What's the difference between ligneous and lignification?
Ligneous
Definition:
(a.) Made of wood; consisting of wood; of the nature of, or resembling, wood; woody.
Example Sentences:

(2) Three possibilities are considered: the proper inflammatory lesions--granulomatous, lymphoplasmocitary and ligneous thyroiditis, the cystic formations circumscribed by the glandular tissue with inflammatory signs as well as the association of thyroid cancer with chronic thyroiditis--seldom reported in literature--upon which 2 observations have been made.
(3) A considerable number of agents have been proposed as causing ligneous conjunctivitis.
(4) Seventeen cases of ligneous conjunctivitis were studied.

(8) The origin and treatment of ligneous cellulitis are discussed.
(9) A case of ligneous conjunctivitis, which presented in the acute form and converted to a mixed form after several months is described.
(10) We report the association of ligneous conjunctivitis with middle-ear and tympanic membrane involvement in two children.
(11) The diagnosis of ligneous conjunctivitis was made by excisional biopsies in both.
(12) Ligneous conjunctivitis is a rare disease of unknown cause characterized by pseudomembranous, fibrous, woody, plaquelike deposits on the conjunctiva.
(13) On the basis of this family and previous reports, we believe that ligneous conjunctivitis is a genetic disorder inherited in an autosomal recessive pattern and that genetic counseling should be offered to the parents of affected children.
(14) These findings support the hypothesis that ligneous conjunctivitis could be the result of a lowered resistance associated with a disturbance of wound healing.
(15) The diffused floor coverings on epoxide basis, paste "Pirolik" and some types of ligneous surfaces on the basis of carbamide-formaldehyde pitch, received unfavourable hygienic assessment.
(16) Ligneous conjunctivitis tends to occur more frequently in children.
(17) The cases of ligneous conjunctivitis published since 1964 are presented in a review of the literature.
(18) On the basis of his studies on Fabry's disease, the dyscephalic syndrome of François, the ligneous conjunctivitis and the macular dystrophy of the cornea the author stresses the importance of heredity in ophthalmology.
(19) Eye and ear specimens revealed histopathologic and ultrastructural findings consistent with ligneous conjunctivitis, characterized by an amorphous, eosinophilic material with acute and chronic nongranulomatous inflammation.
(20) The success of Intal therapy in this case supports the theory that mast cells are involved in the pathogenesis of ligneous conjunctivitis.
Lignification
Definition:
(n.) A change in the character of a cell wall, by which it becomes harder. It is supposed to be due to an incrustation of lignin.
Example Sentences:
(1) An Italian "Dalita" ryegrass (Lolium italicum) and a European lucerne (Medicago sativa) were harvested at 5 different growth stages to determine the anatomical factors limiting their digestibility and in particular the effects of lignification of the tissues.
(2) The possible relationship between pectic polysaccharide-xylan-phenolic complexes and the onset of lignification in maturing tissues is discussed.
(3) The observation that the oxidation of CA by cell wall peroxidase at the expense of IAA and O2 is inhibited by genistein, a putative endogenous inhibitor of lignification in lupin hypocotyls, supports the view that the H2O2-generating system coexists with cell wall peroxidase activities involved in lignification, and that it takes place at the expense of IAA and O2.
(4) Surface area equations based on lignification of NDF accurately estimated fiber digestion and suggested that lignification was the primary reason DM and NDF digestibilities decreased with advanced maturity.
(5) It is also found that the degree of lignification of fibres and medullary cells of the herbaceous stems is related to the positions and diameters of the stems.
(6) The data suggest that beta-glucosidase-catalyzed reaction might be involved in lignification of these plant cell cultures.
(7) The regulatory significance of the rapid activation of this CAD gene and the possible existence of a second, divergent CAD gene involved in lignification during xylogenesis are discussed.
(8) We have isolated a full-length cDNA clone encoding CAD, as a molecular marker specific for lignification, by immunoscreening a lambda gt11 library containing cDNAs complementary to mRNA from elicitor-treated cell cultures of bean (Phaseolus vulgaris L.).
(9) This peroxidase-catalyzed reaction has been proposed for the plant peroxidases involved in lignification.
