) mutant leaves.
(3) The Kn1-O mutation is characterized by outpocketings of tissue along lateral veins of the maize leaf and by displacement of ligule tissue from the junction of the blade and sheath into the blade.
