(n.) The thin and scarious projection from the upper end of the sheath of a leaf of grass.
(n.) A strap-shaped corolla of flowers of Compositae.
(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.
(4) To establish which inner leaf layer was required for formation of knots and ectopic ligule we used a closely linked albino mutation to mark X-ray-induced clonal sectors of wild type (kn) tissue in Kn1 plants.
(5) Wild-type internal tissue in direct contact with lg1 epidermis appears able to induce the mutant epidermis to form a rudimentary ligule.
(6) The results indicate that the lg1 gene acts tissue specifically in an early step of ligule and auricle initiation.
(7) This establishes a distinct band of cells, from which the ligule arises via periclinal divisions.
(8) We also show that the ectopic ligule in Kn1 has contributions from both the adaxial epidermal and adaxial mesophyll layer.
(9) The anticlinal divisions preceding ligule formation are altered in the mutant; therefore, the gene acts early in development, before the periclinal divisions, and possibly during basipetal vascularization.
(10) During the second stage, ligule and auricle form, blade grows more rapidly than sheath, divisions in the blade become exclusively transverse in orientation, and differentiation begins.
(11) This pattern is particularly apparent in developing adult leaves on older lg1 plants, in which sporadic ligule vestiges form.
(12) Each mutant alters the position of the ligule boundary.
(13) In a normal maize leaf, a ligule and auricles separate the blade and sheath.
(14) 14), we conclude that the information carried by the Lg1+ gene product acts earlier in development than formation of the ligule proper.
(15) Mutants homozygous for the recessive liguleless-1 (lg1) allele exhibit loss of normal ligule and auricle.
(16) The ligule, a fringe normally found at the junction of leaf blade and sheath, is often displaced and perpendicular to its normal position.
(17) In genetically mosaic leaves, when an lg1 mutant sector interrupts the normal ligule, the ligule is often displaced basipetally on the marginal side of the sector.
(18) The maize leaf is composed of a blade and a sheath, which are separated at the ligular region by a ligule and an auricle.
(19) The recessive lg1 mutation prevents formation of ligules and auricles during leaf development.
(20) Second, the dominant mutants all move the ligule boundary in the same direction.

Definition:
(n.) A kind of precious stone.
Example Sentences:
(1) This paper is a compressed version of a tutorial which was presented during the 1986 training course of the International Pharmaco-EEG Group, in Santa Margherita Ligure, Italy.
(2) This tutorial was presented during the 1986 training course of the International Pharmaco-EEG Group (IPEG) in Santa Margherita Ligure, Italy.
(3) A survey of literature data on male breast cancer is reported: on this basis the authors report their experience of five cases observed between 1980 and 1989 at Ospedale "S. Corona" Pietra Ligure, out of 500 female breast cancers treated in the same period.
